ABSTRACT
OBJECTIVES: To examine the associations among cigarette design features and tar yields of leading cigarette brands sold in the United States, Canada, Australia and the United Kingdom. METHODS: Government reports and numbers listed on packs were used to obtain data on International Organization for Standardization (ISO)/Federal Trade Commission (FTC) yields for the tar of 172 cigarette varieties sold in the United States, Canada, Australia and the United Kingdom. We used standardised methods to measure the following 11 cigarette design parameters: filter ventilation, cigarette pressure drop, filter pressure drop, tobacco rod length, filter length, cigarette diameter, tipping paper length, tobacco weight, filter weight, rod density and filter density. RESULTS: Filter ventilation was found to be the predominant design feature accounting for the variations between brands in ISO/FTC tar yields in each of the four countries. After accounting for filter ventilation, design parameters such as overwrap length, tobacco weight and rod density played comparatively minor roles in determining tar yields. CONCLUSIONS: Variation in ISO/FTC tar yields are predicted by a limited set of cigarette design features, especially filter ventilation, suggesting that governments should consider mandatory disclosure of cigarette design parameters as part of comprehensive tobacco product regulations.

This paper describes the conceptual model that underlies the International Tobacco Control Policy Evaluation Project (ITC Project), whose mission is to measure the psychosocial and behavioural impact of key policies of the Framework Convention on Tobacco Control (FCTC) among adult smokers, and in some countries, among adult non-smokers and among youth. The evaluation framework utilises multiple country controls, a longitudinal design, and a pre-specified, theory-driven conceptual model to test hypotheses about the anticipated effects of specific policies. The ITC Project consists of parallel prospective cohort surveys of representative samples of adult smokers currently in nine countries (inhabited by over 45% of the world's smokers), with other countries being added in the future. Collectively, the ITC Surveys constitute the first-ever international cohort study of tobacco use. The conceptual model of the ITC Project draws on the psychosocial and health communication literature and assumes that tobacco control policies influence tobacco related behaviours through a causal chain of psychological events, with some variables more closely related to the policy itself (policy-specific variables) and other variables that are more downstream from the policy, which have been identified by health behaviour and social psychological theories as being important causal precursors of behaviour (psychosocial mediators). We discuss the objectives of the ITC Project and its potential for building the evidence base for the FCTC.

Filter ventilation is the dominant design feature of the modern cigarette that determines yields of tar, nicotine, and carbon monoxide on smoking machine tests. The commercial use of filter ventilation was precipitated by the 1964 United States Surgeon-General's report, further advanced by the adoption of an official Federal Trade Commission test in 1967, and still further advanced by the inclusion of a gas phase (carbon monoxide) measure in 1979. The first vented-filter brand on the market in the United States (Carlton) in 1964 and the second major vented-filter brand (True) in 1966 illustrate this. Ultimately, filter ventilation became a virtually required way to make very low tar cigarettes (less than 10 mg or, even more so, less than 5 mg tar). The key to the lower tar cigarette was not, in effect, the advanced selective filtration design characteristics or sophisticated tobacco selection or processing as envisioned by experts (although these techniques were and are used); the key to the very much lower tar cigarette was simply punching holes in the filter. We propose that the banning of filter vents, coupled with low maximum standard tar, nicotine, and carbon monoxide yields, would contribute to making cigarettes much less palatable and foster smoking cessation or the use of clearly less hazardous nicotine delivery systems. It may be necessary to link low maximum yields with the banning of filter ventilation to achieve public health benefit from such maxima.

