title: Assessing marijuana use in bariatric surgery candidates: should it be a contraindication?
abstract: Research has demonstrated negative effects of both alcohol and tobacco use after bariatric surgery. However, no research to date has examined effects of cannabis use after bariatric surgery, even though cannabis is the most commonly used illicit drug in the USA. Literature review reveals that many practitioners generalize from data regarding alcohol abuse to all substances. Further, many screening protocols fail to differentiate between varying levels of cannabis use. The current report aims to (1) review the relevant literature on marijuana use and its potential consequences among bariatric patients, (2) discuss relevant problems and gaps in this literature, and (3) make preliminary recommendations regarding the assessment and treatment planning of bariatric candidates who disclose marijuana use.
