There’s mounting evidence that a new syndrome is directly related to chronic abuse of marijuana.
The severe vomiting sickness, called "cannabinoid hyperemesis," was first recognized in Australia in 2004.
U.S. researchers have uncovered a new case involving a 22-year-old man from Omaha, Neb, according to a study published in the March issue of the World Journal of Gastroenterology.
The latest findings were presented by Dr. Siva Sontineni and colleagues from the Creighton University Medical Center in Omaha, Neb.
Symptoms include nausea, stomach pain and severe vomiting. Sufferers report the only way to get some relief is from taking a hot bath or shower.
“Doctors and health care workers currently under recognize the syndrome leading to delayed diagnosis and expensive diagnostic investigations,” Sontineni wrote in the report.
“Increasing consistent use of marijuana among United States populations, particularly young people, over several years will see a steady rise in the number of cases diagnosed each year.”
In the Nebraska case, the man had been smoking heavy doses of marijuana daily for six years. This eventually led to bouts of vomiting lasting 2-3 hours daily, and it was worse after meals, the Australian Associated Press reported.
Scientists are still trying to figure out why these symptoms appear and why they appear only after several years of marijuana abuse.
