Worksite smoking control, discouragement, and cessation

Smoking control, discouragement, and cessation were investigated at three comparable chemical plants. One plant was randomly assigned to smoking cessation only while the other two plants were assigned to a comprehensive program of smoking control, discouragement, and cessation. Three weeks later, smoking cessation was provided at all three sites. Results are consistent with a previous investigation of the comprehensive program carried out at two oil refineries. Not only was there a greater rate of participation in the smoking cessation program with the comprehensive program, 4 months after completion of smoking cessation treatment revealed significant changes on all outcome variables in the expected direction and suggest the superiority of a comprehensive program of smoking control, discouragement, and cessation over cessation alone.
