POLICY POINTS: The tobacco companies prioritized blocking tobacco-control policies in tobacco-growing states and partnered with tobacco farmers to oppose tobacco-control policies. The 1998 Master Settlement Agreement, which settled state litigation against the cigarette companies, the 2004 tobacco-quota buyout, and the companies' increasing use of foreign tobacco led to a rift between the companies and tobacco farmers. In 2003, the first comprehensive smoke-free local law was passed in a major tobacco-growing state, and there has been steady progress in the region since then. Health advocates should educate the public and policymakers on the changing reality in tobacco-growing states, notably the major reduction in the volume of tobacco produced. The 5 major tobacco-growing states (Kentucky, North Carolina, South Carolina, Tennessee, and Virginia) are disproportionately affected by the tobacco epidemic, with higher rates of smoking and smoking-induced disease. These states also have fewer smoke-free laws and lower tobacco taxes, 2 evidence-based policies that reduce tobacco use. Historically, the tobacco farmers and hospitality associations allied with the tobacco companies to oppose these policies. This research is based on 5 detailed case studies of these states, which included key informant interviews, previously secret tobacco industry documents (available at http://legacy.library.ucsf.edu), and media articles. This was supplemented with additional tobacco document and media searches specifically for this article. The tobacco companies were particularly concerned about blocking tobacco-control policies in the tobacco-growing states by promoting a pro-tobacco culture, beginning in the late 1960s. Nevertheless, since 2003, there has been rapid progress in the tobacco-growing states' passage of smoke-free laws. This progress came after the alliance between the tobacco companies and the tobacco farmers fractured and hospitality organizations stopped opposing smoke

X-ray irradiation was evaluated for improving microbial safety and the quality of flue-cured tobacco during aging. Tobacco samples were irradiated at doses of 0, 1, 2, 3 and 5 kGy and stored for 12 months under normal storage conditions or in a high-humidity (RH>70%) room. Microbiological data indicated that the population of total aerobic bacteria was significantly decreased with increasing irradiation doses. In particular, a dose of 2 kGy was effective for the decontamination of fungi from the tested samples, with a 0.93 log CFU/g reduction for bacteria. The control and 1 kGy X-ray treated tobacco samples were became rotted and moldy after the 12th month, whereas those treated with 2, 3 and 5 kGy had no detectable mold during 12 months of storage at high humidity. Chemical measurements showed that irradiation up to 3 kGy did not affect the total nitrogen, nicotine, reducing and total sugars, ratio of total nitrogen to nicotine and sugar-to-nicotine ratio. Furthermore, sensory evaluation results also showed that X-ray irradiation did not affect sensory scores with irradiation at a dose <3 kGy. Based on these results, X-ray irradiation dose in the range of 2–3 kGy is recommended for the decontamination of fungi from flue-cured tobacco. - Highlights: • 2 kGy dose improved sufficiently the microbial safety of flue-cured tobacco. • The doses up to 3 kGy did not affect the chemical components. • A dose <3 kGy had no effect on sensory scores. • The recommended dose to irradiated flue-cured tobacco is the range of 2–3 kGy

Root distribution of flue-cured tobacco (variety : Kanakaprabha) in clayey and loamy sand soils was studied with the help of 32 P wick feeding technique. About 90 percent of the roots of tobacco plant in black soil on 40th day and in light soil on 60th day are present in a soil core of diameter 40 cm and depth 30 cm. On the 90th day of growth stage, no significant differences were observed in the root distribution of tobacco between the two types of soil. About 85 percent of the roots were present in a soil core of diameter 40 cm and depth 30 cm on 90th day in both the soils. (author)

The fungi isolated from 100 samples of flue-cured tobacco from 12 markets in 2 tobacco belts comprised 11 genera, including 10 species of Aspergillus. The mean percentage per sample isolated from 62 samples of tobacco from Middle Belt markets was Alternaria, 40.6%; Aspergillus niger, 47.8%; Aspergillus repens, 38.0%; and Penicillium, 25.8%. The mean percentage per sample isolated from 38 samples of tobacco from Old Belt markets was Alternaria, 74.0%; Penicillium, 52.5%; Aspergillus repens, 38.0%; and Aspergillus ruber, 36.2%. Damaged (74 samples) and nondamaged (26 samples) stored tobacco yielded species of six genera of fungi, including eight species of Aspergillus. Species of Aspergillus and Penicillium were commonly isolated from both damaged and nondamaged tobacco, whereas species of Alternaria, Cladosporium, Fusarium, and Rhizopus were isoalted more frequently from nondamaged tobacco. The fungi that occurred in the highest population in damaged tobacco were Aspergillus repens, A. niger, A. ruber, and Penicillium species. PMID:16349841

Effects of the systemic acquired resistance (SAR)-inducing compound acibenzolar-S-methyl (ASM) and the plant-growth promoting rhizobacterial mixture Bacillus subtilis A13 and B. amyloliquefaciens IN937a (GB99+GB122) were assessed on the reproduction of a tobacco cyst nematode (TCN- Globodera tabacum solanacearum) under greenhouse conditions. Two sets of two independent experiments were conducted, each involving soil or root sampling. Soil sample experiments included flue-cured tobacco cultivars with (Php+: NC71 and NC102) and without (Php-: K326 and K346) a gene (Php) suppressing TCN parasitism. Root sample experiments examined TCN root parasitism of NC71 and K326. Cultivars possessing the Php gene (Php+) were compared with Php- cultivars to assess the effects of resistance mediated via Php gene vs. induced resistance to TCN. GB99+GB122 consistently reduced nematode reproductive ratio on both Php+ and Php- cultivars, but similar effects of ASM across Php- cultivars were less consistent. In addition, ASM application resulted in leaf yellowing and reduced root weight. GB99+GB122 consistently reduced nematode development in roots of both Php+ and Php- cultivars, while similar effects of ASM were frequently less consistent. The results of this study indicate that GB99+GB122 consistently reduced TCN reproduction in all flue-cured tobacco cultivars tested, while the effects of ASM were only consistent in Php+ cultivars. Under most circumstances, GB99+GB122 suppressed nematode reproduction more consistently than ASM compared to the untreated control. PMID:22736824

Full Text Available Drought is a major environmental factor that limits crop growth and productivity. Flue-cured tobacco (Nicotiana tabacum is one of the most important commercial crops worldwide and its productivity is vulnerable to drought. However, comparative analyses of physiological, biochemical and gene expression changes in flue-cured tobacco varieties differing in drought tolerance under long-term drought stress are scarce. In this study, drought stress responses of two flue-cured tobacco varieties, LJ851 and JX6007, were comparatively studied at the physiological and transcriptional levels. After exposing to progressive drought stress, the drought-tolerant LJ851 showed less growth inhibition and chlorophyll reduction than the drought-sensitive JX6007. Moreover, higher antioxidant enzyme activities and lower levels of H2O2, Malondialdehyde (MDA, and electrolyte leakage after drought stress were found in LJ851 when compared with JX6007. Further analysis showed that LJ851 plants had much less reductions than the JX6007 in the net photosynthesis rate and stomatal conductance during drought stress; indicating that LJ851 had better photosynthetic performance than JX6007 during drought. In addition, transcriptional expression analysis revealed that LJ851 exhibited significantly increased transcripts of several categories of drought-responsive genes in leaves and roots under drought conditions. Together, these results indicated that LJ851 was more drought-tolerant than JX6007 as evidenced by better photosynthetic performance, more powerful antioxidant system, and higher expression of stress defense genes during drought stress. This study will be valuable for the development of novel flue-cured tobacco varieties with improved drought tolerance by exploitation of natural genetic variations in the future.

State laws addressing tobacco use, the leading preventable cause of death in the United States, are summarized. Laws address smoke-free indoor air, minors' access to tobacco products, advertising of tobacco products, and excise taxes on tobacco products. Legislation effective through December 31, 1998. CDC identified laws addressing tobacco control by using an on-line legal research database. CDC's findings were verified with the National Cancer Institute's State Cancer Legislative Database. Since a previous surveillance summary on state tobacco-control laws published in November 1995 (covering legislation effective through June 30, 1995), several states have enacted new restrictions or strengthened existing legislation that addresses smoke-free indoor air, minors' access to tobacco, tobacco advertising, and tobacco taxes. Five states strengthened their smoke-free indoor air legislation. All states and Washington, D.C., continued to prohibit the sale and distribution of tobacco products to minors; however, 21 states expanded minors' access laws by designating enforcement authorities, adding license suspension or revocation for sale to minors, or requiring signage. Since the 1995 report, eight additional states (a total of 19 states and Washington, D.C.) now ban vending machines from areas accessible to minors. Thirteen states restrict advertising of tobacco products, an increase of four states since the 1995 report. Although the number of states that tax cigarettes and smokeless tobacco did not change, 13 states increased excise taxes on cigarettes, and five states increased excise taxes on smokeless tobacco products. The average state excise tax on cigarettes is 38.9 cents per pack, an increase of 7.4 cents compared with the average tax in the 1995 report. State laws addressing tobacco control vary in relation to restrictiveness, enforcement and penalties, preemptions, and exceptions. The data summarizing state tobacco-control laws are available through CDC

FUELS IN TOBACCO PRODUCTION

Directory of Open Access Journals (Sweden)

2008-09-01

Full Text Available Energy production from biomass can reduce „greenhouse effect” and contribute to solving energy security especially in the agricultural households which rely on energy from fossil fuels. In Croatia fuel-cured tobacco is produced on about 5000 ha. Gross income for the whole production is about 180 000 000 kn/year. Flue-cured tobacco is a high energy consuming crop. There are two parts of energy consumption, for mechanization used for the field production (11% and, energy for bulk-curing (89%. In each case, presently used fuels of fossil origin need to be substituted by an alternative energy source of organic origin. Hereafter attention is paid to finding a more economic and ecologically acceptable fuel for curing tobacco. Curing flue-cured tobacco is done by heated air in curing burns. Various sources of heat have been used; wood, coal, oil and gas. In each case different burning facilities of different efficiency have been used. This has had an impact on curing costs and ecology. Recently, mostly used fuel has been natural gas. However, gas is getting expensive. Consequently, an alternative fuel for curing tobacco is sought for. According to literature, agricultural crops suitable for the latter purpose could be wheat, barley, maize, sorghum, sugar beet and some other annual and perennial plant species. Wooden pellets (by-products are suitable for combustion too. Ligno-cellulose fuels have been used for heating since long time. However, not sufficient research has been done from an applied point of view (Venturi and Venturi, 2003. Fuel combustion is getting more efficient with developing technological innovations. The curing barn manufacturers are offering technology for combusting wooden pellets (by-products for curing tobacco. The pellets are available on domestic market. The same technology can be used for combustion of maize grain. Within “Hrvatski duhani” research on suitability of using wooden pellets and maize grain and whole

Ali, S.; Farooq, U.

2014-01-01

This study investigates the acreage response of Flue Cured Virginia (FCV) tobacco to its own price and area under maize crop in three major FCV producing districts of Khyber Pakhtunkhwa i.e., Swabi, Mardan, and Charsadda. Data used in the study cover time series data for 1971-2011. The newly developed Auto Regressive Distributed Lag (ARDL) model for cointegration was used to estimate the short-run and long-run elasticities. The study found a long-run price elasticity of 0.33, thereby revealing that FCV acreage response to its own price is relatively inelastic. The short-run acreage response was also low (0.13) and therefore relatively inelastic. This implies that price policy could not be used as the sole instrument to affect area under FCV. The provision of some other non-price incentives may also play a significant role in increasing area under FCV in the study area. The results also show that area under maize crop negatively affect area under FCV, thereby indicating that maize crop could be considered as competing crop to FCV in the study area. The results of this study could help policy makers in identifying important determinants of acreage response of FCV tobacco crop in the study area. (author)

Using a Chlorophyll Meter to Evaluate the Nitrogen Leaf Content in Flue-Cured Tobacco (Nicotiana tabacum L.

Directory of Open Access Journals (Sweden)

Fabio Castelli

2009-06-01

Full Text Available In flue-cured tobacco N fertilizer is commonly applied during pre-planting, and very often applied again later as a growth-starter. It is generally held that the efficiency of N-fertilizer use can be improved by evaluating the leaf Nstatus after transplanting and until flowering stage. N use efficiency in this context does not refer merely to the yield but also to the quality, in the meanwhile minimizing the negative effects on the environment. To investigate these aspects, we evaluated the capacity of a Minolta model SPAD-502 chlorophyll meter to estimate the N-status in flue-cured tobacco. The aims was to verify if a relationship exists between SPAD readings and leaf N content, and if a single leaf, in a well defined stalk position, could represent the nitrogen content of the whole plant. During the years 1995 and 1996, a pot experiment was conducted using two flue-cured tobacco varieties. SPAD values, total chlorophyll, total N contents and leaf area were measured throughout the growing season, on each odd leaf stalk position. SPAD values were well-correlated with both total chlorophyll and total N leaf concentration, and the regression coefficients were higher when relationships were calculated on a leaf-area basis. For both relationships, SPAD-total chlorophyll and SPAD-total N, the best fittings were obtained with quadratic equations. One leaf stalk position alone is able to monitor the N-status of the whole plant during the first six weeks after transplanting, without distinction of year and variety effects. The SPAD measurement of one leaf per plant, throughout the vegetative growing season, is therefore a valid tool to test the N-status of the crop in a period when a required N supply is still effective.

Use of tobacco tax stamps to prevent and reduce illicit tobacco trade--United States, 2014.

Tobacco use is the leading cause of preventable disease and death in the United States. Increasing the unit price on tobacco products is the most effective tobacco prevention and control measure. Illicit tobacco trade (illicit trade) undermines high tobacco prices by providing tobacco users with cheaper-priced alternatives. In the United States, illicit trade primarily occurs when cigarettes are bought from states, jurisdictions, and federal reservation land with lower or no excise taxes, and sold in jurisdictions with higher taxes. Applying tax stamps to tobacco products, which provides documentation that taxes have been paid, is an important tool to combat illicit trade. Comprehensive tax stamping policy, which includes using digital, encrypted ("high-tech") stamps, applying stamps to all tobacco products, and working with tribes on stamping agreements, can further prevent and reduce illicit trade. This report describes state laws governing tax stamps on cigarettes, little cigars (cigarette-sized cigars), roll-your-own tobacco (RYOT), and tribal tobacco sales across the United States as of January 1, 2014, and assesses the extent of comprehensive tobacco tax stamping in the United States. Forty-four states (including the District of Columbia [DC]) applied traditional paper ("low-tech") tax stamps to cigarettes, whereas four authorized more effective high-tech stamps. Six states explicitly required stamps on other tobacco products (i.e., tobacco products other than cigarettes), and in approximately one third of states with tribal lands, tribes required tax stamping to address illicit purchases by nonmembers. No U.S. state had a comprehensive approach to tobacco tax stamping. Enhancing tobacco tax stamping across the country might further prevent and reduce illicit trade in the United States.

A field experiment was conducted to study the effects of applying different organic fertilizers (refined organic fertilizer and bio-organic fertilizer) and their combination with 20% reduced chemical fertilizers on the microbes in rhizospheric soil of flue-cured tobacco, the resistance of the tobacco against bacterial wilt, and the tobacco yield and quality. As compared with conventional chemical fertilization (CK), applying refined organic fertilizer (ROF) or bio-organic fertilizer (BIO) in combining with 20% reduced chemical fertilization increased the bacterial number and the total microbial number in the rhizospheric soil significantly. Applying BIO in combining with 20% reduced chemical fertilization also increased the actinomyces number in the rhizospheric soil significantly, with an increment of 44.3% as compared with that under the application of ROF in combining with 20% reduced chemical fertilization, but decreased the fungal number. As compared with CK, the ROF and BIO increased the carbon use capacity of rhizospheric microbes significantly, and the BIO also increased the capacity of rhizospheric microbes in using phenols significantly. Under the application of ROF and BIO, the disease incidence and the disease index of bacterial wilt were decreased by 4% and 8%, and 23% and 15.9%, and the proportions of high grade tobacco leaves increased significantly by 10.5% and 9.7%, respectively, as compared with those in CK. BIO increased the tobacco yield and its output value by 17.1% and 18.9% , respectively, as compared with ROF.

Despite recent declines in cigarette smoking prevalence, the tobacco product landscape has shifted to include emerging tobacco products* (1,2). Previous research has documented adult use of smokeless tobacco and cigarettes by state (3); however, state-specific data on other tobacco products are limited. To assess tobacco product use in the 50 U.S. states and the District of Columbia (DC), CDC and the National Cancer Institute analyzed self-reported use of six tobacco product types: cigarettes, cigars, regular pipes, water pipes, electronic cigarettes (e-cigarettes), and smokeless tobacco products among adults aged ≥18 years using data from the 2014-2015 Tobacco Use Supplement to the Current Population Survey (TUS-CPS). Prevalence of ever-use of any tobacco product ranged from 27.0% (Utah) to 55.4% (Wyoming). Current (every day or some days) use of any tobacco product ranged from 10.2% (California) to 27.7% (Wyoming). Cigarettes were the most common currently used tobacco product in all states and DC. Among current cigarette smokers, the proportion who currently used one or more other tobacco products ranged from 11.5% (Delaware) to 32.3% (Oregon). Differences in tobacco product use across states underscore the importance of implementing proven population-level strategies to reduce tobacco use and expanding these strategies to cover all forms of tobacco marketed in the United States. Such strategies could include comprehensive smoke-free policies, tobacco product price increases, anti-tobacco mass media campaigns, and barrier-free access to clinical smoking cessation resources (1,4).

Availability of tobacco cessation services in substance use disorder treatment programs: Impact of state tobacco control policy.

Abraham, Amanda J; Bagwell-Adams, Grace; Jayawardhana, Jayani

2017-08-01

Given the high prevalence of smoking among substance use disorder (SUD) patients, the specialty SUD treatment system is an important target for adoption and implementation of tobacco cessation (TC) services. While research has addressed the impact of tobacco control on individual tobacco consumption, largely overlooked in the literature is the potential impact of state tobacco control policies on availability of services for tobacco cessation. This paper examines the association between state tobacco control policy and availability of TC services in SUD treatment programs in the United States. State tobacco control and state demographic data (n=51) were merged with treatment program data from the 2012 National Survey of Substance Abuse Treatment Services (n=10.413) to examine availability of TC screening, counseling and pharmacotherapy services in SUD treatment programs using multivariate logistic regression models clustered at the state-level. Approximately 60% of SUD treatment programs offered TC screening services, 41% offered TC counseling services and 26% offered TC pharmacotherapy services. Results of multivariate logistic regression showed the odds of offering TC services were greater for SUD treatment programs located in states with higher cigarette excise taxes and greater spending on tobacco prevention and control. Findings indicate cigarette excise taxes and recommended funding levels may be effective policy tools for increasing access to TC services in SUD treatment programs. Coupled with changes to insurance coverage for TC under the Affordable Care Act, state tobacco control policy tools may further reduce tobacco use in the United States. Published by Elsevier Ltd.

Microbes on aging flue-cured tobaccos (ATFs) improve the aroma and other qualities desirable in products. Understanding the relevant organisms would picture microbial community diversity, metabolic potential, and their applications. However, limited efforts have been made on characterizing the microbial quality and functional profiling. Herein, we present our investigation of the bacterial diversity and predicted potential genetic capability of the bacteria from two AFTs using 16S rRNA gene sequences and phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) software. The results show that dominant bacteria from AFT surfaces were classified into 48 genera, 36 families, and 7 phyla. In addition, Bacillus spp. was found prevalent on both ATFs. Furthermore, PICRUSt predictions of bacterial community functions revealed many attractive metabolic capacities in the AFT microbiota, including several involved in the biosynthesis of flavors and fragrances and the degradation of harmful compounds, such as nicotine and nitrite. These results provide insights into the importance of AFT bacteria in determining product qualities and indicate specific microbial species with predicted enzymatic capabilities for the production of high-efficiency flavors, the degradation of undesirable compounds, and the provision of nicotine and nitrite tolerance which suggest fruitful areas of investigation into the manipulation of AFT microbiota for AFT and other product improvements.

Correlation between the state of cure of thermosetting resins and their properties

International Nuclear Information System (INIS)

Haffane, N.; Benameur, T.; Granger, R.; Vergnaud, J.M.

1996-01-01

Thermosetting resins, in the same way as polymers, are more and more used for coating metal sheets, in order to bring various interesting properties. An important problem arises with the cure of the thermoset, the process of cure being complex with heating conduction and convection and the heat generated by the cure reaction. The kinetics of the heat evolved from the overall cure reaction is determined through calorimetry experiments in scanning mode. The state of cure at time t is expressed by the heat generated by reaction up to time t as a fraction of the total heat generated. A numerical model taking all the facts into account is able to evaluate the profile of the state of cure developed through the thickness of the thermoset. The state of cure which derives from a theoretical point of view is correlated with some properties of interest for the coating, such as the hardness and the resistance to liquids. The resistance to water and ethanol is evaluated by determining the kinetics of absorption which is controlled by diffusion. copyright 1996 American Institute of Physics

Tobacco use remains the leading cause of preventable disease and death in the United States (1). Despite declining cigarette smoking prevalence among U.S. adults, shifts in the tobacco product landscape have occurred in recent years (2,3). Previous estimates of tobacco product use among U.S. adults were obtained from the National Adult Tobacco Survey, which ended after the 2013-2014 cycle. This year, CDC and the Food and Drug Administration (FDA) assessed the most recent national estimates of tobacco product use among adults aged ≥18 years using, for the first time, data from the 2015 National Health Interview Survey (NHIS), an annual, nationally representative, in-person survey of the noninstitutionalized U.S. civilian population. The 2015 NHIS adult core questionnaire included 33,672 adults aged ≥18 years, reflecting a 55.2% response rate. Data were weighted to adjust for differences in selection probability and nonresponse, and to provide nationally representative estimates. In 2015, 20.1 % of U.S. adults currently (every day or some days) used any tobacco product, 17.6% used any combustible tobacco product, and 3.9% used ≥2 tobacco products. By product, 15.1% of adults used cigarettes; 3.5% used electronic cigarettes (e-cigarettes); 3.4% used cigars, cigarillos, or filtered little cigars; 2.3% used smokeless tobacco; and 1.2% used regular pipes, water pipes, or hookahs.* Current use of any tobacco product was higher among males; persons aged product was 47.2% among adults with serious psychological distress compared with 19.2% among those without serious psychological distress. Proven population-level interventions that focus on the diversity of tobacco product use are important to reducing tobacco-related disease and death in the United States (1).

Tauras, John A.; Xu, Xin; Huang, Jidong; King, Brian; Lavinghouze, S. Rene; Sneegas, Karla S.; Chaloupka, Frank J.

2018-01-01

This research is the first nationally representative study to examine the relationship between actual state-level tobacco control spending in each of the 5 CDC’s Best Practices for Comprehensive Tobacco Control Program categories and cigarette sales. We employed several alternative two-way fixed-effects regression techniques to estimate the determinants of cigarette sales in the United States for the years 2008–2012. State spending on tobacco control was found to have a negative and significant impact on cigarette sales in all models that were estimated. Spending in the areas of cessation interventions, health communication interventions, and state and community interventions were found to have a negative impact on cigarette sales in all models that were estimated, whereas spending in the areas of surveillance and evaluation, and administration and management were found to have negative effects on cigarette sales in only some models. Our models predict that states that spend up to seven times their current levels could still see significant reductions in cigarette sales. The findings from this research could help inform further investments in state tobacco control programs. PMID:29652890

Adolescent Tobacco Use in Urban Versus Rural Areas of the United States: The Influence of Tobacco Control Policy Environments.

Science.gov (United States)

Pesko, Michael F; Robarts, Adam M T

2017-07-01

Adults and adolescents who reside in rural areas of the United States are traditionally more likely to be tobacco users. This urban-rural disparity remains largely unexplained and, more recently, it is unclear what impact the emergence of electronic cigarettes (e-cigarettes) has had on adolescent tobacco use in urban and rural areas. Our objective is to evaluate the influence of sociodemographics and tobacco control policy environments on adolescent tobacco use in urban versus rural areas, as well as to identify the effect of e-cigarettes on traditional patterns of urban-rural tobacco use. This study analyzes repeated cross-sectional data from the National Youth Tobacco Survey for the years 2011-2014. We estimate the associations between rural residence, cigarette taxes, tobacco advertisement exposure, and ease of access to tobacco with six tobacco use outcomes: current (past 30-day) use of cigarettes, e-cigarettes, cigars, smokeless tobacco, multiple tobacco products, and any tobacco. E-cigarette use among urban youths aged 11-17 years in the United States increased from .82% in 2011 to 8.62% in 2014 (p e-cigarettes. Our predictors account for approximately 40% of the difference in urban-rural cigarette use. Sociodemographics, cigarette taxes, and tobacco advertisement exposure are significant predictors of adolescent tobacco use in the United States but do not entirely explain urban-rural disparities. In addition, e-cigarettes appear to be rapidly changing traditional patterns of tobacco use, particularly in urban areas. Copyright © 2017 Society for Adolescent Health and Medicine.

Combustible and smokeless tobacco use causes adverse health outcomes, including cardiovascular disease and multiple types of cancer (1,2). Standard approaches for measuring tobacco use include self-reported surveys of use and consumption estimates based on tobacco excise tax data (3,4). To provide the most recently available tobacco consumption estimates in the United States, CDC used federal excise tax data to estimate total and per capita consumption during 2000-2015 for combustible tobacco (cigarettes, roll-your-own tobacco, pipe tobacco, small cigars, and large cigars) and smokeless tobacco (chewing tobacco and dry snuff). During this period, total combustible tobacco consumption decreased 33.5%, or 43.7% per capita. Although total cigarette consumption decreased 38.7%, cigarettes remained the most commonly used combustible tobacco product. Total noncigarette combustible tobacco (i.e., cigars, roll-your-own, and pipe tobacco) consumption increased 117.1%, or 83.8% per capita during 2000-2015. Total consumption of smokeless tobacco increased 23.1%, or 4.2% per capita. Notably, total cigarette consumption was 267.0 billion cigarettes in 2015 compared with 262.7 billion in 2014. These findings indicate that although cigarette smoking declined overall during 2000-2015, and each year from 2000 to 2014, the number of cigarettes consumed in 2015 was higher than in 2014, and the first time annual cigarette consumption was higher than the previous year since 1973. Moreover, the consumption of other combustible and smokeless tobacco products remains substantial. Implementation of proven tobacco prevention interventions (5) is warranted to further reduce tobacco use in the United States.

Common state mechanisms regulating tribal tobacco taxation and sales, the USA, 2015.

Science.gov (United States)

DeLong, Hillary; Chriqui, Jamie; Leider, Julien; Chaloupka, Frank J

2016-10-01

Native American tribes, as sovereign nations, are exempt from state tobacco excise taxation, and self-govern on-reservation activity in the USA. Under Federal law, state excise taxes are owed by non-members purchasing tobacco on tribal land, but states are limited in how they enforce or collect these taxes. This study highlights the various policy approaches that states have taken to regulate tobacco sales on tribal lands given jurisdictional challenges. State laws (statutes, regulations and case law), Attorney General opinions, and revenue notices and rulings effective as of 1 January 2015 for all 50 states and the District of Columbia were compiled using Boolean searches in Lexis-Nexis and Westlaw. Laws were limited to those addressing taxation compacts or tobacco sales involving tribal entities. Master Settlement Agreement laws and non-codified tribal codes/compacts were excluded. Twenty of the 34 states with tribal lands address tribal tobacco sales. Fourteen states address intergovernmental compacts: 11 are tobacco specific, and suggest or require specific provisions. Fifteen states address tribal tax stamps: 2 explicitly prohibit stamping tribally sold products, 9 stamp all products, and 4 stamp some. Prepayment of excise tax is required in 12 states: 6 on all products, 4 on products in excess of quota, and 2 on products sold by non-tribal retailers. 6 states use quotas to limit tax-free tobacco available to tribes. Many states with a tribal presence have no formal strategies for non-members purchasing tobacco on tribal lands. Formalising policies and harmonising tax rates may assist states in collecting tax revenue from non-tribal consumers. Published by the BMJ Publishing Group Limited.

Full Text Available A field experiment was carried out at Tobacco Research Station Khan Ghari, Mardan, (NWFP- Pakistan during spring 2003 to study the impact of herbicides on some agronomic and chemical characteristics of flue-cured virginia (FCV tobacco (Nicotiana tabacum L.. The experiment was laid out in RCB design, replicated four times with ten treatments, comprising hand weeding, weedy check, pre-transplanting herbicides; S-metalocholar @ 1.92, pendimethalin (EC @ 1.00, pendimethalin (CS @ 1.00, and butralin @ 1.44 kg a.i ha-1 and the post-transplanting herbicides include; clodinafop @ 0.04, fenoxaprop-p-ethyl @ 1.00, acetochlor @ 0.125 and glyphosate @ 0.95 kg a.i ha-1. None of the herbicides except S-metalocholar had a phytotoxic effect on tobacco. All the parameters except the number of leaves plant-1 were significantly affected by different treatments. The highest (228.3 weeds density m-2 was observed in weedy check while minimum (69 was recorded in pendimethalin (EC treatment. The maximum grade index of 74.60% was recorded in acetochlor and minimum grade index of 53.88% was recorded in S-metalocholar treatments. Nicotine (% was higher in pendimethalin (EC treated plots with 2.362%; however it was comparable to all other treatments. The maximum percent reducing sugar of 18.22% was recorded in pendimethalin (CS treatment, while minimum of 12.42% reducing sugar was recorded in weedy check. Similarly maximum yield of 2465 kg ha-1 was recorded in pendimethalin (EC treatment and minimum yield of 1703 kg ha-1 was recorded in weedy check (control treatment. Thus it can be concluded from the experiment that herbicides proved effective against weeds and their growth and promoted tobacco quality and yield. Hence the use of herbicides not only increases the net income of the farmers but also will make the weed seed bank poorer.

Objectives. We assessed the prevalence and sociodemographic correlates of tobacco use among US adults. Methods. We used data from the 2009–2010 National Adult Tobacco Survey, a national landline and cell phone survey of adults aged 18 years and older, to estimate current use of any tobacco; cigarettes; cigars, cigarillos, or small cigars; chewing tobacco, snuff, or dip; water pipes; snus; and pipes. We stratified estimates by gender, age, race/ethnicity, education, income, sexual orientation, and US state. Results. National prevalence of current use was 25.2% for any tobacco; 19.5% for cigarettes; 6.6% for cigars, cigarillos, or small cigars; 3.4% for chewing tobacco, snuff, or dip; 1.5% for water pipes; 1.4% for snus; and 1.1% for pipes. Tobacco use was greatest among respondents who were male, younger, of non-Hispanic “other” race/ethnicity, less educated, less wealthy, and lesbian, gay, bisexual, or transgender. Prevalence ranged from 14.1% (Utah) to 37.4% (Kentucky). Conclusions. Tobacco use varies by geography and sociodemographic factors, but remains prevalent among US adults. Evidence-based prevention strategies are needed to decrease tobacco use and the health and economic burden of tobacco-related diseases. PMID:22994278

A field experiment with 15 N isotope tracing micro-plots was carried out to study the effects of basal N fertilizer application time (15 d, 30 d before the transplanting) of flue-cured tobacco (FCT) seedlings and nitrogen fertilization (with N and without N) on growth and development, nicotine concentrations and sources of nicotine N of FCT in Laowan (N 31 degree 27', E 111 degree 14', 1 130 m above sea level), a main tobacco production area of Xiangfan city, Hubei province. The results showed that both dry matter accumulation and nicotine concentrations of different parts of FCT increased with growing of plants. The concentrations of nicotine decreased with the ascending of leaf position before topping period, but just opposite after the removal of apex. The proportion of nicotine N from fertilizer to total nicotine N decreased with growing of FCT plants and the rising of leaf position. Applying N fertilizer significantly increased dry matter accumulation of shoot and the nicotine concentrations of different poisional tobacco leaves by 2.1-2.7 fold and 0.1-0.7 fold respectively. Compared with the basal fertilization time 15 d before transplanting, applying basal fertilizer 30 d before transplanting increased the dry matter accumulation and nicotine concentrations of flue-cured tobacco by 2.2%-8.0% and 6.3%-18.5% respectively. There was no significant effects of basal N fertilization time on the proportion of nicotine-N from fertilizer in organs of FCT plants at mature stage. These results suggested that properly putting forward the basal N fertilization time before transplanting make for decrease of nicotine concentrations and improvement of quality of FCT leaves, so as to improve its industrial utilities.

Noncigarette tobacco products are increasingly popular among youth, especially cigarette smokers. Understanding multiple tobacco product use is necessary to assess the effects of tobacco products on population health. This study examines multiple tobacco product use and associated risk factors among US youth. Estimates of current use were calculated for cigarettes, cigars, smokeless tobacco, hookah, e-cigarettes, pipes, bidis, kreteks, snus, and dissolvable tobacco by using data from the 2012 National Youth Tobacco Survey (n = 24 658), a nationally representative sample of US middle and high school students. Associations between use patterns and demographic characteristics were examined by using multinomial logistic regression. Among youth, 14.7% currently use 1 or more tobacco products. Of these, 2.8% use cigarettes exclusively, and 4% use 1 noncigarette product exclusively; 2.7% use cigarettes with another product (dual use), and 4.3% use 3 or more products (polytobacco use). Twice as many youth use e-cigarettes alone than dual use with cigarettes. Among smokers, polytobacco use was significantly associated with male gender (adjusted relative risk ratio [aRRR] = 3.71), by using flavored products (aRRR = 6.09), nicotine dependence (aRRR = 1.91), tobacco marketing receptivity (aRRR = 2.52), and perceived prevalence of peer use of tobacco products (aRRR = 3.61, 5.73). More than twice as many youth in the United States currently use 2 or more tobacco products than cigarettes alone. Continued monitoring of tobacco use patterns is warranted, especially for e-cigarettes. Youth rates of multiple product use involving combustible products underscore needs for research assessing potential harms associated with these patterns.

Full Text Available Over the last three decades, it has been frequently reported that the properties of dental restorative composites cured with argon laser are similar or superior to those achieved with conventional halogen and light emitting diode (LED curing units. Whereas laser curing is not dependent on the distance between the curing unit and the material, such distance represents a drawback for conventional curing units. However, a widespread clinical application of this kind of laser remains difficult due to cost, heavy weight, and bulky size. Recently, with regard to the radiation in the blue region of the spectrum, powerful solid-state lasers have been commercialized. In the current research, CAD (computer-aided design/CAM (computer-aided manufacturing assisted solid-state lasers were employed for curing of different dental restorative composites consisting of micro- and nanoparticle-reinforced materials based on acrylic resins. Commercial LED curing units were used as a control. Temperature rise during the photopolymerisation process and bending properties were measured. By providing similar light energy dose, no significant difference in temperature rise was observed when the two light sources provided similar intensity. In addition, after 7 days since curing, bending properties of composites cured with laser and LED were similar. The results suggested that this kind of laser would be suitable for curing dental composites, and the curing process does not suffer from the tip-to-tooth distance.

Schmidt, Allison M; Ranney, Leah M; Goldstein, Adam O

2014-12-04

Tobacco use, the leading cause of preventable death in the U.S., can be reduced through state-level tobacco prevention and cessation programs. In the absence of research about how to communicate the need for these programs to policymakers, this qualitative study aimed to understand the motivations and priorities of policymakers in North Carolina, a state that enacted a strong tobacco control program from 2003-2011, but drastically reduced funding in recent years. Six former legislators (three Democrats, three Republicans) and three lobbyists for health organizations were interviewed about their attitudes towards tobacco use, support of state-funded programs, and reactions to two policy briefs. Five themes emerged: (1) high awareness of tobacco-related health concerns but limited awareness of program impacts and funding, (2) the primacy of economic concerns in making policy decisions, (3) ideological differences in views of the state's role in tobacco control, (4) the impact of lobbyist and constituent in-person appeals, and (5) the utility of concise, contextualized data. These findings suggest that building relationships with policymakers to communicate ongoing program outcomes, emphasizing economic data, and developing a constituent advocacy group would be valuable to encourage continued support of state tobacco control programs.

Evaluation of deoxynivalenol production in dsRNA Carrying and Cured Fusarium graminearum isolates by AYT1 expressing transformed tobacco

Directory of Open Access Journals (Sweden)

Samira Shahbazi

2015-12-01

Full Text Available Introduction: Fusarium head blight (FHB, is the most destructive disease of wheat, producing the mycotoxin deoxynivalenol, a protein synthesis inhibitor, which is harmful to humans and livestock. dsRNAmycoviruses-infected-isolates of Fusariumgraminearum, showed changes in morphological and pathogenicity phenotypes including reduced virulence towards wheat and decreased production of trichothecene mycotoxin (deoxynivalenol: DON. Materials and methods: Previous studies indicated that over expression of yeast acetyl transferase gene (ScAYT1 encoding a 3-O trichothecene acetyl transferase that converts deoxynivalenol to a less toxic acetylated form, leads to suppression of the deoxynivalenol sensitivity in pdr5 yeast mutants. To identify whether ScAYT1 over-expression in transgenic tobacco plants can deal with mycotoxin (deoxynivalenol in fungal extract and studying the effect of dsRNA contamination on detoxification and resistance level, we have treated T1 AYT1 transgenic tobacco seedlings with complete extraction of normal F. graminearum isolate carrying dsRNA metabolites. First, we introduced AYT1into the model tobacco plants through Agrobacterium-mediated transformation in an attempt to detoxify deoxynivalenol. Results: In vitro tests with extraction of dsRNA carrying and cured isolates of F. graminearum and 10 ppm of deoxynivalenol indicated variable resistance levels in transgenic plants. Discussion and conclusion: The results of this study indicate that the transgene expression AYT1 and Fusarium infection to dsRNA can induce tolerance to deoxynivalenol, followed by increased resistance to Fusarium head blight disease of wheat.

