A Comprehensive Evaluation of Tobacco-Flavored vs. Non-Tobacco Flavored E-cigarettes on Smoking Behavior

Description

PRIMARY OBJECTIVES:

I. Determine PEC versus vs. TEC vs. nicotine replacement therapy (NRT) on tobacco use patterns including product switching, abstinence from cigarettes, and number of cigarettes smoked.

II. Examine PEC vs. TEC vs. NRT on cigarette craving, withdrawal symptoms, and perceived nicotine dependence.

III. Examine PEC vs. TEC on product appeal and uptake, including initial trial, days used during period of product provision, and purchase and continued use after 12 weeks.

OUTLINE: Participants are randomized to 1 of 3 arms.

ARM I: Participants receive PEC for 14 weeks, including a 2-week pre-switch period to become familiar with usage.

ARM II: Participants receive TEC for 14 weeks, including a 2-week pre-switch period to become familiar with usage.

ARM III: Participants receive NRT (nicotine patches and lozenges) for 14 weeks, including a 2-week pre-switch period to become familiar with usage.

Participants in all arms participate in discussions throughout the trial.

SURVEILLANCE PHASE: Participants in all arms are followed for 12-weeks after completion of study procedures.
