Adaptive Use of Nicotine Substitution to Maintain Smoking Reduction/Abstinence in Nicotine Responders
Completed · Phase 3
Conditions studied: Smoking Cessation, Harm Reduction
In brief
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.
