Cannabinoid Hypermesis syndrome (CHS)

National Geographic has highlighted the rise of Cannabinoid Hyperemesis Syndrome (CHS), a condition linked to regular cannabis use

Key points about CHS from National Geographic and other sources:
• Symptoms: CHS is characterized by recurring episodes of severe nausea, vomiting, and abdominal pain. Some individuals also experience compulsive bathing behaviors, finding temporary relief in hot showers or baths.
• Cause: CHS is associated with frequent and long-term cannabis use, particularly heavy daily use or multiple instances of use per day over several years.
• Prevalence: While CHS was first described in 2004, cases have been on the rise, potentially due to increased accessibility of cannabis and higher THC potency in modern strains. Emergency department visits for CHS doubled between 2017 and 2021 in the U.S. and Canada, according to research cited by National Geographic.
• Risk Factors: Heavy cannabis use is the primary risk factor for CHS. It's important to note that most daily cannabis users do not develop CHS.
• Treatment: The only definitive treatment for CHS is the cessation of cannabis use. Supportive care, including intravenous fluids and antiemetics, may be needed for severe cases.
• Research: The mechanisms behind CHS are not fully understood, and researchers are investigating the role of the endocannabinoid system, potential genetic predispositions, and other factors that may contribute to the condition. 
​In summary, National Geographic and other sources highlight Cannabinoid Hyperemesis Syndrome as a potentially serious health consequence of frequent and long-term cannabis use. While research is ongoing, cessation of cannabis use is currently the only known way to effectively manage the condition.
