This study is looking at how electronic cigarettes (EC) and nicotine replacement therapy (NRT) can help people who smoke and also have obesity (BMI of 30 or higher) to quit smoking. You would be asked to switch to either EC or NRT for 8 weeks, and these products would be provided. Researchers will compare how well EC and NRT help people reduce or quit smoking, looking at things like the number of cigarettes smoked per day and carbon monoxide (CO) levels in your breath. They will also look at how these interventions affect your weight and other health factors. To join, you must be at least 21 years old, smoke at least 5 cigarettes a day, and have a high CO level in your breath. The study plans to enroll up to 60 participants.
