Cannabis Tolerance Break Resource Study: T-Break Guide

Completed

Brief Summary: The purpose of this pilot study is to conduct research into the value of using the T-Break Guide for assisting people taking a tolerance break from cannabis. The hope is that this initial research will yield some insights and benchmarks into the Guide's efficacy, and provide a foundation for a later randomized control study.

The following are some key research questions:

1. How did participants use the Guide? (Eg: daily; read once; 'a la carte')

2. How did using the Guide increase fidelity to tolerance break (starting, continuing, completing a break)?

3. Did using the Guide yield any benefits beyond tolerance break fidelity? (Eg: insight into patterns of use)

Detailed Description: The pilot study used a pretest-posttest design in which participants completed a baseline survey and were asked to attempt a 21-day period of cannabis abstinence, to consider using the T-Break Guide (intervention) in their attempt, and to complete a follow-up survey after 30 days.

Participants were young adults aged 18-29 recruited through posters and tabling events at the University of Vermont (UVM), a post on a UVM webpage, emails on listservs of seven other universities, and a post on a subreddit focusing on responsible cannabis use. The posters and online announcements directed participants to the online baseline survey, which contained consent information before allowing participants to complete.

After completing the baseline survey, participants received a link to an online version of the T-Break Guide through email. After 30 days, participants received another email prompting them to complete the follow-up survey. The UVM Institutional Review Board reviewed and approved all study procedures (STUDY00001489).
