Proper counseling for diagnosis and management of cannabinoid hyperemesis syndrome: a case report

To confirm the diagnosis of CHS, counseling should specify the need for a minimum of 3 months of cannabis cessation to achieve symptom relief. Increased physician and patient awareness of this minimal time period for drug cessation can help to avoid unnecessary investigations, and prolonged patient suffering. This case emphasizes the need for vigilance in recognizing CHS and consideration of cannabis as a potential cause of cyclic vomiting.
