Anxiolytic effects of smoking associated with four stressors.

There is a widespread belief that cigarette smoking alleviates stress. The literature reveals conflicting results on the anxiolytic effects of smoking. This study was designed to replicate a report that smoking (a) reduced subjective anxiety induced by stressful anagrams and (b) increased pain threshold for a cold pain task. This study (N = 15) included two other stressors: white noise and an auditory vigilance task. A significant Time x Condition (smoking vs. deprived) interaction was found for Spielberger State Anxiety Inventory scores in the anagram task. A borderline significant interaction effect was found for the cold pain task. No significant effects were found with the two other tasks. These results provide partial support for the popular notion that smoking mitigates stress-induced anxiety. No difference was found between the smoking and deprived conditions for either pain threshold or pain endurance.
