Support Person Intervention to Promote a Smoking Helpline

This study is designed to examine if a telephone-based intervention delivered to a support person (i.e., friend, spouse of a smoker) increases the smoker's use of the Minnesota helpline. In addition, the study will examine if the rate of smoker calls to the helpline is greater if the support person receives 3 intervention calls, 1 intervention call, or no calls (written materials only, control condition).
