Feasibility and Acceptability of Switching to E-cigarettes Among Cigarette Smokers Engaged in SUD Treatment

The purpose of the proposed study is to examine the feasibility of integrating a smoking harm reduction program featuring provision of e-cigarettes and tailored instructions to switch into an existing substance use disorder treatment program. This longitudinal study includes three weeks of micro-surveys delivered via text messages to evaluate the intervention's feasibility and acceptability, gather initial effectiveness data, and understand participants' lived experience of smoking and vaping while engaged in substance use disorder treatment.
