CAN-DOSE Study: Cessation With Augmented Nicotine for Dual Use Of Smoking and E-cigarettes

Overview

Many people smoke cigarettes and use e-cigarettes, and have a hard time stopping. Nicotine replacement therapy medications, such as nicotine patches and lozenges, have been shown to help people quit e-cigarette use. The purpose of the present study is to see how well nicotine patches and lozenges help people quit both smoking and vaping, and to determine if higher doses of the medication work best.

Tobacco use is a leading cause of cancer death and disability in the US, thus tobacco control remains an important public health priority. Alternative tobacco products have grown popular in the past decade, including electronic cigarettes (e-cigarettes; vaping). E-cigarettes were initially marketed as an alternative to or means for smoking cessation and became popular amongst those currently smoking. Recent estimates suggest that 54% of those who vape are currently smoking (i.e., dual use). Despite this, there is a lack of empirically tested interventions for dual use cessation among the general adult population. In a prior pilot study, investigators found preliminary evidence that a standard dose of nicotine replacement therapy (NRT; 21mg patch+4mg lozenge) was sufficient at helping exclusive e-cigarette users quit vaping. However, dual users (individuals who smoke cigarettes and use e-cigarettes) did not respond similarly. The proposed project aims to compare three doses of NRT (21mg patch+4mg lozenge; 21+14mg patch + 4mg lozenges; 21+21mg patch + 4mg lozenges) with a sample of dual users who wish to quit smoking and vaping use in order to understand more about how NRT can help dual users quit tobacco.
