UW Withdraw From Tobacco Study

Summary

It is of considerable scientific and clinical importance to assess tobacco withdrawal accurately since withdrawal severity is highly determinant of smoking cessation success. In addition, smoking cessation pharmacotherapy produces its effects on smoking abstinence by suppressing such symptoms. However, in order to ensure that a measure of tobacco withdrawal is sensitive to severe withdrawal, it is essential to examine a period of unmedicated abstinence. The current study aims to validate, and possibly enhance, a revised Wisconsin Smoking Withdrawal Scale long and brief version for use in research and clinical settings.

Two hundred adults who smoke cigarettes daily and report a desire to quit smoking will be enrolled. This is a treatment-delay, one-group clinical trial that is intended to enhance the assessment of tobacco withdrawal amongst participants who try to quit smoking with delayed use of cessation medication. Participants will not receive any pharmacotherapy during the first 1 week of their quit attempt and will initiate 8 weeks of combination nicotine replacement therapy (C-NRT; nicotine patch + nicotine mini-lozenge) starting 1 week past the target quit day (TQD). Participants will receive 4 counseling sessions as well (1 pre-quit, 3 post-quit). Participants will complete 4 weeks of ecological momentary assessment (EMA) smartphone surveys including a 2-week baseline (starting TQD-14) and 2-week post-TQD (1-week un-medicated, 1-week using C-NRT).

DRUG

Combination nicotine replacement therapy (Nicotine patch + nicotine mini-lozenge)

Nicotine patch and mini-lozenge dosing will be based off the 2008 Public Health Services (PHS) Clinical Practice Guideline and package insert with adjustments to account for the delayed start 1-week post-TQD. All participants will receive 2mg mini-lozenge due to the superior palatability of the 2mg lozenges. Participants are encouraged to use at least 5 mini-lozenges per day for the full 8 weeks. Participants who report any smoking or nicotine use (e.g., even a cigarette puff, e-cigarette use) in the 3 days before C-NRT distribution will receive 4 weeks of 14mg and 4 weeks of 7mg nicotine patches. Participants who report complete abstinence from smoking and nicotine in the 3 days before C-NRT distribution will receive 8 weeks of 7mg nicotine patches.
