Summary
Introduction:
This text provides an analysis of the correlates of e-cigarette (EC) use among adults seeking smoking cessation treatment. The study also examines the impact of baseline EC use on smoking cessation outcomes. The key points summarize the study design, participant characteristics, and major findings. The main message highlights the implications of the study for regulatory matters.
Key Points:
* The study included 649 adult smokers enrolled in smoking cessation treatment.
* Participants completed a baseline assessment and follow-ups at 4-, 12-, and 26-weeks after a scheduled quit date.
* At baseline, 66.6% of participants had ever-used ECs, and 23.1% reported past 30-day EC use.
* Past 30-day EC users were younger, more socioeconomically disadvantaged, more CC dependent, and less likely to report Black race compared to non-users.
* At the 4-, 12-, and 26-week follow-ups, 6.4%, 7.4%, and 8.1% reported dual EC/CC use, respectively.
* Past 30-day EC use at baseline was not associated with CC cessation at any follow-up.
* Among past 30-day users, using ECs ≥ once per week was associated with a lower likelihood of CC cessation at 26-week follow-up.
Main Message:
This study highlights the need for further research on the impact of EC use on smoking cessation outcomes. The findings suggest that more frequent EC use at baseline may adversely impact longer-term cessation outcomes, particularly among those with greater baseline CC/nicotine dependence. Regulators should consider these findings when developing policies related to EC use and smoking cessation treatment. Additionally, healthcare providers should be aware of the potential impact of EC use on smoking cessation outcomes and provide appropriate advice and education to patients.
