Nicotine preference increases after cigarette deprivation.

In order to test the theory that nicotine is a reinforcing constituent in tobacco, smokers' nicotine preference was assessed after two hours' cigarette deprivation and immediately after smoking two cigarettes. Preference was measured by allowing subjects to freely adjust the nicotine concentration of each puff using a smoke mixing device. Nicotine preference was significantly higher after deprivation, showing that nicotine in cigarette smoke is positively reinforcing and smokers' attempts to obtain nicotine vary with prior cigarette consumption.

Cigarette smoking during anxiety-provoking and monotonous tasks.

Cigarette smokers were exposed to three conditions within a single session: stagefright anxiety, monotonous concentration, and a relaxation control. One cigarette was lit during the second 10-minute half of each condition, and smoking topography (number of puffs and cumulative volume smoked) was continuously recorded. Subjects smoked significantly more in the two task conditions than during relaxation, supporting the hypothesis that anxiety-provoking and attention-demanding situations elicit smoking. Younger subjects increased their smoking more than older subjects during stagefright , and females responded more than males to the concentration task.
