Introduction:
E-cigarettes are the most frequently used tobacco product among adolescents and young adults. Over 40% of adolescents who used E-cigarettes tried quitting in 2023, but few programs support them, particularly on social media. The aim of this study was to test the efficacy of E-cigarette cessation support groups on Instagram in an RCT.
Study Design:
A total of 500 participants were randomized to intervention or active control with baseline, 5-week (end of program), and 3- and 6-month follow-up surveys in 2022-2024.
Setting:
Healthy volunteers in California were recruited through social media advertisements.
Participants:
Participants reported the age of 13-21 years, English literacy, using social media at least 4 days per week, using E-cigarettes at least weekly, access to device with photo capability, and considering quitting within 6 months.
Interventions:
Instagram direct message support groups for 5 weeks provided motivational interviewing, social support, skill building, and group quit attempts. Controls were referred to state quitline resources, including telephone, online, texting, or mobile app.
Main Outcome:
A 7-day point prevalence abstinence from E-cigarette use.
Results:
Data were analyzed in 2024-2025. Mean age was 18.9 years, 39.8% were female, and 51.2% were male; 41.1% were White, 17.2% were Hispanic, and 27.4% were multiracial; 35.1% were sexual minority. A total of 70.4% used E-cigarettes daily, and 78.2% used within 30 minutes of waking. Retention rates were 43.6% at 5 weeks, 23.0% at 3 months, and 28.0% at 6 months. Generalized linear mixed models in a time-averaged difference approach examined 7-day point prevalence abstinence accounting for repeated measures and clustering effects. Intention-to-treat (ITT) analysis counting missing as vaping found greater abstinence in the intervention group (18.2% vs 11.8%) (OR=2.15, 95% CI=1.1, 4.2, p=0.025). Complete case analysis also found greater abstinence over 6 months for intervention (53.9%) than for control (40.4%) (OR=2.07, 95% CI=1.21, 3.52, p=0.008). There were no differences in vaping reduction, attitudes, or use of evidence-based methods. Intervention participants reported higher social support with no difference in overall program evaluation.
Conclusions:
Social media support groups were acceptable to diverse young people and improved abstinence rates on average over 6 months compared with quitline referral.
Trial Registration:
This study is registered at Clinicaltrials.gov (Protocol Number NCT04707911).

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
