Core tip: Cannabinoid hyperemesis syndrome (CHS) can be diagnosed with characteristic clinical features, including long-term cannabis use, severe cyclical abdominal pain, nausea and vomiting, and temporary relief of symptoms with hot showers or baths. Excellent long-term prognosis of CHS can be achieved when abstinence from cannabinoid is maintained. Physicians should have a high index of suspicion in patients with unexplained chronic abdominal pain and vomiting.