The development of Tobacco Harm Prevention Law in Vietnam: stakeholder tensions over tobacco control legislation in a state owned industry.

2011-09-18

Building on its National Tobacco Control Policy initiated in 2000, Vietnam is currently considering introducing a comprehensive law to strengthen the implementation of tobacco control policy. This study analyses the positions of key stakeholders in the development of tobacco control legislation in the context of a largely state-owned industry, and discusses their implications for the policy process. Several qualitative methods were employed for the study including: literature review and documentary analysis; key informant interview; focus groups discussion; and key stakeholders survey. The Ministry of Health, Ministry of Trade and Industry, and Ministry of Finance are key players in the tobacco control policy and legislation, representing competing bureaucratic interests over health, macro-economy and revenue. High-ranking officials, including the Communist Party and National Assembly members, take a rather relaxed position reflecting the low political stakes placed on tobacco issues. The state-owned tobacco industry is regarded as an important contributor to the government revenue and gross domestic product, and the relative weight on health and socioeconomic issues placed by stakeholders determine their positions on tobacco control. Overall, short-term economic interests have more immediate influence in setting policy directions, with the consequences of health gains perceived as relegated to a distant future. This was reflected in the position of tobacco control advocates, including MOH, that presented with reluctance in insisting on some tobacco control strategies revealing a mixture attitude of concessions to the socioeconomic uncertainties and a sense of bargaining to win the strategies that are more likely to be accepted. The state-ownership of tobacco industry poses a major paradox within the government that benefits from manufacturing of tobacco products and is also responsible for controlling tobacco consumption.

2012-01-01

In this paper the network structure of e-beam cured DGEBF based epoxy resins is investigated. Two epoxy systems, having different reactivity and cured in different process conditions, were analyzed through solid state NMR spectroscopy. The analysis shows that the more reactive system has higher cross-linking density and higher uniformity of network distribution. Similar information were obtained, in a previous work, on the same systems through dynamic mechanical thermal analysis. It is worth noting that unlike DMTA tests, which interfere with the molecular structure of the analyzed material, due to the heating during the analysis itself, more reliable information, without any artefact, are obtained by solid state NMR, carried out at constant room temperature. - Highlights: ► The structure of two e-beam cured epoxy systems is investigated through solid state NMR. ► The aim is to have direct information about the structure without inducing modifications. ► The different molecular structures are able to emphasize the response of solid state NMR. ► T 1 H, T 1ρ H and T CH measurements indicate different cross-linking degrees. ► The NMR results are in agreement with DMTA analysis performed in a previous paper.

True cures in health care are rare but likely not for long. The high price tag that accompanies a cure along with its rapid uptake create challenges in the financing of cures by public and private payers. In the US, the disaggregated nature of health insurance system adds to this challenge as patients frequently churn across multiple health plans. This creates a 'free-rider' problem, where no one health plan has the incentive to invest in cure since the returns will be scattered over many health plans. Here, a new health currency is proposed as a generalized version of a social impact bond that has the potential to solve this free-rider problem, as it can be traded not only between public and private payers but also within the private sector. An ensuing debate as to whether and how to develop such a currency can serve the US health care system well.

Full Text Available Tobacco use, the leading cause of preventable death in the U.S., can be reduced through state-level tobacco prevention and cessation programs. In the absence of research about how to communicate the need for these programs to policymakers, this qualitative study aimed to understand the motivations and priorities of policymakers in North Carolina, a state that enacted a strong tobacco control program from 2003–2011, but drastically reduced funding in recent years. Six former legislators (three Democrats, three Republicans and three lobbyists for health organizations were interviewed about their attitudes towards tobacco use, support of state-funded programs, and reactions to two policy briefs. Five themes emerged: (1 high awareness of tobacco-related health concerns but limited awareness of program impacts and funding, (2 the primacy of economic concerns in making policy decisions, (3 ideological differences in views of the state’s role in tobacco control, (4 the impact of lobbyist and constituent in-person appeals, and (5 the utility of concise, contextualized data. These findings suggest that building relationships with policymakers to communicate ongoing program outcomes, emphasizing economic data, and developing a constituent advocacy group would be valuable to encourage continued support of state tobacco control programs.

Waterpipe tobacco smoking (WTS) is an increasingly prevalent form of tobacco use in the United States. Its appeal may stem from its social, ritualistic, and aesthetic nature. Our aim in this study was to understand WTS as a social ritual with the goal of informing prevention efforts. We conducted a covert observational study consisting of 38 observation sessions in 11 WTS establishments in 3 U.S. cities. Data collection was based on an established conceptual framework describing ritualistic elements of tobacco use. Iterative codebook development and qualitative thematic synthesis were used to analyze data. Atmospheres ranged from quiet coffee shop to boisterous bar party environments. While some children and older adults were present, the majority of clientele were young adults. Men and women were evenly represented. However, there were 19 occurrences of a male smoking by himself, but no women smoked alone. The vast majority (94%) of the clientele were actively smoking waterpipes. All 83 observed groups manifested at least 1 of the ritual elements of our conceptual framework, while 41 of the 83 observed groups (49%) demonstrated all 4 ritual elements. Despite its heterogeneity, WTS is often characterized by 1 or more established elements of a tobacco-related social ritual. It may be valuable for clinical and public health interventions to acknowledge and address the ritualistic elements and social function of WTS. © The Author 2014.

The use of instrumental neutron activation analysis (INAA) in determining selected elements in biological materials has been reported by numerous authors. Some of these have detailed the use of INAA to determine an elemental analysis in tobaccos of various geographical origins. This paper describes the first use of INAA to measure the distribution of selected inorganic elements within the tobacco leaf at a single plant stalk position for one tobacco curing routine. Three replicate plots of a common bright tobacco cultivar were grown under normal cultural conditions characteristic for the bright variety. The tobacco leaves were sampled at selected positions in the leaf. The bright tobacco was cured in a conventional flue-curing barn using standard practices. Immediately after collection, each individual sample was freeze-dried, crushed and sampled. The leaf midrib samples were prepared using a similar procedure. A subsample of about 100 mg was taken from each sample, sealed in a polyethyelene bag, irradiated in a thermal neutron flux of 2 x 10 17 n-m -2 -s -1 in a pneumatic rabbit system, and subsequently counted to obtain the reported data. A standard reference material was used as a comparator to yield relative elemental concentrations for Ca, Mg, Mn, Na, K, Cl, and Br. The data show that chlorine, potassium, sodium and calcium have definite concentration trends within the tobacco leaf. The data also show that some elements, e,g, Mn, were more uniformly distributed throughout the leaf. (author)

2012-02-01

We examined health effects associated with 3 tobacco control interventions in Washington State: a comprehensive state program, a state policy banning smoking in public places, and price increases. We used linear regression models to predict changes in smoking prevalence and specific tobacco-related health conditions associated with the interventions. We estimated dollars saved over 10 years (2000-2009) by the value of hospitalizations prevented, discounting for national trends. Smoking declines in the state exceeded declines in the nation. Of the interventions, the state program had the most consistent and largest effect on trends for heart disease, cerebrovascular disease, respiratory disease, and cancer. Over 10 years, implementation of the program was associated with prevention of nearly 36,000 hospitalizations, at a value of about $1.5 billion. The return on investment for the state program was more than $5 to $1. The combined program, policy, and price interventions resulted in reductions in smoking and related health effects, while saving money. Public health and other leaders should continue to invest in tobacco control, including comprehensive programs.

National Cancer Institute's leadership role in promoting State and Community Tobacco Control research.

Ginexi, Elizabeth M; Vollinger, Robert E

2016-10-01

The National Cancer Institute (NCI) has been at the vanguard of funding tobacco control research for decades with major efforts such as the Community Intervention Trial for Smoking Cessation (COMMIT) in 1988 and the American Stop Smoking Intervention Study (ASSIST) in 1991, followed by the Tobacco Research Initiative for State and Community Interventions in 1999. Most recently, in 2011, the NCI launched the State and Community Tobacco Control (SCTC) Research Initiative to address gaps in secondhand smoke policies, tax and pricing policies, mass media countermeasures, community and social norms and tobacco marketing. The initiative supported large scale research projects and time-sensitive ancillary pilot studies in response to expressed needs of state and community partners. This special issue of Tobacco Control showcases exciting findings from the SCTC. In this introductory article, we provide a brief account of NCI's historical commitment to promoting research to inform tobacco control policy. Published by the BMJ Publishing Group Limited.

Smokeless tobacco has been actively promoted by tobacco companies using endorsements by major sport figures, and research indicates that tobacco advertising can lead to youth initiation of tobacco use (1,2). Television and radio advertisements for cigarettes and smokeless tobacco have been prohibited since 1969,* and the 1998 Master Settlement Agreement(†) further prohibited tobacco companies from targeting youths with tobacco product advertisements in specified areas. In 2010, the Food and Drug Administration (FDA), under authority of the 2009 Family Smoking Prevention and Tobacco Control Act (FSPTCA), prohibited tobacco-brand sponsorship (i.e., sponsorship of sports and entertainment events or other social or cultural events using the tobacco brand name or anything identifiable with any brand of cigarettes or smokeless tobacco).(§) However, corporate-name tobacco sponsorship (i.e., sponsorship using the name of the corporation that manufactures regulated tobacco products) is still permitted under certain conditions.(¶) To monitor tobacco advertising and promotional activities in sports in the United States, CDC analyzed trends in sports-related marketing expenditures for cigarettes and smokeless tobacco during 1992-2013 using data from the Federal Trade Commission (FTC). During 1992-2013, sports-related marketing expenditures, adjusted by the consumer price index to constant 2013 dollars, decreased significantly for both cigarettes (from $136 million in 1992 to $0 in 2013) and smokeless tobacco (from $34.8 million in 1992 to $2.1 million in 2013). During 2010-2013, after the prohibition of tobacco-brand sponsorship in sports under the FSPTCA, cigarette manufacturers reported no spending (i.e., $0) on sports-related advertising and promotional activities; in contrast, smokeless tobacco manufacturers reported expenditures of $16.3 million on advertising and promoting smokeless tobacco in sports during 2010-2013. These findings indicate that despite prohibitions

The political economy of tobacco and poverty alleviation in Southeast Asia: contradictions in the role of the state.

Barraclough, Simon; Morrow, Martha

2010-03-01

Of the members of the Association of Southeast Asian Nations (ASEAN), all but Indonesia have embraced the Framework Convention on Tobacco Control and all endorse some form of tobacco control policy. Nevertheless, except for Brunei, all these states are, to varying degrees, complicit in investing in or promoting the tobacco industry, often using the justification of poverty alleviation. Tobacco use is the major preventable cause of illness and death among the populations of these countries. Claims that tobacco alleviates poverty in developing countries have increasingly been discredited: thus continuing state support for the industry represents a fundamental paradox. Using primary documents from governments and the tobacco industry, and published studies investigating tobacco and poverty, this article explores the contradictions inherent in the state seeking to prevent tobacco use in the interests of health, while actively promoting tobacco for the economic benefit of its citizens. These contradictions result in both symbolic and substantial harm to tobacco control efforts: tobacco production is legitimized, rational policy principles are violated, direct cooperation between the state and multinational tobacco corporations is made possible with associated opportunities for mollifying control policies, and different state agencies work at cross purposes. Although tobacco exports within the Association of Southeast Asian Nations (ASEAN) also threaten the group's health solidarity, it is argued that divestiture of state ownership of capital in tobacco corporations and a commitment by states not to promote tobacco are urgently required if the Convention is to have full effect both in the countries of the region and in other states that have ratified it.

Consumption of cigarettes and combustible tobacco--United States, 2000-2011.

Science.gov (United States)

2012-08-03

Smoking cigarettes and other combustible tobacco products causes adverse health outcomes, particularly cancer and cardiovascular and pulmonary diseases. A priority of the U.S. Department of Health and Human Services is to develop innovative, rapid-response surveillance systems for assessing changes in tobacco use and related health outcomes. The two standard approaches for measuring smoking rates and behaviors are 1) surveying a representative sample of the public and asking questions about personal smoking behaviors and 2) estimating consumption based on tobacco excise tax data. Whereas CDC regularly publishes findings on national and state-specific smoking rates from public surveys, CDC has not reported consumption estimates. The U.S. Department of Agriculture (USDA), which previously provided such estimates, stopped reporting on consumption in 2007. To estimate consumption for the period 2000-2011, CDC examined excise tax data from the U.S. Department of Treasury's Alcohol and Tobacco Tax and Trade Bureau (TTB); consumption estimates were calculated for cigarettes, roll-your-own tobacco, pipe tobacco, and small and large cigars. From 2000 to 2011, total consumption of all combustible tobacco decreased from 450.7 billion cigarette equivalents to 326.6, a 27.5% decrease; per capita consumption of all combustible tobacco products declined from 2,148 to 1,374, a 36.0% decrease. However, while consumption of cigarettes decreased 32.8% from 2000 to 2011, consumption of loose tobacco and cigars increased 123.1% over the same period. As a result, the percentage of total combustible tobacco consumption composed of loose tobacco and cigars increased from 3.4% in 2000 to 10.4% in 2011. The data suggest that certain smokers have switched from cigarettes to other combustible tobacco products, most notably since a 2009 increase in the federal tobacco excise tax that created tax disparities between product types.

A simple analytical method was developed to simultaneously determine thiamethoxam and its metabolite, clothianidin, in fresh tobacco leaf, soil and cured tobacco leaf using liquid chromatography with tandem mass spectrometry. Thiamethoxam and clothianidin in tobacco and soil samples were extracted with acetonitrile containing 0.1% formic acid and purified using an NH 2 -SPE column. The optimized method provided good linearity with coefficients of determination R 2  ≥ 0.9981. The limits of detection and quantification were between 0.006-0.12 and 0.02-0.4 mg/kg, respectively. Intra- and inter-day recovery assays were used to validate the established method. The average recoveries of thiamethoxam and clothianidin in fresh tobacco leaf, soil and cured tobacco leaf were 75.04-100.47%, 75.86-86.40% and 89.83-99.39%, respectively. The intra- and inter-day relative standard deviations were all clothianidin residues in actual tobacco and soil samples. The results indicated that the established method met the requirements for the analysis of trace amounts of thiamethoxam and clothianidin in fresh tobacco leaf, soil and cured tobacco leaf.

A field experiment with 15 N isotope tracing micro-plots was carried out to study the effects of basal N fertilizer application time (0 d, 15 d, 30 d before the transplanting) on the yields, market values and N uptake, utilization and distribution in different organs of flue-cured tobacco (FCT) in two ecological tobacco production areas (Zhaojiashan and Laowan) of Xiangfan City, Hubei Province. The results showed that supplying N fertilizer significantly increased the yields and market values of FCT by 13% ∼ 40% and 14% ∼ 35% for the experimental site of Zhaojiashan (lower altitude) and Laowan (higher altitude), respectively. Compared to applying basal fertilizer at 0 d before transplanting, applying basal fertilizer at 15 d or 30 d before transplanting increased the market values by 10% ∼ 30% (P < 0.05). And early application of basal N fertilizer (30 d before transplanting) increased N accumulation by 8% ∼ 26% as compared with that of applying basal N fertilizer at 0 d or 15 d before transplanting in the two ecological areas. There was no significant effects of basal N application time on N fertilizer efficiency in lower altitude site, but increasing by 3% ∼ 6% in higher altitude site. These results indicated that properly earlier (15 d for example) supplication of basal N fertilizer could improve the N fertilizer efficiency, and thus increase the yields and market values of FCT, especially in higher altitude areas with less sunshine and lower temperature.

Dry Thai traditional tobacco (Nicotiana Tabacum L.) production involves a unique process: (a) picking tobacco leaves, (b) curing tobacco leaves, (c) removing stems of tobacco leaves, cutting leaves and putting on a bamboo rack, (d) drying in the sun, reversing a rack, spraying a tobacco extract to adjust the tobacco's color, storing dried tobacco and packaging. These processes may lead to adverse health effects caused by dermal absorption of nicotine such as Green Tobacco Sickness (GTS). The aim of this study was to determine the correlation between GTS resulting from dry Thai traditional tobacco production and salivary cotinine levels among Thai traditional tobacco farmers in Nan Province, Thailand. A prospective cohort study was conducted with 20 tobacco farmers and 20 non-tobacco farmers in Praputtabath Sub-District and Phatow Sub-District. The participants were randomly selected and interviewed using in person questionnaires with bi-weekly follow-up for 14 weeks. During each contact, the cotinine concentration was measured by NicAlert(TM) Saliva strip tests (NCTS). Descriptive statistics and Spearman's correlation (Spearman's rho) was used to examine the relationship between the variables at both 0.01 and 0.05 significant probability levels. This study indicated that GTS from dry tobacco production has the potential to be considered a common occupational disease. This study demonstrated the usefulness of salivary cotinine level measurements by NCTS. The levels were well correlated with farmers who were employed in the dry Thai tobacco production industry. Salivary cotinine levels were also significantly correlated with the prevalence of GTS in the group of tobacco farmers at any given time within a crop season. However, the production process of dry Thai traditional tobacco is different from that evaluated in our previous studies where GTS and salivary cotinine level were correlated in workers working in humid conditions. The long-term effects of such exposure

Tobacco use and addiction most often begin during youth and young adulthood. Youth use of tobacco in any form is unsafe. To determine the prevalence and trends of current (past 30-day) use of nine tobacco products (cigarettes, cigars, smokeless tobacco, e-cigarettes, hookahs, tobacco pipes, snus, dissolvable tobacco, and bidis) among U.S. middle (grades 6-8) and high school (grades 9-12) students, CDC and the Food and Drug Administration (FDA) analyzed data from the 2011-2014 National Youth Tobacco Surveys (NYTS). In 2014, e-cigarettes were the most commonly used tobacco product among middle (3.9%) and high (13.4%) school students. Between 2011 and 2014, statistically significant increases were observed among these students for current use of both e-cigarettes and hookahs (pstudents continue to be exposed to harmful tobacco product constituents, including nicotine. Nicotine exposure during adolescence, a critical window for brain development, might have lasting adverse consequences for brain development, causes addiction, and might lead to sustained tobacco use. For this reason, comprehensive and sustained strategies are needed to prevent and reduce the use of all tobacco products among youths in the United States.

To note the frequency of discussions and disputes about tobacco control measures at the World Trade Organization (WTO) before and after the coming into force of the Framework Convention on Tobacco Control (FCTC). To review trends or patterns in the positions taken by members of the WTO with respect to tobacco control measures. To discuss possible explanations for these observed trends/patterns. We gathered data on tobacco-related disputes in the WTO since its establishment in 1995 and its forerunner, the General Agreement on Tariffs and Trade (GATT), prior-FCTC and post-FCTC. We also looked at debates on tobacco control measures within the WTO more broadly. To this end, we classified and coded the positions of WTO member states during discussions on tobacco control and the FCTC, from 1995 until 2013, within the Technical Barriers to Trade (TBT) Committee and the Trade-Related Aspects of Intellectual Property Rights (TRIPS) Council. There is a growing interest within the WTO for tobacco-related issues and opposition to tobacco control measures is moving away from high-income countries towards low(er) income countries. The growing prominence of tobacco issues in the WTO can be attributed at least in part to the fact that during the past decade tobacco firms have been marginalised from the domestic policy-making process in many countries, which has forced them to look for other ways and forums to influence decision-making. Furthermore, the finding that almost all recent opposition within the WTO to stronger tobacco regulations came from developing countries is consistent with a relative shift of transnational tobacco companies' lobbying efforts from developed to developing countries.

Point-of-purchase tobacco environments and variation by store type--United States, 1999.

Science.gov (United States)

2002-03-08

To promote its products, the tobacco industry spent $8.2 billion on marketing in 1999, an increase of $1.5 billion over the previous year. Tobacco advertising in various media increases tobacco consumption and adolescents are more susceptible than adults to being influenced by some forms of tobacco advertising. To describe the retail tobacco advertising and marketing environment, researchers from the Robert Wood Johnson Foundation-sponsored ImpacTeen Project collected and analyzed store observation data in 163 communities throughout the United States. This report summarizes the extent of point-of-purchase (POP) tobacco advertising and marketing found in various types of stores. The findings in this report indicate that certain retail environments frequented by teenagers heavily promote tobacco use. To reduce demand for tobacco products among adolescents, public health efforts should address POP environment exposure to tobacco advertising and marketing.

Youth tobacco use in the United States--problem, progress, goals, and potential solutions.

Efforts to control tobacco use and tobacco-related morbidity and mortality in the United States continue to be generally successful. In the quarter century since the publication of the first Surgeon General's Report on Tobacco and Health, adult smoking rates in the United States have been reduced by nearly 34%. Controlling tobacco use among our nation's youth, however, has not been as successful. Although there was considerable success in reducing adolescent tobacco use in the late 1970s and early 1980s, tobacco use among youth has remained essentially stable for the past decade. The health and economic burden of tobacco use, current knowledge about youth tobacco use, and youth-related national tobacco reduction goals for the Year 2000 are reviewed. Analysis of the research of the past two decades clearly indicates that there is no "magic bullet" in existence or in sight for the reduction of tobacco use, either among youth or among adults. This does not mean that opportunities for significant advances through, for example, pharmacological therapies or the broad application of media or policy strategies should not continue to be explored, but that for the moment no single approach appears to work best. Rather, a comprehensive approach that applies multiple prevention and cessation strategies simultaneously appears to be most effective in tobacco use control. Among youth, the combination of tobacco control strategies that may work best includes those that involve the family, primary care physicians, and other health professionals such as nurses and dentists; programs that are carried out in schools and/or through the media; and societal approaches such as access and advertising restrictions and increased taxes.

Fiscal and policy implications of selling pipe tobacco for roll-your-own cigarettes in the United States.

Science.gov (United States)

Morris, Daniel S; Tynan, Michael A

2012-01-01

The Federal excise tax was increased for tobacco products on April 1, 2009. While excise tax rates prior to the increase were the same for roll-your-own (RYO) and pipe tobacco, the tax on pipe tobacco was $21.95 per pound less than the tax on RYO tobacco after the increase. Subsequently, tobacco manufacturers began labeling loose tobacco as pipe tobacco and marketing these products to RYO consumers at a lower price. Retailers refer to these products as "dual purpose" or "dual use" pipe tobacco. Data on tobacco tax collections comes from the Alcohol and Tobacco Tax and Trade Bureau. Joinpoint software was used to identify changes in sales trends. Estimates were generated for the amount of pipe tobacco sold for RYO use and for Federal and state tax revenue lost through August 2011. Approximately 45 million pounds of pipe tobacco has been sold for RYO use from April 2009 to August 2011, lowering state and Federal revenue by over $1.3 billion. Marketing pipe tobacco as "dual purpose" and selling it for RYO use provides an opportunity to avoid paying higher cigarette prices. This blunts the public health impact excise tax increases would otherwise have on reducing tobacco use through higher prices. Selling pipe tobacco for RYO use decreases state and Federal revenue and also avoids regulations on flavored tobacco, banned descriptors, prohibitions on shipping, and reporting requirements.

The Activity and Enthalpy of Vaporization of Nicotine from Tobacco at Moderate Temperatures

Directory of Open Access Journals (Sweden)

Full Text Available The vapor pressure of nicotine has been reported for unprotonated nicotine and for nicotine-water solutions. Yet no published values exist for nicotine in any commercially relevant matrix or for protonated forms (e.g., tobacco, smoke, electronic cigarette solutions, nicotine replacement products, nicotine salts. Therefore a methodology was developed to measure nicotine activity (defined as the vapor pressure from a matrix divided by the vapor pressure of pure nicotine. The headspace concentration of nicotine was measured for pure nicotine and tobacco stored at 23, 30, and 40 °C which allowed for conversion to vapor pressure and nicotine activity and for the estimation of enthalpy of vaporization. Burley, Flue-cured, Oriental, and cigarette blends were tested. Experiments were conducted with pure nicotine initially until the storage and sampling techniques were validated by comparison with previously published values. We found that the nicotine activity from tobacco was less than 1% with Burley > Flue-cured > Oriental. At 23 °C the nicotine vapor pressure averaged by tobacco type was 0.45 mPa for Oriental tobacco, 1.8 mPa for Flue-cured, 13 mPa for Burley while pure nicotine was 2.95 Pa. In general, the nicotine activity increased as the (calculated unprotonated nicotine concentration increased. The nicotine enthalpy of vaporization from tobacco ranged from 77 kJ/mol to 92 kJ/mol with no obvious trends with regard to tobacco origin, type, stalk position or even the wide range of nicotine activity. The mean value for all tobacco types was 86.7 kJ/mol with a relative standard deviation of 6.5% indicating that this was an intrinsic property of the nicotine form in tobacco rather than the specific tobacco properties. This value was about 30 kJ/mol greater than that of pure nicotine and is similar to the energy needed to remove a proton from monoprotonated nicotine.

Informed choice and the nanny state: learning from the tobacco industry.

Hoek, Janet

2015-08-01

To examine the 'nanny state' arguments used by tobacco companies, explore the cognitive biases that impede smokers' ability to make fully informed choices, and analyse the implications for those working to limit the harmful effects of other risk products. A critical analysis of the practices engaged in by the tobacco industry, the logic on which they relied, and the extent to which their work has informed approaches used by other industries. The tobacco industry's deliberate strategy of challenging scientific evidence undermines smokers' ability to understand the harms smoking poses and questions arguments that smoking is an informed choice. Cognitive biases predispose smokers to discount risk information, particularly when this evidence is disputed and framed as uncertain. Only state intervention has held the tobacco industry to account and begun ameliorating the effects of their sustained duplicity. Evidence other industries are now adopting similar tactics, particularly use of 'nanny state' claims to oppose proportionate interventions, is concerning. Some marketing strategies have deliberately mis-informed consumers thus directly contributing to many public health problems. Far from removing free choice, government policies that restrain commercial communications and stimuli are prerequisites necessary to promote free choice.

The Henkel technical data sheet (TDS) for Stycast 2651/Catalyst 11 lists three alternate cure schedules for the material, each of which would result in a different state of reaction and different material properties. Here, a cure schedule that attains full reaction of the material is defined. The use of this cure schedule will eliminate variance in material properties due to changes in the cure state of the material, and the cure schedule will serve as the method to make material prior to characterizing properties. The following recommendation was motivated by (1) a desire to cure at a single temperature for ease of manufacture and (2) a desire to keep the cure temperature low (to minimize residual stress build-up associated with the cooldown from the cure temperature to room temperature) without excessively limiting the cure reaction due to vitrification (i.e., material glass transition temperature, T_g, exceeding cure temperature).

Youth access to tobacco.

Science.gov (United States)

Rigotti, N A

1999-01-01

To start smoking, young people need a supply of tobacco products. Reducing youth access to tobacco is a new approach to preventing tobacco use that has been a focus of federal, state, and local tobacco control efforts over the past decade. All 50 states ban tobacco sales to minors, but compliance is poor because laws are not enforced. Consequently, young people have little trouble obtaining tobacco products. Commercial sources of tobacco (stores and vending machines) are important for underage smokers, who often purchase their own cigarettes. Underage youths also obtain tobacco from noncommercial sources such as friends, relatives, older adolescents, and adults. Educating retailers about tobacco sales laws has not produced long-term improvement in their compliance. Active enforcement of tobacco sales laws changes retailer behavior, but whether this reduces young people's access to tobacco or their tobacco use is not clear. The effectiveness of new local, state, and federal actions that aim to reduce youth access to tobacco remains to be determined. Can enforcing tobacco sales laws reduce young people's access to tobacco? If so, will this prevent or delay the onset of their tobacco use? How will youths' sources of tobacco change as commercial sources are restricted? What are the social (noncommercial) sources of tobacco for minors and how can youths' access to tobacco from these sources be reduced? What is the impact of the new federal policies aimed at reducing youth access to tobacco? Do new state and local laws that ban youth possession or use of tobacco have a net positive or negative impact on youth attitudes, access to tobacco, or tobacco use? What is the relative effectiveness and cost-effectiveness of efforts to reduce the supply of tobacco compared to those that aim to reduce demand for tobacco? Will either work alone or are both necessary to achieve reductions in youth smoking?

Tobacco and the Malays: ethnicity, health and the political economy of tobacco in Malaysia.

Science.gov (United States)

Barraclough, Simon; Morrow, Martha

2017-04-01

To identify the historical nexus between Malaysia's largest and politically dominant ethnic group and the political economy of tobacco, and to consider the implications of this connection for tobacco control. Primary and secondary documentary sources in both English and Malay were analysed to illuminate key events and decisions, and the discourse of industry and government. Sources included: speeches by Malaysian political and industry actors; tobacco industry reports, press releases and websites; government documents; World Health Organization (WHO) tobacco control literature; and press reports. Malays have the highest smoking prevalence among Malaysia's major ethnic groups. The tobacco industry has consistently been promoted as furthering Malay economic development. Malays play the major role in growing and curing. Government-owned Malay development trusts have been prominent investors in tobacco corporations, which have cultivated linkages with the Malay elite. The religious element of Malay ethnicity has also been significant. All Malays are Muslim, and the National Fatwa Council has declared smoking to be haram (forbidden); however, the Government has declined to implement this ruling. Exaggerated claims for the socio-economic benefits of tobacco production, government investment and close links between tobacco corporations and sections of the Malay elite have created a conflict of interest in public policy, limited the focus on tobacco as a health policy issue among Malays and retarded tobacco control policy. More recently, ratification of the WHO Framework Convention on Tobacco Control, regional free trade policies reducing the numbers of growers, concerns about smoking from an Islamic viewpoint, and anxieties about the effects of smoking upon youth have increasingly challenged the dominant discourse that tobacco furthers Malay interests. Nevertheless, the industry remains a formidable political and economic presence in Malaysia that is likely to continue to

2014-01-01

Tobacco use, primarily in the form of cigarettes, is the leading cause of preventable morbidity and mortality in the United States (U.S.). The adverse effects of tobacco use began to be recognized in the 1940’s and new hazards of active smoking and secondhand smoke (SHS) exposure from cigarettes continue to be identified to this day. This has led to a sustained and wide-ranging array of highly effective regulatory, public health, and clinical efforts that have been informed by extensive scien...

Combustible Tobacco and Smokeless Tobacco Use Among Working Adults-United States, 2012 to 2014.

Science.gov (United States)

Syamlal, Girija; Jamal, Ahmed; Mazurek, Jacek M

2016-12-01

The aim of this study was to examine tobacco use among working adults at least 18 years of age. The 2012 to 2014 National Health Interview Survey (n = 105,779) was used to estimate prevalences for cigarette smoking, other combustible tobacco use, and smokeless tobacco use and prevalence odds ratios (PORs) for any tobacco product use among working adults at least 18 years of age, by industry and occupation. Of the estimated 144 million currently employed adults, 17% were cigarette smokers, 7.0% other noncigarette combustible tobacco users, and 3.4% smokeless tobacco users. Odds of using tobacco varied by sociodemographic characteristics and by industry and occupations. Disparities in tobacco use exist among working adults. Continued implementation of proven interventions to prevent and reduce all forms of tobacco use among U.S. workers is warranted, particularly among those workers with a higher burden of use.

Objectives. We examined the influence of tobacco control policies (tobacco control program expenditures, smoke-free air laws, youth access law compliance, and cigarette prices) on youth smoking outcomes (smoking susceptibility, past-year initiation, current smoking, and established smoking). Methods. We combined data from the 2002 to 2008 National Surveys on Drug Use and Health with state and municipality population data from the US Census Bureau to assess the associations between state tobacco control policy variables and youth smoking outcomes, focusing on youths aged 12 to 17 years. We also examined the influence of policy variables on youth access when these variables were held at 2002 levels. Results. Per capita funding for state tobacco control programs was negatively associated with all 4 smoking outcomes. Smoke-free air laws were negatively associated with all outcomes except past-year initiation, and cigarette prices were associated only with current smoking. We found no association between these outcomes and retailer compliance with youth access laws. Conclusions. Smoke-free air laws and state tobacco control programs are effective strategies for curbing youth smoking. PMID:23327252

Classification and Quality Evaluation of Tobacco Leaves Based on Image Processing and Fuzzy Comprehensive Evaluation

Science.gov (United States)

Zhang, Fan; Zhang, Xinhong

2011-01-01

Most of classification, quality evaluation or grading of the flue-cured tobacco leaves are manually operated, which relies on the judgmental experience of experts, and inevitably limited by personal, physical and environmental factors. The classification and the quality evaluation are therefore subjective and experientially based. In this paper, an automatic classification method of tobacco leaves based on the digital image processing and the fuzzy sets theory is presented. A grading system based on image processing techniques was developed for automatically inspecting and grading flue-cured tobacco leaves. This system uses machine vision for the extraction and analysis of color, size, shape and surface texture. Fuzzy comprehensive evaluation provides a high level of confidence in decision making based on the fuzzy logic. The neural network is used to estimate and forecast the membership function of the features of tobacco leaves in the fuzzy sets. The experimental results of the two-level fuzzy comprehensive evaluation (FCE) show that the accuracy rate of classification is about 94% for the trained tobacco leaves, and the accuracy rate of the non-trained tobacco leaves is about 72%. We believe that the fuzzy comprehensive evaluation is a viable way for the automatic classification and quality evaluation of the tobacco leaves. PMID:22163744

Monitoring the Cure State of Thermosetting Resins by Ultrasound.

Science.gov (United States)

Lionetto, Francesca; Maffezzoli, Alfonso

2013-09-05

The propagation of low intensity ultrasound in a curing resin, acting as a high frequency oscillatory excitation, has been recently proposed as an ultrasonic dynamic mechanical analysis (UDMA) for cure monitoring. The technique measures sound velocity and attenuation, which are very sensitive to changes in the viscoelastic characteristics of the curing resin, since the velocity is related to the resin storage modulus and density, while the attenuation is related to the energy dissipation and scattering in the curing resin. The paper reviews the results obtained by the authors' research group in the last decade by means of in-house made ultrasonic set-ups for both contact and air-coupled ultrasonic experiments. The basics of the ultrasonic wave propagation in polymers and examples of measurements of the time-evolution of ultrasonic longitudinal modulus and chemical conversion of different thermosetting resins are presented. The effect of temperature on the cure kinetics, the comparison with rheological, low frequency dynamic mechanical and calorimetric results, and the correlation between ultrasonic modulus and crosslinking density will be also discussed. The paper highlights the reliability of ultrasonic wave propagation for monitoring the physical changes taking place during curing and the potential for online monitoring during polymer and polymer matrix composite processing.

Noncigarette tobacco products are evolving rapidly, with increasing popularity in the United States. We present prevalence estimates for 12 types of tobacco products, using data from 45,971 adult and youth participants (≥12 years of age) from Wave 1 (September 2013 through December 2014) of the Population Assessment of Tobacco and Health (PATH) Study, a large, nationally representative, longitudinal study of tobacco use and health in the United States. Participants were asked about their use of cigarettes, e-cigarettes, traditional cigars, cigarillos, filtered cigars, pipe tobacco, hookah, snus pouches, other smokeless tobacco, dissolvable tobacco, bidis, and kreteks. Estimates of the prevalence of use for each product were determined according to use category (e.g., current use or use in the previous 30 days) and demographic subgroup, and the prevalence of multiple-product use was explored. More than a quarter (27.6%) of adults were current users of at least one type of tobacco product in 2013 and 2014, although the prevalence varied depending on use category. A total of 8.9% of youths had used a tobacco product in the previous 30 days; 1.6% of youths were daily users. Approximately 40% of tobacco users, adults and youths alike, used multiple tobacco products; cigarettes plus e-cigarettes was the most common combination. Young adults (18 to 24 years of age), male adults and youths, members of racial minorities, and members of sexual minorities generally had higher use of tobacco than their counterparts. During this study, 28% of U.S. adults were current users of tobacco, and 9% of youths had used tobacco in the previous 30 days. Use of multiple products was common among tobacco users. These findings will serve as baseline data to examine between-person differences and within-person changes over time in the use of tobacco products.

Transnational Tobacco Company Influence on Tax Policy During Privatization of a State Monopoly: British American Tobacco and Uzbekistan

Science.gov (United States)

Gilmore, Anna; Collin, Jeff; Townsend, Joy

2007-01-01

Objectives. The International Monetary Fund encourages privatization of state-owned tobacco industries. Privatization tends to lower cigarette prices, which encourages consumption. This could be countered with effective tax policies. We explored how investment by British American Tobacco (BAT) influenced tax policy in Uzbekistan during privatization there. Methods. We obtained internal documents from BAT and analyzed them using a hermeneutic process to create a chronology of events. Results. BAT thoroughly redesigned the tobacco taxation system in Uzbekistan. It secured (1) a reduction of approximately 50% in the excise tax on cigarettes, (2) an excise system to benefit its brands and disadvantage those of its competitors (particularly Philip Morris), and (3) a tax stamp system from which it hoped to be exempted, because this would likely facilitate its established practice of cigarette smuggling and further its competitive advantage.. Conclusions. Privatization can endanger effective tobacco excise policies. The International Monetary Fund should review its approach to privatization and differentiate the privatization of an industry whose product kills from privatization of other industries.

