Doctors are warning about a fast-growing health problem linked to frequent marijuana use. A condition called cannabis hyperemesis syndrome (CHS) is sending more long-term users to the hospital. It has become so intense in some cases that people cry out in pain while vomiting — a combination doctors have nicknamed “scromiting.”

CHS usually affects people who use cannabis daily or almost daily. Symptoms can start within 24 hours of using the drug and include nonstop nausea, severe stomach cramps, and vomiting several times an hour. Emergency room records show that cases have increased more than fourfold in just six years.

Experts believe the rise may be connected to modern cannabis products, which contain far more THC than those from earlier decades. Many patients don’t realize marijuana is the cause, especially if they have used it for years without issues. As a result, they often return to the ER multiple times before getting the correct diagnosis.

Doctors still aren’t sure why CHS happens, but they suspect the drug overstimulates the body’s systems that control nausea and vomiting. Without treatment, CHS can lead to dehydration, weight loss, throat injury, and other serious complications. Hot showers may offer brief relief, but there is no official medical treatment.

Health professionals agree on one proven solution: stop using cannabis completely. Symptoms typically fade after quitting, though it may take several weeks.

With marijuana now legal in many states, doctors say CHS could become an even bigger public health concern.
