Doctors warn that cannabinoid hyperemesis syndrome, or scromiting, is very real and getting more common among cannabis users.

CHS is an unpleasant side effect of a person’s plan to chill out with their favorite cannabis product of choice. After years of heavy cannabis use, a small but growing number of people will suddenly find themselves experiencing waves of nausea, abdominal pain, and vomiting so violently that it’s accompanied by a terrifying scream, hence the nickname “Scromiting” — a screaming vomit.
