The behaviour of purchasing smuggled cigarettes in Taiwan

Objective: Since market liberalisation in 1987, the Taiwan Tobacco and Wine Monopoly Bureau (TTWMB) annual statistics indicate that both the demand for imported cigarettes as well as the number of seized smuggled packs have increased with an average revenue loss of NT$4942 million over the past 15 years. The NT$10 average increase in cigarette prices after Taiwan entered the World Trade Organization (WTO) and the implementation of the Tobacco and Alcohol Tax Law in 2002 are forcing policy makers to examine smuggling even more closely. This study evaluates factors that affect an individual smoker's decision to purchase smuggled cigarettes, particularly when faced with higher prices.

Design: 437 male smokers of imported cigarettes were drawn from a national interview survey on cigarette consumption, which the Division of Health Policy Research at the National Health Research Institutes conducted during the year 2000. Multiple logistic regression models were used to analyse the behaviour of purchasing smuggled cigarettes with respect to demographic factors, economic factors, smoking behaviour, and other variables.

Results: Cigarette price was the driving factor most closely linked to the purchase of smuggled cigarettes—a 1% increase in cigarette price raised the likelihood of purchasing smuggled cigarettes at least 2.60 times (95% confidence interval (CI) 1.08 to 6.26). Smokers who spent more than NT$1000/month on cigarettes were twice as likely to purchase smuggled cigarettes as those who spent less than NT$1000 (odds ratio (OR) 2.34, 95% CI 1.48 to 3.70). Betel nut chewers were more likely to purchase smuggled cigarettes (OR 1.80, 95% CI 1.09 to 2.90). Smokers who opposed cigarette taxation policy were 1.69 times more likely to buy smuggled cigarettes. Personal income was not significantly associated with smuggled cigarettes purchases.

Conclusions: This study evaluates what causes smokers to purchase smuggled cigarettes. We have determined that cigarette price is the most important factor and that betel nut vendors are the main suppliers. Our study provides policy makers with information that can help them develop effective strategies to curb cigarette smuggling after Taiwan's recent cigarette tax reform, which has increased cigarette prices.

     

Prevalence and correlates of internet cigarette purchasing among adult smokers in New Jersey

Objective: To examine the prevalence and correlates of internet cigarette purchasing among adult smokers.

Design: Analysis of internet purchasing in data from a population based telephone survey of New Jersey households. Logistic regression was used to determine factors associated with internet cigarette purchasing, adjusting for year, demographic, and smoking behaviour variables.

Participants: 3447 current cigarette smokers pooled from three cross sectional surveys conducted in 2000, 2001, and 2002.

Main outcome measures: Ever purchasing tobacco and usually buying cigarettes via the internet.

Results: Among all current cigarette smokers, ever having purchased tobacco via the internet increased from 1.1% in 2000 to 6.7% in 2002 and usually buying cigarettes via the internet increased from 0.8% in 2000 to 3.1% in 2002. Among current cigarette smokers with internet access, ever having purchased tobacco via the internet was higher among those who reported smoking 31 or more cigarettes per day (adjusted odds ratio (OR) 3.9, 95% confidence interval (CI) 1.5 to 10.2) and those without a past year quit attempt (adjusted OR 1.8, 95% CI 1.1 to 3.0). Usually purchasing cigarettes via the internet was higher among those aged 45–64 years (adjusted OR 4.4, 95% CI 1.1 to 17.1) and who reported having their first cigarette 30 minutes after waking (adjusted OR 3.3, 95% CI 1.2 to 9.2).

Conclusions: Although higher prices are known to reduce the demand for cigarettes, internet cigarette purchasing is likely to weaken this effect, particularly among heavy, more dependent smokers who are less interested in quitting.

     

An international analysis of cigarette affordability

Objective: To investigate how affordable cigarettes are in developed and developing countries, and to calculate by how much the affordability of cigarettes has changed between 1990 and 2001; and secondly, to investigate the relation between cigarette affordability and consumption.

Design: Affordability was defined as the cost of cigarettes relative to per capita income. Trends in cigarette affordability, and affordability elasticities of demand, were estimated using regression techniques.

Subjects: Seventy countries were investigated, of which 28 are categorised as high income developed countries, while 42 are categorised as developing countries. Cigarette prices were obtained for the main city/cities in the countries.

