A 23-year-old woman was throwing up uncontrollably for two years — until doctors discovered she had a mysterious cannabis-related syndrome

• A 23-year-old woman with diabetes faced bouts of nausea and vomiting for two years.
• The patient's symptoms only stopped when she took hot baths.
• Doctors diagnosed her with cannabinoid hyperemesis syndrome — a side effect of smoking weed.

The 23-year-old woman arrived at the hospital and could not stop vomiting — again.

For almost two years, the young woman had visited the emergency department nearly every month with the same symptoms: nausea, abdominal pain, and throwing up uncontrollably.

Doctors initially thought the patient's woes were caused by gastroparesis, a condition where the stomach doesn't empty properly. The digestive disorder commonly affects people with diabetes, which this patient had.
