Participants in this randomized clinical trial will be methadone-maintained smokers interested in switching to electronic cigarettes (ECs). There will be a total of 7 study visits over the course of 6 weeks; each visit includes psychometric assessment and biomarker measurements. After completion of the baseline visit, participants will be randomized to either: 1) 6 weeks of EC use (JUUL 5% nicotine pods) or 2) 6 weeks of nicotine replacement therapy (NRT) in the form of nicotine lozenges. EC and NRT use will begin the day after the baseline assessment.
