Randomized Controlled Trial
Comparison of the Pharmacokinetics of Nicotine Following Single and Ad Libitum Use of a Tobacco Heating System or Combustible Cigarettes.
We aimed to compare the pharmacokinetics of nicotine between the heat-not-burn Tobacco Heating System 2.1 (THS 2.1) and combustible cigarettes (CCs). We also examined whether the subjective urge to smoke was associated with the pharmacokinetics of nicotine. ⋯ Reducing exposure to toxicants and safer delivery of nicotine are among the strategies that may reduce the harm of smoking-related diseases. In the present study, we investigated the pharmacokinetics of nicotine and their effects on the urge to smoke using the THS 2.1. It was developed to replicate the ritual of smoking as closely as possible by providing nicotine in a way that mimics CC smoking, but limits pyrolysis and combustion by heating tobacco at a much lower temperature than CCs (heat-not-burn).

Electronic cigarettes (ECIGs) aerosolize a liquid that usually contains propylene glycol and/or vegetable glycerin, flavorants, and the dependence-producing drug nicotine in various concentrations. This study examined the extent to which ECIG liquid nicotine concentration is related to user plasma nicotine concentration in ECIG-naïve tobacco cigarette smokers. ⋯ Liquid nicotine concentration can influence plasma nicotine concentration in ECIG-naïve cigarette smokers, and, at some concentrations, the nicotine delivery profile of a 3.3V ECIG with a dual coil, 1.5-Ohm cartomizer approaches that of a combustible tobacco cigarette in this population. Finding a product that delivers nicotine as effectively as a tobacco cigarette, as we report here, may be essential for smokers who want to replace completely their combustible tobacco cigarettes with ECIGs.

Lung cancer screening represents an opportunity to deliver smoking cessation advice and assistance to current smokers. However, the current tobacco treatment practices of lung cancer screening sites are unknown. The purpose of this study was to describe organizational priority, current practice patterns, and barriers for delivery of evidence-based tobacco use treatment across lung cancer screening sites within the United States. ⋯ This study is the first to describe practice patterns, organizational priority, and barriers for delivery of smoking cessation treatment in a national sample of lung cancer screening sites.

Televised direct-to-consumer advertising (DTCA) for prescription drugs is controversial, especially for tobacco cessation products such as varenicline, given safety concerns that arose only after its market approval. We aim to quantify the extent to which DTCA influenced varenicline use. ⋯ We examined the fluctuations in varenicline use in association with DTCA for varenicline and other tobacco cessation aids. To our knowledge this is the first study to quantify the effects of televised DTCA for varenicline and other tobacco cessation aids on varenicline prescription dispensing. We believe that understanding these relationships is critical for formulating effective public health policy and interventions.

Previous studies have demonstrated the influence of parental (both mother and father) cigarette smoking on adolescents' cigarette smoking. Little is known, however, about how parental tobacco use is related to waterpipe and dual waterpipe/cigarette use, which is increasing dramatically in the Arab countries. ⋯ (1) Influence of parents' cigarette smoking on adolescents' smoking has been demonstrated in earlier studies, however, little is known about how tobacco use behaviors of mother and father influences an adolescent's cigarette, waterpipe and dual cigarette/waterpipe use. (2) Associations of parental (both mother and father) tobacco use with adolescents' tobacco use differed significantly if the adolescent is a waterpipe smoker or dual user compared to an adolescent cigarette smoker. (3) Adolescents' exposed to their mothers' WPS or dual use were more likely to be a waterpipe smoker or dual user. High likelihood of adolescents' cigarette, waterpipe and dual use is found in homes where parental tobacco use is rampant with both parents smoking either cigarette, waterpipe or both.
