Brief Summary:
This study will evaluate behavioral and psychological appeal, toxicity, and effect of e-cigarettes on smoking behavior and nicotine addiction in chronic smokers with serious mental illness (SMI) who have failed to quit smoking. A total of 240 participants will be enrolled and randomly assigned to either receive a supply of e-cigarettes for 8 weeks plus assessments (baseline & weeks 2, 4, 6, 8, 13, & 26) or assessments only. This single-blinded study will provide e-cigarettes and instructions on their safe use. Level of appeal will be inferred from carefully assessed use of e-cigarettes and reduction in combustible tobacco. Qualitative data will also be collected from participants assigned to e-cigarettes, given that unanticipated issues will almost certainly arise in connection with e-cigarette use that can only be captured within a qualitative debriefing at the conclusion of participants' time in the study.

Arm Intervention/treatment
Experimental: E-Cigarette
The E-cigarette arm will be asked to use e-cigarettes in place of regular tobacco products. The group will be assessed at baseline, 2 weeks, 4 weeks, 6 weeks, 8 weeks, 13 weeks, and 26 weeks.
Behavioral: E-cigarette
The e-cigarette arm will be provided with 8 weeks of free e-cigarettes based on self-report of regular tobacco use. Participants assigned in this arm will be asked to switch combustible tobacco with e-cigarettes. The appeal of e-cigarettes and health impacts will be measured, but we are not targeting quitting combustible tobacco or reducing craving.

No Intervention: Assessments only
The Assessment only group will be asked to refrain from use of e-cigarettes during participation. The group will be assessed at baseline, 2 weeks, 4 weeks, 6 weeks, 8 weeks, 13 weeks, and 26 weeks.
