Cannabis Hyperemesis Syndrome (CHS) is an increasingly recognized condition affecting long-term, heavy cannabis users. It causes recurring episodes of intense nausea, abdominal pain, and uncontrollable vomiting—sometimes referred to as “scromiting,” a combination of screaming and vomiting due to the severity of symptoms.

First identified in the early 2000s, CHS remained a medical mystery for years. Many patients experienced repeated emergency room visits before healthcare providers made the connection between their symptoms and chronic cannabis use.

One distinctive feature of CHS is that symptoms often temporarily improve with hot showers or baths, which has become a key diagnostic clue. Some patients also report relief from topical capsaicin cream, though these measures are not cures.

Treatment options are limited. Traditional anti-nausea medications are largely ineffective, and the only proven long-term solution is complete cessation of cannabis use. This can be challenging due to dependence and the widespread belief that cannabis is harmless.

Emergency departments across the United States are reporting a sharp rise in CHS cases, likely driven by increased cannabis potency and broader access following legalization. Individuals who use cannabis daily or near-daily, begin use during adolescence, or consume it long term are at significantly higher risk.

From a public health perspective, CHS underscores the need for improved education, greater physician awareness, and clearer regulation. Many users are unaware that cannabis can cause such severe physical illness. The condition also complicates the narrative of cannabis as a universally “safe” substance, raising important questions about potency limits, labeling, and consumer guidance in legal markets.