Results: Despite the fact that cigarettes are more expensive in developed countries, the high levels of income make cigarettes more affordable in these countries vis-à-vis developing countries. Of the 28 developed countries, cigarettes became more affordable in 11 and less affordable in 17 countries during the 1990s. Of the 42 developing countries, cigarettes became more affordable in 24 and less affordable in 18 countries. Based on a cross sectional analysis, a 1% increase in the relative income price (the inverse of cigarette affordability) is expected to decrease cigarette consumption by between 0.49–0.57%.

Conclusions: Cigarette affordability, more than just the price, determines cigarette consumption. While cigarettes have become more affordable in many developing countries, some developing countries (for example, South Africa, Poland, and Thailand) have implemented strong and effective tobacco control policies, and have been able to decrease cigarette consumption as a result.

     

Hand rolling cigarette papers as the reference point for regulating cigarette fire safety

Aim: To compare the burning characteristics of the tobacco and paper of manufactured and hand rolled cigarettes, and set a fire safety standard of manufacture to largely reduce the fire risk from discarded cigarettes.

Methods: (1) Cigarette extinction test of ignition strength: 40 cigarettes per brand, lit and placed on 15 layers of filter paper, in accordance with ASTM test standard E2187-02. (2) Citrate extracted by 0.1N hydrochloric acid from cigarette papers and from tobacco in manufactured cigarettes, the supernatant analysed by high performance liquid chromatography using ultraviolet visual light spectrophotometer. (3) Survey of 750 nationally representative adults age 18 years and over, by telephone, including 184 smokers.

Materials: (a) New Zealand made Holiday, and Horizon, and US made Marlboro manufactured cigarettes; (b) US manufactured Merit with banded paper; (c) Holiday, Horizon and Marlboro hand rolling tobaccos, hand rolled in Rizla cigarette papers; (d) manufactured cigarettes as in (a), reconstructed using Rizla hand rolling cigarette papers.

Results: 1. (a) For each brand of manufactured cigarettes, 40/40 burnt full length; (b) for Merit banded paper cigarettes 29/40 (73%) burnt full length; (c) for each brand of hand rolled cigarettes 0/40 burnt full length; (d) 0/40 manufactured cigarettes reconstructed with Rizla hand rolling paper burnt full length. 2. Citrate content: (a) In manufactured cigarette papers: 0.3–0.8 mg; in tobacco of manufactured cigarettes: Holiday 0, Horizon 0, Marlboro 8.8 mg; (b) Merit: in banded paper 0.418 mg; in tobacco 10.23 mg; (c) In hand rolled cigarettes: in the papers < 0.08 mg; in hand rolled tobacco 13.3–15.0 mg; (d) In hand rolling papers of reconstructed cigarettes: < 0.018 mg. 3. Requiring manufactured cigarettes to compulsorily self-extinguish when left unattended was supported by 67% of smokers, 61% of manufactured cigarette smokers, 82% of hand rolled smokers, and by 68% of non-smokers.

Conclusion: The wrapping paper is a key determinant of whether or not unpuffed cigarettes burn their full length. Using international test methods, popular brands of manufactured cigarettes all burnt full length, but none did so when re-wrapped in hand rolling cigarette paper. This provides a ready-to-hand smoker acceptable standard for reducing ignition potential from manufactured cigarettes, as a basis for regulation or litigation.

     

How do minimum cigarette price laws affect cigarette prices at the retail level?

Objectives: Half of US states have minimum cigarette price laws that were originally passed to protect small independent retailers from unfair price competition with larger retailers. These laws prohibit cigarettes from being sold below a minimum price that is set by a formula. Many of these laws allow cigarette company promotional incentives offered to retailers, such as buydowns and master-type programmes, to be calculated into the formula. Allowing this provision has the potential to lower the allowable minimum price. This study assesses whether stores in states with minimum price laws have higher cigarette prices and lower rates of retailer participation in cigarette company promotional incentive programmes.

Design: Retail cigarette prices and retailer participation in cigarette company incentive programmes in 2001 were compared in eight states with minimum price laws and seven states without them. New York State had the most stringent minimum price law at the time of the study because it excluded promotional incentive programmes in its price setting formula; cigarette prices in New York were compared to all other states included in the study.

Results: Cigarette prices were not significantly different in our sample of US states with and without cigarette minimum price laws. Cigarette prices were significantly higher in New York stores than in the 14 other states combined.

