Brief Summary

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.

Secondary Outcomes (4)

  • Smoking abstinence - Self report of no smoking

    Week 12 and Week 24

  • Reduction in Expired Air CO

    Week 12 and Week 24

  • Usage of Nicotine Products

    Week 1 through Week 24, Week 36

  • Saliva Cotinine Concentrations

    Week 12, Week 24, Week 36
