Reports have shown a staggering increase in cannabis-related emergency department (ED) visits in recent years. In 2011, the Substance Abuse and Mental Health Services Administration (SAMHSA) and Drug Abuse Warning Network (DAWN) estimated a total of 1.25 million illicit-drug–related ED visits across the US, of which 455,668 were marijuana related.2 A similar report published in 2015 by the Washington Poison Center Toxic Trends Report showed a dramatic increase in cannabis-related ED visits.3 In states with recent legalization of recreational cannabis, similar trends were seen.
