The MARY-JANE Cannabis and Heart Rhythm Trial

Despite recreational cannabis now being legal in 23 states, where more than 100 million Americans reside, studies on the actual health effects are limited. This study is a randomized trial, where each participant will be instructed to consume or avoid cannabis on randomly assigned days during a 14-day monitoring period. The goal of this study is to answer the question: "Does cannabis use increase the frequency of 'early' and abnormal heart beats?" During the 14-day period, participants will wear an external heart monitor, a glucose monitor, and a fitness tracker to track heart rhythm, glucose levels, step counts, and sleep health. Participants will use a mobile app or a text messaging service for daily instructions/reminders on cannabis use, and short surveys. The investigators ask that participants smoke or vape cannabis at least once on days they are instructed to consume cannabis. Compelling evidence of heart and other health effects would be important to the clinical care of our patients.