To identify unmet research needs of state and community tobacco control practitioners pertaining to electronic nicotine delivery systems (ENDS or e-cigarettes) that would inform policy and practice efforts at the state and community levels, and to describe ENDS-related research and dissemination activities of the National Cancer Institute-funded State and Community Tobacco Control Research Initiative. To determine specific research gaps relevant to state and community tobacco control practice, we analysed survey data collected from tobacco control programmes (TCPs) in all 50 U.S. states and the District of Columbia (N=51). Survey items covered a range of ENDS issues: direct harm to users, harm of secondhand vapour, cessation, flavours, constituents and youth access. There is no ENDS topic on which a majority of state TCP managers feel very informed. They feel least informed about harms of secondhand vapour while also reporting that this information is among the most important for their programme. A majority (N=31) of respondents indicated needs for research on the implications of ENDS products for existing policies. TCP managers report that ENDS research is highly important for practice and need research-based information to inform decision making around the inclusion of ENDS in existing tobacco control policies. For optimal relevance to state and community TCPs, research on ENDS should prioritise study of the health effects of ENDS use and secondhand exposure to ENDS vapour in the context of existing tobacco control policies.

Tobacco and the European common agricultural policy.

Science.gov (United States)

Joossens, L; Raw, M

1991-10-01

The common agricultural policy of the European Community subsidizes tobacco production to the tune of 1,300 million ecu a year (US$ 1,500 million, UK pounds 900 million). This amounts to 2,500 ecu ($3,100, pounds 1,700) per minute, and is more in one year than the total amount spent on tobacco subsidies by the US in the last 50 years. The purpose of this policy was to maintain farmers' incomes and adapt community production to demand. Demand for the dark tobaccos which dominate EC production has fallen, while demand for light flue cured tobacco like Virginia has risen. A complex system of production subsidies and quotas was intended to discourage production of the dark tobaccos, for which there is virtually no market, and lead to more Virginia production. The policy has failed. Expenditure has spiralled out of control, production of unmarketable tobacco varieties has risen enormously, and the EC is the world's largest importer of raw tobacco. As a result tobacco is being bought by the community for intervention storage and surpluses of the dark high tar varieties are being 'exported' to eastern Europe and north Africa at giveaway prices. There has been no effective monitoring or control of this policy. This paper explains how this has happened and argues that, in view of the health risks attached to tobacco, these subsidies should be abolished.

To examine the association between state-level tobacco control measures and current use estimates of both e-cigarettes and cigarettes, while accounting for socio-demographic correlates. Using the 2012-2013 and 2013-2014 National Adult Tobacco Survey (NATS), we assessed prevalence estimates of US adults' e-cigarette and cigarette current use. Four state groups were created based on the combined state-specific prevalence of both products: low cigarette/e-cigarette (n = 15), high cigarette/e-cigarette (n = 16), high cigarette/low e-cigarette (n = 11), and low cigarette/high e-cigarette) (n = 9). To evaluate the implementation of state-level tobacco control measures, Tobacco Control Index (TCI) was calculated using the State of Tobacco Control annual reports for 2012 and 2013. Multinomial logistic regression models were used to examine differences among the four groups on socio-demographic factors and TCI. Low cigarette/e-cigarette group was used as the referent group. Current use estimates of each product varied substantially by state; current e-cigarette use was highest in Oklahoma (10.3%) and lowest in Delaware (2.7%), and current cigarette use was highest in West Virginia (26.1%), and lowest in Vermont (12.6%). Compared to low cigarette/e-cigarette, all other US-state categories had significantly lower TCI scores (high cigarette/e-cigarette: adjusted Relative Risk Ratio [aRRR] = 0.61; 95% confidence interval [CI]: 0.60-0.61, high cigarette/low e-cigarette: aRRR = 0.74; 95% CI: 0.73-0.74, and low cigarette/high e-cigarette: aRRR = 0.72; 95% CI: 0.71-073). Enforcing existing tobacco control measures likely interacts with e-cigarette use despite being cigarette-focused. Continuing to monitor e-cigarette use is critical to establish baseline use and evaluate future e-cigarette specific federal and state-level tobacco regulatory actions while accounting for the existing tobacco control environment. This study investigates state-level current use estimates of e

Experimental tests on a new harvesting system for Burley tobacco

Directory of Open Access Journals (Sweden)

Salvatore Faugno

2013-09-01

Full Text Available The globalization of the tobacco production has led to a drop in competitiveness of the Italian tobacco on the world market. Burley is the main variety of tobacco cropped in Campania region of Southern Italy. Its leaves have to be sewn, in the curing phase. Aim of this work is to show the results of the implementation of a new harvest machine prototype. Basically, the machine used for Bright tobacco, totally mechanical harvested, which doesn’t need to be sewn because it requires an indirect-fire treatment into the curing furnaces. The machine was modified in order to mechanize harvesting of Burley tobacco, and tested on four cultivars of Burley tobacco under three different planting layouts. The Burley tobacco leaves can be harvested mechanically by pulling individual leaves off the stalk; leaves are then sorted and tied in bundles prior to sewing. A mechanical burley tobacco harvesting system was evaluated. This machine consists in realizing a leaves orientation system based on the different weight between the leaf blade and the stalk enhanced by an air flow. The measurements taken were harvest timing, work capacity, and quality standards of the work carried out. The results, in terms of user time, range from 6.67 h/ha to 7.80 h/ha while in terms of operational efficiency are between 88% and 89%. The average user capacity recorded for the four cultivars is equal to 0.14 ha/h, a value far from the one recorded for the same harvesting machine used for Bright tobacco (0.25 ha/h. The harvest timing capacity, range from 0.51 t/h to 0.99 t/h. The work productivity goes from 0.17 t to 0.33 t per hour of human unit respectively. The average number of detached leaves, depending on the cultivar, has been between 523 and 744. Concerning the leaf orientation, a general percentage of 73% was achieved.

Coatings were prepared from acrylate or methacrylate functionalized resins to study the effect of end group functionality on the physical properties of u.v. and electron beam cured coatings. Cure response was measured by solid state NMR and gel extraction, as expected, methacrylate resins cured much slower. Thermal Gravimetric Analysis (TGA) revealed acrylate coatings have greater thermal stability. Properties such as tensile strength and hardness showed little effect of end group functionality or curing method. The O 2 and H 2 O permeabilities of the coating were correlated with the processing conditions. (author)

The evolution of the levels of tobacco-specific N-nitrosamines (TSNA), N-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in mainstream (MS) cigarette smoke is investigated based on smoke and tobacco chemistry data of cigarette brands sold by Philip Morris International (PMI) between 2000 and 2014. A total of 315 cigarette samples representing a wide range of product and design characteristics manufactured by PMI between 2008 and 2014 were analyzed and compared to a previously published dataset of PMI brands manufactured in 2000. The data indicate that there is a substantial reduction of NNN and NNK levels in tobacco fillers and MS cigarette smoke per mg of tar and per mg of nicotine using Health Canada Intense (HCI) machine-smoking regime. This observed reduction in NNN and NNK levels in MS cigarette smoke is also supported by the downward trend observed on NNN and NNK levels in USA flue-cured Virginia and Burley tobacco lots from 2000 to 2014 crops, reflecting effectiveness of measures taken on curing and agricultural practices designed to minimize TSNA formation in tobacco.

2016-05-01

The vast majority of tobacco users began before the age of 21. Raising the tobacco sales age to 21 has the potential to reduce tobacco use initiation and progression to regular smoking. Our objective was to assess the level of public support nationally for 'Tobacco 21' initiatives in the USA. The Social Climate Survey of Tobacco Control, a cross-sectional dual-frame survey representing national probability samples of adults was administered in 2013. Respondents were asked to state their agreement level with, 'The age to buy tobacco should be raised to 21.' Of 3245 respondents, 70.5% support raising the age to buy tobacco to 21. The majority of adults in every demographic and smoking status category supported raising the tobacco sales age to 21. In multivariable analyses, support was highest among never smokers, females, African-Americans and older adults. This national study demonstrates broad public support for raising the sales age of tobacco to 21 and will help facilitate wide dissemination of initiatives to increase the legal purchase age at national, state and local levels. Increasing public awareness about the susceptibility and rapid addiction of youth to nicotine may further increase public support for raising the tobacco sale age to 21.

In an effort to reduce patient tobacco dependence and create healthier work environments, New York State (NYS) mandated 100% tobacco-free addiction treatment programs for state funded or certified facilities in 2008. We present the results of a longitudinal study examining how local implementation features shape clinician reactions to the regulation and influence post-regulation clinician behavior and strain. A cohort of 147 clinicians associated with 13 treatment organizations throughout NYS completed a survey prior to the passage of the regulation and again approximately 1 year post-regulation. Findings reveal that local implementation features of clinician participation in the planning for change, the provision of change-related information, and perceived organizational support predicted perceptions of change management fairness, which in turn predicted clinical practice behaviors to support smoking cessation, as well as psychological and behavioral strain. In contrast, self-efficacy for change was neither related to local implementation or clinician outcomes. Practical implications are discussed. PMID:22959978

Tobacco use, primarily in the form of cigarettes, is the leading cause of preventable morbidity and mortality in the United States (U.S.). The adverse effects of tobacco use began to be recognized in the 1940’s and new hazards of active smoking and secondhand smoke (SHS) exposure from cigarettes continue to be identified to this day. This has led to a sustained and wide-ranging array of highly effective regulatory, public health, and clinical efforts that have been informed by extensive scientific data, resulting in marked decreases in the use of cigarettes. Unfortunately, the dramatic recent decline in cigarette use in the U.S., has been accompanied by an upsurge in adolescent and young adult use of new, non-cigarette tobacco and nicotine-delivery products, commonly referred to as alternative tobacco products (ATPs). Commonly used ATPs include hookah, cigars, smokeless tobacco, and electronic cigarettes. While there have been a number of review articles that focus on adult ATP use, the purpose of this review is to provide an overview of what is, and is not known about emerging ATP use among U.S. adolescents on a national scale; as well as to identify research gaps in knowledge, and discuss future health and policy needs for this growing public health concern. This paper is not meant to systemically review all published survey data, but to present clear depiction of selected ATP usage in youth populations using national survey data. PMID:25323124

There are multiple factors that can affect the risk of tobacco use in adolescence. By analyzing these factors together we can disentangle the specific relevance of each of them in shaping teenagers' individual behavior. The goal of this research study is to deepen our understanding of the relationship between tobacco use in adolescence and socio-demographic and socio-emotional variables. We worked with a representative sample of 2,289 Catalan teenagers (aged 15-18) who responded to a questionnaire drawn up by the Families and Children Panel. Regression models were developed to assess the statistical associations of different mood states (sadness, nervousness and loneliness), peer-group characteristics and parenting styles, with tobacco use. The results indicate that addictive behavior is more likely when teenagers show negative mood states, controlling for socio-demographic variables and other risk factors. Among these additional factors, authoritative parenting styles reduce the risk of tobacco use, compared to authoritarian, permissive and neglectful parenting. Extensive tobacco use within the peer group is the risk factor most strongly associated with teenagers' individual behavior.

Solid-state /sup 13/C NMR study of cured resorcinol-formaldehyde resins

The curing process generally follows the pattern observed in the stage of prepolymer formation. Catalysts (NaOH, hexa, Mg(OCOCH/sub 3/)/sub 2/) that have no substantial influence on the isomeric composition of the resorcinol-formaldehyde prepolymers, do not affect the isomeric composition of the cured resins to any significant extent either. Isomeric composition of the cured resins depends mostly on the presence of water during the curing process, necessary for depolymerisation of the added paraformaldehyde. Curing in the melt leads to enhanced 2-substitution in the 1,3-dihydroxybenzene rings. In the /sup 13/C NMR spectra of cured powdered samples, the tendency of 5-methylresorcinol to form oligomers with a higher degree of 2-substitution than resorcinol is clearly apparent. Polycondensation process continues in the powdered resins after initial curing until complete consumption of all formaldehyde. Curing of phenol-formaldehyde resols proceeds through intermediate dimethylene ether formation.

Full Text Available Background: The 5As approach is a clinic-based approach and has been developed for primary health care providers who are uniquely positioned to interact with tobacco users. The 5As stands for: Ask about tobacco use at every visit, advise tobacco users to quit, assess readiness to quit, assist quit attempts through counseling and pharmacotherapy and arrange follow-up to prevent relapse. The present study explores whether auxiliary nurse midwives (ANMs adhere to the 3As from the recommended 5As model for tobacco cessation. Materials and Methods: The study was a cross-sectional study conducted among 501 ANMs in the state of Gujarat and Andhra Pradesh. Descriptive analysis and chi-square test were employed to test the differences in knowledge levels and practices of ANMs. Bivariate logistic regression was used to examine the association between each predictor variable separately and the outcome variables after adjusting for age and location. Data was analyzed using SPSS version 17 software. Results: Majority of ANMs reported that they were aware of respiratory illnesses, tuberculosis, lung and oral cancer as conditions caused due to tobacco consumption. Awareness of adverse reproductive and child health effects associated with tobacco use was very low. Only about one third of respondents informed all patients about harmful effects. Only 16% of ANMs reported having ever received any on-job training related to tobacco control. ANMs who reported receiving training in tobacco control were about two times more likely to provide information on health effects of tobacco as compared to those who reported not being trained in tobacco control in the state of Gujarat. Conclusions: A majority of ANMs ask patients about tobacco use but provide advice only to patients suffering from specific diseases. A context-specific capacity building package needs to be designed to equip ANMs in recommended 5As approach in tobacco cessation.

Cigarette smoking has declined considerably among U.S. adults over several decades (1); however, increases have occurred in the use of noncigarette tobacco products in recent years, and the use of multiple tobacco products has become common among current users of noncigarette tobacco products (2,3). Differences in tobacco use have also been observed across population subgroups, including among working adults (2,4). CDC analyzed National Health Interview Survey (NHIS) data for 2014-2016 to describe the most recent prevalence estimates of current (every day or some days) tobacco product use among working U.S. adults by industry and occupation. Among working adults, 22.1% (32.7 million) currently used any form of tobacco; 15.4% used cigarettes, 5.8% used other combustible tobacco (cigars, pipes, water pipes or hookahs, very small cigars, and bidis), 3.0% used smokeless tobacco, and 3.6% used electronic cigarettes (e-cigarettes); 4.6% (6.9 million) reported current use of two or more tobacco products. By industry, any tobacco use ranged from 11.0% among education services to 34.3% among construction workers; current use of two or more tobacco products was highest among construction workers (7.1%). By occupation, any tobacco use ranged from 9.3% among life, physical, and social science workers to 37.2% among installation, maintenance, and repair workers; current use of two or more tobacco products was highest among installation, maintenance, and repair workers (10.1%). Proven interventions to prevent and reduce tobacco product use, including current use of multiple products, among working adults are important (5,6). Workplace tobacco-control interventions have been especially effective in reducing cigarette smoking prevalence (7).

Smokefree policies (SFPs) have diffused throughout the US and worldwide. However, the development of SFPs in the difficult policy environment of tobacco-producing states and economies worldwide has not been well-explored. In 2007, Tennessee, the third largest tobacco producer in the US, enacted the Non-Smoker Protection Act (NSPA). This study utilizes the multiple streams model to provide understanding of why and how this policy was developed by triangulating interviews with key stakeholders and legislative debates with archival documents. In June 2006, the Governor unexpectedly announced support for SFP, which created a window of opportunity for policy change. The Campaign for Healthy and Responsible Tennessee, a health coalition, seized this opportunity and worked with the administration and the Tennessee Restaurant Association to negotiate a comprehensive SFP, however, a weaker bill was used by the legislative leadership to develop the NSPA. Although the Governor and the Tennessee Restaurant Association's support generated an environment for 100% SFP, health groups did not fully capitalize on this environmental change and settled for a weak policy with several exemptions. This study suggests the importance for proponents of policy change to understand changes in their environment and be willing and able to capitalize on these changes.

Methodology to predict long-term cancer survival from short-term data using Tobacco Cancer Risk and Absolute Cancer Cure models

Three parametric statistical models have been fully validated for cancer of the larynx for the prediction of long-term 15, 20 and 25 year cancer-specific survival fractions when short-term follow-up data was available for just 1-2 years after the end of treatment of the last patient. In all groups of cases the treatment period was only 5 years. Three disease stage groups were studied, T1N0, T2N0 and T3N0. The models are the Standard Lognormal (SLN) first proposed by Boag (1949 J. R. Stat. Soc. Series B 11 15-53) but only ever fully validated for cancer of the cervix, Mould and Boag (1975 Br. J. Cancer 32 529-50), and two new models which have been termed Tobacco Cancer Risk (TCR) and Absolute Cancer Cure (ACC). In each, the frequency distribution of survival times of defined groups of cancer deaths is lognormally distributed: larynx only (SLN), larynx and lung (TCR) and all cancers (ACC). All models each have three unknown parameters but it was possible to estimate a value for the lognormal parameter S a priori. By reduction to two unknown parameters the model stability has been improved. The material used to validate the methodology consisted of case histories of 965 patients, all treated during the period 1944-1968 by Dr Manuel Lederman of the Royal Marsden Hospital, London, with follow-up to 1988. This provided a follow-up range of 20- 44 years and enabled predicted long-term survival fractions to be compared with the actual survival fractions, calculated by the Kaplan and Meier (1958 J. Am. Stat. Assoc. 53 457-82) method. The TCR and ACC models are better than the SLN model and for a maximum short-term follow-up of 6 years, the 20 and 25 year survival fractions could be predicted. Therefore the numbers of follow-up years saved are respectively 14 years and 19 years. Clinical trial results using the TCR and ACC models can thus be analysed much earlier than currently possible. Absolute cure from cancer was also studied, using not only the prediction models which

State quitlines provide free telephone-based cessation services and are available in all states. However, quitlines presently reach 1% of US cigarette smokers. We assessed variations in quitline reach by race/ethnicity across 45 US states included in the National Quitline Data Warehouse, a repository on non-identifiable data reported by state quitlines. During 2011 to 2013, we analyzed 1 220 171 records from the National Quitline Data Warehouse. Annual quitline reach was defined as the proportion of cigarette smokers and smokeless tobacco users who utilized quitline services during each year, and was calculated by dividing the number of state-specific quitline registrants in each year by the number of adult cigarette smokers and smokeless tobacco users in the state. Average annual reach ranged from: 0.08% (Tennessee) to 3.42% (Hawaii) among non-Hispanic whites; 0.17% (Tennessee) to 3.85% (Delaware) among non-Hispanic blacks; 0.27% (Nevada) to 9.98% (Delaware) among non-Hispanic American Indians/Alaska Native; 0.03% (Alabama) to 2.43% (Hawaii) among non-Hispanic Asian/Pacific Islanders; and from 0.08% (Tennessee) to 3.18% (Maine) among Hispanics. Average annual reach was highest among non-Hispanic American Indians/Alaska Native in 27 states, non-Hispanic blacks in 14 states, and non-Hispanic whites in four states. Quitlines appear to be reaching minority populations; however, overall reach remains low and variations in quitline reach exist by race/ethnicity. Opportunities exist to increase the utilization of quitlines and other effective cessation treatments among racial/ethnic minority populations. Some studies have assessed quitline reach across demographic groups in individual states; however, no studies have provided multistate data about quitline reach across race/ethnic groups. Ongoing monitoring of the use of state quitlines can help guide targeted outreach to particular race/ethnic groups with the goal of increasing the overall proportion and number of

Water pipe tobacco smoking (WTS) is growing in popularity among U.S. young adults and is associated with health risks similar to those of cigarette smoking. The purpose of this study is to examine existing tobacco control policies (TCPs) in order to investigate how they engage WTS. A systematic synthesis of content and legal interactions among federal, state, and local TCP documents. Pennsylvania, which represents a politically and demographically diverse microcosm of the United States. No human subjects. Federal and state TCPs were retrieved via public legal repositories. Local policy searches were conducted via county/municipal Web sites, inclusive of 13 localities that had autonomous health departments or existing TCPs based on a National Cancer Institute report. Full-text TCPs were double coded within a grounded theory framework for health policy analysis. Emergent codes were used to compare and contrast policy texts and to examine legal interactions among TCPs. Examination of policy categories including youth access, use restrictions, and taxation revealed WTS as largely omitted from current TCPs. WTS was sometimes addressed as an "other" tobacco product under older TCPs, though ambiguities in language led to questionable enforceability. State preemptions have rolled back or prevented well-tailored reforms at the local level. Federal preemptions have likewise constrained state TCPs. Outdated, preempted, and unclear policies limit the extent to which TCPs engage WTS. Health advocates might target these aspects of TCP reform.

Restrictions on tobacco company advertising and sponsorship are effective parts of tobacco control programmes worldwide. Through Council Directive 98/43/EC, the European Community (EC) sought to end all tobacco advertising and sponsorship in EC member states by 2006. Initially proposed in 1989, the directive was adopted in 1998, and was annulled by the European Court of Justice in 2000 following a protracted lobbying campaign against the directive by a number of interested organisations including European tobacco companies. A new advertising directive was proposed in May, 2001. We reviewed online collections of tobacco industry documents from US tobacco companies made public under the US Master Settlement Agreement of 1998. Documents reviewed dated from 1978 to 1994 and came from Philip Morris, R J Reynolds, and Brown and Williamson (British American Tobacco) collections. We also obtained approximately 15,000 pages of paper records related to British American Tobacco from its documents' depository in Guildford, UK. This information was supplemented with information in the published literature and consultations with European tobacco control experts. The tobacco industry lobbied against Directive 98/43/EC at the level of EC member state governments as well as on a pan-European level. The industry sought to prevent passage of the directive within the EC legislature, to substitute industry-authored proposals in place of the original directive, and if necessary to use litigation to prevent implementation of the directive after its passage. The tobacco industry sought to delay, and eventually defeat, the EC directive on tobacco advertising and sponsorship by seeking to enlist the aid of figures at the highest levels of European politics while at times attempting to conceal the industry's role. An understanding of these proposed strategies can help European health advocates to pass and implement effective future tobacco control legislation.

In 2013, the State of Minnesota Legislature passed a tobacco tax increase that increased the combined cigarette excise and sales tax by US$1.75 (from US$1.60 to US$3.35) and increased the tax on non-cigarette tobacco products from 70% to 95% of the wholesale price. The current study explores the change in tobacco prices in retail locations and whether the tax increase was fully passed to consumers. An observational study of tobacco retail prices was performed in a sample of 61 convenience stores in Minnesota, North Dakota, South Dakota and Wisconsin. Six rounds of data were collected between May 2013 and January 2014. In each round, purchases were made at the same stores for the same four tobacco products (Camel Blue cigarettes, Marlboro Gold cigarettes, Grizzly Wintergreen moist smokeless tobacco and Copenhagen Wintergreen moist smokeless tobacco). For all studied tobacco products, prices in Minnesota increased significantly after the tax increase (Round 1-Round 6). After controlling for price changes in neighbouring states, the average price difference in Minnesota for the two cigarette brands increased by US$1.89 and US$1.81, which are both more than the US$1.75 tax increase. For moist smokeless, the average price difference increased by US$0.90 and US$0.94. Significant price changes were not observed in the comparison states. After the introduction of the minimum moist smokeless tax, a significantly higher proportion of Minnesota stores offered price promotions on smokeless tobacco. A large tobacco tax resulted in an average retail cigarette price exceeding the tax, suggesting the industry over-shifted the cigarette tax increase to consumers in Minnesota. The findings support the known public health benefit of tobacco tax increases while highlighting the need for additional information about how, or if, tobacco companies use price promotions to blunt the impact of tax increases.

To assess youth exposure to menthol versus nonmenthol cigarette advertising, we examined whether menthol cigarette promotions are more likely in neighborhoods with relatively high youth populations. We linked 2011 New York State Retail Advertising Tobacco Survey observational data with U.S. Census and American Community Survey demographic data. Multivariable models assessed the relationship between neighborhood youth population and point-of-sale cigarette promotions for three brands of cigarettes, adjusting for neighborhood demographic characteristics including race/ethnicity and poverty. Menthol cigarette point-of-sale marketing was more likely in neighborhoods with higher proportions of youth, adjusting for presence of nonmenthol brand marketing, neighborhood race/ethnicity, neighborhood poverty, and urban geography. Data from the 2011 Retail Advertising Tobacco Study linked to block level census data clearly indicate that price reduction promotions for menthol cigarettes are disproportionately targeted to youth markets in New York State.

Full Text Available BackgroundA total of 275 million tobacco users live throughout India and are in need of tobacco cessation services. However, the preparation of physicians to deliver this service at primary care health facilities remains unknown.AimsThe study aimed to examine the primary care physicians’ preparedness to deliver tobacco cessation services in two Indian states.MethodResearchers surveyed physicians working in primary care public health facilities, primarily in rural areas using a semistructured interview schedule. Physicians’ preparedness was defined in the study as those possessing knowledge of tobacco cessation methods and exhibiting a positive attitude towards the benefits of tobacco cessation counselling as well as being willing to be part of tobacco prevention or cessation program.ResultsOverall only 17% of physicians demonstrated adequate preparation to provide tobacco cessation services at primary care health facilities in both the States. The findings revealed minimal tobacco cessation training during formal medical education (21.3% and on-the-job training (18.9%. Factors, like sex and age of service provider, type of health facility, location of health facility and number of patients attended by the service provider, failed to show significance during bivariate and regression analysis. Preparedness was significantly predicted by state health system.ConclusionThe study highlights a lack of preparedness of primary care physicians to deliver tobacco cessation services. Both the curriculum in medical school and on-the-job training require an addition of a learning component on tobacco cessation. The addition of this component will enable existing primary care facilities to deliver tobacco cessation services.

To describe the presence of licensed tobacco retailers (LTRs), cigarette advertisements, price-reducing promotions, and compliance with tobacco control policies in New York State from 2004 to 2015 and to discuss implications and lessons learned from 11 years of experience conducting LTR surveys. Annual surveys of tobacco advertising from cross-sectional, stratified random samples of LTRs in New York State from 2004 to 2015 were conducted by professional data collectors. Data for 2013 were unavailable as the survey was not fielded in that year. New York State. Licensed tobacco retailers, which are stores licensed to sell tobacco in the state of New York. Between 3.6% (n = 800) and 19.7% (n = 3945) of all LTRs were sampled annually. The presence and number of cigarette advertisements and the presence of price-reducing promotions, required age-of-sale signage, and self-service tobacco displays were documented. We tested for significant differences between 2014 and 2015 and significant trends overall and by outlet type. We used logistic regression for binary outcomes and Poisson regression for count variables. The number of LTRs in New York State decreased 22.9% from 2004 (n = 25 740) to 2015 (n = 19 855). The prevalence and number of cigarette advertisements and the prevalence of cigarette price-reducing promotions decreased significantly over time. Compliance with posting required age-of-sale signs increased significantly from 2004 to 2015 and from 2014 to 2015. Compliance with the ban on self-service tobacco displays was consistently near 100%. The tobacco retail environment in New York State improved substantially from 2004 to 2015. The implications of these findings for youth and adult smoking and the associated social costs are unknown; however, decreases in pro-tobacco marketing, decreases in the number of LTRs, and improvements in compliance are likely to have positive impacts on youth and adult smoking outcomes, such as reduced initiation and increased

In 2015, an estimated 18.8 million U.S. adults were military veterans (1). Although the prevalence of tobacco-attributable conditions is high among veterans (2), there is a paucity of data on use of tobacco products, other than cigarettes, in this population. To monitor tobacco product use among veterans, CDC analyzed self-reported current (i.e., past 30-day) use of five tobacco product types (cigarettes, cigars [big cigars, cigarillos, or little cigars], roll-your-own tobacco, pipes, and smokeless tobacco [chewing tobacco, snuff, dip, or snus]) from the National Survey on Drug Use and Health (NSDUH). Overall, 29.2% of veterans reported current use of any of the assessed tobacco products. Cigarettes were the most commonly used tobacco product (21.6%), followed by cigars (6.2%), smokeless tobacco (5.2%), roll-your-own tobacco (3.0%), and pipes (1.5%); 7.0% of veterans currently used two or more tobacco products. Within subgroups of veterans, current use of any of the assessed tobacco products was higher among persons aged 18-25 years (56.8%), Hispanics (34.0%), persons with less than a high school diploma (37.9%), those with annual family income <$20,000 (44.3%), living in poverty (53.7%), reporting serious psychological distress (48.2%), and with no health insurance (60.1%). By age and sex subgroups, use of any of the assessed tobacco products was significantly higher among all veteran groups than their nonveteran counterparts, except males aged ≥50 years. Expanding the reach of evidence-based tobacco control interventions among veterans could reduce tobacco use prevalence in this population.

Nearly Half Of Small Employers Using Tobacco Surcharges Do Not Provide Tobacco Cessation Wellness Programs.

2018-03-01

The Affordable Care Act (ACA) allowed employer plans in the small-group marketplace to charge tobacco users up to 50 percent more for premiums-known as tobacco surcharges-but only if the employer offered a tobacco cessation program and the employee in question failed to participate in it. Using 2016 survey data collected by the Henry J. Kaiser Family Foundation and Health Research and Educational Trust on 278 employers eligible for Small Business Health Options Program, we examined the prevalence of tobacco surcharges and tobacco cessation programs in the small-group market under this policy and found that 16.2 percent of small employers used tobacco surcharges. Overall, 47 percent of employers used tobacco surcharges but failed to offer tobacco cessation counseling. Wellness program prevalence was lower in states that allowed tobacco surcharges, and 10.8 percent of employers in these states were noncompliant with the ACA by charging tobacco users higher premiums without offering cessation programs. Efforts should be undertaken to improve the monitoring and enforcement of ACA tobacco rating rules.

Cigarette smoking prevalence among Medicaid enrollees (25.3%) is approximately twice that of privately insured Americans (11.8%), placing Medicaid enrollees at increased risk for smoking-related disease and death (1). Medicaid spends approximately $39 billion annually on treating smoking-related diseases (2). Individual, group, and telephone counseling and seven Food and Drug Administration (FDA)-approved medications* are effective in helping tobacco users quit (3). Although state Medicaid coverage of tobacco cessation treatments improved during 2014-2015, coverage was still limited in most states (4). To monitor recent changes in state Medicaid cessation coverage for traditional (i.e., nonexpansion) Medicaid enrollees, the American Lung Association collected data on coverage of a total of nine cessation treatments: individual counseling, group counseling, and seven FDA-approved cessation medications † in state Medicaid programs during July 1, 2015-June 30, 2017. The American Lung Association also collected data on seven barriers to accessing covered treatments, such as copayments and prior authorization. As of June 30, 2017, 10 states covered all nine of these treatments for all enrollees, up from nine states as of June 30, 2015; of these 10 states, Missouri was the only state to have removed all seven barriers to accessing these cessation treatments. State Medicaid programs that cover all evidence-based cessation treatments, remove barriers to accessing these treatments, and promote covered treatments to Medicaid enrollees and health care providers would be expected to reduce smoking, smoking-related disease, and smoking-attributable federal and state health care expenditures (5-7).

Ozone damage to tobacco in Canada

1963-12-01

Tobacco weather fleck has caused significant losses of flue-cured tobacco in southern Ontario since 1955. Fleck damage was greatest near the coast of Lake Erie and decreased progressively inland. Ozone has been shown to be one of the most important incitants of the fleck response in tobacco whereas parasitic fungi, bacteria and viruses were proven not to be implicated as causes of the disorder. The inherently susceptible variety White Gold, used in all tests, was rendered more susceptible by irrigation and nitrogen deficiency. It was also more susceptible during flowering and when producing lateral shoots. The degree and duration of stomatal opening were important factors in determining the amount of injury. Concentration of ozone in the air was shown experimentally to affect the speed of fleck response as well as the severity of symptoms. Statistically significant correlations between ozone concentrations and fleck damage were obtained from field data when the response of highly susceptible tissues only was considered. The merits of several visual rating methods are compared and discussed. 22 references, 5 figures, 11 tables.

Protecting the autonomy of states to enact tobacco control measures under trade and investment agreements.

2015-06-01

Since the adoption of the WHO's WHO Framework Convention on Tobacco Control, governments have been pursuing progressively stronger and more wide-reaching tobacco control measures. In response, tobacco companies are frequently using international trade and investment agreements as tools to challenge domestic tobacco control measures. Several significant new trade and investment agreements that some fear may provide new legal avenues to the tobacco industry to challenge health measures are currently under negotiation, including the Trans-Pacific Partnership (a 12 party agreement of Asia-Pacific regional countries) and the Transatlantic Trade and Investment Partnership (an agreement between the USA and the European Union). This commentary examines different options for treaty provisions that the parties could employ in these agreements to minimise legal risks relating to tobacco control measures. It recommends that parties take a comprehensive approach, combining provisions that minimise the potential costs of litigation with provisions that increase the likelihood of a state successfully defending tobacco control measures in such litigation.

Despite advertising bans in most European Union (EU) member states, outlets for promotion of tobacco products and especially e-cigarettes still exist. This study aimed to assess the correlates of self-reported exposure to tobacco products and e-cigarettee advertising in the EU. We analysed data from wave 82.4 of the Eurobarometer survey (November-December 2014), collected through interviews in 28 EU member states (n=27 801 aged ≥15 years) and data on bans of tobacco advertising extracted from the Tobacco Control Scale (TCS, 2013). We used multilevel logistic regression to assess sociodemographic correlates of self-reported exposure to any tobacco and e-cigarette advertisements. 40% and 41.5% of the respondents reported having seen any e-cigarette and tobacco product advertisement respectively within the past year. Current smokers, males, younger respondents, those with financial difficulties, people who had tried e-cigarettes and daily internet users were more likely to report having seen an e-cigarette and a tobacco product advertisement. Respondents in countries with more comprehensive advertising bans were less likely to self-report exposure to any tobacco advertisements (OR 0.87; 95% CI 0.79 to 0.96 for one-unit increase in TCS advertising score), but not e-cigarette advertisements (OR 1.08; 95% CI 0.95 to 1.22). Ten years after ratification of the Framework Convention for Tobacco Control, self-reported exposure to tobacco and e-cigarette advertising in the EU is higher in e-cigarette and tobacco users, as well as those with internet access. The implementation of the Tobacco Products Directive may result in significant changes in e-cigarette advertising, therefore improved monitoring of advertising exposure is required in the coming years. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Full Text Available The municipalities or counties of Campoalegre and Garzón (State of Huila and Capitanejo and Enciso (State of Santander show different chemical soil characteristics when their origin is taken into account, based on their edaphogenetic environments. For the characterization of the soils from these counties, samples from 65 farms were arranged, based on the database of farmers associated with the Protabaco Company. With the soil samples taken, chemical and texture analyses were performed, codifying the results in order to analyze them, keeping in mind the ideal parameters for the tobacco crop. In the counties of Huila, the texture, pH and organic matter were found to have ideal levels, in contrast to the phosphorus, potassium, magnesium, sulfur and chloride levels which were unsuitable, but the calcium content showed levels between suitable and good. In Santander, the pH, organic matter, phosphorus, calcium, sulfur and chloride were at unsuitable levels, in contrast, the contrary occurred with the texture and potassium which were at normal levels. It is recommended, due to the difference among the chemical parameters, that a fertilization program be handled differently for the zones of Santander and Huila, bearing in mind that the chemical parameters were found to be more limited in Santander than in Huila

In the US, denormalizing tobacco use is key to tobacco control; less attention has been paid to denormalizing tobacco sales. However, some localities have placed limits on the number and type of retailers who may sell tobacco, and some retailers have abandoned tobacco sales voluntarily. Understanding community norms surrounding tobacco sales may help accelerate tobacco denormalization. We conducted 15 focus groups with customers of California, New York, and Ohio retailers who had voluntarily discontinued tobacco sales to examine normative assumptions about where cigarettes should or should not be sold, voluntary decisions to discontinue tobacco sales, and government limits on such sales. Groups in all three states generally agreed that grocery stores that sold healthy products should not sell tobacco; California groups saw pharmacies similarly, while this was a minority opinion in the other two states. Convenience stores were regarded as a natural place to sell tobacco. In each state, it was regarded as normal and commendable for some stores to want to stop selling tobacco, although few participants could imagine convenience stores doing so. Views on government's role in setting limits on tobacco sales varied, with California and New York participants generally expressing support for restrictions, and Ohio participants expressing opposition. However, even those who expressed opposition did not approve of tobacco sales in all possible venues. Banning tobacco sales entirely was not yet normative. Limiting the ubiquitous availability of tobacco sales is key to ending the tobacco epidemic. Some limits on tobacco sales appear to be normative from the perspective of community members; it may be possible to shift norms further by problematizing the ubiquitous presence of cigarettes and drawing connections to other products already subject to restrictions.