BACKGROUND: On 28 June 2004, New York State (NY) became the first jurisdiction to require cigarettes to meet a reduced ignition propensity (RIP) standard. This law resulted in cigarette manufacturers modifying nearly all of their brands sold in NY. However, the same cigarette brands sold in other states were not modified to meet the RIP standard. OBJECTIVES: This paper examines relationships between the RIP law and smokers' awareness of changes in the performance of their cigarettes (that is, going out more frequently, change in taste), and smoking behaviour. METHODS: Data for this analysis come from a nationwide survey of 2088 adult smokers (> 18 years of age) conducted in the USA between July and December 2004. 143 of the smokers included in the survey were residents of NY while the remainder were from other states (n = 1945). Survey participants were asked whether their cigarettes "ever go out between puffs" and whether they had noticed any change in the taste of their cigarettes in the past 12 months. RESULTS: NY smokers were three times more likely than smokers in other states to report that their cigarettes often went out between puffs (17.3% v 5.6%). However, NY smokers appeared no more likely to report noticing differences in cigarette taste, an intention to quit smoking, or to have made quit attempts. CONCLUSIONS: A significant minority of smokers in NY reported noticing changes in the performance of their cigarettes following the RIP law, as would be expected. However, the RIP law appears to have had no impact on the smoking habits of New Yorkers, countering arguments made by cigarette manufacturers that the law would impact consumer acceptability.

In an analysis of recent behavior with regard to quitting smoking, detailed histories were obtained on a representative sample of 5,623 Americans who had smoked in the year preceding the 1986 Adult Use of Tobacco Survey. An estimated 55.8 million Americans smoked regularly for some period during the year prior to the survey. Approximately one third (34.8%) quit for at least a day during the year prior to the survey, 28.3% quit for at least 7 days during the year prior to the survey, and 16.2% were still not smoking at the time of the survey. Of those who quit for a day, 54% had relapsed by the time of the survey. Demographic characteristics, such as age, sex, race, marital status, and education, were evaluated as predictors of making a major attempt to quit for 7 days or more. Among those who had made a major attempt, a similar analysis was done predicting success in maintaining cessation for 3 months or more. Ordinal logistic regression analyses showed that younger age and higher education predicted a major attempt to quit. There was only one group who differed markedly from all others: those who were younger and were more highly educated. Older age and being white predicted those who abstained for 3 months or longer.

BACKGROUND: The American Cancer Society, the National Cancer Institute (NCI), and the Centers for Disease Control and Prevention (CDC), including the National Center for Health Statistics (NCHS), provide the second annual report to the nation on progress in cancer prevention and control, with a special section on lung cancer and tobacco smoking. METHODS: Age-adjusted rates (using the 1970 U.S. standard population) were based on cancer incidence data from NCI and underlying cause of death data compiled by NCHS. The prevalence of tobacco use was derived from CDC surveys. Reported P values are two-sided. RESULTS: From 1990 through 1996, cancer incidence (-0.9% per year; P = .16) and cancer death (-0.6% per year; P = .001) rates for all sites combined decreased. Among the 10 leading cancer incidence sites, statistically significant decreases in incidence rates were seen in males for leukemia and cancers of the lung, colon/rectum, urinary bladder, and oral cavity and pharynx. Except for lung cancer, incidence rates for these cancers also declined in females. Among the 10 leading cancer mortality sites, statistically significant decreases in cancer death rates were seen for cancers of the male lung, female breast, the prostate, male pancreas, and male brain and, for both sexes, cancers of the colon/rectum and stomach. Age-specific analyses of lung cancer revealed that rates in males first declined at younger ages and then for each older age group successively over time; rates in females appeared to be in the early stages of following the same pattern, with rates decreasing for women aged 40-59 years. CONCLUSIONS: The declines in cancer incidence and death rates, particularly for lung cancer, are encouraging. However, unless recent upward trends in smoking among adolescents can be reversed, the lung cancer rates that are currently declining in the United States may rise again.