Conclusions: Most existing minimum cigarette price laws appear to have little impact on the retail price of cigarettes. This may be because they allow the use of promotional programmes, which are used by manufacturers to reduce cigarette prices. New York's strategy to disallow these types of incentive programmes may result in higher minimum cigarette prices, and should also be explored as a potential policy strategy to control cigarette company marketing practices in stores. Strict cigarette minimum price laws may have the potential to reduce cigarette consumption by decreasing demand through increased cigarette prices and reduced promotional activities at retail outlets.

     

How do smokers control their cigarette expenditures?

When faced with high cigarette prices, smokers can potentially control cigarette expenditures by limiting consumption or seeking cheaper cigarettes. The present study examined both these options and whether the use of price-minimizing strategies (the second option) could counteract a further price increase without smokers having to reduce consumption. Data for 5,109 smokers who purchased manufactured cigarettes were from the 2002 cross-sectional, population-based, random-digit-dialed California Tobacco Survey. We used logistic regression to examine which smokers used consumption-limiting or price-minimizing strategies, and multiple linear regression to determine how much price-minimizing strategies reduced the average price paid per pack. Overall, 32.3% of California smokers said they limited consumption and 74.1% used at least one of the five price-minimizing strategies identified: choosing cheaper retail outlets (61.1%), using promotional offers (35.2%), choosing cheaper brands (28.7%), purchasing by the carton (27.7%), and using low-tax or nontaxed sources (6.3%). Different groups of smokers used different strategies. Except for the use of promotional offers, all price-minimizing strategies significantly reduced the price paid per pack. Carton purchasers saved 1.01 US dollars/pack, and those buying from low-tax or nontaxed sources saved 1.23 US dollars/pack. However, pack buyers were reluctant to purchase cartons, mostly because they thought they might smoke too much, or because they considered the upfront cost unaffordable. The average California smoker could potentially save 0.33-0.66 US dollars/pack or 6.00-12.00 US dollars/month by using other price-minimizing strategies. Reducing consumption by 3 cigarettes/day could save a smoker 18.00 US dollars/month. Whereas price-minimizing strategies appeared to save money, cutting consumption could save even more. Thus further substantial tax increases would likely have the desired effect.     

Smoker and ex-smoker reactions to cigarettes claiming reduced risk

Context: The tobacco industry is introducing modified tobacco products claiming to reduce the risk of smoking (potential reduced exposure products, PREPs). If PREPs are perceived as safe, they may deter smokers from quitting and encourage re-initiation by smokers who have quit.

Objective: To assess smokers' and ex-smokers' perceptions of PREPs and the impact of PREP claims on interest in quitting (among smokers) or in resuming smoking (ex-smokers).

Design: A random-digit-dialled survey of US smokers and ex-smokers. We used Eclipse, a modified PREP cigarette, as an exemplar PREP. During the survey, the interviewer read risk reduction claims made for Eclipse by its manufacturer, assessing smokers' interest in quitting before and after the exposure.

Participants: 1000 current cigarette smokers and 499 ex-smokers (300 quit within the last two years), over 18 years old.

Main outcome measures: Perception of risk reduction from Eclipse; interest in using Eclipse; smokers' interest in quitting was assessed using a stage of change approach (pre- and post-exposure to claims).

Results: 91% of smokers thought Eclipse was safer than regular cigarettes. 24% believed Eclipse was completely safe. 57.4% of smokers were interested in using Eclipse; interest was greatest among smokers who were contemplating quitting. Exposure to Eclipse's claims was followed by reduced interest in quitting. Among all ex-smokers, interest in Eclipse was 6.2%, but interest was 15.2% among young adults (18–25 years) who had stopped smoking within two years.

Conclusions: There is substantial risk that smokers will overinterpret reduced risk claims made for modified tobacco products. PREPs appeal to smokers who are contemplating quitting and exposure to reduced risk product claims appears to reduce smokers' readiness to quit. PREPs also appealed to young adults who had recently stopped smoking. Thus, reduced risk tobacco product claims can undermine adult cessation and youth prevention, possibly resulting in increased harm even if the products are less toxic.

     

Which smokers use the smoking cessation Quitline in Hong Kong,and how effective is the Quitline?

Objective: To describe the characteristics of the Chinese subjects who utilised the first telephone smoking cessation service in Hong Kong, and to evaluate its effectiveness.

