A newer disease from use of marijuana is called CHS (Cannabinoid hyperemesis syndrome) CHS is characterized by cyclic episodes of nausea and vomiting. Hot showers seem to be the only remedy for those suffering. Physicians say that patients will come to the emergency room 3 or 4 times before getting a correct diagnoses, because the symptoms are not much different than other common stomach bugs. Dr. Kennon Heard, an emergency room doctor in Colorado, says that instances of CHS have skyrocketed since the state legalized marijuana. Since CHS was only discovered in the last decade, no one knows for sure how many Americans suffer from this disorder.
