Summary

This study tests whether nicotine pouches or mini lozenges can help people replace cigarettes. 300 adult smokers who aren't ready to quit will use one of these products or no product for a week, then try to stop smoking for 3 weeks. Researchers will track how many cigarettes they smoke and how strong their cravings are.