Methods: The Quitline provided Hong Kong residents with free telephone smoking cessation services which was publicised through a press conference, media reports, pamphlets, and posters at public and private hospitals and clinics. Callers who completed an initial interview from 13 December 2000 to 31 May 2002 were included. Smokers were interviewed using a structured record sheet and provided with stage matched counselling. A follow up interview was carried out after six months. Analysis was conducted by intention-to-treat.

Results: Of the 1120 callers who completed initial assessments, 1047 were current smokers and 872 consented to follow ups. Compared to the general smoking population, the Quitline attracted more of those who were female, younger, single, unemployed, higher educated, smoking more than 20 cigarettes per day, and those with quitting experience. At six months, 12% (95% confidence interval 10% to 15%) of the participants reported that they had not smoked a cigarette for the past seven days. A stepwise logistic regression model showed that the use of nicotine replacement therapy at the present attempt to quit, having made one or more serious attempts to quit in the past, perceiving less difficulties in quitting, and smoking the first cigarette at age 15 years or above were significant predictors of quitting.

Conclusion: This first Quitline in Asia appears to be acceptable to Chinese smokers, with quit rate comparable to those of better funded Quitlines in the West. A low cost Quitline is a promising model for smoking cessation services in the East.

     

Do increases in cigarette prices lead to increases in sales of cigarettes with high tar and nicotine yields?

We used scanner data on cigarette prices and sales collected from supermarkets across the United States from 1994 to 2004 to test the hypothesis that cigarette prices are positively correlated with sales of cigarettes with higher tar and nicotine content. During this period the average inflation-adjusted price for menthol cigarettes increased 55.8%. Price elasticities from multivariate regression models suggest that this price increase led to an increase of 1.73% in sales-weighted average tar yields and a 1.28% increase in sales-weighted average nicotine yields for menthol cigarettes. The 50.5% price increase of nonmenthol varieties over the same period yielded an estimated increase of 1% in tar per cigarette but no statistically significant increase in nicotine yields. An ordered probit model of the impact of cigarette prices on cigarette strength (ultra-light, light, full flavor, unfiltered) offers an explanation: As cigarette prices increase, the probability that stronger cigarette types will be sold increases. This effect is larger for menthol than for nonmenthol cigarettes. Our results are consistent with earlier population-based cross-sectional and longitudinal studies showing that higher cigarette prices and taxes are associated with increasing consumption of higher-yield cigarettes by smokers.     

Was there significant tax evasion after the 1999 50 cent per pack cigarette tax increase in California?

OBJECTIVES: Several states, including California, have implemented large cigarette excise tax increases, which may encourage smokers to purchase their cigarettes in other lower taxed states, or from other lower or non-taxed sources. Such tax evasion thwarts tobacco control objectives and may cost the state substantial tax revenues. Thus, this study investigates the extent of tax evasion in the 6-12 months after the implementation of California's 0.50 dollars/pack excise tax increase. DESIGN AND SETTING: Retrospective data analysis from the 1999 California Tobacco Surveys (CTS), a random digit dialled telephone survey of California households. MAIN OUTCOME MEASURES: Sources of cigarettes, average daily cigarette consumption, and reported price paid. RESULTS: Very few (5.1 (0.7)% (+/-95% confidence limits)) of California smokers avoided the excise tax by usually purchasing cigarettes from non- or lower taxed sources, such as out-of-state outlets, military commissaries, or the internet. The vast majority of smokers purchased their cigarettes from the most convenient and expensive sources: convenience stores/gas (petrol) stations (45.0 (1.9)%), liquor/drug stores (16.4 (1.6)%), and supermarkets (8.8 (1.2)%). CONCLUSIONS: Despite the potential savings, tax evasion by individual smokers does not appear to pose a serious threat to California's excise tax revenues or its tobacco control objectives.     