Biomedical research towards an HIV cure is advancing in the United States and elsewhere, yet little is known about perceptions of risks and benefits among potential study participants and other stakeholders. We conducted a qualitative study to explore perceived risks and benefits of investigational HIV cure research among people living with HIV (PLWHIV), biomedical HIV cure researchers, policy-makers and bioethicists. We conducted a qualitative research study using in-depth interviews with a purposive sample of PLWHIV, biomedical HIV cure researchers, policy-makers and bioethicists in 2015-2016. We analysed interview transcripts using thematic analysis anchored in grounded theory. We conducted and analyzed 36 key informant interviews. Qualitative analysis revealed four main findings. 1) Potential HIV cure study volunteers noted needing more information and education about the potential risks of HIV cure research. 2) Biomedical HIV cure researchers, policy-makers and bioethicists showed less awareness of social and financial risks of HIV cure research than PLWHIV. 3) Most respondents across the different categories of informants identified some risks that were too great to be acceptable in HIV cure research, although a subset of PLWHIV did not place an upper limit on acceptable risk. 4) PLWHIV showed a better awareness of potential psychological benefits of participating in HIV cure research than other groups of stakeholders. Our research suggests that PLWHIV have a variable understanding of the individual risks, sometimes substantial, associated with participating in biomedical HIV cure research studies. Community engagement and increased research literacy may help improve community understanding. Intensive informed consent procedures will be necessary for ethical study implementation. The current state of HIV cure research offers greater potential benefits to society than to participants. There is likely to be disagreement among regulators, researchers, clinicians

Fix Brian V

2011-12-01

Full Text Available Abstract Background On June 22, 2009, the US FDA was granted the authority to regulate tobacco products through the Family Smoking Prevention and Tobacco Control Act (FSPTCA. The intent is to improve public health through regulations on tobacco product marketing and tobacco products themselves. This manuscript reports baseline data on smokers' attitudes and beliefs on specific issues relevant to the FSPTCA. Method Between November 2009 and January 2010, a telephone survey among a nationally representative sample of n = 678 smokers in the US was performed as part of the International Tobacco Control (ITC United States Survey. Participants answered a battery of questions on their attitudes and beliefs about aspects of the FSPTCA. Results Most smokers were unaware of the new FDA tobacco regulations. Smokers indicated support for banning cigarette promotion and nearly a quarter supported requiring tobacco companies to sell cigarettes in plain packaging. Seventy two percent of smokers supported reducing nicotine levels to make cigarettes less addictive if nicotine was made easily available in non-cigarette form. Conclusion Most smokers were limited in their understanding of efforts to regulate tobacco products in general. Smokers were supportive of efforts to better inform the public about health risks, restrict advertising, and make tobacco products less addictive.

Enacting tobacco taxes by direct popular vote in the United States: lessons from 20 years of experience.

Science.gov (United States)

Lum, K L; Barnes, R L; Glantz, S A

2009-10-01

Tobacco tax increases reduce tobacco use, can provide funds for tobacco prevention and enjoy broad public support. Because of tobacco industry influence in legislatures, US public health advocates have shifted the venue for tobacco tax policymaking to direct popular vote 22 times since 1988. We combined case studies of individual state campaigns with tobacco industry documents to identify strategies related to outcome. The tobacco industry developed a voter segmentation model to determine which tobacco tax increases it could defeat. Two industry arguments arising from this model often were raised in losing campaigns-the tax increase did not dedicate enough to tobacco control and hospitals and health maintenance organisations would profit. The industry effectively influenced early voters. Success was associated with building a strong base of public support before the campaign, dedicating sufficient funds to tobacco control, avoiding proposals largely devoted to financing hospitals and other medical service providers, effectively engaging grassroots and framing the campaign with clear justifications for cigarette tax increases. Tobacco tax ballot measures commonly allocated substantial funds to medical services; tobacco companies are becoming more successful in making this use of funds an issue. Proponents' campaigns should be timed to account for the trend to voting well before election day. Ballot measures to increase tobacco taxes with a substantial fraction of the money devoted to tobacco control activities will probably fare better than ones that give priority to funding medical services.

2018-02-19

Describe the extent to which tobacco industry marketing tactics incorporated American Indian culture and traditional tobacco. A keyword search of industry documents was conducted using document archives from the Truth Tobacco Documents Library. Tobacco industry documents (n=76) were analysed for themes. Tobacco industry marketing tactics have incorporated American Indian culture and traditional tobacco since at least the 1930s, with these tactics prominently highlighted during the 1990s with Natural American Spirit cigarettes. Documents revealed the use of American Indian imagery such as traditional headdresses and other cultural symbols in product branding and the portrayal of harmful stereotypes of Native people in advertising. The historical and cultural significance of traditional tobacco was used to validate commercially available tobacco. The tobacco industry has misappropriated culture and traditional tobacco by misrepresenting American Indian traditions, values and beliefs to market and sell their products for profit. Findings underscore the need for ongoing monitoring of tobacco industry marketing tactics directed at exploiting Native culture and counter-marketing tactics that raise awareness about the distinction between commercial and traditional tobacco use. Such efforts should be embedded within a culturally sensitive framework to reduce the burden of commercial tobacco use. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

A field experiment with 15 N isotope tracing micro-plots was carried out to study the effects of basal N fertilizer application time (0 d, 15 d, 30 d before the transplanting) on the yields, market values and N uptake, utilization and distribution in different organs of flue-cured tobacco (FCT) in two ecological tobacco production areas Zhaojiashan (N 31 degree 28', E 111 degree 15', 903 m above sea level) and Laowan (N 31 degree 27', E 111 degree 14', 1 130 m above sea level)] of Xiangfan city, Hubei province. The results showed that supplying N fertilizer significantly increased the yields and market values of FCT by 13%-40% and 14%-35% for the experimental site of Zhaojiashan (lower altitude ) and Laowan (higher altitude), respectively. Compared to applying basal fertilizer at 0 d before transplanting, applying basal fertilizer at 15-30 d before transplanting increased the market values by 10%-30% (P<0.05). And early application of basal N fertilizer (30 d before transplanting) increased N accumulation by 8%-26% as compared with that of applying basal N fertilizer at 0 d or 15 d before transplanting in the two ecological areas. There was no significant effects of basal N application time on N fertilizer efficiency in lower altitude site, but increasing by 3%-6% in higher altitude site. The proportion of fertilizer N to total N in FCT decreased by 8%-32% in lower altitude, but increased by 25%-32% in higher altitude when basal N fertilizer was supplied at 30d before transplanting., These results indicated that properly earlier supplication of basal N fertilizer could improve the N fertilizer efficiency, and thus increase the yields and market values of FCT, especially in higher altitude areas with less sunshine and lower temperature.

Tobacco use remains the leading cause of preventable death in the United States. States and municipalities have instituted a variety of tobacco control measures (TCMs) to address the significant impact tobacco use has on population health. The American Lung Association annually grades state performance of tobacco control using the State of Tobacco Control grading framework. To gain an updated understanding of how recent efforts in tobacco control have impacted tobacco use across the United States, using yearly State of Tobacco Control TCM assessments. The independent TCM variables of smoke-free air score, cessation score, excise tax, and percentage of recommended funding were selected from the American Lung Association State of Tobacco Control reports. Predictors of adult smoking rates were determined by a mixed-effects model. The 50 US states and District of Columbia. Adult smoking rate in each state from 2011 to 2013. The average adult smoking rate decreased significantly from 2011 to 2013 (21.3% [SD: 3.5] to 19.3% [SD: 3.5], P = .016). All forms of TCMs varied widely in implementation levels across states. Excise taxes (β = -.812, P = .006) and smoke-free air regulations (β = -.057, P = .008) were significant, negative predictors of adult smoking. Cessation services (β = .015, P = .46) did not have a measurable effect on adult smoking. Tobacco control measures with the strongest influence on adult smoking include the state excise tax and state smoke-free air regulations. The lack of robust funding for tobacco cessation services across the majority of US states highlights an important shortfall in current tobacco control policy.

Evaluating a tobacco leaf humidification system involving nebulisation

Full Text Available A tobacco leaf humidifying system involving nebulisation was designned, implemented and evaluated; it had a system for monitoring and recording environmental conditions thereby producing an environment having more homogeneous relative humidity, ensuring better water use, better control of relative humidity and better control in managing cured tobacco leaf moisture content, thereby leading to a consequent improvement in final product quality. 55% to 75% relative humidity and 4 to 6 hour working ranges were obtained to en- sure leaf humidification reached 16% humidity on a wet basis. Two new designs are proposed for the conditioning stage regarding this conditioning chamber’s operational management, based on the results and field observations, which would allow better leaf management, thereby avoiding the risk of losses due to manipulation and over-humidification. This work strengthens research in the field of tobacco pos- tharvest technology, complementing other research projects which have been carried out in Colombia.

Term limits and the tobacco industry.

Apollonio, Dorie E; Glantz, Stanton A; Bero, Lisa A

2014-03-01

In the 1990s several American states passed term limits on legislators with the stated intention of reducing the influence of wealthy industries on career legislators. Although term limits in the United States do not have a direct relationship to public health, the tobacco industry anticipated that term limits could have indirect effects by either limiting or expanding industry influence. We detail the strategy of the tobacco industry in the wake of term limits using internal tobacco company documents and a database of campaign contributions made to legislators in term limited states between 1988 and 2002. Despite some expectations that term limits would limit tobacco industry access to state legislators, term limits appear to have had the opposite effect. Copyright © 2013 Elsevier Ltd.

2014-04-01

The aim of this study was to investigate micromechanical properties of five dual-curing resin cements after different curing modes including light curing through glass ceramic materials. Vickers hardness (VH) and indentation modulus (Y HU) of Panavia F2.0, RelyX Unicem 2 Automix, SpeedCEM, BisCem, and BeautiCem SA were measured after 1 week of storage (37 °C, 100 % humidity). The resin cements were tested following self-curing or light curing with the second-generation light-emitting diode (LED) curing unit Elipar FreeLight 2 in Standard Mode (1,545 mW/cm(2)) or with the third-generation LED curing unit VALO in High Power Mode (1,869 mW/cm(2)) or in XtraPower Mode (3,505 mW/cm(2)). Light curing was performed directly or through glass ceramic discs of 1.5 or 3 mm thickness of IPS Empress CAD or IPS e.max CAD. VH and Y HU were analysed with Kruskal-Wallis tests followed by pairwise Wilcoxon rank sum tests (α = 0.05). RelyX Unicem 2 Automix resulted in the highest VH and Y HU followed by BeautiCem SA, BisCem, SpeedCEM, and finally Panavia F2.0. Self-curing of RelyX Unicem 2 Automix and SpeedCEM lowered VH and Y HU compared to light curing whereas self-curing of Panavia F2.0, BisCem, and BeautiCem SA led to similar or significantly higher VH and Y HU compared to light curing. Generally, direct light curing resulted in similar or lower VH and Y HU compared to light curing through 1.5-mm-thick ceramic discs. Light curing through 3-mm-thick discs of IPS e.max CAD generally reduced VH and Y HU for all resin cements except SpeedCEM, which was the least affected by light curing through ceramic discs. The resin cements responded heterogeneously to changes in curing mode. The applied irradiances and light curing times adequately cured the resin cements even through 1.5-mm-thick ceramic discs. When light curing resin cements through thick glass ceramic restorations, clinicians should consider to prolong the light curing times even with LED curing units providing high

To review strategies of transnational tobacco companies (TTCs) at creating a favourable advertising environment for their products in Hungary, with special regard to efforts resulting in the liberalisation of tobacco advertising in 1997. Analysis of internal tobacco industry documents relevant to Hungary available on the World Wide Web. Transcripts of speeches of members of the Parliament during the debate of the 1997 advertising act were also reviewed. The tobacco companies not only entered the Hungarian market by early participation in the privatisation of the former state tobacco monopoly, but also imported theirsophisticated marketing experiences. Evasion and violation of rules in force, creation of new partnerships, establishment and use of front groups, finding effective ways for influencing decision makers were all parts of a well orchestrated industry effort to avoid a strict marketing regulation for tobacco products.

Curing reactions of bismaleimide resins catalyzed by triphenylphosphine. High resolution solid-state 13C NMR study

International Nuclear Information System (INIS)

Shibahara, Sumio; Enoki, Takashi; Yamamoto, Takahisa; Motoyoshiya, Jiro; Hayashi, Sadao.

1996-01-01

The curing reactions of bismaleimide resins consisted of N,N'-4,4'-diphenylmethanebismaleimide (BMI) and o,o'-diallylbisphenol-A (DABA) in the presence of triphenylphosphine (TPP) as a catalyst were investigated. DSC measurements showed that the catalytic effect of TPP on the curing reaction of BMI was more in the presence of DABA than in its absence. In order to explore this curing reaction, N-phenylmaleimide (PMI) and o-allylphenol (AP) were selected as model compounds. The products of the PMI/TPP system were oligomers and polymers of PMI, whereas the main product of the PMI/AP/TPP system was the PMI trimer which had the five-membered ring formed via the phosphonium ylide intermediate. In these model reactions, 13 C NMR was found to be useful to distinguish between trimerization and polymerization of PMI. On the basis of the results of the model reactions, the curing reactions of bismaleimide resins were investigated by high resolution solid state 13 C NMR techniques. In the BMI/TPP system, maleimides polymerize above 175degC, but the polymerization does not proceed at 120degC. On the other hand, maleimides trimerize above 120degC in the presence of DABA and TPP. The mechanism of the trimerization is briefly discussed. (author)

Tobacco--its role in the economy and the health of African countries.

Science.gov (United States)

1985-01-01

In Africa the issue of smoking and health is complicated by the fact that in many countries tobacco is grown commercially and is relied upon to bring in foreign exchange through export, of revenue for the government if sold on the home market. Consequently, in some nations the ministries of health and of agriculture are working at cross purposes. This contradiction is recognized in the report issued recently of a World Health Organization (WHO) seminar on smoking and health organized for English-speaking Member States of the WHO African Region, and held in Zambia. In opening the seminar, the prime minister of Zambia, Mr. N. Mundia, stated that governments had an obligation to educate people on the risks involved in the use of tobacco but that this could pose a moral dilemma where tobacco production made an apparently significant contribution to the economy. Additionally, he warned that developing countries are considered valuable markets by tobacco companies and stressed that if the promotion of tobacco products by such companies represented a threat "to the health of our people, we cannot let it happen." This point was endorsed by Mr. W.C. Mwambazi, the National WHO Program Coordinator who stated that smoking was on the increase in many developing countries as a result of unscrupulous marketing practices by cigarette manufacturers and that smoking was a major threat to the realization of health for all by the year 2000. Aspects of smoking and health that have special relevance for Africa are emphasized in the report. The few studies carried out in Africa tend to confirm findings from the developed world that smoking increases the risk of cancer and coronary heart disease. Not only is tobacco smoked in Africa, but it is chewed and taken as snuff, and these uses also entail a risk to health. Case studies included in the report show that transnational tobacco companies take full advantage of the present lack of legislation in most African countries on the promotion

This study assessed whether dramatic funding reductions to the Florida Tobacco Control Program (FTCP) influenced trends in recall of the Florida "truth" anti-smoking media campaign, anti-industry attitudes and non-smoking intentions among Florida teens. We used an interrupted time series technique to test for differences in the rates of change in Florida "truth" recall, anti-industry beliefs and non-smoking intentions before and after the FTCP budget cuts using the Florida Anti-tobacco Media Evaluation (FAME) survey, a repeated cross-sectional telephone survey of Florida teens. Recall of the Florida "truth" anti-smoking campaign, anti-industry attitudes, and non-smoking intentions increased dramatically between April 1998 and May 1999. Florida "truth" recall declined after FTCP budget cuts in June 1999. Anti-industry beliefs and non-smoking intentions plateaued or began to decline after the budget cuts. The launch of the national "truth" campaign in February 2000 may have offset otherwise deleterious effects of the budget cuts on anti-industry beliefs, but not smoking intentions. Reductions in tobacco control funding have immediate effects on programme exposure and cognitive precursors to smoking initiation. There is a critical need to maintain and enhance funding for state tobacco control programmes to continue nationwide progress in preventing youth from initiating cigarette smoking.

Background Despite advertising bans in most European Union (EU) member states, outlets for promotion of tobacco products and especially e-cigarettes still exist. This study aimed to assess the correlates of self-reported exposure to tobacco products and e-cigarettee advertising in the EU. Methods We analysed data from wave 82.4 of the Eurobarometer survey (November–December 2014), collected through interviews in 28 EU member states (n=27 801 aged ≥15 years) and data on bans of tobacco advertising extracted from the Tobacco Control Scale (TCS, 2013). We used multilevel logistic regression to assess sociodemographic correlates of self-reported exposure to any tobacco and e-cigarette advertisements. Results 40% and 41.5% of the respondents reported having seen any e-cigarette and tobacco product advertisement respectively within the past year. Current smokers, males, younger respondents, those with financial difficulties, people who had tried e-cigarettes and daily internet users were more likely to report having seen an e-cigarette and a tobacco product advertisement. Respondents in countries with more comprehensive advertising bans were less likely to self-report exposure to any tobacco advertisements (OR 0.87; 95% CI 0.79 to 0.96 for one-unit increase in TCS advertising score), but not e-cigarette advertisements (OR 1.08; 95% CI 0.95 to 1.22). Conclusion Ten years after ratification of the Framework Convention for Tobacco Control, self-reported exposure to tobacco and e-cigarette advertising in the EU is higher in e-cigarette and tobacco users, as well as those with internet access. The implementation of the Tobacco Products Directive may result in significant changes in e-cigarette advertising, therefore improved monitoring of advertising exposure is required in the coming years.

Introduction State Medicaid programs can cover tobacco cessation therapies for millions of low-income smokers in the United States, but use of this benefit is low and varies widely by state. This article assesses the effects of changes in Medicaid benefit policies, general tobacco policies, smoking norms, and public health programs on the use of cessation therapy among Medicaid smokers. Methods We used longitudinal panel analysis, using 2-way fixed effects models, to examine the effects of changes in state policies and characteristics on state-level use of Medicaid tobacco cessation medications from 2010 through 2014. Results Medicaid policies that require patients to obtain counseling to get medications reduced the use of cessation medications by approximately one-quarter to one-third; states that cover all types of cessation medications increased usage by approximately one-quarter to one-third. Non-Medicaid policies did not have significant effects on use levels. Conclusions States could increase efforts to quit by developing more comprehensive coverage and reducing barriers to coverage. Reductions in barriers could bolster smoking cessation rates, and the costs would be small compared with the costs of treating smoking-related diseases. Innovative initiatives to help smokers quit could improve health and reduce health care costs. PMID:27788063

Impact of tobacco control policies on adolescent smokeless tobacco and cigar use: a difference-in-differences approach

OpenAIRE

Hawkins, Summer Sherburne; Bach, Nicoline; Baum, Christopher F.

2018-01-01

Background While increasing cigarette taxes has been a major policy driver to decrease smoking, taxes on other tobacco products have received less attention. Our aims were to evaluate the impact of chewing tobacco/cigar taxes, cigarette taxes, and smoke-free legislation on adolescent male and female use of smokeless tobacco and cigars. Methods We analyzed data on 499,381 adolescents age 14-18 years from 36 US states in the Youth Risk Behavior Surveys (1999-2013) linked to state-level tobacco ...

Hispanics are the fastest growing racial/ethnic group in the United States, and smoking is the leading preventable cause of morbidity and mortality among this population. We analyzed tobacco industry documents on R. J. Reynolds' marketing strategies toward the Hispanic population using tobacco industry document archives from the Legacy Tobacco Documents Library (http://legacy.library.ucsf.edu) between February-July 2011 and April-August 2012. Our analysis revealed that by 1980 the company had developed a sophisticated surveillance system to track the market behavior of Hispanic smokers and understand their psychographics, cultural values, and attitudes. This information was translated into targeted marketing campaigns for the Winston and Camel brands. Marketing targeted toward Hispanics appealed to values and sponsored activities that could be perceived as legitimating. Greater understanding of tobacco industry marketing strategies has substantial relevance for addressing tobacco-related health disparities.

Preventing tobacco-caused cancer: a call to action.

Science.gov (United States)

Orleans, C T

1995-11-01

Nicotine addiction is the most common serious medical problem in the country. Tobacco use is responsible for 30% of cancer deaths in the United States and 90% of all lung cancer deaths. The physical addiction to nicotine explains why over 30% of Americans continue to smoke or use tobacco despite their desires and efforts to quit. The testimony summarized in this paper recommends four broad strategies for preventing tobacco-caused cancers in the United States: a) mandating and reimbursing effective treatments for nicotine addiction; b) increasing Federal and state tobacco excise taxes and earmarking a fraction of tax revenues for tobacco prevention and cessation; c) enacting other policy changes to prevent tobacco use and addiction among children, including expanded clean indoor air legislation, comprehensive youth tobacco access legislation, and the regulation of tobacco products and their advertising and promotion; and d) expanding tobacco control research and critical Federal research support. Specific recommendations are given for each broad strategy.

Tobacco commerce on the internet: a threat to comprehensive tobacco control.

Cohen, J E; Sarabia, V; Ashley, M J

2001-12-01

Although internet use continues to increase and e-commerce sales are expected to exceed US$1 trillion by the end of 2001, there have been few assessments in the literature regarding the implications of this medium for tobacco control efforts. This commentary explores the challenges that the internet may pose to the key components of a comprehensive tobacco control strategy, and pinpoints potential approaches for addressing these challenges. Four key challenges that the internet presents for tobacco control are identified: unrestricted sales to minors; cheaper cigarettes through tax avoidance and smuggling; unfettered advertising, marketing and promotion; and continued normalisation of the tobacco industry and its products. Potential strategies for addressing these challenges include international tobacco control agreements, national and state regulation, and legal remedies.

Full Text Available Purpose: Adequate polymerization is a crucial factor in obtaining optimal physical properties and a satisfying clinical performance from composite resin materials. The aim of this study was to evaluate the polymerization efficiency of dual-cure resin cement cured with two different light curing units under zirconia structures having differing thicknesses. Materials and Methods: 4 zirconia discs framework in 4 mm diameter and in 0.5 mm, 1 mm and 1.5 mm thickness were prepared using computer-aided design system. One of the 0.5 mm-thick substructures was left as mono-layered whereas others were layered with feldspathic porcelain of same thickness and ceramic samples with 4 different thicknesses (0.5, 1, 1.5 and 2.0 mm were prepared. For each group (n=12 resin cement was light cured in polytetrafluoroethylene molds using Light Emitting Diode (LED or Quartz-Tungsten Halogen (QHT light curing units under each of 4 zirconia based discs (n=96. The values of depth of cure (in mm and the Vickers Hardness Number values (VHN were evaluated for each specimen. Results: The use of LED curing unit produced a greater depth of cure compared to QTH under ceramic discs with 0.5 and 1 mm thickness (p<0.05.At 100μm and 300 μm depth, the LED unit produced significantly greater VHN values compared to the QTH unit (p<0.05. At 500 μm depth, the difference between the VHN values of LED and QTH groups were not statistically significant. Conclusion: Light curing may not result in adequate resin cement polymerization under thick zirconia structures. LED light sources should be preferred over QTH for curing dual-cure resin cements, especially for those under thicker zirconia restorations.

A simple method was developed and validated for the simultaneous determination of metalaxyl, cyazofamid and the cyazofamid metabolite 4-chloro-5-p-tolylimidazole-2-carbonitrile (CCIM) by liquid chromatography with tandem mass spectrometry. The three target compounds were extracted from tobacco and soil with acetonitrile containing 0.1% acetic acid, and the extracts were purified using octadecylsilane. The proposed method showed satisfactory linearity (R 2 ≥ 0.9985) for the target compounds. The limits of detection for metalaxyl, cyazofamid and CCIM were 0.006, 0.06 and 0.06 mg/kg in soil and green tobacco leaves and 0.03, 0.3 and 0.3 mg/kg in cured tobacco leaves, respectively. The limits of quantification for metalaxyl, cyazofamid and CCIM were 0.02, 0.2 and 0.2 mg/kg in soil and green tobacco leaves and 0.1, 1 and 1 mg/kg in cured tobacco leaves, respectively. The average recoveries from soil and tobacco were 72.91-98.40% for metalaxyl, 76.73-105.80% for cyazofamid and 74.48-106.45% for CCIM. The relative standard deviation range was 1.23-6.99%. The developed method was successfully applied to analysis of residues of metalaxyl, cyazofamid and CCIM in real soil and tobacco samples. The results indicated that the established method could meet the requirement for the analysis of trace amounts of all three analytes in soil and tobacco. Copyright © 2017 John Wiley & Sons, Ltd.

Anxiety and Tobacco

Directory of Open Access Journals (Sweden)

Cristina Mae Wood

2010-02-01

Full Text Available Tobacco use is the first preventable cause of death. This is associated not only with physical illness and a shorter life expectancy, but also with different mental disorders such as anxiety disorders. Given the low risk perception of use, this paper reports a systematic review of the scientific literature on the relationship between anxiety and tobacco from an emotional perspective, including data on smoking prevalence, factors associated with the onset and maintenance of tobacco use, as well as those factors that hamper smoking cessation and increase relapse rates. The high rates of comorbidity between tobacco use and anxiety disorders make necessary the development of new and better tobacco cessation treatments, especially designed for those smokers with high state anxiety or anxiety sensitivity, with the aim of maximizing the efficacy.

Effect of smokeless tobacco product marketing and use on population harm from tobacco use policy perspective for tobacco-risk reduction.

Science.gov (United States)

Kozlowski, Lynn T

2007-12-01

This article presents policy perspectives on the marketing of smokeless tobacco products to reduce population harm from tobacco use. Despite consensus that smokeless tobacco products as sold in the United States are less dangerous than cigarettes, there is no consensus on how to proceed. Diverse factions have different policy concerns. While the tobacco industry is exempted from U.S. Food and Drug Administration (FDA) oversight, the pharmaceutical industry whose nicotine replacement therapy (NRT) medicines compete with smokeless tobacco as noncombustible nicotine-delivery systems are regulated by the FDA. Some public health experts support smokeless tobacco use to reduce population harm from tobacco; other public health experts oppose promoting smokeless tobacco for harm reduction. Adult consumers can freely purchase currently-marketed smokeless tobacco products and even more-deadly cigarettes. Concerns with and advantages of smokeless tobacco products are discussed. In that noncombustible medicinal nicotine-delivery systems have been proven to be effective smoking-cessation aids, smokeless tobacco, as another source of psychoactive doses of nicotine, could be used similarly, in a dose-response fashion as a smoking-cessation aid (consistent with FDA principles for evaluating generic versions of drugs). Price measures should be used on tobacco products to make costs to consumers proportional to product health risks (which would make smokeless tobacco much cheaper than cigarettes), and smokeless tobacco should be encouraged as an option for smoking cessation in adult smokers, particularly for those who have failed to stop smoking using NRT or other methods.

The Philippine tobacco industry: "the strongest tobacco lobby in Asia".

To highlight revelations from internal tobacco industry documents about the conduct of the industry in the Philippines since the 1960s. Areas explored include political corruption, health, employment of consultants, resisting pack labelling, and marketing and advertising. Systematic keyword Minnesota depository website searches of tobacco industry internal documents made available through the Master Settlement Agreement. The Philippines has long suffered a reputation for political corruption where collusion between state and business was based on the exchange of political donations for favourable economic policies. The tobacco industry was able to limit the effectiveness of proposed anti-tobacco legislation. A prominent scientist publicly repudiated links between active and passive smoking and disease. The placement of health warning labels was negotiated to benefit the industry, and the commercial environment allowed it to capitalise on their marketing freedoms to the fullest potential. Women, children, youth, and the poor have been targeted. The politically laissez faire Philippines presented tobacco companies with an environment ripe for exploitation. The Philippines has seen some of the world's most extreme and controversial forms of tobacco promotion flourish. Against international standards of progress, the Philippines is among the world's slowest nations to take tobacco control seriously.

To differentiate between the different types of tobacco users and analyze the association between types of tobacco users and factors like pocket money and peer and parental influence across most of the state in India using the data obtained from Global Youth Tobacco Survey (GYTS) between 2000 and 2004. The GYTS data encompassed a representative 2-stage probability sample of students aged 13 to 15 years across 24 states and 2 union territories in India. These students were interviewed using an anonymous, self-administered questionnaire. A very strong association between users and pocket money was found in most of the states, with northeastern states having a very strong association-Sikkim, odds ratio (OR) = 8.43 (confidence interval [CI] = 6.08-11.69), and Manipur, OR = 5.58 (CI = 3.60-8.65)-after adjusting for close friend being smoker, close friend being smokeless tobacco user, parental influence, age, and gender. This study found a strong association between tobacco use by adolescents and having pocket money and close friends being tobacco users. © 2012 APJPH.

Waterpipe tobacco smoking, also known as hookah and shisha, has surged in popularity among young people in the United States. Waterpipe is also increasingly becoming the first tobacco product that young people try. Given the limited access to and limited portability of waterpipes, waterpipe smokers who become more nicotine dependent over time may be more likely to turn to cigarettes. This study examined the relationship between waterpipe tobacco smoking and susceptibility to cigarette smoking among young adults in the United States. Using data from the 2012-2013 National Adult Tobacco Survey, a nationally representative sample of US adults, we reported rates of current waterpipe smoking and susceptibility to cigarette smoking by demographic characteristics and by use of other tobacco products among survey participants aged 18 to 24 years. Multivariable logistic regression was used to examine the relationship between current waterpipe smoking and susceptibility to cigarette smoking, defined as the lack of a firm intention not to smoke soon or within the next year. Of 2,528 young adults who had never established cigarette smoking, 15.7% (n = 398) reported being waterpipe smokers (every day or some days [n = 97; 3.8%] or rarely [n = 301; 11.9%]); 44.2% (176/398) of waterpipe smokers reported being susceptible to cigarette smoking. Those who smoked waterpipe rarely were 2.3 times as susceptible to cigarette smoking as those who were not current waterpipe smokers (OR = 2.3; 95% CI, 1.6-3.4). Current waterpipe smoking is associated with susceptibility to cigarette smoking among young adults in the United States. Longitudinal studies are needed to demonstrate causality between waterpipe smoking and initiation of cigarette smoking.

The diverging trajectories of cannabis and tobacco policies in the United States: reasons and possible implications.

Science.gov (United States)

Hall, Wayne; Kozlowski, Lynn T

2018-04-01

To examine briefly the (i) rationales for two policy proposals in the United States to make it mandatory for cigarettes to contain very low levels of nicotine and to legalize cannabis for recreational use by adults; and (ii) possible lessons that participants in each policy debate may learn from each other. We briefly describe the diverging policies towards cannabis and tobacco in the United States, explain and critically analyse their rationales and discuss possible policy lessons. Advocates of cannabis legalization have argued that prohibition has been an ineffective and expensive policy that penalizes ethnic minority users unjustly of a drug that is far less harmful than alcohol. The prohibition of traditional tobacco cigarettes has been advocated as a way to eliminate cigarette smoking. These proposals embody very different attitudes towards the harms of recreational adult drug use. Advocates of nicotine prohibition demand that alternative methods of nicotine delivery must be shown to be completely safe before adults are allowed to use them. Advocates of tobacco prohibition ignore evidence that smokers may not use these products and the likelihood of expanding the illicit tobacco market. Advocates of legalizing and regulating recreational cannabis ignore the need to tax and regulate sales in order to minimize the harms of heavy use. It is not clear that the prohibition of adult use has a useful role to play in the regulation of either cannabis or tobacco. If both products remain legal, the goals of regulating tobacco and cannabis products should be to restrict youth access, promote the use of the least harmful products, provide users with evidence-based information on both absolute and differential product risks of use and use differential taxes and marketing controls to promote ways of using these products that cause the least harm to their users. © 2017 Society for the Study of Addiction.

This study examined the impact of point-of-sale (POS) tobacco marketing restrictions in Australia and Canada, in relation to the United Kingdom and the United States where there were no such restrictions during the study period (2006–10). The data came from the International Tobacco Control Four Country Survey, a prospective multi-country cohort survey of adult smokers. In jurisdictions where POS display bans were implemented, smokers’ reported exposure to tobacco marketing declined markedly. From 2006 to 2010, in Canada, the percentages noticing POS tobacco displays declined from 74.1 to 6.1% [adjusted odds ratio (OR) = 0.26, P advertising decreased from 40.3 to 14.1% (adjusted OR = 0.61, P marketing in the United States and United Kingdom remained high during this period. In parallel, there were declines in reported exposures to other forms of advertising/promotion in Canada and Australia, but again, not in the United States or United Kingdom. Impulse purchasing of cigarettes was lower in places that enacted POS display bans. These findings indicate that implementing POS tobacco display bans does result in lower exposure to tobacco marketing and less frequent impulse purchasing of cigarettes. PMID:23640986

Cure Cycle Optimization of Rapidly Cured Out-Of-Autoclave Composites

Dong, Anqi; Zhao, Yan; Zhao, Xinqing; Yu, Qiyong

2018-01-01

Out-of-autoclave prepreg typically needs a long cure cycle to guarantee good properties as the result of low processing pressure applied. It is essential to reduce the manufacturing time, achieve real cost reduction, and take full advantage of out-of-autoclave process. The focus of this paper is to reduce the cure cycle time and production cost while maintaining high laminate quality. A rapidly cured out-of-autoclave resin and relative prepreg were independently developed. To determine a suitable rapid cure procedure for the developed prepreg, the effect of heating rate, initial cure temperature, dwelling time, and post-cure time on the final laminate quality were evaluated and the factors were then optimized. As a result, a rapid cure procedure was determined. The results showed that the resin infiltration could be completed at the end of the initial cure stage and no obvious void could be seen in the laminate at this time. The laminate could achieve good internal quality using the optimized cure procedure. The mechanical test results showed that the laminates had a fiber volume fraction of 59–60% with a final glass transition temperature of 205 °C and excellent mechanical strength especially the flexural properties.

Gopala krishna sastry, K. V. S.; manoj kumar, Putturu

2018-03-01

Concrete is recognised as a versatile construction material globally. Properties of concrete depend upon, to a greater extent, the hydration of cement and microstructure of hydrated cement. Congenial atmosphere would aid the hydration of cement and hence curing of concrete becomes essential, till a major portion of the hydration process is completed. But in areas of water inadequacy and concreting works at considerable heights, curing is problematic. Self-Curing or Internal Curing technique overcomes these problems. It supplies redundant moisture, for more than sufficient hydration of cement and diminish self-desiccation. Self-Curing agents substantially help in the conservation of water in concrete, by bringing down the evaporation during the hydration of Concrete. The present study focuses on the impact of self-curing agents such as Poly Ethylene Glycol (PEG), Poly Vinyl Alcohol (PVA) and Super Absorbent Polymer (SAP) on the concrete mix of M25 grade (reference mix). The effect of these agents on strength properties of Concrete such as compressive strength, split tensile strength and flexural strength was observed on a comparative basis which revealed that PEG 4000 was the most effective among all the agents.

China: the tipping point in tobacco control.

Science.gov (United States)

Mackay, Judith

2016-12-01

Tobacco control in China, the world's largest producer and consumer of tobacco, began in the 1980s with the first national prevalence survey and a conference on tobacco held in Tianjin. Since then, there have been dozens of research papers, partial restrictions on smoking and tobacco advertising, public education campaigns, and the ratification of the World Health Organization Framework Convention on Tobacco Control, but progress has been slow. The state-owned tobacco industry remains a major obstacle to tobacco control. In the last few years, tobacco control efforts have accelerated beyond expectations. The triggering event was the publication on tobacco by the Chinese Central Party School, the ideological think tank of the Communist Party, followed by a spate of activity: directives to government officials; regulations issued by the Ministry of Education, the People's Liberation Army and the Healthy City Standards; tobacco clauses in national advertising and philanthropy laws; the creation of a Smoke-free Beijing; an increase in tobacco taxation; and a national smoke-free law currently in draft. There is a crucial need for China to build upon these recent developments, in accepting the economic research evidence of the debit of tobacco to the economy; in implementing robust, comprehensive legislation; in increasing cigarette price through taxation and, most challenging of all, to tackle the power and influence of the state tobacco monopoly over tobacco control. © The Author 2016.

Mazurek, Jacek M; Syamlal, Girija; King, Brian A; Castellan, Robert M

2014-06-06

Smokeless tobacco causes cancers of the oral cavity, esophagus, and pancreas. CDC analyzed National Health Interview Survey (NHIS) data to estimate the proportion of U.S. working adults who used smokeless tobacco in 2005 and 2010, by industry and occupation. This report describes the results of that analysis, which showed no statistically significant change in the prevalence of smokeless tobacco use among workers from 2005 (2.7%) to 2010 (3.0%). In 2010, smokeless tobacco use was highest among adults aged 25-44 years (3.9%), males (5.6%), non-Hispanic whites (4.0%), those with no more than a high school education (3.9%), and those living in the South (3.9%). By industry, the prevalence of smokeless tobacco use ranged from 1.5% in education services to 18.8% in mining industries, and by occupation from 1.3% in office and administrative support to 10.8% in construction and extraction. These findings highlight opportunities for reducing the health and economic burdens of tobacco use among U.S. workers, especially those in certain industries (e.g., mining) and occupations (e.g., construction and extraction) where use of smokeless tobacco is especially common. CDC recommends best practices for comprehensive tobacco control programs, including effective employer interventions, such as providing employee health insurance coverage for proven cessation treatments, offering easily accessible help for those who want to quit, and establishing and enforcing tobacco-free workplace policies.

2015-10-02

The 2009 Family Smoking Prevention and Tobacco Control Act prohibits "characterizing flavors" (e.g., candy, fruit, and chocolate) other than tobacco and menthol in cigarettes; however, characterizing flavors are not currently prohibited in other tobacco products. Analyses of retail sales data suggest that U.S. consumption of flavored noncigarette tobacco products, including flavored cigars and flavored e-cigarettes, has increased in recent years. There is growing concern that widely marketed varieties of new and existing flavored tobacco products might appeal to youths (2) and could be contributing to recent increases in the use of tobacco products, including e-cigarettes and hookah, among youths. CDC and the Food and Drug Administration (FDA) analyzed data from the 2014 National Youth Tobacco Survey (NYTS) to determine the prevalence of past 30 day use (current use) of flavored e-cigarette, hookah tobacco, cigar, pipe tobacco or smokeless tobacco products, and menthol cigarettes among middle and high school students, and the proportion of current tobacco product users who have used flavored products. An estimated 70.0% (3.26 million) of all current youth tobacco users had used at least one flavored tobacco product in the past 30 days. Among current users, 63.3%, (1.58 million) had used a flavored e-cigarette, 60.6%, (1.02 million) had used flavored hookah tobacco, and 63.5% (910,000) had used a flavored cigar in the past 30 days. Given the millions of current youth tobacco users, it is important for comprehensive tobacco prevention and control strategies to address all forms of tobacco use, including flavored tobacco products, among U.S. youths.

