Abstract
The present study of the everyday behavior of nicotine misusers, belongs to a series of studies using a special technique for conveniently reaching the subjects at any time, anywhere and to sample their everyday behavior. One purpose of the study was to help a group of habitual smokers to quit smoking. Another purpose was to study how nicotine misusers differ from matched non-smoking people, and to obtain a psychological profile of them before and during their attempts to quit. The belief was that an experimental design with a moral contract and electronic surveillance would facilitate the smokers' attempts to quit. The results in terms of terminated and reduced smoking were very satisfactory and the method of random action sampling made detailed descriptive and explorative analyses possible.
