Increased rate of calls to poison control centers for cannabis exposure among children. Most of the increase-which occurred between 2017 and 2019-was associated with edible cannabis products. Using data from the National Poison Data System, researchers in the March 22 online Pediatrics found an overall increase of 31%, with an increase of 26% in edible products and 6% in nonedible products. These findings are not unique; earlier studies conducted in Washington, Colorado, and Massachusetts-among the first states to legalize marijuana-found significant increases in cannabis exposure among children before and after marijuana legalization, with the greatest increase for edible products. As legalization of marijuana continues across the country, researchers recommend close surveillance of its effects and improved preventive measures to keep cannabis products away from children.
