NCT06260683

Brief Summary

This clinical trial compares the use of tobacco flavored electronic cigarettes (ECs) vs. non-tobacco flavored ECs vs. nicotine replacement therapy (patches and lozenges) on smoking behavior in current cigarette smokers. ECs may reduce cigarette craving and withdrawal symptoms, increase motivation and confidence to stop cigarette smoking, and decrease cigarette smoking and dependence. By comparing participants' preferred flavor ECs (PEC) to tobacco flavor ECs (TEC) to NRT, researchers hope to determine the effect of EC flavors on appeal and use and learn how ECs affect smoking behaviors and health.

Outcome Measures

Primary Outcomes (3)

  • 7-day point prevalence complete switching rate

    Self-reported 7-day point prevalence abstinence (no cigarettes, not even a puff, in the previous 7 days), any reported use of ECs or NRT over the past 7 days, and an exhaled CO reading of ≤6ppm.

    At week 14

  • Biochemically verified 7-day point prevalence abstinence from cigarettes

    Biochemical verification of abstinence from cigarettes (exhaled CO reading of ≤6ppm) combined with self-reported 7-day point prevalence abstinence (no cigarettes, not even a puff, in the previous 7 days).

    At week 14

  • Cigarettes smoked per day

    Cigarettes smoked per day as evaluated with the timeline follow-back questionnaire.

    At week 14

Secondary Outcomes (7)

  • Change in cigarettes smoked per day

    From baseline to 26 weeks

  • Change in nicotine dependence

    From baseline to 14 weeks

  • Changes in cigarette craving and nicotine withdrawal

    At baseline, 2, 6, 14, and 26 weeks

  • Number of days used in past week

    At 2, 6, and 14 weeks

  • Number of days used in past month

    At 6 and 14 weeks

  • +2 more secondary outcomes
