CHS episodes typically occur within 2 4 hours of cannabis use and can last for several days. What makes the condition especially troubling is that traditional anti-nausea medications often fail to provide relief.
Patients frequently report cyclical episodes. One man was admitted to the emergency room four or five times within six months. He described a “burning” and “agonizing” pain centered in his abdomen, accompanied by relentless vomiting. Many CHS patients attempt to self-soothe with extremely hot showers — a behavior so common it’s considered a hallmark of the condition. In his case, the pain was so severe that he required morphine for relief.
Another individual compared the sensation to childbirth, calling it “some of the worst physical pain I’ve ever experienced in my life.” During episodes, she said she found herself pleading for the pain to stop.
“Because the syndrome strikes intermittently, some cannabis users assume a recent episode was unrelated and continue using — only to become severely ill again,” explained Dr. Beatriz Carlini, research associate professor at the University of Washington School of Medicine.
