The National Syndromic Surveillance System is a CDC surveillance system which allows timely detection of emergency department trends by matching chief complaint text or diagnosis codes and text to established syndrome criteria. Although events such as accidental and over-consumption of edible marijuana products are an emerging concern, no CDC syndrome definition currently exists for marijuana-related visits. We developed and evaluated a marijuana syndrome definition using data from 15 hospitals in Adams, Arapahoe, Denver, and Douglas counties reporting to NSSP.
