Cannabis Syndrome Rises: Young Users Affected

Cannabis hyperemesis syndrome (CHS), a condition characterized by excessive vomiting and severe abdominal pain, is increasingly prevalent in the United States. First identified two decades ago in Australia, CHS is now frequently observed in emergency departments across the U.S.

Recent reports indicate a significant rise in CHS cases, with emergency department visits in Virginia alone increasing by almost 29% since 2020. Similar spikes have been noted in Massachusetts, Northern California, and parts of North Carolina, underscoring the growing public health impact of this syndrome.

While CHS has traditionally been associated with chronic, long-term marijuana users, a recent CDC report reveals a concerning trend: higher proportions of emergency department visits involve younger individuals. Patients aged 15 to 24 now represent the highest average proportion of monthly visits, with rates dramatically increasing after CHS received a dedicated diagnostic code in October.

Experts theorize that this rise among younger users may be linked to earlier initiation of cannabis use, vaping, and the increasing potency of THC products. The syndrome typically progresses through three phases: prodromal (morning nausea and pain), hyperemetic (overwhelming vomiting, often eased by hot showers), and recovery (symptom disappearance upon cessation of cannabis use).

Effective treatment for CHS ultimately requires abstinence from cannabis products. Health officials emphasize the need for increased awareness among healthcare providers and the public regarding CHS and its potential causes, particularly the role of high-potency cannabis. Patients experiencing symptoms are advised to consult a doctor.
