Initial exposure to nicotine in college-age women smokers and never-smokers: a replication and extension.

Recent research suggests that people who become smokers may be more sensitive to the positive effects of nicotine upon initial exposure than those who do not take up smoking. The present study was designed to extend these findings to a sample of college-age women never-smokers and light smokers. Subjects were asked to rate pleasurable and displeasurable sensations upon first smoking and to indicate the presence or absence of pleasurable rush or buzz, relaxation, dizziness, nausea, and cough. Pleasurable sensations were marginally greater in smokers; pleasurable rush or buzz and dizziness were significantly more likely to be reported by smokers. Relaxation, displeasurable sensations, nausea, and cough did not differ significantly between groups. Fagerstrom Test for Nicotine Dependence scores significantly predicted pleasurable but not displeasurable sensations; Center for Epidemiological Studies-Depression scores predicted neither. These findings lend further support to the following conclusions: (1) people who become cigarette smokers experience more pleasurable sensations upon initial exposure to tobacco than their never-smoking counterparts; and (2) unpleasant reactions to the first cigarette do not protect against subsequent smoking.