BACKGROUND: To improve measures of monthly tobacco cigarette smoking among non-daily smokers, predictive of future non-daily monthly and daily smoking. METHODS: Data from United States National Longitudinal Study of Adolescent to Adult Health, tracking adolescents, ages 12-21, over 14 years were analyzed. At baseline, 6501 adolescents were assessed; 5114 individuals provided data at waves 1 and 4. Baseline past 30-day non-daily smokers were classified using quantity-frequency measures: cigarettes smoked/day by number of days smoked in the past 30 days. RESULTS: Three categories of past 30-day non-daily smokers emerged using cigarettes/month (low:1-5, moderate: 6-60, high: 61+) and predicted past 30-day smoking at follow-up (low: 44.5%, moderate: 60.0%, high: 77.0%, versus 74.2% daily smokers; rτ=-0.2319, p<0.001). Two categories of non-smokers plus low, moderate and high categories of non-daily smokers made up a five-category non-daily smoking index (NDSI). High NDSI (61+ cigs/mo.) and daily smokers were equally likely to be smoking 14 years later (High NDSI OR=0.97, 95% CI=0.53-1.80 [daily as reference]). Low (1-5 cigs/mo.) and moderate (6-60 cigs/mo.) NDSI were distinctly different from high NDSI, but similar to one another (OR=0.21, 95% CI=0.15-0.29 and OR=0.22, 95% CI=0.14-0.34, respectively) when estimating future monthly smoking. Among those smoking at both waves, wave 1 non-daily smokers, overall, were less likely than wave 1 daily smokers to be smoking daily 14 years later. CONCLUSIONS: Non-daily smokers smoking over three packs/month were as likely as daily smokers to be smoking 14-years later. Lower levels of non-daily smoking (at ages 12-21) predicted lower likelihood of future monthly smoking. In terms of surveillance and cessation interventions, high NDSI smokers might be treated similar to daily smokers.

BACKGROUND: Young people are more likely to have experimented with e-cigarettes (e-cigs) compared with older adults. Few studies identify reasons for experimentation/use of e-cigs among young people; we sought to discover what drives college students to use e-cigs. METHODS: Undergraduate students (ages 18-23) at four universities in New York State were surveyed. Among e-cig ever users (n=429), reasons for use were examined. A multinomial logistic regression model analyzed the relative risk of reasons for using e-cigs among discontinued, current non-daily and current daily e-cig users. RESULTS: Using e-cigs for enjoyment was associated with current non-daily (RR=2.11, 95% CI=1.18-3.75) and current daily use (RR=19.1, 95% CI=3.71-98.54). Non-daily use was related to use because e-cigs are less toxic than cigarettes (RR=2.80, 95% CI=1.75-4.50). More daily users reported use to quit smoking compared with either non-daily or discontinued users (53.3% vs. 12.2% and 13.3%, respectively; p<0.05). Among current users, 72.3% used for enjoyment, compared with 42.9% of discontinued users (p<0.05). DISCUSSION: In contrast to adults, who often report e-cig use to quit smoking, young people are less likely to use for this reason. The exception was daily e-cig users, who often reported use for quitting/reduction of smoking. Rather, college students report usage reasons related to affect (e.g. enjoyment). Overall, enjoyment was reported more often than was use for quitting smoking; affective reasons likely play a role in the popularity of e-cigs and should be considered in future assessments of e-cig users.

BACKGROUND: Since 2007, there has been a rise in the use of electronic cigarettes (e-cigarettes). The present study uses cross-sectional data (2013) to examine prevalence, correlates and susceptibility to e-cigarettes among young adults. METHODS: Data were collected using an Internet survey from a convenience sample of 1437, 18-23 year olds attending four colleges/universities in Upstate New York. Results were summarized using descriptive statistics; logistic regression models were analyzed to identify correlates of e-cigarette use and susceptibility to using e-cigarettes. RESULTS: Nearly all respondents (95.5%) reported awareness of e-cigarettes; 29.9% were ever users and 14.9% were current users. Younger students, males, non-Hispanic Whites, respondents reporting average/below average school ability, ever smokers and experimenters of tobacco cigarettes, and those with lower perceptions of harm regarding e-cigarettes demonstrated higher odds of ever use or current use. Risky behaviors (i.e., tobacco, marijuana or alcohol use) were associated with using e-cigarettes. Among never e-cigarette users, individuals involved in risky behaviors or, with lower harm perceptions for e-cigarettes, were more susceptible to future e-cigarette use. CONCLUSIONS: More e-cigarette users report use of another nicotine product besides e-cigarettes as the first nicotine product used; this should be considered when examining whether e-cigarette use is related to cigarette susceptibility. Involvement in risky behaviors is related to e-cigarette use and susceptibility to e-cigarette use. Among college students, e-cigarette use is more likely to occur in those who have also used other tobacco products, marijuana, and/or alcohol.

