Official title
Switching to a Vaping Device: Evaluating Risk Reduction Among Quitline Treatment Failure
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The overall aim of the study is to evaluate the provision of e-cigarette (EC) versus NRT on smoking behavior, product use patterns and continued use, and iCO, a biomarker of toxicant exposure, among a sample of recent QL treatment failures. We will randomly assign N=372 smokers (targeted accrual) to EC (n=186) or QL treatment as usual with combination nicotine replacement therapy (NRT; n=186). All participants will receive three calls from QL coaches and EC and NRT will be provided at no cost for 8 weeks. The final follow-up will occur 12-weeks post baseline.
