Suspected Cannabinoid Hyperemesis ER Visits Among Youth Rose 28% Per Year
Suspected CHS-related emergency department visits among Americans aged 15-24 increased by an average of 28.1% annually from 2006 to 2020.
Quick Facts
What This Study Found
Using the Nationwide Emergency Room Sample, over 55,000 suspected CHS-related ED visits were identified among youth (ages 15-24) between 2006 and 2020, with an average annual increase of 28.1%. Males, those in the western U.S., and those with public insurance were more likely to present with suspected CHS.
Key Numbers
Over 55,000 suspected CHS-related ED visits identified. Average annual increase of 28.1% per year from 2006 to 2020. Higher rates in males, western U.S., and public insurance holders.
How They Did This
Retrospective analysis of the Nationwide Emergency Room Sample (2006-2020) identifying suspected CHS-related visits among youth aged 15-24.
Why This Research Matters
The rapid growth in CHS-related ER visits among young people parallels rising cannabis potency and use rates, highlighting an emerging clinical burden that emergency departments need to prepare for.
The Bigger Picture
The 28.1% annual increase in suspected CHS visits far outpaces the growth in cannabis use itself, suggesting that increasing potency, frequency of use, or better recognition may be driving the trend.
What This Study Doesn't Tell Us
Uses suspected rather than confirmed CHS cases, which may include other causes of cyclic vomiting. Administrative data lacks clinical detail. Cannot confirm cannabis use patterns in individual patients. ICD coding changes over the study period may affect trends.
Questions This Raises
- ?How much of the increase reflects better recognition versus a true rise in CHS incidence?
- ?Is the high-potency cannabis now available driving CHS rates disproportionately?
