INTRODUCTION:Chronic cannabis use had been associated with hyperemesis. We sought to determine whether cannabis liberalization contributed to increased hospitalizations for hyperemesis.METHODS:Cannabis use and admissions for hyperemesis in legalized states were compared with those of nonlegalized states, before and after cannabis legalization, using state inpatient databases.RESULTS:From 2011 to 2015, cannabis use increased 2.2 times in legalized states and 1.8 times in nonlegalized states. The odds of presentation with hyperemesis were higher in 2015 compared with those of 2011 in all states.DISCUSSION:Recreational legalization may be contributing to rising cannabis use. Hospitalizations for hyperemesis have also increased but did not seem to be solely due to cannabis legalization.
