For daily marijuana users seeking relief from nausea, doctors now say that using too much for too long can have the opposite effect in rare cases — triggering abdominal cramping, vicious vomiting and an overwhelming urge for a hot shower.
That leads to a condition that has been likened to the morning sickness associated with pregnancy, said Susan Smolinske, managing director at the Children's Hospital of Michigan Regional Poison Control Center.
"Marijuana typically causes the munchies, right? This is the anti-munchies," she said. And a sufferer's scramble for the tub? "The thinking is that a hot shower gives some feedback that resets temporarily the autonomic system," Drake said.
Identified only in recent years, the condition seems to be rare, affecting only long-term daily users, according to medical literature.
At the Kalamazoo-based Michigan Holistic Health, clinicians have seen no cases among about 13,000 clients, said registered nurse Annette Crocker who, with her husband, Dr. David Crocker, runs the clinic.
