Prevalence and Correlates of Symptoms of Cannabinoid Hyperemesis Syndrome in the United States

A small but significant number of US adults with daily cannabis use reported symptoms consistent with CHS. Beyond patterns of cannabis use, those with CHS symptoms had fewer economic resources and endorsed more cannabis-related problems, even when compared to others with daily cannabis use. Most people reporting CHS symptoms were not diagnosed by a medical provider, suggesting that there may be a substantial cohort who is experiencing CHS symptoms but is not seeking medical treatment or having their condition recognized by medical providers. As cannabis use increases, it is likely that CHS will also become more common, underscoring the importance of expanded research on this condition.