Athletes are not a typical at-risk group for smoking combustible tobacco products, because they are generally health conscious and desire to remain fit and optimize athletic performance (1). In contrast, smokeless tobacco use historically has been associated with certain sports, such as baseball (2). Athletes might be more likely to use certain tobacco products, such as smokeless tobacco, if they perceive them to be harmless (3); however, smokeless tobacco use is not safe and is associated with increased risk for pancreatic, esophageal, and oral cancers (4). Tobacco use among youth athletes is of particular concern, because most adult tobacco users first try tobacco before age 18 years (5). To examine prevalence and trends in current (≥1 day during the past 30 days) use of combustible tobacco (cigarettes, cigars) and smokeless tobacco (chewing tobacco, snuff, or dip [moist snuff]) products among athlete and nonathlete high school students, CDC analyzed data from the 2001–2013 National Youth Risk Behavior Surveys. Current use of any tobacco (combustible or smokeless tobacco) significantly declined from 33.9% in 2001 to 22.4% in 2013; however, current smokeless tobacco use significantly increased from 10.0% to 11.1% among athletes, and did not change (5.9%) among nonathletes. Furthermore, in 2013, compared with nonathletes, athletes had significantly higher odds of being current smokeless tobacco users (adjusted odds ratio [AOR] = 1.77, pcombustible tobacco users (AOR = 0.80, p<0.05). These findings suggest that opportunities exist for development of stronger tobacco control and prevention measures targeting youth athletes regarding the health risks associated with all forms of tobacco use.

2011-03-01

The tobacco industry has challenged new FDA rules restricting outdoor tobacco advertising near schools and playgrounds on First Amendment grounds, arguing that they would lead to a near complete ban on tobacco advertising in dense urban areas. To examine how the 2009 Family Smoking Prevention and Tobacco Control Act (FSPTCA) rules banning outdoor tobacco advertising near schools and playgrounds would affect tobacco retailers. GIS spatial analyses of two different states (Missouri, New York), along with more detailed analyses of two urban areas within those states (St. Louis, New York City), were conducted in 2010. The percentage of tobacco retailers falling within 350-, 500-, and 1000-foot buffer zones was then calculated. 22% of retailers in Missouri and 51% in New York fall within 1000-foot buffers around schools. In urban settings, more retailers are affected, 29% in St. Louis and 79% in New York City. Sensitivity analyses demonstrate that smaller buffers decrease the proportion of affected retailers. That is, 350-foot buffers affect only 6.7% of retailers in St. Louis and 29% in New York City. The effects of new outdoor tobacco advertising restrictions vary by location and population density. In Missouri and New York, outdoor tobacco advertising would still be permitted in many locations if such advertising was prohibited in a 1000-foot buffer zone around schools and playgrounds. Much smaller buffer zones of 350 feet may result in almost no reduction of outdoor advertising in many parts of the country. Copyright © 2011. Published by Elsevier Inc.

A rapidly growing number of U.S. employers are charging health insurance surcharges for tobacco use to their employees. Despite their potential to price-discriminate, little systematic empirical evidence of the impacts of these tobacco surcharges has been published. We attempted to assess the impact of a health insurance surcharge for tobacco use on cessation among enrollees in Georgia's State Health Benefit Plan (GSHBP). We identified a group of enrollees in GSHBP who began paying the tobacco surcharge at the program's inception in July 2005. We examined the proportion of these enrollees who certified themselves and their family members as tobacco-free and no longer paid the surcharge through April 2011, and we defined this as implied cessation. We compared this proportion to a national expected annual 2.6% cessation rate. We also compared our observation group to a comparison group to assess surcharge avoidance. By April 2011, 45% of enrollees who paid a tobacco surcharge starting in July 2005 had certified themselves as tobacco-free. This proportion exceeded the expected cessation based on 3 times the national rate (p health insurance surcharges in changing behavior, are tempered by the important limitation that enrollees' certification of quitting was self-reported and not subject to additional, clinical verification.

It is time to regulate carcinogenic tobacco-specific nitrosamines in cigarette tobacco

Science.gov (United States)

Hecht, Stephen S.

2014-01-01

The Family Smoking Prevention and Tobacco Control Act gives the Food and Drug Administration power to regulate tobacco products. This commentary calls for immediate regulation of the carcinogenic tobacco-specific nitrosamines 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and N’-nitrosonornicotine (NNN) in cigarette tobacco as a logical path to cancer prevention. NNK and NNN, powerful carcinogens in laboratory animals, have been evaluated as “carcinogenic to humans” by the International Agency for Research on Cancer. NNK and NNN are present in the tobacco of virtually all marketed cigarettes; levels in cigarette smoke are directly proportional to the amounts in tobacco. The NNK metabolite NNAL, itself a strong carcinogen, is present in the urine of smokers and non-smokers exposed to secondhand smoke. Some of the highest levels of NNK and NNN are found in U.S. products. It is well established that factors such as choice of tobacco blend, agricultural conditions, and processing methods influence levels of NNK and NNN in cigarette tobacco and cigarette smoke. Therefore, it is time to control these factors and produce cigarettes with 100 ppb or less each of NNK and NNN in tobacco, which would result in an approximate 15-20 fold reduction of these carcinogens in the mainstream smoke of popular cigarettes sold in the United States.

To investigate the epidemiologic characteristics and outcomes of exposures to electronic cigarettes (e-cigarettes), nicotine, and tobacco products among young children in the United States. A retrospective analysis of exposures associated with nicotine and tobacco products among children younger than 6 years old was conducted by using National Poison Data System data. From January 2012 through April 2015, the National Poison Data System received 29 141 calls for nicotine and tobacco product exposures among children younger than 6 years, averaging 729 child exposures per month. Cigarettes accounted for 60.1% of exposures, followed by other tobacco products (16.4%) and e-cigarettes (14.2%). The monthly number of exposures associated with e-cigarettes increased by 1492.9% during the study period. Children e-cigarettes had 5.2 times higher odds of a health care facility admission and 2.6 times higher odds of having a severe outcome than children exposed to cigarettes. One death occurred in association with a nicotine liquid exposure. The frequency of exposures to e-cigarettes and nicotine liquid among young children is increasing rapidly and severe outcomes are being reported. Swift government action is needed to regulate these products to help prevent child poisoning. Prevention strategies include public education; appropriate product storage and use away from children; warning labels; and modifications of e-cigarette devices, e-liquid, and e-liquid containers and packaging to make them less appealing and less accessible to children.

Radiation curing: Science and technology

International Nuclear Information System (INIS)

Pappas, S.P.

1992-01-01

The science and technology of radiation curing have progressed substantially within the last 20 years. Nevertheless, radiation-curable compositions typically command relatively small shares in many of their competitive markets. This situation signifies that potential advantages of radiation curing are not generally perceived to overcome their limitations. An important objective of this book is to address this issue, within the scope of the subjects offered, by providing the present state of knowledge and by identifying the directions and challenges for future studies. The first chapter introduces radiation curing. Chapter 2 offers the first systematic presentation of inorganic and organometallic photoinitiators. Chapters 3 and 4 present the analytical techniques of photocalorimetry and real-time infrared spectroscopy, respectively. Recent advances in resin technology are offered in Chapters 5 and 6, which constitute the first comprehensive accounts of (meth)acrylated silicones and vinyl ethers, respectively. Radiation-curable coatings, printing inks, and adhesives are discussed in Chapters 7-9, respectively. Chapter 10 offers a discussion on photopolymer imaging systems

Differences in tobacco/nicotine use by sexual orientation are well documented. Development of interventions requires attention to the etiology of these differences. This study examined associations among sexual orientation discrimination, cigarette smoking, any tobacco/nicotine use, and DSM-5 tobacco use disorder (TUD) in the U.S. We used data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions based on in-person interviews with a nationally representative sample of non-institutionalized U.S. adults. Approximately 8.3% of the population reported same-sex sexual attraction, 3.1% reported at least one same-sex sexual partner in the past-year, and 2.8% self-identified as lesbian, gay or bisexual. Sexual attraction, sexual behavior, and sexual identity were significantly associated with cigarette smoking, any tobacco/nicotine use, and DSM-5 TUD. Risk of all tobacco/nicotine outcomes was most pronounced for bisexual adults across all three sexual orientation dimensions. Approximately half of sexual minorities who identified as lesbian or gay and one-fourth of those who identified as bisexual reported past-year sexual orientation discrimination. Sexual minorities who experienced high levels of past-year sexual orientation discrimination had significantly greater probability of past-year cigarette smoking, any tobacco/nicotine use, and TUD relative to sexual minorities who experienced lower levels of sexual orientation discrimination or no discrimination. Sexual minorities, especially bisexual adults, are at heightened risk of cigarette smoking, any tobacco/nicotine use, and DSM-5 TUD across all three major sexual orientation dimensions. Tobacco prevention and cessation efforts should target bisexual adults and consider the role sexual orientation discrimination plays in cigarette smoking and treatment of TUD. Differences in tobacco/nicotine use by sexual orientation are well documented, but little is known about differences across all three

Polonium-210 ( 210 Po) is a natural contaminant of tobacco and its products. Due to its volatility and inherent adsorption properties, 210 Po is one of the major potential sources of human exposure through smoking. This paper reports measurements on 210 Po and 210 Pb levels in domestic as well as imported tobacco to Iran through α-spectrometry technique. The fate of 210 Po radionuclide has been also followed from tobacco farm through curing procedure in factory. The activity levels of 210 Po in Iranian domestic and imported cigarettes is found to be on the average as 38.4±0.8 mBq/g with a range of 30.3-51.3 mBq/g and 20.0±0.6 mBq/g with a range of 18.6-21.7 mBq/g, respectively. These levels are considerably higher than those reported in many other parts of the world. In the case of tobacco produced in Iranian northern province of Guilan, drying in closed compartments by fossil fuel and elevated inventories of 210 Po in soil due to over application of phosphate-rich fertilizers seems to be the main causes of these elevated activity levels.

"People over profits": retailers who voluntarily ended tobacco sales.

Tobacco retailers are key players in the ongoing tobacco epidemic. Tobacco outlet density is linked to a greater likelihood of youth and adult smoking and greater difficulty quitting. While public policy efforts to address the tobacco problem at the retail level have been limited, some retailers have voluntarily ended tobacco sales. A previous pilot study examined this phenomenon in California, a state with a strong tobacco program focused on denormalizing smoking and the tobacco industry. We sought to learn what motivated retailers in other states to end tobacco sales and how the public and media responded. We conducted interviews with owners, managers, or representatives of six grocery stores in New York and Ohio that had voluntarily ended tobacco sales since 2007. We also conducted unobtrusive observations at stores and analyzed media coverage of each retailer's decision. Grocery store owners ended tobacco sales for two reasons, alone or in combination: health or ethics-related, including a desire to send a consistent health message to employees and customers, and business-related, including declining tobacco sales or poor fit with the store's image. The decision to end sales often appeared to resolve troubling contradictions between retailers' values and selling deadly products. New York retailers attributed declining sales to high state tobacco taxes. All reported largely positive customer reactions and most received media coverage. Forty-one percent of news items were letters to the editor or editorials; most (69%) supported the decision. Voluntary decisions by retailers to abandon tobacco sales may lay the groundwork for mandatory policies and further denormalize tobacco. Our study also suggests that high tobacco taxes may have both direct and indirect effects on tobacco use. Highlighting the contradictions between being a responsible business and selling deadly products may support voluntary decisions by retailers to end tobacco sales.

Full Text Available Background: There are no safe levels of exposure to second hand smoke and smoke-free policies are effective in reducing the burden of tobacco-related diseases and death. Pharmacists, as a unique group of health professionals, might be able to play a role in the promotion of smoke-free policies. Objective: To determine the tobacco-related knowledge of community pharmacists and assess their support for smoke-free policies in Lagos state, Nigeria. Methods: A cross-sectional descriptive study design using both quantitative and qualitative methods was employed. Two hundred and twelve randomly selected community pharmacists were surveyed using a pre-tested self-administered questionnaire. In addition, one focus group discussion was conducted with ten members of the Lagos state branch of the Association of Community Pharmacists of Nigeria. Results: The quantitative survey revealed that the majority (72.1% of the respondents were aged between 20 and 40 years, predominantly male (60.8%, Yoruba (50.2% or Igbo (40.3% ethnicity and had been practicing pharmacy for ten years or less (72.2%. A majority (90.1% of respondents were aware that tobacco is harmful to health. Slightly less (75.8% were aware that second hand smoke is harmful to health. Among the listed diseases, pharmacists responded that lung (84.4% and esophageal (68.9% cancers were the most common diseases associated with tobacco use. Less than half of those surveyed associated tobacco use with heart disease (46.9%, chronic obstructive pulmonary disease (27.8%, bladder cancer (47.2%, peripheral vascular disease (35.8% and sudden death (31.1%. Only 51.9% had heard of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC. A little over half of the respondents (53.8% were aware of any law in Nigeria controlling tobacco use. The majority of respondents supported a ban on smoking in homes (83.5%, in public places (79.2%, and in restaurants, nightclubs and bars (73.6%. For

Dental visits represent an opportunity to identify and help patients quit smoking, yet dental settings remain an untapped venue for treatment of tobacco dependence. The purpose of this analysis was to assess factors that may influence patterns of tobacco-use-related practice among a national sample of dental providers. We surveyed a representative sample of general dentists practicing in the United States (N = 1,802). Multivariable analysis was used to assess correlates of adherence to tobacco use treatment guidelines and to analyze factors that influence providers' willingness to offer tobacco cessation assistance if reimbursed for this service. More than 90% of dental providers reported that they routinely ask patients about tobacco use, 76% counsel patients, and 45% routinely offer cessation assistance, defined as referring patients for cessation counseling, providing a cessation prescription, or both. Results from multivariable analysis indicated that cessation assistance was associated with having a practice with 1 or more hygienists, having a chart system that includes a tobacco use question, having received training on treating tobacco dependence, and having positive attitudes toward treating tobacco use. Providers who did not offer assistance but who reported that they would change their practice patterns if sufficiently reimbursed were more likely to be in a group practice, treat patients insured through Medicaid, and have positive attitudes toward treating tobacco dependence. Findings indicate the potential benefit of increasing training opportunities and promoting system changes to increase involvement of dental providers in conducting tobacco use treatment. Reimbursement models should be tested to assess the effect on dental provider practice patterns.

EVALUATION OF DIELECTRIC CURING MONITORING INVESTIGATING LIGHT-CURING DENTAL FILLING COMPOSITES

Directory of Open Access Journals (Sweden)

Johannes Steinhaus

2011-05-01

Full Text Available The aim of this study is the evaluation of a dielectric analysis (DEA method monitoring the curing behaviour of a light curing dental filling material in real-time. The evaluation is to extract the influence of light intensity on the photo-curing process of dental composite filling materials. The intensity change is obtained by measuring the curing process at different sample depth. It could be shown that increasing sample thickness, and therefore exponentially decreasing light intensity, causes a proportional decrease in the initial curing rate. Nevertheless, the results give rise to the assumption that lower illumination intensities over a long period cause higher overall conversion, and thus better mechanical properties. This would allow for predictions of the impact of different curing-rates on the final mechanical properties.

In 2009, the Food and Drug Administration (FDA) banned characterising flavours in cigarettes (except for menthol) due to their appeal to teen starter smokers. In August 2016, the agency deemed all tobacco products to be under its authority and a more comprehensive flavour ban is under consideration. To determine the scope and scale of alcohol-flavoured tobacco products among cigars & cigarillos, hookahs and electronic cigarettes (e-cigarettes). Alcohol-flavoured tobacco products were identified by online search of tobacco purveyors' product lines and via Google search cross-referencing the various tobacco product types versus a list of alcoholic beverage flavours (eg, wine, beer, appletini, margarita). 48 types of alcohol-flavoured tobacco products marketed by 409 tobacco brands were identified. Alcohol flavours included mixed drinks (n=25), spirits (11), liqueurs (7) and wine/beer (5). Sweet and fruity tropical mixed drink flavours were marketed by the most brands: piña colada (96), mojito (66) and margarita (50). Wine flavours were common with 104 brands. Among the tobacco product categories, brands offering alcohol-flavoured e-cigarettes (280) were most numerous, but alcohol-flavoured products were also marketed by cigars & cigarillos (88) and hookah brands (41). Brands by major tobacco companies (eg, Philip Morris, Imperial Tobacco) were well represented among alcohol-flavoured cigars & cigarillos with five companies offering a total of 17 brands. The widespread availability of alcohol-flavoured tobacco products illustrates the need to regulate characterising flavours on all tobacco products. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

India has 274 million tobacco users and a tobacco use prevalence of 38% in rural areas. Tobacco consumption causes 1 million deaths and costs the health system nearly US$23 billion annually. Tobacco control policies exist but lack proper implementation. In this article, we review the Tobacco-free Village (TfV) program conducted in Maharashtra state in India and describe its process to help villages in rural India achieve "tobacco-free" status (i.e., the sale and use of tobacco are prohibited by law). We reviewed program documents and conducted 22 qualitative interviews with program staff and village-level stakeholders. From 2008 to 2014, Salaam Mumbai Foundation implemented the TfV program in 60 villages in Maharashtra state. The program used a number of strategies to help villages become tobacco free, including collaborating with a community-based organization, leveraging existing health workers, conducting a situation analysis, training health workers, engaging stakeholders, developing TfV assessment criteria, mobilizing the community, conducting health education, imposing sanctions, and offering incentives. By 2014, 4 villages had achieved tobacco-free status according to 11 assessment criteria. Successful villages demonstrated strong local leader involvement, ownership of the program, and commitment to the cause by residents. The TfV program faced barriers including poor motivation of health workers, difficulty in changing social norms of tobacco use, and refusal of local vendors to stop tobacco sales due to financial losses. This low-cost, community-driven program holds promise for helping public health practitioners and governments implement and achieve the goals of tobacco control policies, especially in resource-scarce settings. © Chatterjee et al.

Sebastian Kneipp and the Natural Cure Movement of Germany: Between Naturalism and Modern Medicine

Directory of Open Access Journals (Sweden)

Youkyung KO

2016-12-01

Full Text Available This study discusses the historical significance of the Natural Cure Movement of Germany, centering on the Kneipp Cure, a form of hydrotherapy practiced by Father Sebastian Kneipp (1821-1897. The Kneipp Cure rested on five main tenets: hydrotherapy, exercise, nutrition, herbalism, and the balance of mind and body. This study illuminates the reception of the Kneipp Cure in the context of the trilateral relationship among the Kneipp Cure, the Natural Cure Movement in general, and modern medicine. The Natural Cure Movement was ideologically based on naturalism, criticizing industrialization and urbanization. There existed various theories and methods in it, yet they shared holism and vitalism as common factors. The Natural Cure Movement of Germany began in the early 19th century. During the late 19th century and the early 20th century, it became merged in the Lebensreformbewegung (life reform movement which campaigned for temperance, anti-tobacco, and anti-vaccination. The core of the Natural Cure Movement was to advocate the world view that nature should be respected and to recognize the natural healing powers of sunlight, air, water, etc. Among varied natural therapies, hydrotherapy spread out through the activities of some medical doctors and amateur healers such as Johann Siegmund Hahn and Vincenz Prie β nitz. Later, the supporters of hydrotherapy gathered together under the German Society of Naturopathy. Sebastian Kneipp, one of the forefathers of hydrotherapy, is distinguished from other proponents of natural therapies in two aspects. First, he did not refuse to employ vaccination and medication. Second, he sought to be recognized by the medical world through cooperating with medical doctors who supported his treatment. As a result, the Kneipp cure was able to be gradually accepted into the medical world despite the “quackery” controversy between modern medicine and the Natural Cure Movement. Nowadays, the name of Sebastian Kneipp

Light-Cured Self-Etch Adhesives Undergo Hydroxyapatite-Triggered Self-Cure

Light cure is a popular mode of curing for dental adhesives. However, it suffers from inadequate light delivery when the restoration site is less accessible, in which case a self-cure mechanism is desirable to salvage any compromised polymerization. We previously reported a novel self-cure system mediated by ethyl 4-(dimethylamino)-benzoate (4E) and hydroxyapatite (HAp). The present work aims to investigate if such self-cure phenomenon takes place in adhesives that underwent prior inadequate light cure and to elucidate if HAp released from the dental etching process is sufficient to trigger it. Model self-etch adhesives were formulated with various components, including bis[2-methacryloyloxy)ethyl]-phosphate (2MP) as acidic monomer and trimethylbenzoyl-diphenylphosphine oxide (TPO) as photoinitiator. In vitro evolution of degree of conversion (DC) of HAp-incorporated adhesives was monitored by infrared spectroscopy during light irradiation and dark storage. Selected adhesives were allowed to etch and extract HAp from enamel, light-cured in situ, and stored in the dark, after which Raman line mapping was used to obtain spatially resolved DC across the enamel-resin interface. Results showed that TPO+4E adhesives reached DC similar to TPO-only counterparts upon completion of light irradiation but underwent another round of initiation that boosted DC to ~100% regardless of HAp level or prior light exposure. When applied to enamel, TPO-only adhesives had ~80% DC in resin, which gradually descended to ~50% in enamel, whereas TPO+4E adhesives consistently scored ~80% DC across the enamel-resin interface. These observations suggest that polymerization of adhesives that underwent insufficient light cure is salvaged by the novel self-cure mechanism, and such salvaging effect can be triggered by HAp released from dental substrate during the etching process.

Mass media content may play an important role in policy change. However, the empirical relationship between media advocacy efforts and tobacco control policy success has rarely been studied. We examined the extent to which newspaper content characteristics (volume, slant, frame, source, use of evidence, and degree of localization) that have been identified as important in past descriptive studies were associated with policy progression over a 2-year period in the context of point-of-sale (POS) tobacco control. We used regression analyses to test the relationships between newspaper content and policy progression from 2012 to 2014. The dependent variable was the level of implementation of state-level POS tobacco control policies at Time 2. Independent variables were newspaper article characteristics (volume, slant, frame, source, use of evidence, and degree of localization) and were collected via content analysis of the articles. State-level policy environment contextual variables were examined as confounders. Positive, significant bivariate relationships exist between characteristics of news content (e.g., high overall volume, public health source present, local quote and local angle present, and pro-tobacco control slant present) and Time 2 POS score. However, in a multivariate model controlling for other factors, significant relationships did not hold. Newspaper coverage can be a marker of POS policy progression. Whether media can influence policy implementation remains an important question. Future work should continue to tease out and confirm the unique characteristics of media content that are most associated with subsequent policy progression, in order to inform media advocacy efforts.

SureCure{sup (R)}-A new material to reduces curing time and improve curing reproducibility of lead-acid batteries

This paper introduces a technology that considerably reduces the time to cure the positive plates of lead-acid batteries. In each of several full-scale trials at automotive and industrial battery manufacturers, the simple replacement of 1wt.% of leady oxide with finely-divided tetrabasic lead sulfate (SureCure(TM) by Hammond Group Inc.) is shown to accelerate significantly the conversion of tribasic lead sulfate (3BS) to tetrabasic lead sulfate (4BS) in the curing process while improving crystal structure and reproducibility. Shorter curing times result in reduced labour and energy costs, as well as reduced fixed (curing chambers and plant footprint) and working (plate inventory) capital investment. (author)

State value-added taxes (VAT) on tobacco products have been increased significantly in recent years in India. Evidence on how these VATs were associated with smoking is highly needed. State bidi and cigarette VAT rates were linked to Global Adult Tobacco Survey (GATS) India 2009-2010 and Tobacco Control Policy (TCP) India Survey waves 1 (2010-2011) and 2 (2012-2013), respectively. These linked data were used to analyze the associations between bidi VAT rates and bidi smoking, between cigarette VAT rates and cigarette smoking, and between the two VAT rates and dual use of bidis and cigarettes. Weighted logistic regressions were employed to examine GATS cross-sectional data, whereas Generalized Estimating Equations (GEE) were employed to examine longitudinal TCP data. We further stratified the analyses by gender. A 10% increase in cigarette VAT rates was associated with a 6.5% (p<0.001) decrease in dual use of cigarettes and bidis among adults and a 0.9% decrease (p<0.05) in cigarette smoking among males in TCP; and with a 21.6% decrease (p<0.05) in dual use among adults and a 17.2% decrease (p<0.001) in cigarette smoking among males in GATS. TCP analyses controlling for state fixed effects are less likely to be biased and indicate a cigarette price elasticity of - 0.44. As female smoking prevalence was extremely low, these associations were non-significant for females. Higher state cigarette VAT rates in India were significantly associated with lower cigarette smoking and lower dual use of cigarettes and bidis. Increasing state VAT rates may significantly reduce smoking in India. © The Author 2017. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco.

We measured how student tobacco use and psychological risk factors (intention to use and perceived ease of access to tobacco products) were associated with tobacco vendor compliance with India's Cigarettes and Other Tobacco Products Act provisions regulating the point-of-sale (POS) environment. We conducted a population-based cross-sectional survey of high school students (n=1373) and tobacco vendors (n=436) in school-adjacent communities (n=26) in Mumbai, India. We used in-class self-administered questionnaires of high school students, face-to-face interviews with tobacco vendors and compliance checks of tobacco POS environments. Logistic regression models with adjustments for clustering were used to measure associations between student tobacco use, psychological risk factors and tobacco POS compliance. Compliance with POS laws was low overall and was associated with lower risk of student current tobacco use (OR 0.48, 95% CI 0.26 to 0.91) and current smokeless tobacco use (OR 0.40, 95% CI 0.21 to 0.77), when controlling for student-level and community-level tobacco use risk factors. Compliance was not associated with student intention to use tobacco (OR 0.50; 95% CI 0.21 to 1.18) and perceived ease of access to tobacco (OR 0.73; 95% CI 0.53 to 1.00). Improving vendor compliance with tobacco POS laws may reduce student tobacco use. Future studies should test strategies to improve compliance with tobacco POS laws, particularly in low-income and middle-income country settings like urban India. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Progress in radiation grafting and curing is briefly reviewed. The two processes are shown to be mechanistically related. The parameters influencing yields are examined particularly for grafting. For ionising radiation grafting systems (EB and gamma ray) these include solvents, substrate and monomer structure, dose and dose-rate, temperature and more recently role of additives. In addition, for UV grafting, the significance of photoinitiators is discussed. Current applications of radiation grafting and curing are outlined. The recent development of photoinitiator free grafting and curing is examined as well as the potential for the new excimer laser sources. The future application of both grafting and curing is considered, especially the significance of the occurrence of concurrent grafting during cure and its relevance in environmental considerations

“People over Profits”: Retailers Who Voluntarily Ended Tobacco Sales

McDaniel, Patricia A.; Malone, Ruth E.

2014-01-01

Background Tobacco retailers are key players in the ongoing tobacco epidemic. Tobacco outlet density is linked to a greater likelihood of youth and adult smoking and greater difficulty quitting. While public policy efforts to address the tobacco problem at the retail level have been limited, some retailers have voluntarily ended tobacco sales. A previous pilot study examined this phenomenon in California, a state with a strong tobacco program focused on denormalizing smoking and the tobacco industry. We sought to learn what motivated retailers in other states to end tobacco sales and how the public and media responded. Methods We conducted interviews with owners, managers, or representatives of six grocery stores in New York and Ohio that had voluntarily ended tobacco sales since 2007. We also conducted unobtrusive observations at stores and analyzed media coverage of each retailer’s decision. Results Grocery store owners ended tobacco sales for two reasons, alone or in combination: health or ethics-related, including a desire to send a consistent health message to employees and customers, and business-related, including declining tobacco sales or poor fit with the store’s image. The decision to end sales often appeared to resolve troubling contradictions between retailers’ values and selling deadly products. New York retailers attributed declining sales to high state tobacco taxes. All reported largely positive customer reactions and most received media coverage. Forty-one percent of news items were letters to the editor or editorials; most (69%) supported the decision. Conclusion Voluntary decisions by retailers to abandon tobacco sales may lay the groundwork for mandatory policies and further denormalize tobacco. Our study also suggests that high tobacco taxes may have both direct and indirect effects on tobacco use. Highlighting the contradictions between being a responsible business and selling deadly products may support voluntary decisions by retailers

Assess the socioeconomic costs of smoking in Lebanon and understand the tobacco market and identify the winners and losers from the Lebanese tobacco trade. We take a close look at the market for tobacco and related markets to identify the main stakeholders and estimate the direct costs and benefits of tobacco. We also estimate lower bounds for the costs of tobacco, in terms of lost productivity, the cost of medical treatment, lost production due to premature death, and environmental damage. The paucity of data means our cost estimates are conservative lower bounds and we explicitly list the effects that we are unable to include. We identify the main actors in the tobacco trade: the Régie (the state-owned monopoly which regulates the tobacco trade), tobacco farmers, international tobacco companies, local distributors, retailers, consumers, and advertising firms. We identify as proximate actors the Ministries of Finance and Health, employers, and patients of smoking-related illnesses. In 2008, tobacco trade in Lebanon led to a total social cost of $326.7 million (1.1% of GDP). Low price tags on imported cigarettes not only increase smoking prevalence, but they also result in a net economic loss. Lebanese policymakers should consider the overall deficit from tobacco trade and implement the guidelines presented in the Framework Convention on Tobacco Control to at once increase government revenue and reduce government outlays, and save the labor market and the environment substantial costs.

The developing world, including countries like India, has become a major target for the tobacco industry to market its products. This study examines the influence of the marketing (advertising and promotion) of tobacco products on the use of tobacco by adults (ages 15 and over) in India. Data from Global Adult Tobacco Survey 2009-2010 was analyzed using methods for complex (clustered) sample designs. Multivariate logistic regression was employed to predict the use of different tobacco products by level of exposure to tobacco marketing using adults who have never used tobacco as the reference category. Odds ratios (ORs) were adjusted for education, gender, age, state of residence, wealth index, and place of residence (urban/rural). Adults in India were almost twice as likely to be current smokers (versus never users) when they were exposed to a moderate level of bidi or cigarette marketing. For bidis, among adults with high exposure, the OR for current use was 4.57 (95% confidence interval [CI]: 1.6, 13.0). Adults were more likely to be current users of smokeless tobacco (SLT) with even a low level of exposure to SLT marketing (OR = 1.24 [95% CI: 1.1, 1.4]). For SLT, the ORs showed an increasing trend (P for trend marketing (minimum, OR = 1.25 [1.1-1.4]; moderate, OR = 1.38 [1.1-1.8]; and high, OR = 2.73 [1.8-4.2]), with the trend highly significant (P marketing of tobacco products, which may take the form of advertising at the point of sale, sales or a discounted price, free coupons, free samples, surrogate advertisements, or any of several other modalities, increased prevalence of tobacco use among adults. An increasing level of exposure to direct and indirect advertisement and promotion is associated with an increased likelihood of tobacco use.

Colleges have implemented policies to limit tobacco use on-campus; however, the off-campus environment is often overlooked in tobacco control efforts. We assessed availability, marketing, and promotion of cigarettes, snus, and traditional smokeless tobacco (SLT) in a sample of communities surrounding 11 college campuses in North Carolina and Virginia. Between January-March of 2011, 2012 and 2013, 481 tobacco-selling retailers, including convenience stores, pharmacies and supermarkets, located near campuses were assessed. Trained observers completed annual point-of-sale assessments. The percentage of stores selling (81.4% to 58.6%; p < .0001) and advertising snus (80.1% to 53.11%; p < .0001) significantly decreased over time. Convenience stores increased promotions of cigarettes (65.4% to 72.8%; p = 0.04) and SLT (3.1% to 23.3%; p = 0.02). Off-campus environments have abundant tobacco availability and marketing. Colleges should collaborate with state and local tobacco control advocates to address tobacco promotion near campuses to potentially decrease product appeal and access among young adults.

Noncigarette tobacco products are increasingly popular. Researchers need to understand multiple tobacco product use to assess the effects of these products on population health. We estimate national prevalence and examine risk factors for multiple product use. We calculated prevalence estimates of current use patterns involving cigarettes, cigars, electronic cigarettes, hookah, smokeless tobacco, and snus using data from the 2012 RTI National Adult Tobacco Survey (N=3627), a random-digit-dial telephone survey of adults aged 18 and over. Associations between use patterns (exclusive single product and multiple products) and demographic characteristics were examined using Pearson chi-square tests and logistic regression. 32.1% of adults currently use 1 or more tobacco products; 14.9% use cigarettes exclusively, and 6.6% use one noncigarette product exclusively, 6.9% use cigarettes with another product (dual use), 1.3% use two noncigarette products, and 2.4% use three or more products (polytobacco use). Smokers who are young adult, male, never married, reside in the West, and made prior quit attempts were at risk for multiple product use. Over 10% of U.S. adults use multiple tobacco products. A better understanding of multiple product use involving combustible products, like cigars and hookah, is needed. Multiple product use may be associated with past quit attempts.

Effect of cure cycle on curing process and hardness for epoxy resin

Directory of Open Access Journals (Sweden)

2009-09-01

Full Text Available A 3-dimensional finite element model is developed to simulate and analyze the temperature and degree of cure field of epoxy casting part during cure process. The present model based on general finite element software ABAQUS is verified by literature example and experimental data. The numerical results show good agreement with literature example and measured data, and are even more accurate than the simulation of literature. After modeling successfully, the influence of temperature cure cycle ramps have on the temperature and degree of cure gradient is investigated. Moreover, the effect of non-uniform temperature and degree of cure field within epoxy casting part on hardness is demonstrated. The present model provides an accurate and novel method that allows further insight into the process of cure for epoxy resin.

Full Text Available Abstract Background To identify demographic and socio-economic factors that are associated with household expenditure on tobacco in Azerbaijan, Georgia, Kazakhstan, Kyrgyzstan, Russian Federation, and Tajikistan. Methods Secondary analysis of the data available through the World Bank Living Standards Monitoring Survey conducted in aforementioned countries in 1995–2000. The role of different variables (e.g. mean age of household members, household area of residence, household size, share of adult males, share of members with high education in determining household expenditure on tobacco (defined as tobacco expenditure share out of total monthly HH consumption was assessed by using multiple regression analysis. Results Significant differences were found between mean expenditure on tobacco between rich and poor – in absolute terms the rich spend significantly more compared with the poor. Poor households devote significantly higher shares of their monthly HH consumption for tobacco products. Shares of adult males were significantly associated with the share of household consumption devoted for tobacco. There was a significant negative association between shares of persons with tertiary education within the HH and shares of monthly household consumption devoted for tobacco products. The correlation between household expenditures on tobacco and alcohol was found to be positive, rather weak, but statistically significant. Conclusion Given the high levels of poverty and high rates of smoking in the New Independent States, these findings have important policy implications. They indicate that the impact and opportunity costs of smoking on household finances are more significant for the poor than for the rich. Any reductions in smoking prevalence within poor households could have a positive economic impact.

Talking Cure Models: A Framework of Analysis

Directory of Open Access Journals (Sweden)

Christopher Marx

2017-09-01

Full Text Available Psychotherapy is commonly described as a “talking cure,” a treatment method that operates through linguistic action and interaction. The operative specifics of therapeutic language use, however, are insufficiently understood, mainly due to a multitude of disparate approaches that advance different notions of what “talking” means and what “cure” implies in the respective context. Accordingly, a clarification of the basic theoretical structure of “talking cure models,” i.e., models that describe therapeutic processes with a focus on language use, is a desideratum of language-oriented psychotherapy research. Against this background the present paper suggests a theoretical framework of analysis which distinguishes four basic components of “talking cure models”: (1 a foundational theory (which suggests how linguistic activity can affect and transform human experience, (2 an experiential problem state (which defines the problem or pathology of the patient, (3 a curative linguistic activity (which defines linguistic activities that are supposed to effectuate a curative transformation of the experiential problem state, and (4 a change mechanism (which defines the processes and effects involved in such transformations. The purpose of the framework is to establish a terminological foundation that allows for systematically reconstructing basic properties and operative mechanisms of “talking cure models.” To demonstrate the applicability and utility of the framework, five distinct “talking cure models” which spell out the details of curative “talking” processes in terms of (1 catharsis, (2 symbolization, (3 narrative, (4 metaphor, and (5 neurocognitive inhibition are introduced and discussed in terms of the framework components. In summary, we hope that our framework will prove useful for the objective of clarifying the theoretical underpinnings of language-oriented psychotherapy research and help to establish a more

We investigates the effects of ratifying the WHO Framework Convention of Tobacco Control (FTCT), state capacity, path-dependency and tobacco industry activity on the implementation of effective health warning labels (HWL) on cigarette packs among low and middle income countries (LMIC). Using logistic regression in separate analyses for FCTC Article 11 compliant HWLs and graphic HWLs (GHWL), we found that the odds of FCTC compliance increased by a factor of 1.31 for each year after FCTC entered into force in the country (p health regulations require investments in broader state capacity. As the theory of path-dependency predicts voluntary agreements have long lasting influence on the direction of tobacco control in a country. Adopting voluntary HWL policies reduced likelihood of having FCTC compliant HWLs decades later. The fact that voluntary agreements delayed effective tobacco regulations suggests that policymakers must be careful of accepting industry efforts for voluntary agreements in other areas of public health as well, such as alcohol and junk food.

Cluster Headache Clinical Phenotypes: Tobacco Nonexposed (Never Smoker and No Parental Secondary Smoke Exposure as a Child) versus Tobacco-Exposed: Results from the United States Cluster Headache Survey.

