MedPage Today (7/14, Henderson) reports a study found that U.S. “emergency department (ED) visits for cannabis hyperemesis syndrome (CHS) among adolescents increased more than 10-fold in recent years, with increases observed regardless of states’ recreational cannabis legalization (RCL) status.” Researchers said that “from 2016 through 2023, CHS encounters among 13- to 21-year-olds increased by 49% per year, from 160.4 per million ED visits in 2016 to 1,968.3 per million in 2023.” Further, “CHS encounters increased by 32.5% per million ED encounters per year in states with RCL and by 49.3% per million per year in states without RCL.” They noted the “overall rate per million ED encounters for CHS was 1,909.5 in states with RCL and 834 in states without RCL.” The study was discussed in a research letter in JAMA Network Open.
