As more and more U.S. states expand marijuana legalization, and with weed usage on the rise, doctors and advocates are warning about a little-known condition affecting heavy users of the drug.
Cannabinoid hyperemesis syndrome, or CHS, causes severe abdominal pain, nausea and “cyclic vomiting” among regular marijuana users — and can lead to extreme dehydration and, in rare cases, death.
“It’s very underdiagnosed,” said Dr. Joseph Habboushe, an assistant professor of emergency medicine at New York University Langone/Bellevue Medical Center, who co-authored a 2018 study on CHS. “Doctors aren’t thinking about it. Patients show up to the ER at an average of seven times before they’re diagnosed and have it for many years before it’s diagnosed.”