Science.gov (United States)

Rozen, Todd D

2018-05-01

To present results from the United States Cluster Headache Survey comparing the clinical presentation of tobacco nonexposed and tobacco-exposed cluster headache patients. Cluster headache is uniquely tied to a personal history of tobacco usage/cigarette smoking and, if the individual cluster headache sufferer did not smoke, it has been shown that their parent(s) typically did and that individual had significant secondary smoke exposure as a child. The true nontobacco exposed (no personal or secondary exposure) cluster headache sufferer has never been fully studied. The United States Cluster Headache Survey consisted of 187 multiple choice questions related to cluster headache including: patient demographics, clinical headache characteristics, family history, triggers, smoking history (personal and secondary), and headache-related disability. The survey was placed on a website from October through December 2008. One thousand one hundred thirty-four individuals completed the survey. One hundred thirty-three subjects or 12% of the surveyed population had no personal smoking/tobacco use history and no secondary smoke exposure as an infant/child, thus a nontobacco exposed population. In the nonexposed population, there were 87 males and 46 females with a gender ratio of 1.9:1. Episodic cluster headache occurred in 80% of nonexposed subjects. One thousand and one survey responders or 88% were tobacco-exposed (729 males and 272 females) with a gender ratio of 2.7:1. Eighty-three percent had a personal smoking history, while only 17% just had parents who smoked with secondary smoke exposure. Eighty-five percent of smokers had double exposure with a personal smoking history and secondary exposure as a child. Nonexposed cluster headache subjects are significantly more likely to develop cluster headache at ages 40 years and younger, while the exposed sufferers are significantly more likely to develop cluster headache at 40 years of age and older. Nonexposed patients have a

The Tobacco Industry’s Abuse of Scientific Evidence and Activities to Recruit Scientists During Tobacco Litigation

Directory of Open Access Journals (Sweden)

Sungkyu Lee

2016-01-01

Full Text Available South Korea’s state health insurer, the National Health Insurance Service (NHIS, is in the process of a compensation suit against tobacco industry. The tobacco companies have habitually endeavored to ensure favorable outcomes in litigation by misusing scientific evidence or recruiting scientists to support its interests. This study analyzed strategies that tobacco companies have used during the NHIS litigation, which has been receiving world-wide attention. To understand the litigation strategies of tobacco companies, the present study reviewed the existing literature and carried out content analysis of petitions, preparatory documents, and supporting evidence submitted to the court by the NHIS and the tobacco companies during the suit. Tobacco companies misrepresented the World Health Organization (WHO report’s argument and misused scientific evidence, and removed the word “deadly” from the title of the citation. Tobacco companies submitted the research results of scientists who had worked as a consultant for the tobacco industry as evidence. Such litigation strategies employed by the tobacco companies internationally were applied similarly in Korean lawsuits. Results of tobacco litigation have a huge influence on tobacco control policies. For desirable outcomes of the suits, healthcare professionals need to pay a great deal of attention to the enormous volume of written opinions and supporting evidence that tobacco companies submit. They also need to face the fact that the companies engage in recruitment of scientists. Healthcare professionals should refuse to partner with tobacco industry, as recommended by Article 5.3 of the WHO Framework Convention on Tobacco Control.

Full Text Available Favorable attitudes towards tobacco control policies can facilitate their implementation and success. We examined attitudes toward four potential U.S. Federal tobacco regulations (banning menthol from cigarettes, reducing nicotine levels in cigarettes, banning candy and fruit flavored electronic cigarettes, and banning candy and fruit flavored little cigars and cigarillos and associations with individual and state variables. A nationally representative phone survey of 4337 adults assessed attitudes toward potential policies. Weighted logistic regression was used to assess relationships between attitudes and demographic factors, smoking behavior, beliefs about the government (knowledge, trust, and credibility, exposure to tobacco control campaigns, and state variables from the US Centers for Disease Control and Prevention (CDC State Tobacco Activities Tracking and Evaluation (STATE System. Most respondents supported three out of four policies. Respondents that were female, non-white, Latino, living below the poverty line, had less than high school education, were of older age, did not smoke, had higher trust in government, and were exposed to national tobacco control campaigns had higher odds of expressing favorable attitudes toward potential new tobacco regulations than did their counterparts. No state-level effects were found. While differences in attitudes were observed by individual demographic characteristics, behaviors, and beliefs, a majority of participants supported most of the potential new tobacco regulations surveyed.

1970-02-01

Ten fungi, Aspergillus niger, A. flavus, A. ochraceus, A. ruber, A. repens, A. amstelodami, Alternaria tenuis, Penicillium brevi-compactum, Cladosporium herbarum, and Chaetomium dolicotrichum, were isolated from moldy flue-cured tobacco and grown in various mixtures of N(2)-O(2) or CO(2)-O(2). A 1 to 5% concentration of O(2) in an N(2) atmosphere caused the greatest change in growth of the nine species, and a 10 to 20% concentration of O(2) for A. flavus. All species, except A. amstelodami and A. ruber, grew faster in air than in mixtures containing 10% O(2). High O(2) concentrations generally inhibited furrow production in the mycelial mats. In an atmosphere of 5 to 40% O(2) in the N(2) atmosphere, furrows formed in mycelial mats between 5 and 40% O(2) in the species except for A. ruber, A. repens, and A. amstelodami, which produced none in any concentration. As O(2) decreased below 20%, spore production was progressively decreased, colony color faded to white, and cleistothecia formation was suppressed. In CO(2)-O(2) mixtures radial growth of all species increased with each quantitative decrease of CO(2). All species except A. niger grew faster in air than in 10% CO(2). In contrast to N(2)-O(2) mixtures, the fungi formed furrows, sporulation and cleistothecial formation were suppressed, and colony color changed to white in higher O(2) concentrations.

Full Text Available Tobacco advertising, promotion, and sponsorship (TAPS bans are effective and are increasingly being implemented in a number of venues and countries, yet the state of TAPS in airports and their effect on airport smoking behavior is unknown. The objective of this study was to evaluate the presence of TAPS in airports across Europe and the US, and to begin to examine the relationship between TAPS and smoking behaviors in airports. We used a cross-sectional study design to observe 21 airports in Europe (11 and the US (10. Data collectors observed points of sale for tobacco products, types of products sold, advertisements and promotions, and branding or logos that appeared in the airport. Tobacco products were sold in 95% of all airports, with significantly more sales in Europe than the US. Advertisements appeared mostly in post-security areas; however, airports with advertisements in pre-security areas had significantly more smokers observed outdoors than airports without advertisements in pre-security areas. Tobacco branding appeared in designated smoking rooms as well as on non-tobacco products in duty free shops. TAPS are widespread in airports in Europe and the US and might be associated with outdoor smoking, though further research is needed to better understand any relationship between the two. This study adds to a growing body of research on tobacco control in air transit and related issues. As smoke-free policies advance, they should include comprehensive TAPS bans that extend to airport facilities.

Reinforcement of smoking and drinking: tobacco marketing strategies linked with alcohol in the United States.

Science.gov (United States)

Jiang, Nan; Ling, Pamela M

2011-10-01

We investigated tobacco companies' knowledge about concurrent use of tobacco and alcohol, their marketing strategies linking cigarettes with alcohol, and the benefits tobacco companies sought from these marketing activities. We performed systematic searches on previously secret tobacco industry documents, and we summarized the themes and contexts of relevant search results. Tobacco company research confirmed the association between tobacco use and alcohol use. Tobacco companies explored promotional strategies linking cigarettes and alcohol, such as jointly sponsoring special events with alcohol companies to lower the cost of sponsorships, increase consumer appeal, reinforce brand identity, and generate increased cigarette sales. They also pursued promotions that tied cigarette sales to alcohol purchases, and cigarette promotional events frequently featured alcohol discounts or encouraged alcohol use. Tobacco companies' numerous marketing strategies linking cigarettes with alcohol may have reinforced the use of both substances. Because using tobacco and alcohol together makes it harder to quit smoking, policies prohibiting tobacco sales and promotion in establishments where alcohol is served and sold might mitigate this effect. Smoking cessation programs should address the effect that alcohol consumption has on tobacco use.

With an increase in marijuana use among adults in the United States (US), understanding the potential impact of marijuana use on tobacco use and associated behavioral and health consequences, including respiratory conditions, is necessary. Survey responses from Wave 1 of the nationally representative Population Assessment of Tobacco and Health (PATH) Study were used to assess tobacco use and marijuana use among non-current tobacco users (n = 17,952) and current established tobacco-users classified as: cigarette only users (n = 8689), e-cigarette only users (n = 437), cigar only (traditional, cigarillo, or filtered) users (n = 706), hookah only users (n = 461), smokeless tobacco only users (n = 971), cigarette + e-cigarette users (n = 709), and users of multiple tobacco products (n = 2314). When compared to non-current tobacco users, each tobacco user group except smokeless only users had higher odds (odds ratios ranging from 3.86-8.07) of reporting current marijuana use. Among current tobacco users, higher levels of tobacco dependence did not explain the relationship between tobacco use and marijuana use. Additionally, concurrent marijuana use was associated with lower odds of attempts to quit tobacco (OR = 0.86, 95% CI = 0.79, 0.94, p users of tobacco and marijuana. Copyright © 2018 Elsevier B.V.

Jiang, Nan

Objectives. We investigated tobacco companies’ knowledge about concurrent use of tobacco and alcohol, their marketing strategies linking cigarettes with alcohol, and the benefits tobacco companies sought from these marketing activities. Methods. We performed systematic searches on previously secret tobacco industry documents, and we summarized the themes and contexts of relevant search results. Results. Tobacco company research confirmed the association between tobacco use and alcohol use. Tobacco companies explored promotional strategies linking cigarettes and alcohol, such as jointly sponsoring special events with alcohol companies to lower the cost of sponsorships, increase consumer appeal, reinforce brand identity, and generate increased cigarette sales. They also pursued promotions that tied cigarette sales to alcohol purchases, and cigarette promotional events frequently featured alcohol discounts or encouraged alcohol use. Conclusions. Tobacco companies’ numerous marketing strategies linking cigarettes with alcohol may have reinforced the use of both substances. Because using tobacco and alcohol together makes it harder to quit smoking, policies prohibiting tobacco sales and promotion in establishments where alcohol is served and sold might mitigate this effect. Smoking cessation programs should address the effect that alcohol consumption has on tobacco use. PMID:21852637

Frequency of visiting convenience and corner grocery stores that sell tobacco is positively associated with the odds of ever smoking and the risk of smoking initiation among youth. We assessed 12-year trends of tobacco availability, tobacco advertising, and ownership changes in various food stores in Albany, New York. Eligible stores were identified by multiple government lists and community canvassing in 2003 (n = 107), 2009 (n = 117), 2012 (n = 135), and 2015 (n = 137). Tobacco availability (all years) and advertising (2009, 2012, and 2015) were directly measured; electronic cigarettes (e-cigarettes) were included in 2015. Percentage of stores selling tobacco peaked at 83.8% in 2009 and declined to 74.5% in 2015 (P for trend = .11). E-cigarettes were sold by 63.7% of tobacco retailers. The largest decline in tobacco availability came from convenience stores that went out of business (n = 11), followed by pharmacies that dropped tobacco sales (n = 4). The gain of tobacco availability mostly came from new convenience stores (n = 24) and new dollar stores (n = 8). Significant declining trends (P advertising in pharmacies and in low (advertising in convenience stores and stores overall. Only one-third of stores that sold tobacco in 2003 continued to sell tobacco with the same owner in 2015. The observed subtle declines in tobacco availability and advertising were explained in part by local tobacco control efforts, the pharmacy industry's self-regulation of tobacco sales, and an increase in the state's tobacco retailer registration fee. Nonetheless, overall tobacco availability remained high (>16 retailers per 10,000 population) in this community. The high store ownership turnover rate suggests that a moratorium of new tobacco retailer registrations would be an integral part of a multi-prong policy strategy to reduce tobacco availability and advertising.

Couch, Elizabeth T; Chaffee, Benjamin W; Gansky, Stuart A; Walsh, Margaret M

2016-07-01

Tobacco products in the United States and the patterns of tobacco use are changing. Although cigarette smoking prevalence has declined, dental professionals are likely to encounter substantial numbers of patients who have tried and are continuing to use new and alternative tobacco products, including cigars, water pipes (hookahs), and electronic cigarettes, as well as conventional and new smokeless tobacco products. The authors reviewed conventional and new tobacco products in the United States, their adverse oral and systemic health effects, and their prevalence of use. Tobacco products other than cigarettes account for a substantial portion of tobacco use. For this reason, tobacco-use prevention and cessation counseling provided by dental health care professionals must address all tobacco products, including cigarettes, cigars, water pipes, and electronic cigarettes, as well as conventional and new smokeless tobacco products. Cigarette smoking and smokeless tobacco use are associated with immediate and long-term adverse health effects, including nicotine addiction, oral and systemic disease, and death. Novel products may attract new tobacco users, potentially leading to addiction that results in enduring tobacco product use and associated adverse health effects. This critical review of conventional, new, and emerging tobacco products presents information that dental professionals can use in providing tobacco-related counseling to patients who use or who are at risk for using tobacco products. It is essential that dental professionals are knowledgeable about tobacco products and are able to answer patients' questions and provide them with evidence-based tobacco-related counseling. This information may prevent patients from initiating use or help reduce or cease use to avoid immediate and long-term adverse health effects, including nicotine addiction, oral and systemic disease, and death.

Tobacco 21: An Important Public Policy to Protect Our Youth.

Science.gov (United States)

Farber, Harold J; Pakhale, Smita; Neptune, Enid R

2016-12-01

An important approach to reduce youth tobacco use is the adoption of regulations to prohibit tobacco product sale to individuals younger than 21 years, termed Tobacco 21. In the United States, close to 90% of current smokers started smoking before the age of 18 years, and 99% before age 26 years. Earlier age of tobacco use initiation is associated with lower rates of smoking cessation. Increasing minimum age to purchase has been shown to reduce tobacco product use among youth. The critical determinant is likely the loss of social sources of tobacco products. Enforcement activities are important for age-of-purchase laws to be effective. Raising the minimum legal age to purchase tobacco products to 21 years is highly supported among both the smoking and nonsmoking public. Tobacco sales to those younger than 21 years account for just 2% of total tobacco sales, yet produce 90% of new smokers. The short-term effect on small business of raising the minimum age to purchase would be minimal. Small businesses will have time to adapt to the decrease in tobacco sales as fewer youth grow up nicotine addicted. Raising the minimum age to purchase of tobacco and nicotine products to 21 years, combined with enforcement of those restrictions, will help protect future generations from a lifetime of tobacco dependence and associated morbidity. These regulations should apply to all tobacco products, including electronic nicotine delivery systems. Respiratory health care providers should educate their local, state, and federal policy makers on the importance of Tobacco 21.

The plight of tobacco farming under hegemony of transnational tobacco companies in Turkey: repercussions and remedies

Full Text Available Background The shift from State oversight to contractual farming mandated by law in 2002 as a structural adjustment conditionality has had destructive impact on Turkish tobacco agriculture: Transnational tobacco companies (TTCs gained control by being able to impose unilateral conditions; tobacco farmers were forced to face three options: prices below subsistence, migration, or turning to illicit market. A heated debate about illicit domestic tobacco market recently surfaced in news media. Methods (a Literature review, (b trend analysis of Turkish leaf tobacco output and trade as compared among 12 major tobacco growing countries, using official data (2003-2016, FAOstat (1961-2014, UNdata (1989-2015, (c review of relevant news coverage (2016 - June 2017. Results Over the last 25 years, Turkey was worst hit among the 12 countries: Leaf tobacco output dropped sharpest by 78%, and trade balance was drastically reversed. Between 2003-2016, cigarettes manufactured rose by 32.2%, leaf tobacco imports by 46.6%, whereas number of tobacco farmers declined by 82.4%, domestic output by 39.4%, and exports by 53.6%. Domestic tobacco used in cigarettes decreased from 42.1% to 13.3%. Tobacco agriculture vanished in certain regions or reduced to supplementary source of income undertaken by elderly and children. Domestic tobacco lobby seeks legalization, lower tax rates, and quotas for compulsory use of domestic tobacco in manufacturing. TTCs fervently oppose these positions and demand severe countermeasures. Conclusions TTCs ability to source leaf tobacco at lowest possible prices through their affiliates from around the world under liberalized trade and contractual farming regimes greatly harms agricultural activities realized by income and employment generating small family holdings, and thus national economies. In Turkey, TTC hegemony devastated farmers' livelihoods, caused market imbalance and duality, and disrupted regulations and taxation. Agriculture

Public policy to maximize tobacco cessation.

McGoldrick, Daniel E; Boonn, Ann V

2010-03-01

Tobacco use kills more than 400,000 Americans every year. For smokers, quitting is the biggest step they can take to improve their health, but it is a difficult step. Fortunately, policy-based interventions can both encourage smokers to quit and help them succeed. Evidence shows that tobacco tax increases encourage smokers to quit-recent state and federal increases have created dramatic surges in calls to quitlines. Similarly, smokefree workplace laws not only protect workers and patrons from secondhand smoke but also encourage smokers to quit, help them succeed, and create a social environment less conducive to smoking. The impact of policy changes can be amplified by promoting quitting around the date they are implemented. Outreach to health practitioners can alert them to encourage their patients to quit. Earned and paid media can also be used to motivate smokers to quit when policy changes are put into effect. Although these policies and efforts regarding them can generate great demand for evidence-based cessation services such as counseling and medication, it is important to make these resources available for those wanting to quit. Public and private health insurance plans should provide coverage for cessation services, and states should invest tobacco tax and/or tobacco settlement dollars in smoking-cessation programs as recommended by the CDC. Finally, the Family Smoking Prevention and Tobacco Control Act has given the U.S. Food and Drug Administration new authority to regulate tobacco products and marketing, and to prevent tobacco companies from deceptively marketing new products that discourage smokers from quitting and keep them addicted. 2010 American Journal of Preventive Medicine.

Developing smokeless tobacco products for smokers: an examination of tobacco industry documents.

Science.gov (United States)

Carpenter, C M; Connolly, G N; Ayo-Yusuf, O A; Wayne, G Ferris

2009-02-01

To investigate whether development of smokeless tobacco products (SLT) is intended to target current smokers. This study analysed internal tobacco industry documents to describe research related to the smokeless tobacco market. Relevant documents included those detailing the development and targeting of SLT products with a particular emphasis on moist snuff. Cigarette and SLT manufacturers recognised that shifting demographics of SLT users, as well as indoor smoking restrictions, health concerns and reduced social acceptability of smoking could impact the growth of the SLT market. Manufacturers developed new SLT products to target cigarette smokers promoting dual cigarette and SLT use. Heavy marketing of new SLT products may encourage dual use and result in unknown public health effects. SLT products have been designed to augment cigarette use and offset regulatory strategies such as clean indoor air laws. In the United States, the SLT strategy may provide cigarette companies with a diversified range of products under the prospect of federal regulation. These products may pose significant challenges to efforts by federal agencies to reduce harm caused by tobacco use.

Away with tobacco? On the early understandings of tobacco as a problem and the associated attempts at political regulation of tobacco in Norway 1900–1930

Directory of Open Access Journals (Sweden)

Sæbø Gunnar

Full Text Available BACKGROUND - In the early 1900s, the industrialization of cigarette production rapidly created the first major expansion in tobacco consumption in modern times. AIMS - This article focuses on the “tobacco problem” as it was understood, debated and sought governed in Norway around the time of the First World War. I identify various attempts to define tobacco as a problem, including arguments put forward by the anti-tobacco movement, the medical profession and politicians. How were health, moral-aesthetic and economic conditions articulated and integrated in these arguments? What (if any addictive elements of smoking were in focus? I also discuss the association between perceptions of the tobacco problem and political attempts to regulate it. There were repeated calls for a state tobacco monopoly to be introduced and municipal licensing system for the sale of cigarettes. DATA - The data are sourced from the journals Tobakskampen (The Tobacco Fight, the journal of the norwegian medical association and parliamentary documents. FINDINGS - The findings suggest that a to the extent tobacco was perceived as a social problem, it was a moral one (vice, not a behavioural and dependency problem, which alcohol was perceived to be at the time; b proposals to establish a tobacco monopoly were based on economic arguments only, and lacked any firm connection to social issues, health and morality; and c the anti-tobacco movement was socially marginal and their commitment to the municipal licensing idea resulted in large regional variations in public support, too large in fact for the idea to be effective. Although the government did not introduce regulations in the 1920s, the industrialization of cigarettes and subsequent developments in advertising caused a “moral panic” among tobacco opponents and created the modern climate of opinion regarding tobacco.

State political ideology, policies and health behaviors: The case of tobacco.

Fox, Ashley M; Feng, Wenhui; Yumkham, Rakesh

2017-05-01

Anti-smoking campaigns are widely viewed as a success case in public health policy. However, smoking rates continue to vary widely across U.S. states and the success of anti-smoking campaigns is contingent upon states' adoption of anti-smoking policies. Though state anti-smoking policy is a product of a political process, studies of the effect of policies on smoking prevalence have largely ignored how politics shapes policy adoption, which, in turn, impact state health outcomes. Policies may also have different effects in different political contexts. This study tests how state politics affects smoking prevalence both through the policies that states adopt (with policies playing a mediating role on health outcomes) or as an effect modifier of behavior (tobacco control policies may work differently in states in which the public is more or less receptive to them). The study uses publicly available data to construct a time-series cross-section dataset of state smoking prevalence, state political context, cigarette excise taxes, indoor smoking policies, and demographic characteristics from 1995 to 2013. Political ideology is measured using a validated indicator of the ideology of state legislatures and of the citizens of a state. We assess the relationship between state political context and state smoking prevalence rates adjusting for demographic characteristics and accounting for the mediating/moderating role of state policies with time and state fixed effects. We find that more liberal state ideology predicts lower adult smoking rates, but that the relationship between state ideology and adult smoking prevalence is only partly explained by state anti-smoking policies.

Yang, H.; Lucas, G. B.

1970-01-01

Ten fungi, Aspergillus niger, A. flavus, A. ochraceus, A. ruber, A. repens, A. amstelodami, Alternaria tenuis, Penicillium brevi-compactum, Cladosporium herbarum, and Chaetomium dolicotrichum, were isolated from moldy flue-cured tobacco and grown in various mixtures of N2-O2 or CO2-O2. A 1 to 5% concentration of O2 in an N2 atmosphere caused the greatest change in growth of the nine species, and a 10 to 20% concentration of O2 for A. flavus. All species, except A. amstelodami and A. ruber, grew faster in air than in mixtures containing 10% O2. High O2 concentrations generally inhibited furrow production in the mycelial mats. In an atmosphere of 5 to 40% O2 in the N2 atmosphere, furrows formed in mycelial mats between 5 and 40% O2 in the species except for A. ruber, A. repens, and A. amstelodami, which produced none in any concentration. As O2 decreased below 20%, spore production was progressively decreased, colony color faded to white, and cleistothecia formation was suppressed. In CO2-O2 mixtures radial growth of all species increased with each quantitative decrease of CO2. All species except A. niger grew faster in air than in 10% CO2. In contrast to N2-O2 mixtures, the fungi formed furrows, sporulation and cleistothecial formation were suppressed, and colony color changed to white in higher O2 concentrations. PMID:5461786

Cigarette smoking is the leading preventable cause of death in the United States. Of those who smoke, 9 out of 10 report trying their first cigarette before the age of 18. Although most people who initiate tobacco use are teenagers, animal models for studying tobacco dependence have traditionally focused on how adult animals initiate, withdrawal from and relapse to cigarette smoking. Furthermore, cigarette smoke contains more than 7,000 constituents, including nicotine, yet pre-clinical resea...

A flexible cure rate model with dependent censoring and a known cure threshold.

Science.gov (United States)

Bernhardt, Paul W

2016-11-10

We propose a flexible cure rate model that accommodates different censoring distributions for the cured and uncured groups and also allows for some individuals to be observed as cured when their survival time exceeds a known threshold. We model the survival times for the uncured group using an accelerated failure time model with errors distributed according to the seminonparametric distribution, potentially truncated at a known threshold. We suggest a straightforward extension of the usual expectation-maximization algorithm approach for obtaining estimates in cure rate models to accommodate the cure threshold and dependent censoring. We additionally suggest a likelihood ratio test for testing for the presence of dependent censoring in the proposed cure rate model. We show through numerical studies that our model has desirable properties and leads to approximately unbiased parameter estimates in a variety of scenarios. To demonstrate how our method performs in practice, we analyze data from a bone marrow transplantation study and a liver transplant study. Copyright © 2016 John Wiley & Sons, Ltd.

Advertising Receptivity and Youth Initiation of Smokeless Tobacco.

Science.gov (United States)

Timberlake, David S

2016-07-28

Cross-sectional data suggests that adolescents' receptivity to the advertising of smokeless tobacco is correlated with use of chewing tobacco or snuff. Lack of longitudinal data has precluded determination of whether advertising receptivity precedes or follows initiation of smokeless tobacco. The objective of this study was to test for the association between advertising receptivity and subsequent initiation of smokeless tobacco among adolescent males. Adolescent males from the 1993-1999 Teen Longitudinal California Tobacco Survey were selected at the baseline survey for never having used smokeless tobacco. Separate longitudinal analyses corresponded to two dependent variables, ever use of smokeless tobacco (1993-1996; N = 1,388) and use on 20 or more occasions (1993-1999; N = 1,014). Models were adjusted for demographic variables, risk factors for smokeless tobacco use, and exposure to users of smokeless tobacco. Advertising receptivity at baseline was predictive of ever use by late adolescence (RR(95% CI) = 2.0 (1.5, 2.8)) and regular use by young adulthood (RR(95% CI) = 3.7 (2.1, 6.7)) in models that were adjusted for covariates. Conclusions/ Importance: The findings challenge the tobacco industry's assertion that tobacco marketing does not impact youth initiation. This is particularly relevant to tobacco control in the United States because the 2009 Tobacco Control Act places fewer restrictions on smokeless tobacco products compared to cigarettes.

Google Trends is an innovative monitoring system with unique potential to monitor and predict important phenomena that may be occurring at a population level. We sought to validate whether Google Trends can additionally detect regional trends in youth and adult tobacco use. We compared 2011 Google Trends relative search volume data for cigars, cigarillos, little cigars and smokeless tobacco with state prevalence of youth (grades 9-12) and adult (age 18 and older) use of these products using data from the 2011 United States state-level Youth Risk Behaviors Surveillance System and the 2010-2011 United States National Survey on Drug Use and Health (NSDUH), respectively. We used the Pearson correlation coefficient to measure the associations. We found significant positive correlations between state Google Trends cigar relative search volume and prevalence of cigar use among youth (r=0.39, R(2) = 0.154, p=0.018) and adults (r=0.49, R(2) = 0.243, pGoogle Trends smokeless tobacco relative search volume and prevalence of smokeless tobacco use among youth and adults were both positive and significant (r=0.46, R(2) = 0.209, p=0.003 and r=0.48, R(2) = 0.226, pGoogle Trends has the potential to be a valuable monitoring tool for tobacco use.

Relaxed Poisson cure rate models.

Science.gov (United States)

Rodrigues, Josemar; Cordeiro, Gauss M; Cancho, Vicente G; Balakrishnan, N

2016-03-01

The purpose of this article is to make the standard promotion cure rate model (Yakovlev and Tsodikov, ) more flexible by assuming that the number of lesions or altered cells after a treatment follows a fractional Poisson distribution (Laskin, ). It is proved that the well-known Mittag-Leffler relaxation function (Berberan-Santos, ) is a simple way to obtain a new cure rate model that is a compromise between the promotion and geometric cure rate models allowing for superdispersion. So, the relaxed cure rate model developed here can be considered as a natural and less restrictive extension of the popular Poisson cure rate model at the cost of an additional parameter, but a competitor to negative-binomial cure rate models (Rodrigues et al., ). Some mathematical properties of a proper relaxed Poisson density are explored. A simulation study and an illustration of the proposed cure rate model from the Bayesian point of view are finally presented. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

1981-01-01

A curing for a polyepoxide is described which contains a divalent aryl radical such as phenylene a tetravalent aryl radical such as a tetravalent benzene radical. An epoxide is cured by admixture with the curing agent. The cured epoxy product retains the usual properties of cured epoxides and, in addition, has a higher char residue after burning, on the order of 45% by weight. The higher char residue is of value in preventing release to the atmosphere of carbon fibers from carbon fiber-epoxy resin composites in the event of burning of the composite.

[Tobacco smoking and principles of the who framework convention on tobacco control: a review].

Melkadze, N

2013-02-01

The aim of a review is to examine the current state of the relevant publications on tobacco smoking, the Guidelines on Protection from Exposure to Tobacco Smoke, and WHO Framework Convention on Tobacco Control (FCTC), which commits countries to protect the public's health by adopting various measures to reduce demand for tobacco. Georgia ratified the treaty in February 2006. In Georgia the implementation of the WHO FCTC is regulated by the "Law on Tobacco Control" (Law). It went into effect in September 2003. Changes and additions to the Law were approved by the Parliament in December 2008 (N 941 - rs) and in December 2010 (№4059-rs). According to Article 10 of the Law, smoking is prohibited at the educational and childcare institutions, medical and pharmaceutical facilities, at the entire area of petrol, gas and gas-distribution stations, in public transport, indoor areas of work and mass gathering... In spite of the legislation rights of non-smokers are very poorly preserved. With this in mind, the Welfare Foundation, the FCTC and the Tobacco Control Alliance, organized a public discussion on enforcing smoke-free laws in Georgia, in December 2012 at Tbilisi Marriott Courtyard Hotel. In order to make public libraries, educational, cultural institutions «de jure» and «de facto» free from tobacco smoke, the campaign against tobacco, which aims to strengthen implementation of the Tobacco Control Law and Regulation should be held in public libraries - not in the hotels. It is necessary to hang a poster - «Environment free from Smoke» at the entrance to buildings where smoking is prohibited throughout. In Rules and regulations for the use of the library there must be a note: smoking is prohibited in the library. We hope that Georgia in the nearest future will be in the list of countries with smoke-free public and work places.

The National Comprehensive Cancer Control Program (NCCCP) and National Tobacco Control Program (NTCP) are both well-positioned to promote the use of population-based tobacco cessation interventions, such as state quitlines and Web-based interventions. This paper outlines the methodology used to conduct a comparative effectiveness research study of traditional and Web-based tobacco cessation and quitline promotion approaches. A mixed-methods study with three components was designed to address the effect of promotional activities on service usage and the comparative effectiveness of population-based smoking cessation activities across multiple states. The cessation intervention component followed 7,902 smokers (4,307 quitline users and 3,595 Web intervention users) to ascertain prevalence of 30-day abstinence rates 7 months after registering for smoking cessation services. User characteristics and quit success was compared across the two modalities. In the promotions component, reach and use of traditional and innovative promotion strategies were assessed for 24 states, including online advertising, state Web sites, social media, mobile applications, and their effects on quitline call volume. The partnership intervention component studied the extent of collaboration among six selected NCCCPs and NTCPs. This study will guide program staff and clinicians with evidence-based recommendations and best practices for implementation of tobacco cessation within their patient and community populations and establish an evidence base that can be used for decision making.

Coalitions that were defunded but had access to the multimedia Enhanced Web site during the Fully Funded period and after defunding continued to use it (treatment group × funding status × period, F(3,714) = 3.18, P = .0234). Coalitions with access to the Basic Web site had low Web site use throughout and use by defunded coalitions was nearly zero when funding ceased. Members in defunded Basic Web site coalitions reported that their coalitions functioned worse than defunded Enhanced Web site coalitions (coalition development: group × status, F(1,360) = 4.81, P = .029; conflict resolution: group × status, F(1,306) = 5.69, P = .018; leadership satisfaction: group × status, F(1,342) = 5.69, P = .023). The Enhanced Web site may have had a protective effect on defunded coalitions. Defunded coalitions may have increased their capacity by using the Enhanced Web site when fully funded or by continuing to use the available online resources after defunding

US tobacco export to Third World: Third World War.

Global tobacco-related mortality will rise from the current 2.5 million to over 10 million annually by 2050. Most of this increase will occur in developing countries, where legislative controls and other measures that succeed in limiting the use of tobacco in industrialized countries do not exist or are at best inadequate. Of particular concern is the penetration of developing countries by the transnational tobacco companies, with aggressive promotional campaigns that include specific targeting of women, few of whom currently smoke in developing countries. The transnational tobacco companies advertise and market in ways long banned in the United States, for example, selling cigarettes without health warnings, advertising on television, and selling cigarettes with higher tar content than the same cigarettes sold in the United States. Also, tobacco advertising revenue prevents the media from reporting on the hazards of tobacco, a particularly serious problem in developing countries, where awareness of the harmfulness of tobacco is low. The transnational tobacco companies interfere with the national public health laws of developing countries via political and commercial pressures to open markets and to promote foreign cigarettes. This has led to an increase in market share by foreign cigarettes, but evidence also points to market expansion, especially among young people. The entry of the transnationals leads to a collapse of national tobacco monopolies or to their changing from unsophisticated government departments that may still cooperate with health initiatives on tobacco to copying the aggressive marketing and promotional behavior of the transnationals.(ABSTRACT TRUNCATED AT 250 WORDS)

Electron beam curing of composites is a nonthermal, nonautoclave curing process offering the following advantages compared to conventional thermal curing: substantially reduced manufacturing costs and curing times; improvements in part quality and performance; reduced environmental and health concerns; and improvements in material handling. In 1994 a Cooperative Research and Development Agreement (CRADA), sponsored by the Department of Energy Defense Programs and 10 industrial partners, was established to advance electron beam curing of composites. The CRADA has successfully developed hundreds of new toughened and untoughened resins, offering unlimited formulation and processing flexibility. Several patent applications have been filed for this work. Composites made from these easily processable, low shrinkage material match the performance of thermal cured composites and exhibit: low void contents comparable to autoclave cured composites (less than 1%); superb low water absorption values in the same range as cyanate esters (less than 1%); glass transition temperatures rivaling those of polyimides (greater than 390 C); mechanical properties comparable to high performance, autoclave cured composites; and excellent property retention after cryogenic and thermal cycling. These materials have been used to manufacture many composite parts using various fabrication processes including hand lay-up, tow placement, filament winding, resin transfer molding and vacuum assisted resin transfer molding

During the curing process of light curing dental composites the mobility of molecules and molecule segments is reduced leading to a significant increase of the viscosity as well as the ion viscosity. Thus, the kinetics of the curing behavior of 6 different composites was derived from dielectric analysis (DEA) using especially redesigned flat sensors with interdigit comb electrodes allowing for irradiation at the top side and measuring the ion viscosity at the bottom side. As the ion viscosities of dental composites change 1-3 orders of magnitude during the curing process, DEA provides a sensitive approach to evaluate their curing behavior, especially in the phase of undisturbed chain growth. In order to determine quantitative kinetic parameters a kinetic model is presented and examined for the evaluation of the ion viscosity curves. From the obtained results it is seen that DEA might be employed in the investigation of the primary curing process, the quality assurance of ingredients as well as the control of processing stability of the light curing dental composites.

Residual Stress Developed During the Cure of Thermosetting Polymers: Optimizing Cure Schedule to Minimize Stress.

Energy Technology Data Exchange (ETDEWEB)

Kropka, Jamie Michael; Stavig, Mark E.; Jaramillo, Rex

2016-06-01

When thermosetting polymers are used to bond or encapsulate electrical, mechanical or optical assemblies, residual stress, which often affects the performance and/or reliability of these devices, develops within the structure. The Thin-Disk-on-Cylinder structural response test is demonstrated as a powerful tool to design epoxy encapsulant cure schedules to reduce residual stress, even when all the details of the material evolution during cure are not explicitly known. The test's ability to (1) distinguish between cohesive and adhesive failure modes and (2) demonstrate methodologies to eliminate failure and reduce residual stress, make choices of cure schedules that optimize stress in the encapsulant unambiguous. For the 828/DEA/GMB material in the Thin-Disk-on-Cylinder geometry, the stress associated with cure is significant and outweighs that associated with cool down from the final cure temperature to room temperature (for measured lid strain, Scure I > I I e+h erma * II) * The difference between the final cure temperature and 1 1 -- the temperature at which the material gels, Tf-T ge i, was demonstrated to be a primary factor in determining the residual stress associated with cure. Increasing T f -T ge i leads to a reduction in cure stress that is described as being associated with balancing some of the 828/DEA/GMB cure shrinkage with thermal expansion. The ability to tune residual stress associated with cure by controlling T f -T ge i would be anticipated to translate to other thermosetting encapsulation materials, but the times and temperatures appropriate for a given material may vary widely.

A Model To Estimate the Sources of Tobacco-Specific Nitrosamines in Cigarette Smoke.

