Cannabinoid Hyperemesis Syndrome

A rare condition in long-term heavy cannabis users characterized by cyclic nausea, vomiting, and abdominal pain.

Cannabinoid Hyperemesis Syndrome, or CHS, is a condition that affects a small subset of long-term, heavy cannabis users. It is characterized by recurring episodes of severe nausea, vomiting, and abdominal pain that can last for hours or days. The condition was first described in medical literature in 2004 by Australian researchers.

Symptoms and Patterns

CHS typically presents in three phases. The prodromal phase involves morning nausea and abdominal discomfort that can last for weeks or months. The hyperemetic phase features intense, uncontrollable vomiting and the characteristic compulsive hot bathing or showering, which temporarily relieves symptoms. The recovery phase follows cessation of cannabis use, with symptoms typically resolving within days to weeks. The hot water relief response is so distinctive that emergency physicians use it as a diagnostic indicator.

Treatment and Prevention

The only proven treatment for CHS is complete cessation of cannabis use. Symptoms typically return if cannabis consumption resumes. CHS is believed to be caused by the accumulation of cannabinoids in the body over time, potentially disrupting the normal function of CB1 receptors in the gut. While CHS affects only a small percentage of cannabis users, it is important for heavy, daily consumers to be aware of. If you experience recurring nausea, vomiting, and find that hot showers are the only relief, consult a healthcare provider and consider whether CHS may be the cause.
