Title: Randomized Controlled Trial of Mailed Nicotine Replacement Therapy to Canadian Smokers
Brief Summary: This study will examine the efficacy of mailed distribution of free Nicotine Replacement Therapy to smokers. Telephone numbers will be randomly selected from across Canada in order to recruit adult smokers interested in completing a smoking survey and willing to be interviewed again in 8 weeks and 6 months time. Study participants will be asked about their smoking history and a hypothetical question: would they be interested in receiving the nicotine patch if this were to be provided to them free of charge? Participants expressing interest will be randomly assigned to one of two groups. One group will be offered the opportunity to actually receive a program of 5 weeks of the nicotine patch for free right away and the other group will not be offered the free nicotine patches. The proportions of smokers in the two groups who quit smoking by the 6-month interview will be compared.
