Comparative Study
Waterpipe tobacco smoking and cigarette smoking: a direct comparison of toxicant exposure and subjective effects.
Waterpipe tobacco smoking is increasing worldwide and is believed by many users to be less harmful and addictive than cigarette smoking. In fact, waterpipe tobacco and cigarette smoke contain many of the same chemicals, and users are exposed to the dependence-producing drug nicotine as well as other smoke toxicants. The subjective effect profile of these 2 tobacco use methods has not been compared directly, though this information is relevant to understanding the risk of dependence development. ⋯ Relative to a cigarette, waterpipe tobacco smoking was associated with similar peak nicotine exposure, 3.75-fold greater COHb, and 56-fold greater inhaled smoke volume. Waterpipe and cigarette influenced many of the same subjective effect measures. These findings are consistent with the conclusion that waterpipe tobacco smoking presents substantial risk of dependence, disease, and death, and they can be incorporated into prevention interventions that might help deter more adolescents and young adults from experimenting with an almost certainly lethal method of tobacco use.

To examine the time patterns and predictors of initiating a quit attempt and subsequent sustained abstinence among youth smokers after receiving a telephone smoking cessation intervention. ⋯ Our findings support the "catastrophic" pathway of youth smokers initiating a quit attempt. Counselors should capture the quitting momentum and motivate youth smokers to quit immediately. Interventions should include a health assessment and discussion of smokers' physical fitness. During the first week of abstinence, intensive monitoring of withdrawal symptoms, together with booster counseling, is helpful in preventing smoking relapse and could remotivate those who fail to sustain their quit attempt.

Sensory perception is a key determinant of smoking behavior and, therefore, reinforcement and addiction. The tobacco industry has conducted extensive research on the chemosensory and physiological effects of menthol in tobacco smoke and has actively promoted menthol's sensory characteristics. ⋯ The industry considers menthol to be an important tool for modulating the sensory effects of nicotine in different product variations, particularly those designed to be acceptable to "starters" or people interested in quitting. Regulatory efforts should consider that menthol enables the tobacco industry to customize a highly addictive product in a manner that contributes to initiation and deters cessation due to its chemosensory effects.

Comparative Study
Behavioral effects of nicotine withdrawal differ by genetic strain in male and female adolescent rats.
Gender and ethnicity are powerful predictors of initiation and maintenance of cigarette smoking in adults but less is known about their role in smoking in adolescents. Consistent with human studies, rat models also reveal sex and strain differences in response to nicotine administration. ⋯ Results indicate that nicotine withdrawal in adolescent rats depends on sex and strain.

Comparative Study
Substance abuse treatment counselors and tobacco use: a comparison of comprehensive and indoor-only workplace smoking bans.
While indoor smoking bans reduce employee tobacco use, less is known about whether comprehensive bans, which prohibit smoking in both indoor and outdoor areas, are associated with lower rates of tobacco use than indoor-only bans. ⋯ Although relatively few substance abuse counselors worked in treatment organizations with comprehensive bans, such bans may represent a promising direction for tobacco control. Given recent research documenting how tobacco use is negatively associated with the delivery of smoking cessation services by health care workers, additional research on the impact of comprehensive environmental tobacco policies is needed.