Lipowicz, Peter J; Seeman, Jeffrey I

2017-08-21

Tobacco-specific nitrosamines (TSNAs) are one of the most extensively and continually studied classes of compounds found in tobacco and cigarette smoke.1-5 The TSNAs N-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) have been characterized by the US Food and Drug Administration (FDA) as harmful and potentially harmful constituents in tobacco products,6 and cigarette manufacturers report their levels in cigarette tobacco filler and cigarette smoke to the FDA. NNN and NNK are classified by IARC as carcinogenic to humans.7 TSNAs transfer from tobacco to smoke by evaporation driven by heat and the flow of gases down the cigarette rod. Other TSNA sources in smoke include pyrorelease, where room temperature-unextractable TSNAs are released by smoking, and pyrosynthesis, where TSNAs are formed by reactions during smoking. We propose the first model that quantifies these three sources of TSNA in smoke. In our model, evaporative transfer efficiency of a TSNA is equated to the evaporative transfer efficiency of nicotine. Smoke TSNA measured in excess of what is transferred by evaporation is termed "pyrogeneration," which is the net sum of pyrorelease and pyrosynthesis minus pyrodegredation. This model requires no internal standard, is applicable to commercial cigarettes "as is," and uses existing analytical methods. This model was applied to archived Philip Morris USA data. For commercial blended cigarettes, NNN pyrogeneration appears to be unimportant, but NNK pyrogeneration contributes roughly 30-70% of NNK in smoke with the greater contribution at lower tobacco NNK levels. This means there is an opportunity to significantly reduce smoke NNK by up to 70% if pyrogeneration can be decreased or eliminated, perhaps by finding a way to grow and cure tobacco with reduced matrix-bound NNK. For burley research cigarettes, pyrogeneration may account for 90% or more of both NNN and NNK in smoke.

Full Text Available This study evaluated the Knoop Hardness (KHN values of two dual-cured composite resin core build-up materials and one resin cement exposed to different curing conditions. Two dual-cured core build-up composite resins (LuxaCore®-Dual, DMG; and FluoroCore®2, Dentsply Caulk, and one dual-cured resin cement (Rely X ARC, 3M ESPE were used in the present study. The composite materials were placed into a cylindrical matrix (2 mm in height and 3 mm in diameter, and the specimens thus produced were either light-activated for 40 s (Optilux 501, Demetron Kerr or were allowed to self-cure for 10 min in the dark (n = 5. All specimens were then stored in humidity at 37°C for 24 h in the dark and were subjected to KHN analysis. The results were submitted to 2-way ANOVA and Tukey's post-hoc test at a pre-set alpha of 5%. All the light-activated groups exhibited higher KHN values than the self-cured ones (p = 0.00001, regardless of product. Among the self-cured groups, both composite resin core build-up materials showed higher KHN values than the dual-cured resin cement (p = 0.00001. LuxaCore®-Dual exhibited higher KHN values than FluoroCore®2 (p = 0.00001 when they were allowed to self-cure, while no significant differences in KHN values were observed among the light-activated products. The results suggest that dual-cured composite resin core build-up materials may be more reliable than dual-cured resin cements when curing light is not available.

Uncured pork legs from the right side of 18 carcasses were treated with a Ross Tenderizer and the left side were controls. All 36 samples were dry-cured for 40, 56 or 70 days and evaluated for appearance traits, cure penetration characteristics, microbial load, Kramer Shear force and taste attributes. The tenderization treatment had no effect (P > 0·05) on visual color or cure penetration rate, weight loss before curing, percentage moisture, nitrate level, nitrite level, total plate count, anaerobic counts, psychrotrophic counts, objective and subjective tenderness measurements or juiciness. However, the higher values of salt suggested a possible acceleration of the dry cure penetration process among the tenderized samples. Cure time had no effect (P > 0·05) on percentage moisture, percentage salt, nitrate content, nitrite content, shear force and juiciness. Results suggest a limited effect of the mechanical tenderization process on certain traits related to dry curing and that total process time should be at least 70 days if color stability during cooking is desired.

Gruchot Andrzej

2015-06-01

Full Text Available The paper presents results of research on the influence of compaction and air and water curing on angle of internal friction and cohesion of fluidized fly ash from “Połaniec” Power Plant. It was stated that the increase in compaction resulted in an insignificant increase of the angle of internal friction and a quite significant increase of cohesion. While the type and time of curing had a great influence on the angle of internal friction and cohesion. The highest values of angle of internal friction were obtained in the air curing, and the lowest in the water curing whereas in case of cohesion there was an inverse relation. The rise of curing time resulted in largely increased cohesion and small changes of angle of internal friction.

During the 20th century, use of tobacco products contributed to the deaths of 100 million persons worldwide. In 2011, approximately 6 million additional deaths were linked to tobacco use, the world's leading underlying cause of death, responsible for more deaths each year than human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS), tuberculosis, and malaria combined. One third to one half of lifetime users die from tobacco products, and smokers die an average of 14 years earlier than nonsmokers. Manufactured cigarettes account for 96% of all tobacco sales worldwide. From 1880 to 2009, annual global consumption of cigarettes increased from an estimated 10 billion cigarettes to approximately 5.9 trillion cigarettes, with five countries accounting for 58% of the total consumption: China (38%), Russia (7%), the United States (5%), Indonesia (4%), and Japan (4%). Among the estimated 1 billion smokers worldwide, men outnumber women by four to one. In 14 countries, at least 50% of men smoke, whereas in more than half of these same countries, fewer than 10% of women smoke. If current trends persist, an estimated 500 million persons alive today will die from use of tobacco products. By 2030, tobacco use will result in the deaths of approximately 8 million persons worldwide each year. Yet, every death from tobacco products is preventable.

Promoting tobacco through the international language of dance music: British American Tobacco and the Ministry of Sound

Stanton, Caitlin R.; Chu, Alexandria; Collin, Jeff

2011-01-01

Background: Tobacco companies target young adults through marketing strategies that use bars and nightclubs to promote smoking. As restrictions increasingly limit promotions, music marketing has become an important vehicle for tobacco companies to shape brand image, generate brand recognition and promote tobacco. Methods: Analysis of previously secret tobacco industry documents from British American Tobacco, available at http://legacy.library.ucsf.edu. Results: In 1995, British American Tobacco (BAT) initiated a partnership with London’s Ministry of Sound (MOS) nightclub to promote Lucky Strike cigarettes to establish relevance and credibility among young adults in the UK. In 1997, BAT extended their MOS partnership to China and Taiwan to promote State Express 555. BAT sought to transfer values associated with the MOS lifestyle brand to its cigarettes. The BAT/MOS partnership illustrates the broad appeal of international brands across different regions of the world. Conclusion: Transnational tobacco companies like BAT are not only striving to stay contemporary with young adults through culturally relevant activities such as those provided by MOS but they are also looking to export their strategies to regions across the world. Partnerships like this BAT/MOS one skirt marketing restrictions recommended by the World Health Organization’s Framework Convention on Tobacco Control. The global scope and success of the MOS program emphasizes the challenge for national regulations to restrict such promotions. PMID:20159772

Estimation of state and material properties during heat-curing molding of composite materials using data assimilation: A numerical study

Full Text Available Accurate simulations of carbon fiber-reinforced plastic (CFRP molding are vital for the development of high-quality products. However, such simulations are challenging and previous attempts to improve the accuracy of simulations by incorporating the data acquired from mold monitoring have not been completely successful. Therefore, in the present study, we developed a method to accurately predict various CFRP thermoset molding characteristics based on data assimilation, a process that combines theoretical and experimental values. The degree of cure as well as temperature and thermal conductivity distributions during the molding process were estimated using both temperature data and numerical simulations. An initial numerical experiment demonstrated that the internal mold state could be determined solely from the surface temperature values. A subsequent numerical experiment to validate this method showed that estimations based on surface temperatures were highly accurate in the case of degree of cure and internal temperature, although predictions of thermal conductivity were more difficult.

Gan, C Y

1998-09-01

As part of a larger study to bring attention to smoking and smokeless tobacco use among the indigenous people of Sabah State in Malaysia, the Bajaus were interviewed in a cross-sectional survey. 74.4% of the men smoked compared to 3.3% of the women and 77% of women used smokeless tobacco compared to 4.3% of men. Local handrolled cigarettes called kirais were popular and smokeless tobacco was used as an ingredient in the ritual of betel-quid chewing. Tobacco was also used because it was thought to have medicinal effects. The prevalence of smokeless tobacco use was significantly lower among the better educated women but for smoking, education had no relation with prevalence. Both habits could be easily maintained as they were cheap practices which were socially and culturally accepted. Awareness of the adverse effects of such tobacco habits was poor and intervention programs to curb tobacco use is required.

Although the United States Air Force (USAF) has been a leader in efforts to reduce tobacco use among service members, tobacco continues to be a problem and initiatives to decrease tobacco use further require buy-in from leadership. We explored line leaderships' perspectives on tobacco. A diverse group of 10 senior commissioned and 10 non-commissioned personnel were interviewed. Respondents reported substantial changes in the culture of tobacco use during their years of service, from near ubiquity to restricted use areas. They also perceived mixed messages coming from the USAF, including simultaneous discouragement of and accommodations for tobacco use, and variability in policies and enforcement. Many respondents indicated that allowing tobacco use creates conflict and undermines military discipline and suggested that a tobacco-free policy would be the best way to eliminate these contradictions. Although there has been substantial movement away from a culture of tobacco in the USAF, current policies and variable enforcement of these policies create unnecessary contradictions. Establishing a tobacco-free service would resolve these issues in addition to improving the health of service members and veterans.

Curing behavior and thermal properties of trifunctional epoxy resin cured by 4, 4’-diaminodiphenyl sulfone

Full Text Available A novel trifunctional epoxy resin 4-(3, 3-dihydro-7-hydroxy-2, 4, 4-trimethyl-2H-1-benzopyran-2-yl-1, 3-benzenediol glycidyl (shorted as TMBPBTH-EPOXY was synthesized in our lab to improve thermal performance. Its curing behavior and performance were studied by using 4, 4′-diaminodiphenyl sulfone (DDS as hardener with the mass ratio of 100:41 of TMBPBTH-EPOXY and DDS. The curing activation energy was investigated by differential scanning calorimetry (DSC to be 64.0 kJ/mol estimated by Kissinger’s method and 68.7 kJ/mol estimated by Flynn-Wall-Ozawa method respectively. Thermogravimetric analyzer (TGA was used to investigate the thermal decomposition of cured compounds. It was found that when curing temperature was lower than 180°C, the thermal decomposition temperature increased with the rise of curing temperature and curing time. On the other hand, when the curing temperature was higher than 180°C, the thermal decomposition temperature went down instead with the increase of curing time that might be the over-crosslinking of TMBPBTH-EPOXY and DDS hardener. The glass transition temperature (Tg of cured TMBPBTH-EPOXY/DDS compound determined by dynamic mechanical thermal analysis (DMTA is 290.1°C.

The aim of this study was to evaluate the degree of conversion and Vickers surface hardness of resin cement under a simulated ceramic restoration with 3 different curing units: a conventional halogen unit, a high-intensity halogen unit, and a light-emitting diode system. A conventional halogen curing unit (Hilux 550) (40 s), a high-intensity halogen curing unit used in conventional and ramp mode (Optilux 501) (10 s and 20 s, respectively), and a light-emitting diode system (Elipar FreeLight) (20 s, 40 s) were used in this study. The dual-curing resin cement (Variolink II) was cured under a simulated ceramic restoration (diameter 5 mm, height 2 mm), and the degree of conversion and Vickers surface hardness were measured. For degree of conversion measurement, 10 specimens were prepared for each group. The absorbance peaks were recorded using the diffuse-reflection mode of Fourier transformation infrared spectroscopy. For Vickers surface hardness measurement, 10 specimens were prepared for each group. A load of 200 N was applied for 15 seconds, and 3 evaluations of each of the samples were performed. Degree of conversion achieved with Optilux 501 (20 s) was significantly higher than those of Hilux, Optilux 501 (10 s), Elipar FreeLight (20 s), and Elipar FreeLight (40 s). For Vickers surface hardness measurement, Optilux 501 (20 s) produced the highest surface hardness value. No significant differences were found among the Hilux, Optilux 501 (10 s), Elipar FreeLight (20 s), and Elipar FreeLight (40 s). The high-intensity halogen curing unit used in ramp mode (20 s) produced harder resin cement surfaces than did the conventional halogen curing unit, high-intensity halogen curing unit used in conventional mode (10 s) and light-emitting diode system (20 s, 40 s), when cured through a simulated ceramic restoration.

Behavioral Economic Laboratory Research in Tobacco Regulatory Science.

Research that can provide a scientific foundation for the United States Food and Drug Administration (FDA) tobacco policy decisions is needed to inform tobacco regulatory policy. One factor that affects the impact of a tobacco product on public health is its intensity of use, which is determined, in part, by its abuse liability or reinforcing efficacy. Behavioral economic tasks have considerable utility for assessing the reinforcing efficacy of current and emerging tobacco products. This paper provides a narrative review of several behavioral economic laboratory tasks and identifies important applications to tobacco regulatory science. Behavioral economic laboratory assessments, including operant self-administration, choice tasks and purchase tasks, can be used generate behavioral economic data on the effect of price and other constraints on tobacco product consumption. These tasks could provide an expedited simulation of the effects of various tobacco control policies across populations of interest to the FDA. Tobacco regulatory research questions that can be addressed with behavioral economic tasks include assessments of the impact of product characteristics on product demand, assessments of the abuse liability of novel and potential modified risk tobacco products (MRTPs), and assessments of the impact of conventional and novel products in vulnerable populations.

Change in tobacco excise policy in Bulgaria: the role of tobacco industry lobbying and smuggling.

To examine how transnational tobacco companies (TTCs) tried to penetrate the Bulgarian cigarette market and influence tobacco excise tax policy after the fall of communism and during Bulgaria's accession to the European Union (EU). Analysis of internal tobacco industry documents supplemented by analysis of press coverage, tobacco industry journals, market reports and key informant interviews. TTCs have been involved in cigarette smuggling to and through Bulgaria since at least 1975 and used smuggling as a market-entry strategy. National tobacco company Bulgartabac appears to have been involved in smuggling its own cigarettes from and reimporting them to Bulgaria. Since Bulgaria's accession to the EU opened the market to the TTCs, TTCs have exaggerated the scale of the illicit trade to successfully convince politicians and public health experts that tax increases lead to cigarette smuggling. Yet, sources point to TTCs' continued complicity in cigarette smuggling to and through Bulgaria between 2000 and 2010. TTCs aimed to influence the Bulgarian tobacco excise tax regime, import duties and pricing mechanism, but appear to have been less successful than in other former communist countries in part due to the co-existence of a state-owned tobacco company. Undisclosed meetings between the tobacco industry and government ministers and officials are ongoing despite Bulgaria being a party to the Framework Convention on Tobacco Control (FCTC). The TTCs continued involvement in smuggling suggests that deals in 2004, 2007 and 2010 which the European Commission has reached with TTCs to address cigarette smuggling are inadequate. The TTCs' continued access to policymakers suggests that the FCTC is not being properly implemented. Published by the BMJ Publishing Group Limited.

about 10% of the smokers stated that the doctor offered to help them stop smoking, and just 25% of all parents/guardians indicated that the doctor offered to help them stop exposing their children to ETS in the home or elsewhere. Parents of children brought to Continuity Clinic may benefit from advice and assistance on quitting cigarette smoking and protecting their children from ETS. While pediatric residents offer advice and encouragement, few provide the assistance parents require. These findings underscore the importance of training pediatric residents to address tobacco with the parents/guardians of the patients they serve.

Using real-time FTIR-ATR and stationary or pulsed monochromatic (313 nm) irradiation chemical and physical factors affecting the curing speed of printing inks such as nature and concentration of photo-initiators, reactivity of the ink binding system, ink thickness and pigmentation, irradiance in the curing plane, oxygen concentration and nitrogen inerting, multiple pulse exposure, the photochemical dark reaction and temperature dependence were studied. The results were used to select optimum conditions for excimer UV curing in respect to ink reactivity, nitrogen inerting and UV exposure and to build an excimer UV curing unit consisting of two 50 W/cm 308 run excimer lamps, power supply, cooling and inerting unit. The excimer UV curing devices were tested under realistic conditions on a web offset press zirkon supra forte and a sheet fed press Heidelberg GTO 52. Maximum curing speeds of 300 m/min in web offset and 8000 sheets per hour in sheet fed offset were obtained

Electron curing of surface coatings

Nablo, S.V.

1974-01-01

The technical development of electron curing of surface coatings has received great impetus since 1970 from dramatic changes in the economics of the conventional thermal process. The most important of these changes are reviewed, including: the Clear Air Act, increasing cost and restrictive allocation of energy, decreased availability and increased costs of solvents, competitive pressure for higher line productivity. The principles of free-radical initiated curing as they pertain to industrial coatings are reviewed. Although such electron initiated processes have been under active development for at least two decades, high volume production applications on an industrial scale have only recently appeared. These installations are surveyed with emphasis on the developments in machinery and coatings which have made this possible. The most significant economic advantages of electron curing are presented. In particular, the ability of electron curing to eliminate substrate damage and to eliminate the curing station (oven) as the pacing element for most industrial surface coating curing applications is discussed. Examples of several new processes of particular interest in the textile industry are reviewed, including the curing of transfer cast urethane films, flock adhesives, and graftable surface finishes

To investigate the effect of curing of composite cements and a new ceramic silanization pre-treatment on the micro-tensile bond strength (μTBS). Feldspathic ceramic blocks were luted onto dentin using either Optibond XTR/Nexus 3 (XTR/NX3; Kerr), the silane-incorporated 'universal' adhesive Scotchbond Universal/RelyX Ultimate (SBU/RXU; 3M ESPE), or ED Primer II/Panavia F2.0 (ED/PAF; Kuraray Noritake). Besides 'composite cement', experimental variables were 'curing mode' ('AA': complete auto-cure at 21°C; 'AA*': complete auto-cure at 37°C; 'LA': light-curing of adhesive and auto-cure of cement; 'LL': complete light-curing) and 'ceramic surface pre-treatment' ('HF/S/HB': hydrofluoric acid ('HF': IPS Ceramic Etching Gel, Ivoclar-Vivadent), silanization ('S': Monobond Plus, Ivoclar-Vivadent) and application of an adhesive resin ('HB': Heliobond, Ivoclar-Vivadent); 'HF/SBU': 'HF' and application of the 'universal' adhesive Scotchbond Universal ('SBU'; 3M ESPE, only for SBU/RXU)). After water storage (7 days at 37°C), ceramic-dentin sticks were subjected to μTBS testing. Regarding the 'composite cement', the significantly lowest μTBSs were measured for ED/PAF. Regarding 'curing mode', the significantly highest μTBS was recorded when at least the adhesive was light-cured ('LA' and 'LL'). Complete auto-cure ('AA') revealed the significantly lowest μTBS. The higher auto-curing temperature ('AA*') increased the μTBS only for ED/PAF. Regarding 'ceramic surface pre-treatment', only for 'LA' the μTBS was significantly higher for 'HF/S/HB' than for 'HF/SBU'. Complete auto-cure led to inferior μTBS than when either the adhesive (on dentin) or both adhesive and composite cement were light-cured. The use of a silane-incorporated adhesive did not decrease luting effectiveness when also the composite cement was light-cured. Copyright © 2013 Academy of Dental Materials.

Tobacco Industry Promotional Strategies Targeting American Indians/Alaska Natives and Exploiting Tribal Sovereignty.

Science.gov (United States)

Lempert, Lauren K; Glantz, Stanton A

2018-03-12

American Indians/Alaska Natives have the highest commercial tobacco use in the United States, resulting in higher tobacco-caused deaths and diseases than the general population. Some American Indians/Alaska Natives use commercial tobacco for ceremonial as well as recreational uses. Because federally-recognized Tribal lands are sovereign, they are not subject to state cigarette taxes and smokefree laws. This study analyzes tobacco industry promotional efforts specifically targeting American Indians/Alaska Natives and exploiting Tribal lands to understand appropriate policy responses in light of American Indians'/Alaska Natives' unique sovereign status and culture. We analyzed previously secret tobacco industry documents available at the Truth Tobacco Documents Library (https://industrydocuments.library.ucsf.edu/tobacco/). Tobacco companies used promotional strategies targeting American Indians/Alaska Natives and exploiting Tribal lands that leveraged the federally-recognized Tribes' unique sovereign status exempting them from state cigarette taxes and smokefree laws, and exploited some Tribes' existing traditional uses of ceremonial tobacco and poverty. Tactics included price reductions, coupons, giveaways, gaming promotions, charitable contributions and sponsorships. Additionally, tobacco companies built alliances with Tribal leaders to help improve their corporate image, advance ineffective "youth smoking prevention" programs, and defeat tobacco control policies. The industry's promotional tactics likely contribute to disparities in smoking prevalence and smoking-related diseases among American Indians//Alaska Natives. Proven policy interventions to address these disparities including tobacco price increases, cigarette taxes, comprehensive smokefree laws, and industry denormalization campaigns to reduce smoking prevalence and smoking-related disease could be considered by Tribal communities. The sovereign status of federally-recognized Tribes does not prevent them

[Lessons learned from tobacco control in Spain].

Science.gov (United States)

Fernández, Esteve; Villalbí, Joan R; Córdoba, Rodrigo

2006-01-01

The growing involvement in Spain by civil society in the demand for tobacco control policies has been notable. The basis for the creation of the National Committee for Tobacco Prevention was established in 2004. At the end of that year, an intensive intervention was aimed at specifying, in law, the regulatory actions in the National Plan for Tobacco Prevention. This would facilitate a qualitative leap, taking advantage of the legal transposition of the European directive on advertising. With broad political consensus, the Law 28/2005 was established regarding sanitary measures for tobacco and the regulation of the sale, supply and consumption of tobacco products. The objective stated in this law is to prevent the initiation of tobacco consumption, especially among youth, guarantee the right of non-smokers to breathe air free from tobacco smoke and make quitting this habit easier for people who wish to do so. The main issues included are the prohibition of tobacco advertising and the limitation of tobacco consumption in common work areas and enclosed public spaces. The new law has replaced the previous rules in Spain, which were some of the most permissive in the European Union in terms of tobacco sales, advertising limitations and restrictions on smoking locations. It is clear that there is still much to be done. At this time, more social support needs to be generated in favor of the new regulations, and an important effort needs to be made to educate the public.

2011-01-01

Background Smoking in Hollywood movies is a known risk factor for teen smoking in the USA and Europe, but little is known about the association between exposure to tobacco use in Bollywood movies and teen tobacco use in India. Methods A cross-sectional sample of 3956 adolescents (eighth and ninth grades, ages 12–16 years) from 12 randomly selected New Delhi schools was surveyed in 2009, assessing tobacco use status, receptivity to tobacco promotions (based on owning or being willing to wear tobacco-branded merchandise) and exposure to tobacco use in movies. Quartiles of exposure to tobacco use in popular Bollywood movies released from 2006 to 2008 (n=59) were determined by content coding them for tobacco use and querying the adolescents whether they had seen each one. Logistic regression was used to control for covariates including age, gender, parent education, school performance, sensation-seeking propensity, family and peer tobacco use, and authoritative parenting. Results Altogether, the 59 movies contained 412 tobacco use occurrences. The prevalence of ever tobacco use among adolescents was 5.3%. Compared with low-exposure adolescents (quartile 1), the adjusted odds of ever tobacco use among high-exposure adolescents (quartile 4) was 2.3 (95% CI 1.3 to 3.9). Being receptive to tobacco promotions was also associated with higher adjusted odds of ever tobacco use, 2.0 (95% CI 1.4 to 3.0). Conclusion Watching tobacco use in Bollywood movies and receptivity to tobacco promotional activities were both independently associated with ever tobacco use among adolescents in India, with ORs being similar to the studies of adolescents elsewhere.

This article examines state Master Settlement Agreement (MSA) funding of tobacco control in communities of color. The primary research question was whether MSA monies resulted in dedicated funding for communities of color at the state level. This article also explores some of the historical factors that shape the relationship of communities of color to MSA funding as well as some of the institutional barriers to implementing comprehensive tobacco control programs in these communities. Three model approaches to funding parity in tobacco control programs were examined as case studies. Because of the limited amount of research available in this area, the data on tobacco control funding for communities of color was collected in interviews with state tobacco control agencies during October 2003. Findings supported our hypothesis that there were few dedicated resources at the state level for tobacco control and prevention in communities of color.

To characterize the extent to which state and national professional pharmacy associations have implemented formal policies addressing the sale of tobacco and alcohol products in community pharmacies. To determine existence of tobacco and alcohol policies, national professional pharmacy associations (n = 10) and state-level pharmacy associations (n = 86) affiliated with the American Pharmacists Association (APhA) and/or the American Society of Health-System Pharmacists (ASHP) were contacted via telephone and/or e-mail, and a search of the association websites was conducted. Of 95 responding associations (99%), 14% have a formal policy opposing the sale of tobacco products in pharmacies and 5% have a formal policy opposing the sale of alcohol in pharmacies. Of the associations representing major tobacco-producing states, 40% have a formal policy against tobacco sales in pharmacies, significantly more than the 8% of non-tobacco state associations with such policies. Among national professional pharmacy associations, only APhA and ASHP have formal policy statements opposing the sale of both tobacco and alcohol in pharmacies. Most state-level professional pharmacy associations affiliated with these two national organizations have no formal policy statement or position.

Ribisl, Kurt M

2012-01-01

This paper is part of a collection that identifies research priorities that will help guide the efforts of the U.S. Food and Drug Administration (FDA) as it regulates tobacco products. This paper examines the major provisions related to tobacco product advertising, marketing, sales, and distribution included in Public Law 111-31, the "Family Smoking Prevention and Tobacco Control Act". This paper covers 5 areas related to (a) marketing regulations (e.g., ban on color and imagery in ads, ban on nontobacco gifts with purchase); (b) granting FDA authority over the sale, distribution, accessibility, advertising, and promotion of tobacco and lifting state preemption over advertising; (c) remote tobacco sales (mail order and Internet); (d) prevention of illicit and cross-border trade; and (e) noncompliant export products. Each of the 5 sections of this paper provides a description and brief history of regulation, what is known about this regulatory strategy, and research opportunities.

Containing diffusion: the tobacco industry's multipronged trade strategy to block tobacco standardised packaging.

Science.gov (United States)

Crosbie, Eric; Eckford, Robert; Bialous, Stella

2018-04-21

To analyse the tobacco industry's strategy of using trade and investment agreements to prevent the global diffusion of standardised packaging (SP) of tobacco products. Review of tobacco industry documents, relevant government documents and media items. The data were triangulated and thematically analysed. Internal tobacco industry documents reveal that during the early 1990s, tobacco companies developed a multipronged trade strategy to prevent the global diffusion of progressive tobacco packaging and labelling proposals, including SP. This strategy consisted of (1) framing the health issue in terms of trade and investment, (2) detailing alleged legal violations concerning trade barriers, intellectual property and investment rights, (3) threatening legal suits and reputational damage, and (4) garnering third-party support. These efforts helped delay SP until 2010 when Australia became the first country to reintroduce SP proposals, followed by governments in the UK and New Zealand in 2012, Ireland in 2013 and France in 2014. Review of government documents and media sources in each of the five countries indicate the industry continues to employ this multipronged strategy throughout the SP policy's progression. Although this strategy is tailored towards each domestic context, the overall tobacco industry's trade strategy remains consistently focused on shifting the attention away from public health and towards the realm of trade and investment with more corporate-friendly allies. Governments seeking to implement SP need to be prepared to resist and counter the industry's multipronged trade strategy by avoiding trade diversions, exposing false industry legal and reputational claims, and monitoring third-party support. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

DiFranza, J R; Norwood, B D; Garner, D W; Tye, J B

1987-06-26

Public health laws intended to prevent children from smoking have been enacted in many states. We surveyed the relevant laws in all states and the District of Columbia. The efficacy of one such law prohibiting the sale of tobacco to individuals under the age of 18 years was assessed with the cooperation of an 11-year-old girl. She was successful in 75 of 100 attempts to purchase cigarettes. On the basis of this experience and a review of existing laws, we have made recommendations for a model law. These include a prohibition of the possession of tobacco by minors, a prohibition of the sale of tobacco to minors, a requirement for a warning sign at the point of sale, a ban on cigarette vending machines, and a reward for individuals reporting violators of vending laws.

Can demand-side policies stop the tobacco industry's damage? Lessons from Turkey.

Science.gov (United States)

Gultekin-Karakas, Derya

2015-01-01

Trade and investment liberalisation in the post-1980 period allowed the penetration of transnational tobacco companies into the Turkish market. State control over the market was gradually removed and tobacco farming, manufacturing, trade and consumption were reshaped in line with the needs of transnational tobacco companies. The resultant increase in product proliferation and aggressive marketing strategies led to a dramatic rise in cigarette consumption in the 1990s, making Turkey a market with one of the sharpest consumption increases in the world. While Turkey implemented demand-side tobacco control policies to reduce consumption after 1996, it continued to stimulate manufacturing and trade in a conflicting way. The Turkish case verifies that the liberalisation process facilitated by the state under the auspices of international institutions conflicts with tobacco control. Liberalisation paves the way for market expansions of transnational tobacco companies that resist tobacco control in their drive for profit. Current global tobacco control policies, with no interest in controlling manufacturing, have limited effect on consumption. The Turkish case indicates the necessity of establishing public control over tobacco manufacturing and trade from a public health perspective.

Persistent tobacco use among racial and ethnic minority populations in the United States is a critical public health concern. Yet, potential sources of racial/ethnic disparities in tobacco use remain unclear. The present study examined racial/ethnic differences in tobacco withdrawal-a clinically-relevant underpinning of tobacco use that has received sparse attention in the disparities literature-utilizing a controlled laboratory design. Daily smokers (non-Hispanic African American [n = 178], non-Hispanic white [n = 118], and Hispanic [n = 28]) attended two counterbalanced sessions (non-abstinent vs. 16-hour abstinent). At both sessions, self-report measures of urge, nicotine withdrawal, and affect were administered and performance on an objective behavioral task that assessed motivation to reinstate smoking was recorded. Abstinence-induced changes (abstinent scores vs. non-abstinent scores) were analyzed as a function of race/ethnicity. Non-Hispanic African American smokers reported greater abstinence-induced declines in several positive affect states in comparison to other racial/ethnic groups. Relative to Hispanic smokers, non-Hispanic African American and non-Hispanic white smokers displayed larger abstinence-provoked increases in urges to smoke. No racial/ethnic differences were detected for a composite measure of nicotine withdrawal symptomatology, negative affect states, and motivation to reinstate smoking behavior. These results suggest qualitative differences in the expression of some components of tobacco withdrawal across three racial/ethnic groups. This research helps shed light on bio-behavioral sources of tobacco-related health disparities, informs the application of smoking cessation interventions across racial/ethnic groups, and may ultimately aid the overall effort towards reducing the public health burden of tobacco addiction in minority populations. The current study provides some initial evidence that there may be qualitative differences in the

Use of corporate sponsorship as a tobacco marketing tool: a review of tobacco industry sponsorship in the USA, 1995-99.

Science.gov (United States)

Rosenberg, N J; Siegel, M

2001-09-01

To describe the nature and extent of tobacco company sponsorship in the USA during the period 1995-99 and analyse this sponsorship in a marketing context. A cross-sectional study of tobacco company sponsorships identified through a customised research report from IEG Inc, and from internet web site searches. First, a customised report was received from IEG Inc, which identified sponsorship activities for Philip Morris, RJ Reynolds, Brown & Williamson, Lorillard, and US Tobacco for the years 1997 and 1998. Second, the internet was systematically searched for tobacco industry sponsorships during the period 1995-99 by the same parent companies and their respective brands. During the period 1995-99, tobacco companies sponsored at least 2733 events, programmes, and organisations in the USA. Sponsorships involved all 50 states and the District of Columbia, and the minimum total funding amount of these sponsorships was $365.4 million. Tobacco corporate sponsorships involved numerous small, community based organisations, both through direct funding and through grants to larger umbrella organisations, and many of these organisations were part of the public health infrastructure. Tobacco corporate sponsorship serves as an important marketing tool for tobacco companies, serving both a sales promotion and public relations function. Public health practitioners need to develop better surveillance systems for monitoring tobacco sponsorship, to seek out alternative funding sources for tobacco company sponsored events and organisations, and to consider promoting a ban on tobacco sponsorship, possibly linking such regulation to the creation of alternative funding sources.

A comparison of three policy approaches for tobacco retailer reduction.

2015-05-01

The Institute of Medicine recommends that public health agencies restrict the number and regulate the location of tobacco retailers as a means of reducing tobacco use. However, the best policy strategy for tobacco retailer reduction is unknown. The purpose of this study is to test the percent reduction in the number and density of tobacco retailers in North Carolina resulting from three policies: (1) prohibiting sales of tobacco products in pharmacies or stores with a pharmacy counter, (2) restricting sales of tobacco products within 1000 ft of schools, and (3) regulating to 500 ft the minimum allowable distance between tobacco outlets. This study uses data from two lists of tobacco retailers gathered in 2012, one at the statewide level, and another "gold standard" three-county list. Retailers near schools were identified using point and parcel boundaries in ArcMap. Python programming language generated a random lottery system to remove retailers within 500 ft of each other. Analyses were conducted in 2014. A minimum allowable distance policy had the single greatest impact and would reduce density by 22.1% at the state level, or 20.8% at the county level (range 16.6% to 27.9%). Both a pharmacy and near-schools ban together would reduce density by 29.3% at the state level, or 29.7% at the county level (range 26.3 to 35.6%). The implementation of policies restricting tobacco sales in pharmacies, near schools, and/or in close proximity to another tobacco retailer would substantially reduce the number and density of tobacco retail outlets.

Alrahlah, A; Silikas, N; Watts, D C

2014-02-01

To determine the post-cure depth of cure of bulk fill resin composites through using Vickers hardness profiles (VHN). Five bulk fill composite materials were examined: Tetric EvoCeram(®) Bulk Fill, X-tra base, Venus(®) Bulk Fill, Filtek™ Bulk Fill, SonicFill™. Three specimens of each material type were prepared in stainless steel molds which contained a slot of dimensions (15 mm × 4 mm × 2 mm), and a top plate. The molds were irradiated from one end. All specimens were stored at 37°C for 24h, before measurement. The Vickers hardness was measured as a function of depth of material, at 0.3mm intervals. Data were analysed by one-way ANOVA using Tukey post hoc tests (α=0.05). The maximum VHN ranged from 37.8 to 77.4, whilst the VHN at 80% of max.VHN ranged from 30.4 to 61.9. The depth corresponding to 80% of max.VHN, ranged from 4.14 to 5.03 mm. One-way ANOVA showed statistically significant differences between materials for all parameters tested. SonicFill exhibited the highest VHN (pFill the lowest (p≤0.001). SonicFill and Tetric EvoCeram Bulk Fill had the greatest depth of cure (5.03 and 4.47 mm, respectively) and was significant's different from X-tra base, Venus Bulk Fill and Filtek Bulk Fill (p≤0.016). Linear regression confirmed a positive regression between max.VHN and filler loading (r(2)=0.94). Bulk fill resin composites can be cured to an acceptable post-cure depth, according to the manufacturers' claims. SonicFill and Tetric EvoCeram Bulk Fill had the greatest depth of cure among the composites examined. Copyright © 2013 Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved.

Tobacco Industry Manipulation of Tobacco Excise and Tobacco Advertising Policies in the Czech Republic: An Analysis of Tobacco Industry Documents

Science.gov (United States)

Shirane, Risako; Smith, Katherine; Ross, Hana; Silver, Karin E.; Williams, Simon; Gilmore, Anna

2012-01-01

Background The Czech Republic has one of the poorest tobacco control records in Europe. This paper examines transnational tobacco companies' (TTCs') efforts to influence policy there, paying particular attention to excise policies, as high taxes are one of the most effective means of reducing tobacco consumption, and tax structures are an important aspect of TTC competitiveness. Methods and Findings TTC documents dating from 1989 to 2004/5 were retrieved from the Legacy Tobacco Documents Library website, analysed using a socio-historical approach, and triangulated with key informant interviews and secondary data. The documents demonstrate significant industry influence over tobacco control policy. Philip Morris (PM) ignored, overturned, and weakened various attempts to restrict tobacco advertising, promoting voluntary approaches as an alternative to binding legislation. PM and British American Tobacco (BAT) lobbied separately on tobacco tax structures, each seeking to implement the structure that benefitted its own brand portfolio over that of its competitors, and enjoying success in turn. On excise levels, the different companies took a far more collaborative approach, seeking to keep tobacco taxes low and specifically to prevent any large tax increases. Collective lobbying, using a variety of arguments, was successful in delaying the tax increases required via European Union accession. Contrary to industry arguments, data show that cigarettes became more affordable post-accession and that TTCs have taken advantage of low excise duties by raising prices. Interview data suggest that TTCs enjoy high-level political support and continue to actively attempt to influence policy. Conclusion There is clear evidence of past and ongoing TTC influence over tobacco advertising and excise policy. We conclude that this helps explain the country's weak tobacco control record. The findings suggest there is significant scope for tobacco tax increases in the Czech Republic and

Electron beam curing of coatings

International Nuclear Information System (INIS)

Schmidt, J.; Mai, H.

1986-01-01

Modern low-energy electron beam processors offer the possibility for high-speed curing of coatings on paper, plastics, wood and metal. Today the electron beam curing gets more importance due to the increasing environmental problems and the rising cost of energy. For an effective curing process low-energy electron beam processors as well as very reactive binders are necessary. Generally such binders consist of acrylic-modified unsaturated polyester resins, polyacrylates, urethane acrylates or epoxy acrylates and vinyl monomers, mostly multifunctional acrylates. First results on the production of EBC binders on the base of polyester resins and vinyl monomers are presented. The aim of our investigations is to obtain binders with curing doses ≤ 50 kGy. In order to reduce the curing dose we studied mixtures of resins and acrylates. (author)

2006-03-15

In general, an accelerated sulfur cure system consists of elemental sulfur, one or two cure accelerators, and cure activators. Crosslink density of a rubber vulcanizate determines the physical properties. By increasing the crosslink density, the modulus, hardness, resilience, and abrasion resistance increase, whereas the elongation at break, heat build-up, and stress relaxation decrease. Sulfur linkages are composed of monosulfide, disulfide, and polysulfides. Sulfur linkages, especially polysulfides, are dissociated by heating and this brings about decrease of the crosslink density.

