What this trial studies

This clinical trial evaluates the effectiveness of a combination of nicotine patches and mouth spray compared to a nicotine tapering plan for vaping cessation. Conducted in New Zealand, it aims to determine which method, along with behavioral support, leads to higher rates of vaping abstinence after six months. Participants will be randomly assigned to one of the two treatment groups and will receive written support to aid their quitting efforts. The study targets individuals who vape regularly and are motivated to quit within the next eight weeks.

Why it matters

Potential benefit: If successful, this approach could significantly improve the chances of long-term vaping cessation for participants.

How similar studies have gone: Previous studies on nicotine replacement therapies have shown promise, but this specific combination approach is novel and has not been extensively tested.
