Cannabinoid hyperemesis syndrome, or CHS, is a little-known disease that's "caused by heavy, long-term use of various forms of marijuana." Symptoms of CHS include nausea and vomiting and for an "unclear reason" taking hot showers and baths seems to alleviate the pain. An emergency physician in Aurora, Colorado said that patients who suffer from CHS often come to the emergency room three to five times before they're accurately diagnosed. Since medical marijuana became legalized in Colorado in 2009, the cases of emergency room diagnosed CHS have doubled. As more states begin to legalize marijuana, doctors are eager to make sure CHS is on people's radar.

People who frequently use marijuana now face a new challenge other than anti-pot groups. A new marijuana-related illness is now on the rise.

Cannabinoid Hyperemesis Syndrome (CHS) is a chronic disease a marijuana user can acquire. CHS symptoms start with a series of recurrent nausea, vomiting, and crampy abdominal pain. It appears the that the main remedy for CHS symptoms is a hot shower.

The CHS symptoms are highly similar to common stomach bugs. Doctors said patient would need three to four check-ups or emergency room visits before they can get a correct diagnosis.

Lance Crower, a patient who suffers from CHS said, for nearly two years he went multiple times to an emergency room before getting an accurate diagnosis.

“The first question he asked was if I was taking hot showers to find relief. When he asked me that question, I basically fell into tears because I knew he had an answer,” Crowder told MSN.

CHS-disease-marijuanaPatients who suffer from CHS have increased in Colorado since the state legalized marijuana, said Dr. Kennon Heard, an emergency room doctor.

“It is certainly something that, before legalization, we almost never saw… Now we are seeing it quite frequently,” said Heard.

Dr. Eric Lavona, a Denver physician, said that CHS is not a serious disease. “These folks are really suffering. People can get pretty sick,” said Lavona.

There have been multiple reports of CHS incidents across the U.S. including District of Columbia.

Meanwhile, doctors and hospital staff in marijuana legal states are frequently getting a patient who suffers from CHS. Physicians said that patients in marijuana-free states are highly unlikely to get a correct diagnosis. Doctors often misdiagnose CHS because the symptoms resemble some stomach related disorders.

CHS was discovered in the last decade, experts are not sure how many marijuana users suffer from the disorder.
