A new paper in JAMA Pediatrics finds that a small number of children are showing up in Colorado emergency rooms having unintentionally ingested marijuana. It seems they are gobbling up their grandparents' medical-marijuana candy. The paper is gated but Medical News Today summarizes:
As background information, the authors, from the Rocky Mountain Poison and Drug Center, Denver, explained that medical marijuana has higher levels of tetrahydrocannabinol (THC) than when used recreationally. They added that medical marijuana is sold in candies, soft drinks and baked goods. ... There is concern that parents/grandparents may not disclose their use of medical marijuana because of the perceived stigma associated with the drug.