We sought to describe the changing death rates from lung cancer in the US white population in sequential birth cohorts, adjusting for cohort smoking prevalence and duration. We searched the US mortality database (1960-1994) for all deaths among whites in which lung cancer was listed as the underlying cause of death. To determine the population at risk for lung cancer, we used the 1970, 1978-1980, and 1992 National Health Interview Surveys to estimate the annual number of current and recent smokers (those who had quit within 5 years) in 11 5-year birth cohorts, starting in 1901. We then determined annual lung cancer mortality rates for each birth cohort, stratified by sex and adjusting for the prevalence and duration of smoking. The population-based rates of lung cancer mortality were much higher among men than among women across all ages and birth cohorts, reflecting higher smoking rates among men. These differences decreased after we controlled for current and recent smoking within the cohorts and were slightly increased in women after we controlled for duration of smoking. Differences in lung cancer death rates across birth cohorts of US men and women primarily reflect differences in the prevalence and duration of smoking in these birth cohorts. Changes in cigarette design that have greatly reduced tar yields have a relatively small effect compared with that of people's smoking status and duration of smoking.

BACKGROUND: We sought to describe trends in the presence of lung cancer at the time of death in the United States from 1979 to 1992. METHODS: We analysed death certificate reports in the Multiple-Cause Mortality Files compiled by the National Center for Health Statistics, searching for any mention of lung cancer, lung cancer as the underlying cause of death, and comorbid conditions. RESULTS: Of the 29,042,213 decedents in the study period, 1,892,129 (6.5%) had a diagnosis of lung cancer listed on their death certificates; of these 1,892,129 decedents, 1,734,767 (91.7%) had lung cancer listed as the underlying cause of death. Decedents with lung cancer listed as being present but not the underlying cause of death were more likely to be male (relative risk [RR] 1.16, 95% confidence interval [CI]: 1.15-1.17), and older (RR 4.61, 95% CI: 4.35-4.88 for decedents older than 85 compared to those aged less than 44), but less likely to be black than white (RR 0.88, 95% CI: 0.87-0.90). The mortality rate, age-adjusted to the 1980 population, increased 23.0%, from 47.9 per 100,000 in 1979 to 58.9 per 100,000 in 1992. Over the study period, black men had the highest mortality rates (117.3-125.2 per 100,000), followed by white men (81.7-88.7 per 100,000), men of other races (37.4-46.7 per 100,000), white women (22.1-39.1 per 100,000), black women (21.4-38.2 per 100,000), and women of other races (12.6-18.1 per 100,000). Age-adjusted, state specific rates varied threefold, from 30.4 per 100,000 in Utah to 93.9 per 100,000 in Nevada. CONCLUSIONS: We conclude that the underlying cause of death data base, which captures almost 92% of decedents with lung cancer present, accurately tracks lung cancer mortality trends in the US. Mortality rates of lung cancer, which are decreasing among men, continue to increase among women.

Although the prevalence of smoking has decreased since 1980 among active duty military personnel, it remains higher than among the adult civilian population; among military veterans, the prevalence of smoking has not been well described. The objectives of this study were to describe patterns of cigarette smoking behaviors among United States veterans and nonveterans and to examine the association between military veteran status and cigarette smoking. We analyzed data from a cross-sectional survey from a national probability sample of the civilian, noninstitutionalized adult population (National Health Interview Survey supplements). We estimated the prevalence of ever, current, and former smoking, as well as crude and adjusted odds ratios (AORs) of each outcome measure among veterans and nonveterans, by gender. The prevalence of ever smoking was 74.2% (+/- 0.7%) among veterans and 48.4% (+/- 0.5%) among nonveterans; current smoking prevalence was 33.9% (+/- 1.0%) among veterans and 27.7% (+/- 0.5%) among nonveterans. Among those who had not initiated smoking before the age of 18 years, veterans were more likely than nonveterans to report ever smoking (AOR = 1.8 for men and 1.9 for women) and current smoking (AOR = 1.9 for both men and women). After statistical adjustment, no difference was seen in cessation behavior. We concluded that the prevalence of ever and current smoking was higher among U.S. military veterans. The association was the strongest among veterans who had not initiated smoking before the age of 18 years. These findings are consistent with the hypothesis that military service is a risk factor for cigarette smoking, and they support the military's current prevention and cessation efforts.