Strength of Geopolymer Cement Curing at Ambient Temperature by Non-Oven Curing Approaches: An Overview

Science.gov (United States)

Wattanachai, Pitiwat; Suwan, Teewara

2017-06-01

At the present day, a concept of environmentally friendly construction materials has been intensively studying to reduce the amount of releasing greenhouse gases. Geopolymer is one of the cementitious binders which can be produced by utilising pozzolanic wastes (e.g. fly ash or furnace slag) and also receiving much more attention as a low-CO2 emission material. However, to achieve excellent mechanical properties, heat curing process is needed to apply to geopolymer cement in a range of temperature around 40 to 90°C. To consume less oven-curing energy and be more convenience in practical work, the study on geopolymer curing at ambient temperature (around 20 to 25°C) is therefore widely investigated. In this paper, a core review of factors and approaches for non-oven curing geopolymer has been summarised. The performance, in term of strength, of each non-oven curing method, is also presented and analysed. The main aim of this review paper is to gather the latest study of ambient temperature curing geopolymer and to enlarge a feasibility of non-oven curing geopolymer development. Also, to extend the directions of research work, some approaches or techniques can be combined or applied to the specific properties for in-field applications and embankment stabilization by using soil-cement column.

The American Society of Clinical Oncology (ASCO) supports the elimination of tobacco products. Toward that goal, ASCO urges the adoption of national policy that strengthens regulation of the sale, promotion, and distribution of such products. To reduce cancer mortality, our regulatory policies must recognize that the nicotine within tobacco is an addictive substance, the use of which leads to 30% of all cancer deaths and a total of 419,000 deaths each year. Tobacco-related advertising and promotion should be banned. At a minimum, national policies should: ban billboards; limit advertising to black and white text only; prohibit the sale or giveaway of products that contain tobacco brand names or logos; prohibit brand name sponsorship of sporting or entertainment events; and require stronger and more prominent warning labels on all tobacco products. Despite existing state laws prohibiting sale of tobacco products to minors, children are able to buy such products easily. National regulation of the sale and distribution of tobacco products is necessary to eliminate children's access to tobacco. Where sales are permitted, they should be limited to face-to-face purchases by individuals 18 and older. Vending machines and other means of distributing tobacco without a face-to-face purchase should be outlawed. To the extent tobacco sales are allowed to continue, the federal government should mandate that the tobacco industry contribute substantial funds for a national public education campaign to prevent young people from smoking and other tobacco use. ASCO has long advocated a substantial increase (in the range of $2) in the federal excise tax on cigarettes and other tobacco products- a measure known to decrease consumption, particularly among children. Revenue from a tax on tobacco products should be used to support retraining for tobacco farmers, biomedical research, health care delivery, and antitobacco education. United State trade policies should discourage the export

Computer Simulation of Cure Process of an Axisymmetric Rubber Article Reinforced by Metal Plates Using Extended ABAQUS Code

Full Text Available Afinite element model is developed for simulation of the curing process of a thick axisymmetric rubber article reinforced by metal plates during the molding and cooling stages. The model consists of the heat transfer equation and a newly developed kinetics model for the determination of the state of cure in the rubber. The latter is based on the modification of the well-known Kamal-Sourour model. The thermal contact of the rubber with metallic surfaces (inserts and molds and the variation of the thermal properties (conductivity and specific heat with temperature and state-of-cure are taken into consideration. The ABAQUS code is used in conjunction with an in-house developed user subroutine to solve the governing equations. Having compared temperature profile and variation of the state-of-cure with experimentally measured data, the accuracy and applicability of the model is confirmed. It is also shown that this model can be successfully used for the optimization of curing process which gives rise to reduction of the molding time.

Full Text Available As the most preventable cause of death in the world today, understanding tobacco use among one of the fastest growing ethnic/racial groups is warranted. We explore cigarette and smokeless tobacco (SLT use among South Asians in NJ and the Northeast using the Tobacco Use Supplement to the Current Population Survey. Overall, tobacco use rates among South Asians were similar or lower than the population. However, in NJ, South Asian males had the highest SLT rate (2.7% and in the Northeast, White (AOR = 5.8, 95%  CI = 3.7–9.4 and South Asian males (AOR = 4.0, 95%  CI = 1.5–10.6 had significantly higher odds of current SLT use relative to non-White males. Tobacco use among South Asians was not homogeneous; Pakistanis are overrepresented among cigarette smokers while Indians are overrepresented among SLT users. Given the differential tobacco use among and within South Asian, disaggregating data to understand tobacco use behaviors is necessary to develop effective interventions for tobacco cessation.

Aim: The aim of this study is to compare and to evaluate effect of curing light and curing modes on the nanohybrid composite resins with conventional Bis-GMA and novel tricyclodecane (TCD) monomers. Methodology: Two nanohybrid composites, IPS empress direct and charisma diamond were used in this study. Light-emitting diode (LED)-curing unit and quartz-tungsten-halogen (QTH)-curing unit which were operated into two different modes: continuous and soft start. Based on the composite resin, curing lights, and mode of curing used, the samples were divided into 8 groups. After polymerization, the samples were stored for 48 h in complete darkness at 37°C and 100% humidity. The Vickers hardness (VK) of the surface was determined with Vickers indenter by the application of 200 g for 15 s. Three VK readings were recorded for each sample surface both on top and bottom surfaces. For all the specimens, the three hardness values for each surface were averaged and reported as a single value. The mean VK and hardness ratio were calculated. The depth of cure was assessed based on the hardness ratio. Results: Comparison of mean hardness values and hardness ratios was done using ANOVA with post hoc Tukey's test. Conclusion: Both QTH- and LED-curing units had shown the adequate depth of cure. Soft-start-curing mode in both QTH- and LED-curing lights had effectively increased microhardness than the continuous mode of curing. TCD monomer had shown higher hardness values compared with conventional Bis-GMA-containing resin. PMID:29628651

The opium wars revisited as US forces tobacco exports in Asia.

Science.gov (United States)

Chen, T T; Winder, A E

1990-01-01

The tobacco industry has lobbied successfully to obtain the support of the United States government for opening Asian Markets to American tobacco products. This paper comments on two issues arising from these efforts: the development of an atmosphere of invasion and resistance to invasion in Asia; and the change in the image of the United States in Asian nations from that of a leader in health to that of an exporter of death. The threat of sanctions and the effects of the open market and United States tobacco company advertising in Japan, Taiwan, and South Korea are noted. Parallels are drawn between the opium wars a century and a half ago in China and the current threat of trade sanctions. Reacting to American policy, an Asia-Pacific Association for Control of Tobacco has been formed and linked with the US Coalition Against Smoking. PMID:2343946

Kinetic studies of chemical shrinkage and residual stress formation in thermoset epoxy adhesives under confined curing conditions

Science.gov (United States)

Schumann, M.; Geiß, P. L.

2015-05-01

Faultless processing of thermoset polymers in demanding applications requires a profound mastering of the curing kinetics considering both the physico-chemical changes in the transition from the liquid to the solid state and the consolidation of the polymers network in the diffusion controlled curing regime past the gel point. Especially in adhesive joints shrinkage stress occurring at an early state of the curing process under confined conditions is likely to cause defects due to local debonding and thus reduce their strength and durability1. Rheometry is considered the method of choice to investigate the change of elastic and viscous properties in the progress of curing. Drawbacks however relate to experimental challenges in accessing the full range of kinetic parameters of thermoset resins with low initial viscosity from the very beginning of the curing reaction to the post-cure consolidation of the polymer due to the formation of secondary chemical bonds. Therefore the scope of this study was to interrelate rheological data with results from in-situ measurements of the shrinkage stress formation in adhesive joints and with the change of refractive index in the progress of curing. This combination of different methods has shown to be valuable in gaining advanced insight into the kinetics of the curing reaction. The experimental results are based on a multi component thermoset epoxy-amine adhesive.

In 2015, 27.8% of adult Medicaid enrollees were current cigarette smokers, compared with 11.1% of adults with private health insurance, placing Medicaid enrollees at increased risk for smoking-related disease and death (1). In addition, smoking-related diseases are a major contributor to Medicaid costs, accounting for about 15% (>$39 billion) of annual Medicaid spending during 2006-2010 (2). Individual, group, and telephone counseling and seven Food and Drug Administration (FDA)-approved medications are effective treatments for helping tobacco users quit (3). Insurance coverage for tobacco cessation treatments is associated with increased quit attempts, use of cessation treatments, and successful smoking cessation (3); this coverage has the potential to reduce Medicaid costs (4). However, barriers such as requiring copayments and prior authorization for treatment can impede access to cessation treatments (3,5). As of July 1, 2016, 32 states (including the District of Columbia) have expanded Medicaid eligibility through the Patient Protection and Affordable Care Act (ACA),* ,† which has increased access to health care services, including cessation treatments (5). CDC used data from the Centers for Medicare and Medicaid Services (CMS) Medicaid Budget and Expenditure System (MBES) and the Behavioral Risk Factor Surveillance System (BRFSS) to estimate the number of adult smokers enrolled in Medicaid expansion coverage. To assess cessation coverage among Medicaid expansion enrollees, the American Lung Association collected data on coverage of, and barriers to accessing, evidence-based cessation treatments. As of December 2015, approximately 2.3 million adult smokers were newly enrolled in Medicaid because of Medicaid expansion. As of July 1, 2016, all 32 states that have expanded Medicaid eligibility under ACA covered some cessation treatments for all Medicaid expansion enrollees, with nine states covering all nine cessation treatments for all Medicaid expansion

Vatican beats Italy 1-0 in the tobacco endgame.

'The Holy See cannot be cooperating with a practice that is clearly harming the health of people'. This is the reason behind Pope Francis banning the sale of tobacco products inside the Vatican in January 2018. Just outside the Holy See, in Italy, cigarette sales produce around €13 billion of fiscal revenues every year. In Italy, proposals to increase tobacco taxation are systematically rejected and new tobacco company plants have been officially inaugurated in recent years by representatives of State. The national branch of the Red Cross also shows ambivalent attitudes towards the tobacco industry, from which it has accepted significant funding in disregard of the recommendations of the International Federation of Red Cross. Against this backdrop, it is wishful thinking to imagine that tobacco sales and consumption in Italy will be substantially reduced in the near future. To counteract this situation, more than 30 Italian scientific associations/organisations launched a Manifesto, so far ignored by public authorities, indicating a set of measures whose gradual implementation at country level may lead to a tobacco endgame within the next few decades. Authors of this article would like to express their support for Pope Francis' enlightened decision and plead with politicians worldwide to follow his example, thus acting more decisively against tobacco. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Polytobacco Use and the "Customization Generation"-New Perspectives for Tobacco Control.

Science.gov (United States)

Horn, Kimberly; Pearson, Jennifer L; Villanti, Andrea C

2016-12-01

In recent years, the United States observed a significant uptake in concurrent use of multiple tobacco products and alternative nicotine delivery devices among youth-a phenomenon identified as polytobacco use-making tobacco control efforts more complex for clinicians, policy makers, and scientists, alike.The present commentary stimulates new perspectives on tobacco control in the context of polytobacco use and a youth culture of customization. This culture-based value of today's youth may inform current patterns of tobacco use. More specifically, the authors hypothesize a concept of tobacco customization-the concurrent use of multiple tobacco products to create personalized tobacco experience matching lifestyle, culture, values, and addiction levels. With a range of experiences made possible through an ever-increasing menu of tobacco products, flavors, and novel devices, the current youth culture of customization may also translate to tobacco customization. Given the predominance of polytobacco use in youth-tobacco users, tobacco control initiatives must be challenged to new perspectives. Should we discover the viability of tobacco customization, tobacco use strategies that target cultural values, harness popular trends, and culture and provide customizable experiences may have a notable impact on tobacco use in this population.

The International Monetary Fund and tobacco: a product like any other?

Science.gov (United States)

Gilmore, Anna; Fooks, Gary; McKee, Martin

2009-01-01

The International Monetary Fund (IMF) has promoted the lifting of trade restrictions on tobacco and the privatization of state-owned tobacco industries as part of its loan conditions. Growing evidence shows that tobacco industry privatization stimulates tobacco consumption and smoking prevalence in borrowing countries. Privatized tobacco companies make favorable tobacco control policies a condition of their investment and lobby aggressively against further control measures. This, along with increased efficiency of the private sector, leads to increases in marketing, substantial reductions in excise taxes, drops in cigarette prices, and overall rises in sales of cigarettes. The actions of the IMF have therefore led to substantially greater use of tobacco, a product that kills half of its consumers when used as intended, with little evidence of economic gain.

Tobacco tax and the illicit trade in tobacco products in New Zealand.

Ajmal, Ali; U, Veng Ian

2015-04-01

To estimate the size of illegal tobacco trade and consumption and assess the impact of tobacco tax on the illicit tobacco market in New Zealand (NZ). Data on the import and seizure of legal and illegal tobacco in NZ was obtained from NZ Customs. Previous literature was used to calculate interception rates of illegal tobacco being smuggled and grown in NZ. Annual tobacco returns figures, obtained via the NZ Ministry of Health, were analysed to assess the market dynamics of legal tobacco products. This study found that illicit tobacco constituted 1.8-3.9% of total national tobacco consumption in NZ in 2013. This represents a minor increase compared to previous estimates from 2007-09, suggesting that tax increases enacted by the NZ Government since 2010 have had a minimal impact on encouraging the use and procurement of illicit tobacco. The results highlight a slight rise in small-scale tobacco smuggling through ports and mail centres. However, tobacco returns figures show that current tobacco tax policy has forced manufacturers to focus on the production of cheap legal tobacco products, directly competing with and undercutting the demand for illicit tobacco products. At the same time, locally grown illicit tobacco continues to remain a small, isolated problem and, with recent cuts in duty free tobacco allowance, it is expected that overall illicit tobacco will remain a very small proportion of total tobacco consumption in NZ. © 2015 Public Health Association of Australia.

The Case for Requiring Graphic Warning Labels on Smokeless Tobacco Product Packages.

Pakhale, Smita; Samet, Jonathan; Folan, Patricia; Leone, Frank; White, Alexander

2016-03-01

On November 10, 2015, the U.S. Food and Drug Administration approved, for the first time, the sale of smokeless tobacco products authorized under the new premarket tobacco application pathway. This Food and Drug Administration regulatory decision draws attention to the growing worldwide use of smokeless tobacco products in general. Use of these tobacco products is particularly popular in low- and middle-income countries of Asia. Due to aggressive and strategic marketing to children, young adults, and current smokers, rates of smokeless tobacco use in men of all ages are on the rise in United States and elsewhere. The tobacco industry also continues to market these products to current cigarette smokers for use in the growing number of "smoke-free environments." Smokeless tobacco products are associated with cancers of the upper aerodigestive tract, particularly the oral cavity, esophagus, and pancreas; cardiovascular diseases; small-for-gestational-age infants; premature births; increased risk of apnea; and stillbirth. There is no convincing evidence regarding the efficacy of smokeless tobacco, including snus, to promote smoking cessation. Rather, studies from Europe and the United States demonstrate that smokeless tobacco use may facilitate regular cigarette smoking by acting as a gateway drug, especially for children. Caution is warranted before proposing smokeless tobacco as a harm-reduction strategy, in part because of the potential for further promoting smokeless tobacco in low- and middle-income countries where use is already widespread. Continued vigilance through comprehensive surveillance is warranted. We strongly recommend the use of graphic warning labels as a "no regrets" strategy for all smokeless tobacco products marketed globally.

To assesses the statistical association between exposure to tobacco marketing and tobacco consumption among adolescents in South America, by using data from the Global Youth Tobacco Survey. Using data from the Global Youth Tobacco Survey (GYTS), the exposure to tobacco marketing at the school level was studied from advertising in TV, radio, massive public events and street advertisement. Tobacco behaviour was considered. The total pooled sample used was 134 073 youths from Argentina, Bolivia, Chile, Peru, Brazil, Uruguay, Suriname, Colombia, Guyana, Ecuador, Paraguay and Venezuela. The exposure to tobacco marketing is positively and significantly associated to the probability of youths experimenting with tobacco (at least once in their lifetime). For regular smokers, exposure to tobacco marketing is positively and significantly associated to smoking intensity. These results call for the implementation of strong restrictions on tobacco advertisement of various types in South American countries.

Cure monitoring can be used to improve the quality and productivity of thermosetting resin matrix composite products during their manufacturing process. In this work, the sensitivity of dielectrometry was improved by adequate separation the efforts of sensor and externals on the measured signal. A new algorithm to obtain the degree of cure during dielectric cure monitoring of glass/polyester and glass/epoxy composites was developed by employing a function of both temperature and dissipation factor, in which five cure monitoring parameters were used to calculate the degree of cure. The decreasing pattern of dissipation factor was compared with the relationships between the degree of cure and the resin viscosity. The developed algorithm might be employed for the in situ cure monitoring of thermosetting resin composites

From the American Academy of Pediatrics: Policy statement--Tobacco use: a pediatric disease.

Science.gov (United States)

2009-11-01

Tobacco use and secondhand tobacco-smoke (SHS) exposure are major national and international health concerns. Pediatricians and other clinicians who care for children are uniquely positioned to assist patients and families with tobacco-use prevention and treatment. Understanding the nature and extent of tobacco use and SHS exposure is an essential first step toward the goal of eliminating tobacco use and its consequences in the pediatric population. The next steps include counseling patients and family members to avoid SHS exposures or cease tobacco use; advocacy for policies that protect children from SHS exposure; and elimination of tobacco use in the media, public places, and homes. Three overarching principles of this policy can be identified: (1) there is no safe way to use tobacco; (2) there is no safe level or duration of exposure to SHS; and (3) the financial and political power of individuals, organizations, and government should be used to support tobacco control. Pediatricians are advised not to smoke or use tobacco; to make their homes, cars, and workplaces tobacco free; to consider tobacco control when making personal and professional decisions; to support and advocate for comprehensive tobacco control; and to advise parents and patients not to start using tobacco or to quit if they are already using tobacco. Prohibiting both tobacco advertising and the use of tobacco products in the media is recommended. Recommendations for eliminating SHS exposure and reducing tobacco use include attaining universal (1) smoke-free home, car, school, work, and play environments, both inside and outside, (2) treatment of tobacco use and dependence through employer, insurance, state, and federal supports, (3) implementation and enforcement of evidence-based tobacco-control measures in local, state, national, and international jurisdictions, and (4) financial and systems support for training in and research of effective ways to prevent and treat tobacco use and SHS

Smokeless tobacco products sold in the United States vary significantly in yields of nicotine and tobacco-specific nitrosamines (TSNA). With the passage of the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration now has the authority to establish product standards. However, limited data exist determining the relative roles of pattern of smokeless tobacco use versus constituent levels in the smokeless tobacco product in exposure of users to carcinogens. In this study, smokeless tobacco users of brands varying in nicotine and TSNA content were recruited from three different regions in the U.S. Participants underwent two assessment sessions. During these sessions, demographic and smokeless tobacco use history information along with urine samples to assess biomarkers of exposure and effect were collected. During the time between data collection, smokeless tobacco users recorded the amount and duration of smokeless tobacco use on a daily basis using their diary cards. Results showed that independent of pattern of smokeless tobacco use and nicotine yields, levels of TSNA in smokeless tobacco products played a significant role in carcinogen exposure levels. Product standards for reducing levels of TSNA in smokeless tobacco products are necessary to decrease exposure to these toxicants and potentially to reduce risk for cancer. ©2014 American Association for Cancer Research.

Tobacco point-of-purchase promotion: examining tobacco industry documents.

Lavack, Anne M; Toth, Graham

2006-10-01

In the face of increasing media restrictions around the world, point-of-purchase promotion (also called point-of-sale merchandising, and frequently abbreviated as POP or POS) is now one of the most important tools that tobacco companies have for promoting tobacco products. Using tobacco industry documents, this paper demonstrates that tobacco companies have used point-of-purchase promotion in response to real or anticipated advertising restrictions. Their goal was to secure dominance in the retail setting, and this was achieved through well-trained sales representatives who offered contracts for promotional incentive programmes to retailers, which included the use of point-of-sale displays and merchandising fixtures. Audit programmes played an important role in ensuring contract enforcement and compliance with a variety of tobacco company incentive programmes. Tobacco companies celebrated their merchandising successes, in recognition of the stiff competition that existed among tobacco companies for valuable retail display space.

'Manage and mitigate punitive regulatory measures, enhance the corporate image, influence public policy': industry efforts to shape understanding of tobacco-attributable deforestation.

Lee, Kelley; Carrillo Botero, Natalia; Novotny, Thomas

2016-09-20

Deforestation due to tobacco farming began to raise concerns in the mid 1970s. Over the next 40 years, tobacco growing increased significantly and shifted markedly to low- and middle-income countries. The percentage of deforestation caused by tobacco farming reached 4 % globally by the early 2000s, although substantially higher in countries such as China (18 %), Zimbabwe (20 %), Malawi (26 %) and Bangladesh (>30 %). Transnational tobacco companies (TTCs) have argued that tobacco-attributable deforestation is not a serious problem, and that the industry has addressed the issue through corporate social responsibility (CSR) initiatives. After reviewing the existing scholarly literature on tobacco and deforestation, we analysed industry sources of public information to understand how the industry framed deforestation, its key causes, and policy responses. To analyse industry strategies between the 1970s and early 2000s to shape understanding of deforestation caused by tobacco farming and curing, the Truth Tobacco Documents Library was systematically searched. The above sources were compiled and triangulated, thematically and chronologically, to derive a narrative of how the industry has framed the problem of, and solutions to, tobacco-attributable deforestation. The industry sought to undermine responses to tobacco-attributable deforestation by emphasising the economic benefits of production in LMICs, blaming alternative causes, and claiming successful forestation efforts. To support these tactics, the industry lobbied at the national and international levels, commissioned research, and colluded through front groups. There was a lack of effective action to address tobacco-attributable deforestation, and indeed an escalation of the problem, during this period. The findings suggest the need for independent data on the varied environmental impacts of the tobacco industry, awareness of how the industry seeks to work with environmental researchers and groups to

An overarching goal of Healthy People 2020 is to achieve health equity, eliminate disparities, and improve health among all groups.* Although significant progress has been made in reducing overall commercial tobacco product use, † disparities persist, with American Indians or Alaska Natives (AI/ANs) having one of the highest prevalences of cigarette smoking among all racial/ethnic groups (1,2). Variations in cigarette smoking among AI/ANs have been documented by sex and geographic location (3), but not by other sociodemographic characteristics. Furthermore, few data exist on use of tobacco products other than cigarettes among AI/ANs (4). CDC analyzed self-reported current (past 30-day) use of five tobacco product types among AI/AN adults from the 2010-2015 National Survey on Drug Use and Health (NSDUH); results were compared with six other racial/ethnic groups (Hispanic; non-Hispanic white [white]; non-Hispanic black [black]; non-Hispanic Native Hawaiian or other Pacific Islander [NHOPI]; non-Hispanic Asian [Asian]; and non-Hispanic multirace [multirace]). Prevalence of current tobacco product use was significantly higher among AI/ANs than among non-AI/ANs combined for any tobacco product, cigarettes, roll-your-own tobacco, pipes, and smokeless tobacco. Among AI/ANs, prevalence of current use of any tobacco product was higher among males, persons aged 18-25 years, those with less than a high school diploma, those with annual family income product use and eliminate disparities in tobacco product use among AI/ANs (1).

Tobacco Product Waste: An Environmental Approach to Reduce Tobacco Consumption.

Cigarette butts and other tobacco product wastes (TPW) are the most common items picked up in urban and beach cleanups worldwide. TPW contains all the toxins, nicotine, and carcinogens found in tobacco products, along with the plastic nonbiodegradable filter attached to almost all cigarettes sold in the United States and in most countries worldwide. Toxicity studies suggest that compounds leached from cigarette butts in salt and fresh water are toxic to aquatic micro-organisms and test fish. Toxic chemicals have also been identified in roadside TPW. With as much as two-thirds of all smoked cigarettes (numbering in the trillions globally) being discarded into the environment each year, it is critical to consider the potential toxicity and remediation of these waste products. This article reviews reports on the toxicity of TPW and recommends several policy approaches to mitigation of this ubiquitous environmental blight.

Radiation curing of coatings of wood based products is expanding and being used for curing of coatings of table tops, parquet, wood panel, furniture, curtain railing, etc. UV curing of over print varnish is still the main application of UV curing in printing industry. However, curing of printing ink has also been extended in the printing of CD and VCD in addition to other printing such as paper, magazine, label on bottles, metal-can, etc. In the electronic industry, the manufacturer of printed circuit board is still the main consumer of UV curable resins. On the other hand, low energy electron beam machine is used mainly for cross-linking of heat shrink films

Background Debate about the health implications of using smokeless tobacco products (STPs) has prompted considerable interest in characterising their levels of toxic and carcinogenic components. In the present study seventy smokeless tobacco products from the US and Sweden, categorized as chewing tobacco, dry and moist snuff, hard and soft pellets, plug, and loose and portion snus, were analysed for twenty one polycyclic aromatic hydrocarbons (PAHs). The tested brands represented 80-90% of the 2008 market share for the major STP categories in these two countries. Results There were significant differences in the total and individual PAH concentrations in the different styles of product. Substantially higher levels of total PAHs (10–60 fold) were found in moist and dry snuff and soft pellets than in the other smokeless tobacco styles. The individual PAH concentrations followed the same patterns as total PAHs except for naphthalene, for which the highest concentrations were found in snus and moist snuff. Good correlations were obtained between benzo[a]pyrene (B[a]P) and all the other PAHs except naphthalene, 1-methylnaphthalene and 2-methylnaphthalene, providing evidence for the first time that it can be used as a good marker for PAHs in STPs. Results were generally in good agreement with two previous studies of PAHs in STPs, except for naphthalene for which significantly lower concentrations were found than previously reported. Analysis of the ratios of different PAHs confirmed that the use of fire-cured tobaccos in the snuffs and soft pellet were the major source of PAHs in these product styles, and provided, for the first time, some indications as to the source of PAHs in the other STP styles, including petrogenic and other combustion sources. Conclusions This study confirms the presence of PAHs in STPs, and identifies substantial differences between the levels in different STP categories. Since previous studies of naphthalene concentrations in STPs differed so

Full Text Available Objective. To assesses the statistical association between exposure to tobacco marketing and tobacco consumption among adolescents in South America, by using data from the Global Youth Tobacco Survey. Materials and methods. Using data from the Global Youth Tobacco Survey (GYTS, the exposure to tobacco marketing at the school level was studied from advertising in TV, radio, massive public events and street advertisement. Tobacco behaviour was considered. The total pooled sample used was 134 073 youths from Argentina, Bolivia, Chile, Peru, Brazil, Uruguay, Suriname, Colombia, Guyana, Ecuador, Paraguay and Venezuela. Results. The exposure to tobacco marketing is positively and significantly associated to the probability of youths experimenting with tobacco (at least once in their lifetime. For regular smokers, exposure to tobacco marketing is positively and significantly associated to smoking intensity. Conclusions. These results call for the implementation of strong restrictions on tobacco advertisement of various types in South American countries.

Scholars who examine the efficacy of juvenile tobacco sales restrictions, especially the 1992 "Synar Amendment" that led all of fifty U.S. states to enact prohibitions on tobacco sales to minors, are notably divided as to impact on youth smoking. Some researchers claim that such policies have failed and ought to be abandoned (Craig & Boris, 2007; Etter, 2006; Glantz, 2002), while others insist that enforcement has indeed led to reduced tobacco use (DiFranza, 2011b; SAMHSA, 2011). The present study is the first to combine data on Synar violation rates from all states and years available since the amendment's implementation, assessing the connection to national rates of cigarette sales and youth smoking behavior. Using national data from the United States Substance Abuse and Mental Health Services Administration, the Tobacco Institute, and the Centers for Disease Control's Youth Risk Behavior Surveillance System across all U.S. states between 1996 and 2007, we employ hierarchical linear modeling to examine the connection between retailer Synar violations and youth smoking. Controlling for state-level demographic variables, results indicate that retailer violation rates are significantly associated with greater youth smoking prevalence, as well as higher overall cigarette sales. While critiques of Synar policies are substantive and should be addressed, laws prohibiting the sale of tobacco to juveniles appear to have had some degree of success. Copyright © 2015 Elsevier B.V.

Tobacco-related content appears on social media in the form of advertising and messages by individuals. However, little is known about associations between posting social media messages and tobacco product use among adolescents and young adults. Self-reports of tobacco product use were obtained from the Children's Health Study of young adults in Southern California. Among the 1486 respondents in the most recent wave of the cohort (2016-2017), 284 provided tobacco product use data and their Twitter user names to access publicly available Twitter account data (mean age = 20.1 yrs. (SD = 0.6), 54% female, 49% Hispanic). We obtained the tweets that those respondents posted on Twitter, searched the tweets for 14 nicotine- and tobacco-related keywords, and coded these statements as positive or negative/neutral. Logistic regression analyses were conducted to determine whether respondents who posted positive tobacco-related tweets were more likely to report tobacco product use, relative to those who did not post any positive tobacco-related tweets. Respondents who posted any positive messages about tobacco had significantly higher odds of reporting past month use of cigarettes (OR = 3.15, 95% CI = 1.36, 7.30) and any tobacco product (OR = 2.41, 95% CI = 1.16, 5.01), relative to respondents who did not post about tobacco. This is the first study to establish an empirical link between adolescents' and young adults' tobacco-related Twitter activity and their tobacco product use. Health communications about the risks of tobacco use could target adolescents who post positive messages about tobacco products on Twitter. Copyright © 2018 Elsevier Inc. All rights reserved.

Non-cigarette tobacco marketing is less regulated and may promote cigarette smoking among adolescents. We quantified receptivity to advertising for multiple tobacco products and hypothesized associations with susceptibility to cigarette smoking. Wave 1 of the nationally representative PATH (Population Assessment of Tobacco and Health) study interviewed 10 751 adolescents who had never used tobacco. A stratified random selection of 5 advertisements for each of cigarettes, e-cigarettes, smokeless products, and cigars were shown from 959 recent tobacco advertisements. Aided recall was classified as low receptivity, and image-liking or favorite ad as higher receptivity. The main dependent variable was susceptibility to cigarette smoking. Among US youth, 41% of 12 to 13 year olds and half of older adolescents were receptive to at least 1 tobacco advertisement. Across each age group, receptivity to advertising was highest for e-cigarettes (28%-33%) followed by cigarettes (22%-25%), smokeless tobacco (15%-21%), and cigars (8%-13%). E-cigarette ads shown on television had the highest recall. Among cigarette-susceptible adolescents, receptivity to e-cigarette advertising (39.7%; 95% confidence interval [CI]: 37.9%-41.6%) was higher than for cigarette advertising (31.7%; 95% CI: 29.9%-33.6%). Receptivity to advertising for each tobacco product was associated with increased susceptibility to cigarette smoking, with no significant difference across products (similar odds for both cigarette and e-cigarette advertising; adjusted odds ratio = 1.22; 95% CI: 1.09-1.37). A large proportion of US adolescent never tobacco users are receptive to tobacco advertising, with television advertising for e-cigarettes having the highest recall. Receptivity to advertising for each non-cigarette tobacco product was associated with susceptibility to smoke cigarettes. Copyright © 2017 by the American Academy of Pediatrics.

Purpose We examined the influence of tobacco control program funding, smoke-free air laws, and cigarette prices on young adult smoking outcomes. Methods We use a natural experimental design approach that uses the variation in tobacco control policies across states and over time to understand their influence on tobacco outcomes. We combine individual outcome data with annual state-level policy data to conduct multivariable logistic regression models, controlling for an extensive set of sociodemographic factors. The participants are 18- to 25-year-olds from the 2002–2009 National Surveys on Drug Use and Health. The three main outcomes are past-year smoking initiation, and current and established smoking. A current smoker was one who had smoked on at least 1 day in the past 30 days. An established smoker was one who had smoked 1 or more cigarettes in the past 30 days and smoked at least 100 cigarettes in his or her lifetime. Results Higher levels of tobacco control program funding and greater smoke-free-air law coverage were both associated with declines in current and established smoking (p smoke-free air laws was associated with lower past year initiation with marginal significance (p = .058). Higher cigarette prices were not associated with smoking outcomes. Had smoke-free-air law coverage and cumulative tobacco control funding remained at 2002 levels, current and established smoking would have been 5%–7% higher in 2009. Conclusions Smoke-free air laws and state tobacco control programs are effective strategies for curbing young adult smoking. PMID:24268360

Thermal curing of epoxy resin requires high temperature, time-consuming process and the volatilization of hardener. It has known that electron beam curing of epoxy resin is a fast process and occurs at low or room temperature that help reduce residual mechanical stresses in thermosetting polymers. Diepoxidized cardanol (DEC) can be synthesized by an enzymatic method from cashew nut shell liquid (CNSL), that constitutes nearly one-third of the total nut weight. A large amount of CNSL can be formed as a byproduct of the mechanical processes used to render the cashew kerneledible and its total production approaches one million tons annually, which can be bio-degradable and replace the industrial thermosetting plastics. It is expected that DEC may be cured as in an epoxy resin, which was constituted on two epoxide group and long alkyl chain, and two-types of onium salts (cationic initiator) were used as a photo-initiator. The experimental variables of this study are type and concentration of photo-initiators and electron beam dosage. In this study, the effects of initiator type and concentration on the cure behavior and the thermal properties of DEC resin processed by using electron beam technology were studied using FT-IR, TGA, TMA, DSC, and DMA. Figure 1 is the FT-IR results, showing the change of chemical structure of pure DEC and electron beam cured DEC. The characteristic absorption peak of epoxide group appeared at 850cm -1 . The shape and the height were reduced when the sample was irradiated with electron beam. From this result, the epoxide groups is DEC were opened by electron beam and cured. After then, electron beam cured DEC was investigated the effect of forming 3-dimensional network

Since the special tobacco tax was established in 1998, the tobacco tax and price of tobacco have increased thrice, in 2003, 2006, and 2010, respectively. We evaluated the effect of increases in tax on the consumption and sales of tobacco in Japan using the annual data on the number of tobacco products sold and the total sales from Japan Tobacco, Inc. We applied the number of tobacco products sold and the total sales per year to a joinpoint regression model to examine the trends in the data. This model could help identify the year in which a decrease or increase was apparent from the data. In addition, we examined the effect of each tax increase while also considering other factors that may have caused a decrease in the levels of tobacco consumption using the method proposed by Hirano et al. According to the joinpoint regression analysis, the number of tobacco products sold started decreasing in 1998, and the trends of decrease accelerated to 5% per year, from 2005. Owing to the tax increase, tobacco sales reduced by -2.4%, -2.9%, and -10.1% (corrected for the effect of the Tohoku Great Earthquake), and price elasticity was estimated as -0.30, -0.27, and -0.28 (corrected) in 2003, 2006, and 2010, respectively. The effect of tobacco tax increase on the decrease in tobacco sales was greatest in 2010, while the price elasticity remained almost the same as it was during the previous tax increase. The sharp hike in tobacco tax in 2010 decreased the number of tobacco products sold, while the price elasticity in 2010 was similar to that in 2003 and 2006. Our findings suggest that further increase in tobacco tax is needed to reduce the damage caused by smoking in the people of Japan.

Businesses changing their practices in ways that support tobacco control efforts recently have gained interest, as demonstrated by CVS Health's voluntary policy to end tobacco sales. Point-of-sale (POS) advertisements are associated with youth smoking initiation, increased tobacco consumption, and reduced quit attempts among smokers. There is interest in encouraging retailers to limit tobacco POS advertisements voluntarily. This qualitative exploratory study describes Oklahoma tobacco retailers' perspectives on a mutual benefit exchange approach, and preferred message and messenger qualities that would entice them to take voluntary action to limit tobacco POS advertisements. This study found that mutual benefit exchange could be a viable option along with education and law as strategies to create behavior change among tobacco retailers. Many retailers stated that they would be willing to remove noncontractual POS advertisements for a 6-month commitment period when presented with mutual exchange benefit, tailored message, and appropriate messenger. Mutual benefit exchange, as a behavior change strategy to encourage voluntary removal of POS tobacco advertisements, was acceptable to retailers, could enhance local tobacco control in states with preemption, and may contribute to setting the foundation for broader legislative efforts. © 2015 Society for Public Health Education.

In order to sustain their market, tobacco producers target young adults through novel product design and marketing strategies. Public health professionals need to understand young adults' risks perceptions about and use of new tobacco products to best inform tobacco control interventions. In 2009, researchers conducted 8 focus groups with 67 young adults stratified by self-reported tobacco use and nonuse, residence in rural and urban areas, and living in a state with or without a statewide smoking restriction policy. Participants provided feedback about their knowledge and risk perceptions about and use of tobacco products and marketing. Participants reported a high level of familiarity with a wide range of novel tobacco products. A great deal of confusion and disagreement appeared with regard to absolute and relative risk of different tobacco products. Participants readily discussed using smokeless tobacco products as alternatives to smoking when smoking is prohibited. Fewer differences in tobacco-related knowledge risk perceptions and use were found between urban and rural participants and those in smoke-free policy and nonpolicy states than between user and nonuser groups. Both users and nonusers were familiar with and skeptical about tobacco marketing and prevention efforts. Young adults are familiar with many tobacco products, but they convey little understanding of relative risks of new or trendy tobacco products, such as snus or hookah. Mindful of industry innovation, tobacco control advocates must continuously update prevention efforts, seeking new strategies to limit promotion, marketing, and use of new and conventional products.
