Abstract

Background: Current literature is scarce in documenting marijuana use after bariatric weight loss surgery (WLS). Objectives: The objective of this study was to explore the association among marijuana use patterns, disordered eating, and food addiction behaviors in patients 2 years after WLS. Setting: A university hospital in the United States. Methods: Participants (N = 50, mean age 28 y, standard deviation = 5.8) were administered a structured assessment that included the Addiction Severity Index, Yale Food Addiction Scale, Eating Disorder Examination Questionnaire, and Disordered Eating Questionnaire. Marijuana use was defined based on the Addiction Severity Index as current use (within 30 d), recent use (use in last year), and increased use (increased use since surgery). Data were analyzed using Fisher's exact tests and linear regression methods adjusting for age, gender, race/ethnicity, time since surgery, and change in body mass index. Results: The majority of the sample was female (76%) and underwent Roux-en-Y gastric bypass (62%). Eighteen percent (18%) of the sample reported current marijuana use; 38% reported recent use; and 21.4% reported increased use post-WLS. A loss of controlled food intake was associated with current (P = .02) and increased post-WLS use (P = .01). Increased use and/or regular marijuana use predicted higher scores on eating disorder subscales compared with respective counterparts (P < .05). Current use did not significantly predict higher scores on the Yale Food Addiction Scale. Conclusions: Findings indicated marijuana use in post-WLS patients despite recommendations against use. A subgroup of WLS patients may be at risk for disordered eating post-WLS, particularly those who used marijuana before surgery, and should be closely monitored for several years post-WLS.
