Cannabis Use Triggers Violent Vomiting Syndrome

Cannabinoid hyperemesis syndrome (CHS) is a serious complication for about 1 in 6 American adults who use cannabis regularly. This condition is marked by cycles of severe vomiting and intense abdominal cramping, distinct from typical stomach bugs. Emergency physicians describe it as an extremely debilitating experience for patients.

A telltale sign of CHS is the need for frequent hot showers or baths for temporary relief, a sensation that can temporarily override the nausea signals. Despite this, traditional anti-vomiting medications are often ineffective. The only definitive cure for CHS is discontinuing cannabis use.

Symptoms can be so severe that they lead to missed work, dehydration, kidney damage, and in critical cases, life-threatening esophageal tears. CHS is estimated to affect over 2.7 million Americans, with daily users at higher risk. However, it can also develop in those using cannabis as little as once weekly.

Many patients use cannabis for self-treatment of chronic pain or anxiety, making cessation difficult. The creation of a diagnostic code for CHS has improved tracking, with emergency department visits for the condition increasing significantly. Higher THC concentrations in modern cannabis products also contribute to rising risks.

While research into potential medical benefits of cannabis continues, there's a significant gap between public perception and scientific reality. Many users underestimate the documented harms, including CHS and cognitive issues, highlighting a need for greater awareness of these risks.
