Abstract

We tested the hypothesis that psychophysiological responses to behavioral challenges are enhanced by short-term abstinence from smoking. Blood pressure (BP), salivary cortisol levels, and withdrawal symptoms were measured after a period of smoking abstinence (18 h) or ad libitum smoking, during rest, and in response to acute behavioral challenges. Thirty habitual smokers (15 women and 15 men) participated in two laboratory sessions conducted on two separate days (after abstinence or ad libitum smoking). Cotinine concentrations in saliva and expired carbon monoxide were measured in both conditions. Abstinence produced significant withdrawal symptoms in all participants, with women reporting greater desire to smoke than men. Participants showed greater systolic BP responses to the behavioral challenges in the abstinence condition than the control condition. They also showed worse cognitive performance on the challenges in the abstinence than in the ad libitum condition. Men had greater salivary cortisol levels than women, and both men and women showed the expected decline in cortisol levels across time, but showed no difference between the abstinence and ad libitum smoking conditions in the laboratory or during ambulatory measurements. These results indicate that abstinence alters mood, performance, and BP responses to acute challenges but not adrenocortical responses. It is possible that these changes mediate stress-related vulnerability to smoking relapse.