Trends and affordability of cigarette prices: ample room for tax increases and related health gains

BACKGROUND: Increasing the price of tobacco products is arguably the most effective method of curbing the prevalence and consumption of tobacco products. Price increases would reduce the global burden of disease brought about by tobacco consumption. OBJECTIVES: To compare cigarette price data from more than 80 countries using varying methods, examine trends in prices and affordability during the 1990s, and explore various policy implications pertaining to tobacco prices. DESIGN: March 2001 cigarette price data from the Economist Intelligence Unit are used to compare cigarette prices across countries. To facilitate comparison and to assess affordability, prices are presented in US dollars, purchasing power parity (PPP) units using the Big Mac index as an indicator of PPP and in terms of minutes of labour required to purchase a pack of cigarettes. Annual real percentage changes in cigarette prices between 1990 and 2000 and annual changes in the minutes of labour required to buy cigarettes between 1991 and 2000 are also calculated to examine trends. RESULTS: Cigarette prices tend to be higher in wealthier countries and in countries that have strong tobacco control programmes. On the other hand, minutes of labour required to purchase cigarettes vary vastly between countries. Trends between 1990 and 2000 in real prices and minutes of labour indicate, with some exceptions, that cigarettes have become more expensive in most developed countries but more affordable in many developing countries. However, in the UK, despite recent increases in price, cigarettes are still more affordable than they were in the 1960s. CONCLUSIONS: The results suggest that there is ample room to increase tobacco prices through taxation. In too many countries, cigarette prices have failed to keep up with increases in the general price level of goods and services, rendering them more affordable in 2000 than they were at the beginning of the decade. Opportunities to increase government revenue and improve health through reduced consumption brought about by higher prices have been overlooked in many countries.     

Smoking behaviour and toxin exposure during six weeks use of a potential reduced exposure product: Omni

Objective: To determine smoking behaviour, acceptability, and toxin exposure when smokers switch to the potential reduced exposure product—Omni cigarette.

Design: 12 week randomised, crossover study of Omni versus own cigarettes.

Participants: 19 light/ultralight and 15 regular smokers.

Outcomes: Cigarettes/day, smoking topography, craving, withdrawal symptoms, urinary cotinine plus its glucuronide (total cotinine), nicotine plus its glucuronide (total nicotine), and carcinogen metabolites (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol plus its glucuronides and 1-hydroxypyrene).

Results: When switched to Omni, smokers smoked the same number of cigarettes/day, smoked Omni cigarettes less intensely (total puff volume = –11%) and had slightly lower total cotinine (–18%) levels than their own cigarettes, but had a slightly greater carbon monoxide boost/cig (+21%). Craving and withdrawal ratings were similar with Omni and own cigarettes. Carcinogen metabolite levels were somewhat but not significantly lower with Omni. About half of smokers rated Omni as better for their health and about two thirds stated it was weaker and worse tasting than their own cigarettes.

Conclusions: Although Omni may be an adequate behavioural and pharmacological substitute for traditional cigarettes, it may not decrease carcinogen exposure and may increase carbon monoxide. Replications with larger sample sizes and longer follow up are needed. These results indicate the need for regulation of reduced exposure and reduced risk claims.

     

Impact of the graphic Canadian warning labels on adult smoking behaviour

Objective: To assess the impact of graphic Canadian cigarette warning labels on current adult smokers.

Design: A random-digit-dial telephone survey was conducted with 616 adult smokers in south western Ontario, Canada in October/November 2001, with three month follow up.

Main outcome measures: Smoking behaviour (quitting, quit attempts, and reduced smoking), intentions to quit, and salience of the warning labels.

Results: Virtually all smokers (91%) reported having read the warning labels and smokers demonstrated a thorough knowledge of their content. A strong positive relation was observed between a measure of cognitive processing—the extent to which smokers reported reading, thinking about, and discussing the new labels—and smokers' intentions to quit (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.16; p < 0.001). Most important, cognitive processing predicted cessation behaviour at follow up. Smokers who had read, thought about, and discussed the new labels at baseline were more likely to have quit, made a quit attempt, or reduced their smoking three months later, after adjusting for intentions to quit and smoking status at baseline (OR 1.07, 95% CI 1.03 to 1.12; p < 0.001).

Conclusions: Graphic cigarette warning labels serve as an effective population based smoking cessation intervention. The findings add to the growing literature on health warnings and provide strong support for the effectiveness of Canada's tobacco labelling policy.

     

Emotions for sale: cigarette advertising and women's psychosocial needs

Objective: To explore messages of psychosocial needs satisfaction in cigarette advertising targeting women and implications for tobacco control policy.

Methods: Analysis of internal tobacco industry documents and public advertising collections.

