An emergency room physician in Antigonish, N.S., is raising the alarm about a "paradoxical response" to marijuana that can exacerbate the very symptoms some people use the drug medicinally to address. When it occurs, it is typically in chronic consumers of marijuana, meaning those who use on a daily basis for more than a year. "These patients are coming in with severe, severe cyclic episodes of colicky abdominal pain with nausea and vomiting." The only real way to cure cannabinoid hyperemesis syndrome, Allen said, is to stop using marijuana entirely. She said marijuana is "marketed as a benign cure-all with little attention being paid to the unintended consequences."
