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)

Cannabis Use Tolerance Cannabis Withdrawal Behavioral: T-Break Guide

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).

Behavioral: T-Break Guide

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 first week focuses on physical symptoms of cannabis withdrawal (e.g., sleep, appetite).
  • The second week focuses on the emotional experience (e.g., anxiety, boredom).
  • The third week focuses on behavioral aspects (e.g., examining patterns, connections).

The T-Break Guide follows the Motivational Interviewing principles of affirmation and autonomy.

Primary Outcome Measures :
  1. Tolerance Break Completion [ Time Frame: 21 days ]
    Did the participant go 21 days without using cannabis? Self-report, "yes/no" question on followup survey


Secondary Outcome Measures :
  1. Cannabis Use After 21 Days [ Time Frame: 21 days ]
    How much cannabis are participants using after 21 days break? Followup survey question, 5 point Likert scale with "way more; a little more; same; a little less; way less" as response options

  2. Confidence in Future Break [ Time Frame: 30 days ]
    Participants' confidence level about how successful they would be taking a future break

  3. Important of Balance [ Time Frame: 30 days ]
    Participants' importance with finding/keeping balance in cannabis use going forward

  4. Alcohol and Other Drug Use During Break [ Time Frame: 30 days ]
    What happened to participants' alcohol and other drug use while stopping cannabis? Self report by category of substance, asking use prior and change (if any) during break

  5. Future Cannabis Use [ Time Frame: 30 days ]
    After taking a break, where do participants' picture their cannabis use in 3 years? Followup survey question, "Where do you picture your cannabis use 3 years from now" {"a lot more; a little more; about the same; a little less; a lot less; none}
