[Tobacco withdrawal. Comparison of the efficacy of various methods. Intermediate results of a comparative study].

A comparative study aimed at evaluating the effectiveness of different methods of detoxication for dependent smokers is currently in progress. In this study, the percentage of subjects who gave up smoking after 1 month and changes in this percentage over a 12-month period are determined in 3 groups of subjects: one group treated with acupuncture, one group treated with a chewing-gum containing nicotine, and a control group. The intermediate analysis results include 45% of the total number of subjects required. They show no statistically significant difference between the control group and the two treated groups. Volunteers are still being recruited.