To evaluate the effects of cigarette advertising on brand switching, an accurate estimate of the extent of cigarette brand and company switching among current smokers is needed. Data from the 1986 Adult Use-of-Tobacco Survey were analyzed to estimate the percentage of adult smokers who switched cigarette brands and companies in the previous year. Approximately 9.2% of adult smokers (4.2 million) switched cigarette brands in 1986, and 6.7% (3.1 million) switched cigarette companies. The aggregate profitability of brand switching in 1986 was approximately $362 million. Based on this analysis, brand switching alone justifies only a small percentage of a cigarette company's advertising and promotion expenditures, suggesting that future research should address other potential effects of advertising, including maintenance of brand loyalty and expanding the cigarette market. Medical Subject Headings (MeSH): addictive behavior, advertising, smoking, tobacco.

AIMS: Data from the Teenage Attitudes and Practices Survey were analyzed to assess the relationship between depressive symptoms and cigarette smoking. DESIGNS, SETTING, PARTICIPANTS: Nationally representative sample of adolescents interviewed in 1989 and again in 1993. MEASUREMENTS: Prevalence rate and adjusted odds ratio for smoking at follow-up by depressive symptoms status at baseline. FINDINGS: Adolescents with depressive symptoms were more likely than other adolescents to start smoking. CONCLUSIONS: The associations between depressive symptoms and regular smoking appears to be established by adolescence.

The presence of oral smokeless tobacco lesions among adolescents may be an early indicator of increased risk for oral cancers. Data from the 1986-1987 National Survey of Oral Health in US School Children were used to examine the cross-sectional relationship between the use of tobacco and alcohol and the presence of white or whitish oral soft-tissue lesions. The sample included 17,027 schoolchildren (aged 12 to 17 years) who provided information on the use of snuff, chewing tobacco, cigarettes, and alcohol and who received oral clinical examinations. Smokeless tobacco lesions were detected in 1.5% of students (projects to about 300,000 nationally), including 2.9% of males and 0.1% of females. These lesions were more prevalent among whites (2.0%) than among African-Americans (0.2%) or Hispanics (0.8%). Modeling with multivariate logistic regression revealed that, among white males, current snuff use was the strongest correlate of lesions [odds ratio (OR) = 18.4; 95% confidence interval (CI) = 8.5-39.8], followed by current chewing tobacco use [OR = 2.5; 95% CI = 1.3-5.0]. Lesions were strongly associated with duration, monthly frequency, and daily minutes of use of snuff and chewing tobacco. These data suggest that snuff may be a stronger risk factor than chewing tobacco for smokeless tobacco lesions, but the use of either of these forms of oral tobacco exhibits a dose-response relationship with the occurrence of lesions. We found little evidence that the use of alcohol or cigarettes may increase the risk of smokeless tobacco lesions. Preventing smokeless tobacco lesions and their possible malignant transformation may be best accomplished among adolescents by preventing the use of snuff and chewing tobacco.

We used data from the 1986 Adult Use of Tobacco Survey, 10 studies of self-quitters and seven studies of treatment seekers, to illustrate how subpopulations of smokers might differ; e.g. treatment seekers vs. self-quitters and research volunteers vs. smokers in the general population. Smoking researchers may wish to use our results to determine whether their sample is similar to the population of interest.

The effect of a smokers' hotline as an adjunct to self-help manuals was examined. Subjects were 1,813 smokers recruited from a 10-county rural and small urban area. Counties were matched on demographic characteristics and assigned to a manual only or manual plus hotline condition. Subjects were followed over an 18-month period. Hotline services included taped messages and access to paraprofessional counselors. Results show a consistent, significant hotline effect across outcome measures and follow-up periods. This effect emerged either as a main effect for the hotline or as an interaction with enrollment method such that a significant hotline effect emerged for subjects who enrolled through face-to-face methods. These findings indicate the effectiveness of the hotline in enhancing self-help quit rates.

