From Chronic Cannabis to Cyclic Chaos: A Glimpse Into Cannabinoid Hyperemesis Syndrome.

Cannabinoid hyperemesis syndrome (CHS) pathophysiology remains largely unknown, and it is often misdiagnosed. This paper identifies the clinical causes of CHS, outlines diagnostic and therapeutic approaches, and emphasizes early detection, comprehensive treatment, and timely intervention for improved patient outcomes. This case describes a 38-year-old male with a known history of cannabis use who experienced repeated episodes of intense vomiting, nausea, and abdominal pain consistent with symptoms of CHS. He was initially misdiagnosed with other gastrointestinal conditions despite the knowledge of marijuana ingestion. The diagnosis of CHS was initially missed; however, after further examination and consideration of his marijuana use, CHS was correctly identified. The patient's symptoms improved after the cessation of marijuana use. This case illustrates the diagnostic difficulties of cannabinoid hyperemesis syndrome (CHS) in cannabis users with significant gastrointestinal symptoms. The early detection and cessation of marijuana use are crucial for symptom management and resolution, emphasizing clinical awareness and personalized treatment.
