Vaping Cessation

The purpose of this study is to pilot test feasibility and acceptability of the Quit the Hit Toolkit, a social media-based nicotine vaping cessation program for adolescents and young adults, adapted for use in community settings.

The goal of this randomized controlled study is to test if this new intervention works to help adolescents quit vaping. A key feature of the program is the use of peer support for parents, delivered by trained parent coaches. Participants will complete baseline and follow up surveys. Parents in the intervention arm will receive peer support as part of the program.

This will be a multi-center, double-blind, randomized, placebo-controlled, Phase 3 study conducted in male or female adults who are daily nicotine e-cigarette users only. A total of approximately 800 subjects will be randomly assigned (1:1) to one of two Arms: * Arm B, 12 weeks cytisinicline + behavior support: N=400 or * Arm A, 12 weeks of placebo+ behavior support: N=400) The primary objective is to assess whether subjects randomized to Arm B (3 mg cytisinicline TID for 12 weeks plus behavioral support) have a higher probability of nicotine vaping cessation from Week 9 to Week 12 as compared to subjects randomized to Arm A (placebo TID for 12 weeks plus behavioral support).

The goal of this clinical trial is to evaluate the feasibility, acceptability, and preliminary efficacy of mindfulness-based interventions (MBI) as a vaping cessation intervention in young adults aged 18-29 who vape nicotine at least 25 days per month and are interested in cutting down or quitting. The main questions it aims to answer are: * Can mindfulness practice reduce nicotine cravings in young adults? * Is mindfulness practice an acceptable and feasible intervention for vaping cessation in this population? Researchers will compare participants in the mindfulness intervention group to a control group that watches a video with calming music and images to see if mindfulness practice has a greater effect on reducing nicotine cravings. Participants will: * Complete a baseline survey and craving cue reactivity assessment. * Engage in a 10-minute guided mindfulness meditation (intervention group) or view calming music and images (control group). * Rate their cravings and the acceptability, appropriateness, and feasibility of the intervention after the session.

This research focuses on maximizing the chances of successfully quitting vaping. A large, pragmatic community-based clinical trial is planned in New Zealand to build on existing evidence from previous vaping and smoking cessation research undertaken by the study team. The effectiveness of combination nicotine replacement therapy (NRT) compared to nicotine tapering on vaping abstinence has not yet been investigated, but both provide an opportunity to increase success with vaping cessation, especially when combined with written behavioural support to further boost quit rates. The planned trial will test whether using combination NRT will help more New Zealanders to quit vaping long-term, compared with a vape nicotine tapering plan. Participants in both groups will also receive written vaping cessation behavioural support.
