The Centers for Disease Control and Prevention (CDC) released a report [August 6, 2026] showing a 3.7-fold increase in emergency department visits for Cannabinoid Hyperemesis Syndrome (CHS), a severe condition linked to chronic ma*****na use.
The sudden spike in recorded cases is primarily due to a new medical diagnostic code introduced in October 2025, which allowed hospitals to accurately track CHS rather than misdiagnosing it as general nausea or stomach flu.Key Findings from the CDC ReportAccording to the CDC's Morbidity and Mortality Weekly Report (MMWR), researchers tracked data from 7,500 healthcare facilities:The Spike: CHS-related ER visits jumped from 3.35 per 10,000 visits in September 2025 to 11.26 per 10,000 visits in October 2025 immediately after the code implementation.
Historical Underestimation: Between January 2023 and September 2025, nearly 200,000 CHS visits occurred, but the trend line appeared flat due to fragmented tracking.Affected Demographics: The highest rates of CHS visits occurred among young adults aged 15β24, females, Black individuals, and American Indian/Alaska Native populations.
Understanding Cannabinoid Hyperemesis Syndrome (CHS)Experts emphasize that while cannabis use is rising, CHS remains an agonizing risk for a specific subset of daily or heavy consumers.
Symptoms:
Characterized by cyclic, uncontrollable vomiting, severe nausea, and intense abdominal pain.Complications: Can lead to dehydration, kidney failure, heart-rhythm issues, or seizures if left untreated.
The Only Cure: While ERs can stabilize patients with IV fluids, completely stopping cannabis use is the only way to permanently cure CHS.CDC officials note that the high prevalence among teenagers and young adults highlights an urgent need to study the impacts of high-potency THC products like vapes, concentrates, and gummies.
