A Randomized Controlled Trial of Smoking Cessation Treatment for Young Adult Dual Users of Combustible and Electronic Cigarettes

University of Vermont·interventional·Posted Jul 1, 2021·Updated May 22, 2025

In Brief

A Phase 2 clinical trial evaluating Nicotine replacement therapy patch, Nicotine replacement therapy lozenge, and 2 other interventions for Nicotine Addiction and 2 related conditions. Completed, enrolled 396 participants across 1 site.

Detailed Summary

The overarching aim of this proposed randomized controlled trial (RCT) is to test nicotine replacement therapy (NRT) with text message support for two smoking cessation approaches among young adult dual users of combustible cigarettes (CC) and electronic cigarettes (EC). The investigators will use a 2x2 factorial design to randomize 390 participants to receive A) NRT plus text messages to quit CCs only, B) NRT plus text messages to quit CCs and ECs simultaneously, C) text messages alone to quit CCs only, or D) text messages alone to quit CCs and ECs simultaneously. The investigators primary outcome will be 7-day point-prevalence abstinence at the end of treatment (i.e., 3 months after randomization). The investigators will recruit participants using national advertising strategies. All treatment will be provided remotely in order to increase treatment access and comply with current COVID-19 restrictions.

Interventions

Nicotine replacement therapy patchdrug

The nicotine patch is attached to the participant's skin and provides a slight constant stream of nicotine. The smaller dose is meant to reduce nicotine dependence.

Nicotine replacement therapy lozengedrug

The nicotine lozenge contains small amounts of nicotine, which a participant slowly dissolves in their mouth. Like the patch, the smaller dose is meant to reduce nicotine dependence.

Quit electronic cigarettesbehavioral

Participants will receive instruction and text message support to quit electronic cigarettes when they quit combustible cigarettes.

Continue electronic cigarettesbehavioral

Participants will receive instruction and text message support to continue using electronic cigarettes after they quit combustible cigarettes.
