Brief Summary

The main goal of the present study is to determine if a smoking cessation program designed for people living with certain chronic conditions and delivered via videoconferencing groups works better than a control condition--a program that is not designed to help with smoking but that does have the same number of group contact hours as the other program (this program is called the Attention Matched Control condition; AMC) for helping people with certain health conditions stop smoking. People in both groups will receive brief advice to quit and an offer of nicotine replacement therapy patches (NRT), as well as 12 videoconferencing group sessions. The team will measure smoking behavior over a one-year period and compare smoking rates for the treatment condition against AMC to see if the treatment condition is better at getting people living with certain health conditions to quit smoking.
