Official title

E-cigarettes as Harm Reduction Tools in Smokers Who Fail to Quit With Traditional Methods

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The majority of smokers try to quit each year, and the majority of quit attempts fail, even when the most effective FDA-approved pharmacotherapies are used. Non-combustible tobacco products emit fewer harmful chemicals than cigarettes, and thus for smokers who cannot quit smoking, switching completely to a less harmful product is likely to improve their risk of cancer and other deleterious health outcomes. E-cigarettes, the most commonly used non-cigarette tobacco product, have been shown to deliver sufficient nicotine, be appealing to smokers, and reduce cigarette smoking when provided to smokers to use ad libitum. For smokers who have failed to quit with traditional methods, trying to switch to a less harmful product may be more likely to help them stop smoking than trying to quit using tobacco altogether repeatedly with pharmacotherapy. The proposed trial evaluates the potential of e-cigarettes to serve as harm reduction tools for current smokers who have already tried, and failed, to quit with traditional methods. Current smokers who failed to quit with FDA-approved pharmacotherapy within the past year (N=30) will be randomly assigned to either 1) switch completely to e-cigarettes (Switch Group, n=20), or 2) try to quit again using pharmacotherapy (Meds Group, n=10). Thus, our design is strengthened by a strong active control group. Participants will select a Target Switch / Quit Date on which they will stop smoking. Participants in the Switch group will receive a 5-week supply of JUUL e-cigarettes, the most popular e-cigarette currently available. Participants in the Meds Group will receive a 5-week supply of combination nicotine replacement therapy (transdermal nicotine patch and short-acting nicotine lozenge). Participants will use 1-week of their tobacco product or medication ad libitum while continuing to smoke in advance of their Target Switch / Quit Date, and 4-weeks as instructed following a Target Switch or Quit Date. Behavioral outcomes of interest include smoking reduction \> 50% and biochemically-confirmed abstinence from cigarette smoking at 4-weeks. The proposed trial addresses a highly significant research question using a rigorous design and is supported by a strong investigative team.
