Study Summary

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.

Primary Outcome

Self-Reported 7-day Point Prevalence Abstinence from Cigarettes to assess complete product switching/substitution.
