Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine whether smokers who initially respond (within 2 weeks) to nicotine products (including nicotine replacement therapy, e-cigarettes, nicotine pouches) by reducing their smoking by ≥50% can be successfully maintained on use of these noncombustible nicotine alternatives to cigarettes for 6 months, and whether this results in sustained smoking reduction/abstinence.
