The medical and psychosocial impact of tobacco and alcohol have been investigated in bariatric surgery populations. Little, however, is known about marijuana and its impact on peri-operative risk and post-operative outcomes. Although previously published guidelines have suggested that substance use/abuse is a contra-indication for bariatric surgery, states vary in the legality of recreational and medicinal marijuana. This collaborative course will examine what is known about marijuana use in populations with obesity, the impact on surgical outcomes and implications for post-operative problematic use. Panelists will discuss implications for clinical practices.

Learning Objectives:

  1. Understand the impact of THC on appetite and weight
  2. Identify impact of marijuana use on peri-operative outcomes
  3. Review substance use literature in bariatric surgery populations and implications for marijuana use