Results: Tobacco industry market research attempted to identify the psychosocial needs of different groups of women, and cigarette advertising campaigns for brands that women smoke explicitly aimed to position cigarettes as capable of satisfying these needs. Such positioning can be accomplished with advertising that downplays or excludes smoking imagery. As women's needs change with age and over time, advertisements were developed to reflect the needs encountered at different stages in women's lives. Cigarette brands for younger women stressed female camaraderie, self confidence, freedom, and independence; cigarette brands for older women addressed needs for pleasure, relaxation, social acceptability, and escape from daily stresses.

Conclusions: Psychosocial needs satisfaction can be communicated without reference to cigarettes or smoking. This may explain why partial advertising bans are ineffective and comprehensive bans on all forms of tobacco marketing are effective. Counter-advertising should attempt to expose and undermine the needs satisfaction messages of cigarette advertising campaigns directed at women.

     

Point of purchase cigarette promotions before and after the Master Settlement Agreement: exploring retail scanner data

Background

Evidence indicates that point of purchase (POP) advertising and promotions for cigarettes have increased since the Master Settlement Agreement (MSA). Retail promotions have the potential to offset the effects of cigarette tax and price increases and tobacco control programmes.

Objective

To describe the trend in the proportion of cigarette sales that occur as part of a POP promotion before and after the MSA.

Design

Scanner data were analysed on cigarette sales from a national sample of grocery stores, reported quarterly from 1994 through 2003. The proportion of total cigarette sales that occurred under any of three different types of POP promotions is presented.

Results

The proportion of cigarettes sold under a POP promotion increased notably over the sample period. Large increases in promoted sales are observed following implementation of the MSA and during periods of sustained cigarette excise tax increases.

Conclusions

The observed pattern of promoted cigarette sales is suggestive of a positive relationship between retail cigarette promotions, the MSA, and state cigarette tax increases. More research is needed to describe fully the relationship between cigarette promotions and tobacco control policy.     

Investigating cigarette affordability in 60 cities using the cigarette price-daily income ratio

Objective

To investigate cigarette affordability in 60 cities.

Methods

Affordability of cigarettes is defined as the ratio of the price of one pack of cigarettes to daily income (cigarette price‐daily income ratio: CPDIR). Daily income data were calculated using the mean of the seven occupations with the lowest daily wage, as listed in the 2006 Union Bank of Switzerland survey; cigarette prices in 2006 were sourced from the Economist Intelligence Unit.

Results

Cigarette affordability in most of the surveyed cities remains high. There is a tendency for cities with high income economies to have a high level of cigarette affordability. Most of the cities in Western Europe and South and North America have high cigarette affordability, whereas 66.7% of their counterparts in Eastern Europe have medium cigarette affordability. In Asia, all cities with high cigarette affordability belong to the group of upper middle to high income economies, except for the Philippines. In Africa, Johannesburg and Nairobi have high and medium levels of cigarette affordability, respectively.

Conclusion

Cigarette affordability for most of the sampled cities, especially those in high income economies, is high. There is room for increasing cigarette prices via tax increases. There is a risk that the increase in cigarette prices in newly emerging economies lags behind the high speed of economic growth being experiencing. Tax increases should be given high priority.     

Higher nicotine and carbon monoxide levels in menthol cigarette smokers with and without schizophrenia.

This study examined whether smoking menthol cigarettes was associated with increased biochemical measures of smoke intake. Expired carbon monoxide (CO) and serum nicotine and cotinine were measured in 89 smokers with schizophrenia and 53 control smokers immediately after smoking an afternoon cigarette. Serum nicotine levels (27 vs. 22 ng/ml, p = .010), serum cotinine levels (294 vs. 240 ng/ml, p = .041), and expired CO (25 vs. 21 ppm, p = .029) were higher in smokers of menthol compared with nonmenthol cigarettes, with no differences in 3-hydroxycotinine/cotinine ratios between groups when controlling for race. Backward stepwise linear regression models showed that, in addition to having a diagnosis of schizophrenia, smoking menthol cigarettes was a significant predictor of nicotine and cotinine levels. Individuals with schizophrenia or schizoaffective disorder smoked more generic or discount value brands (Basic, Doral, Monarch, USA, Wave, others) compared with control smokers (28% vs. 6%, p = .002) but did not smoke more brands with high nicotine delivery as estimated by the U.S. Federal Trade Commission method. Although rates of mentholated cigarette smoking were not higher in smokers with schizophrenia overall, they were significantly higher in non-Hispanic White people with schizophrenia compared with controls of the same ethnic/racial subgroup (51% vs. 28%, p<.0001). The higher exhaled CO in menthol smokers suggests that the higher nicotine levels are at least partly related to increased intake of smoke from menthol cigarettes, although menthol-mediated inhibition of nicotine metabolism also may be a factor. Menthol is an important cigarette additive that may help explain why some groups have lower quit rates and more smoking-caused disease.     

