This study examined perceived risk of harm from smoking or ST use in a U. S. nationally representative sample of high school seniors and examined its association with current smoking status. Data were derived from the Monitoring the Future project for 1999 through 2003 (n = 11,093). ⋯ Adjusting for sex and race, high school seniors who perceived that smoking conveyed a greater risk for harm than did using smokeless tobacco were significantly more likely to be smokers than were those who perceived equal risk from the products (odds ratio [OR] = 1.43; 95% confidence interval [CI] 1.29-1.60). Those who perceived that using smokeless tobacco was riskier than smoking were even more likely to be current smokers (OR = 2.43; 95% CI 1.96-3.01). Effective methods for communicating accurate health risks to young people are needed.

This paper assesses rates of the 5A's (ask, advise, assess, assist, and arrange) of brief provider counseling received by Medicaid-enrolled smokers and recent quitters and the differences in receipt of counseling as a function of age, gender, race, ethnicity, and health status. A random sample telephone survey was conducted among Medicaid-enrolled smokers and recent quitters in four geographic areas in the United States. Multivariate logistic regression models estimated the relationships between demographic characteristics and delivery of the 5A's. ⋯ However, they were much less likely to provide comprehensive counseling, with fewer than 25% of patients reporting receiving any assistance with quitting (i.e., a prescription for pharmacotherapy or referral to counseling) or arrangement of a follow-up visit or phone call. Receipt of the 5A's varied as a function of health status, race, and ethnicity. Medicaid needs to (a) increase provider delivery of the full spectrum of counseling interventions recommended for smoking cessation and (b) extend provider outreach to the demographic groups that receive the lowest rates of counseling.

Randomized Controlled Trial Controlled Clinical Trial
Treating smokers before the quit date: can nicotine patches and denicotinized cigarettes reduce cravings?
The present study investigated whether treatment with the combination of denicotinized cigarettes and 21-mg nicotine patch for 2 weeks before a designated quit date could lessen cravings for smoking, thereby helping smokers abstain from smoking. The study was a randomized controlled clinical trial conducted at Roswell Park Cancer Institute, Buffalo, New York, in 2004 and 2005. Patients included 98 adult heavy smokers (using 20 or more cigarettes/day). ⋯ Self-reported withdrawal symptoms and quit rates did not differ significantly between the groups. The use of a denicotinized cigarette combined with the nicotine patch appears to lessen cravings to smoke in the immediate postcessation period. A larger, better-powered study is needed to test if this treatment combination has merit for increasing quit rates.

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. ⋯ 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.

Potential reduced exposure products (PREPs) purport to lower toxicant emissions, but without clinical and long-term health outcome data, claims for reduced harm status of PREPs depend heavily on standard machine yield smoke constituent data. Two prototypes of the new carbon-filtered PREP Marlboro UltraSmooth (MUS) were investigated using both standard (FTC/ISO) and intensive (Health Canada) machine methods to measure gas/vapor- and particulate-phase smoke constituents. Basic physical design characteristics that may influence smoke constituent yields, such as ventilation, pressure drop (resistance to draw), quantity of tobacco, and quantity and type of carbon, were measured. ⋯ Particulate-phase constituents were not reduced by the carbon filter under either machine-smoking regimen. The data suggest that MUS has been designed to reduce toxic yields while preserving consumer appeal. However, MUS is less effective in reducing toxic smoke constituents when smoked under intensive conditions.
