A smoke-mixing device for measuring nicotine preference

A smoke-mixing device is described that allows individuals to select their preferred nicotine deliveries from cigarette smoke on a puff-by-puff basis. This methodology offers advantages over previous strategies to investigate the role of nicotine as a reinforcing constituent of tobacco.     

Situational Determinants of Coping in Smoking Relapse Crises1

Interviews with 264 callers to a relapse prevention hotline were used to explore situational determinants of coping among exsmokers facing temptations to smoke. As hypothesized, subjects were more likely to perform cognitive and behavioral coping early in abstinence. Coping was also more likely in situations where subjects had habitually smoked. Discriminant function analyses were used to predict the performance of coping from situational variables. Cognitive coping could not be predicted. Performance of behavioral coping was predictable from six situational variables which accounted for 28% of the variance in coping performance. These situational variables also accounted for the decay of behavioral coping over time. The findings imply that individual differences play a limited role in coping performance and have implications for clinical efforts to enhance smoking cessation through coping interventions.