Delayed compensatory cigarette consumption after a workplace smoking ban

OBJECTIVES: To evaluate the impact of workplace smoking bans on cigarette consumption among continuing smokers over a two-year period. DESIGN: Two cross-sectional surveys and a longitudinal sample of smokers questioned about their smoking behaviour six months and two years after implementation of a workplace smoking ban. SUBJECTS: Workers in 46 government offices in Australia. The cross-sectional survey six months after the ban included 3388 workers, whereas the survey two years after the ban included 3982 workers. The longitudinal cohort study included 107 workers who were identified as current smokers in both surveys. MAIN OUTCOME MEASURES: Smokers were asked to report usual daily cigarette consumption on both workdays and leisure days one month before implementation of the ban, and six months, and two years afterwards. RESULTS: From six months to two years after the ban, the cross-sectional data showed an increase in cigarette consumption of 1.3 cigarettes per day. The longitudinal sample of smokers reported an increase in workday cigarette consumption of 1.7 cigarettes per day. A previous study of workers in the same worksites found a reduction in consumption of 5.2 cigarettes per day from before the ban to six months after. Over a two-year period we estimate that the net effect of the workplace smoking ban was to reduce cigarette consumption by about 3.5 cigarettes per day. CONCLUSIONS: Reductions in cigarette consumption among smokers frequently seen after implementation of a worksite smoking ban may diminish over time. This effect is more likely to occur when the initial response to a smoking ban is a large reduction in cigarette consumption.


     

Demand analysis of tobacco consumption in Malaysia.

We estimated the price and income elasticity of cigarette demand and the impact of cigarette taxes on cigarette demand and cigarette tax revenue in Malaysia. The data on cigarette consumption, cigarette prices, and public policies between 1990 and 2004 were subjected to a time-series regression analysis applying the error-correction model. The preferred cigarette demand model specification resulted in long-run and short-run price elasticities estimates of -0.57 and -0.08, respectively. Income was positively related to cigarette consumption: A 1% increase in real income increased cigarette consumption by 1.46%. The model predicted that an increase in cigarette excise tax from Malaysian ringgit (RM) 1.60 to RM2.00 per pack would reduce cigarette consumption in Malaysia by 3.37%, or by 806,468,873 cigarettes. This reduction would translate to almost 165 fewer tobacco-related lung cancer deaths per year and a 20.8% increase in the government excise tax revenue. We conclude that taxation is an effective method of reducing cigarette consumption and tobacco-related deaths while increasing revenue for the government of Malaysia.     

An extremely compensatible cigarette by design: documentary evidence on industry awareness and reactions to the Barclay filter design cheating the tar testing system

Background: The Barclay cigarette (Brown & Williamson) was introduced in 1980 in the USA in the most expensive launch in history. In the USA and around the world, Barclay was later determined to have a grooved filter design that was compromised by human smokers in the normal act of smoking, but that was measured as ultra-low tar using the standard tar testing protocol.

Objectives: To evaluate whether Brown & Williamson knew of the compensatability of Barclay during the design process and before it was released; to evaluate initial responses of competing tobacco companies to Barclay, before complaints were made to the Federal Trade Commission in 1981.

Methods: Internet databases of industry documents (Tobacco Documents Online, Legacy Tobacco Documents Library, Brown & Williamson Litigation discovery website, Guildford and major company websites) were searched using key words, key dates, and targeted searches. Documents related specifically to the development, evaluation and release of the Barclay cigarette and related to the responses by competing tobacco companies were examined.

Results: Documents indicate the manufacturer was aware of Barclay design problems and was planning, before release, to respond to criticism. Competing companies quickly detected the filter groove stratagem and considered developing their own similar filter, but eventually backed off.

Conclusion: The design problems with Barclay were readily understood by cigarette manufacturers, including the maker of Barclay, before official governmental evaluations occurred. Testing involving measured exposures to human smokers may in the end be crucial to identifying problems with novel cigarette designs.
