The Disproportionate Rate of Acute Clinical Illness Associated with Cannabis Edible Use

Background: Cannabis-associated emergency department (ED) visits have risen due to increased availability of the drug in Colorado. Edible cannabis products have been associated with pediatric ED visits and emergency providers report a high incidence of edible related visits in adults. We sought to determine if edible cannabis products result in more ED visits than inhaled products when standardized for product availability.
Methods: This was a retrospective chart review study at a large academic hospital. Cases were identified by cannabis ICD-9 and ICD-10 codes. All ED visits with a cannabis ICD-9/10 code between January 1, 2012 and December 31, 2016 were reviewed. Rates of inhaled cannabis-attributed visits and edible-attributed visits were standardized by inhaled and edible product sales provided by the Colorado Department of Revenue over the study period.
Findings: There were 9,973 visits with an ICD-9 or ICD-10 code for cannabis use. 2,567 (25·7%) visits were deemed to be at least partially cannabis-attributable; 238 of those (9·3%) were related to edibles ingestion. When standardized for product sales, edibles had a cannabis-attributable ED visit rate 269 times the rate of inhaled cannabis. Inhaled cannabis-attributed visits were more likely to be for cannabinoid hyperemesis syndrome (p<0·0001) and patients with edible-attributed visits were more likely to be due to acute psychiatric symptoms (p<0·0001).
Interpretation: Inhaled cannabis-attributable visits are more frequent than edible cannabis-attributable visits though when standardized for sales data, edible cannabis products are associated with a higher rate of emergency department visits than inhaled products.
