Using virtual reality to assess and treat tobacco addiction

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This project aims to enroll 200 daily tobacco users aged 22 and older from the San Diego area to evaluate the effectiveness of varenicline in reducing nicotine cravings. Participants will undergo a virtual reality nicotine cue exposure assessment and will be randomized to receive either varenicline or a placebo. After an eight-day titration period, participants will be reassessed using the same virtual reality paradigm and followed up with mobile assessments for short-term nicotine use behaviors over 30 days. The study seeks to establish a connection between virtual reality assessments and treatment outcomes for tobacco use disorder.
