Many people smoke cigarettes and use e-cigarettes, and have a hard time stopping. Nicotine replacement therapy medications, such as nicotine patches and lozenges, have been shown to help people quit e-cigarette use. The purpose of the present study is to see how well nicotine patches and lozenges help people quit both smoking and vaping, and to determine if higher doses of the medication work best.

This study aims to learn more about the experiences of people with cancer who smoke who are ages 18 or older. We want to learn more about what has helped or made it difficult to quit smoking, and what patients think about using videos to help quit smoking. Interviews and surveys will be used to help us learn more about the unique needs of cancer patients who smoke, and will guide the development of interventions to help with smoking cessation.

Smoking is one of the main public health problems. Smoking cessation is difficult because of nicotine dependence. Repetitive transcranial magnetic stimulation (rTMS) over the frontal head has shown to be effective in the reduction of cigarette consumption and craving. In this study, we will evaluate the efficiency of a new form of rTMS called intermittent theta-burst stimulation (iTBS) for smoking cessation.
