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:
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).

| T-Break Guide | Behavioral | The T-Break Guide was designed to help people complete a 21-day break from cannabis. For each day of the break, the Guide offers inspiration in the form of a quote, reflections based on likely experiences occurring at that point during the break, advice on ways to overcome challenges, alternative activities in which to engage, and encouragement.
The T-Break Guide follows the Motivational Interviewing principles of affirmation and autonomy. |