PURPOSE: To examine relationships between tobacco use and use of other substances among U.S. high school students, by gender and racial/ethnic subgroups. METHODS: Data about tobacco and other substance use were analyzed from the 1995 national Youth Risk Behavior Survey implemented by the Centers for Disease Control and Prevention. RESULTS: Compared to nonsmokers, current smokers were significantly more likely to report use of all other substances we examined, including lifetime use of cocaine, inhalants, other illegal substances, and multiple substances and current alcohol use, episodic heavy drinking, marijuana use, and cocaine use. A strong dose-dependent relationship between current cigarette smoking and other substance use was identified. Among smokeless tobacco users, a strong dose-dependent relationship was found for all examined substances with the exception of lifetime and current cocaine use. Finally, a pattern of risk emerged suggesting that the likelihood of other substance use increases as students move from no tobacco use to smokeless tobacco use only, to cigarette smoking only, and to use of both smokeless tobacco and cigarettes. CONCLUSIONS: Programs designed to prevent tobacco or other substance use should consider that such use often occurs concomitantly.

PURPOSE: To estimate the independent effect of cigarette smoking on respiratory tract symptoms and health status indicators among high school seniors. DESIGN: Consolidated data sets from one-time cross-sectional survey designs. SETTING: High schools in the United States, 1982-1989. SAMPLE: A total of 26,504 high school seniors, with an 83% response rate. MEASURES: Odds ratios for respiratory tract symptoms and health status indicators for cigarette smokers compared with nonsmokers, while controlling for sex, socioeconomic status, and use of other drugs. RESULTS: High school seniors who were regular cigarette smokers and who began smoking by grade nine were significantly more likely than never smokers to report shortness of breath when not exercising (adjusted odds ratio [OR] = 2.7), coughing spells (OR = 2.1), productive cough (OR = 2.4), and wheezing or gasping (OR = 2.6). These smokers were also more likely to have seen a doctor or other health professional for an emotional or psychologic complaint (OR = 3.0) and to rate their overall health as poorer than average (OR = 2.4). We found strong dose-response relationships for most outcome measures. CONCLUSIONS: Cigarette smoking among high school seniors is associated with respiratory tract symptoms and poorer overall physical health and may be a marker for underlying mental health problems. Smoking prevention activities directed at adolescents should include information on the early adverse health consequences of cigarette smoking.

PURPOSE: To determine the prevalence of tobacco use among Centers for Disease Control and Prevention (CDC)/Agency for Toxic Substances and Disease Registry (ATSDR) employees and the effect of the smoke-free policy on smoking behavior and air quality at work. DESIGN: A stratified telephone survey of 1181 CDC/ATSDR employees randomly selected from employee rosters. SETTING: CDC/ATSDR work sites in Atlanta, Georgia, and other major CDC locations throughout the United States and Puerto Rico. SUBJECTS: Randomly selected employees of CDC/ATSDR1, or about 22% of the total CDC/ATSDR population; 98% of eligible persons selected agreed to participate. MEASURES: Demographic and smoking history variables, attitudes toward and impact of the smoke-free policy on smoking behavior, and self-report changes in air quality were the measures used. RESULTS: Overall cigarette smoking prevalence was only 11.1%. One percent reported using chewing tobacco, 1.1% reported smoking a pipe, and 1.4% reported smoking cigars. Average self-reported, daily cigarette consumption significantly decreased after the smoking ban took effect. Overall, 90% of the employees supported the smoke-free policy, and 80% of the employees believed that smokers were complying with the smoke-free policy. Most employees believed that the air quality of work areas and nonwork areas (65% and 69%, respectively) had improved since the smoke-free policy was implemented. CONCLUSIONS: These findings are consistent with previous evaluations of smoke-free policies and suggest that most employees are generally supportive of workplace smoking restrictions. Such policies can also have a positive impact on smoking behavior and perceived air quality.
