Colorado doctors say looser pot laws are leading to more child poisonings for youngsters who are often attracted by drug-laced edibles like gummy worms or brownies.
From early 2005 to late 2009, Children's Hospital Colorado had no emergency-room visits by kids who had ingested marijuana. In the following two years, after medical marijuana became legal in Colorado, it had 14 cases. So far, no deaths have been reported.
Doctors are campaigning for mandatory safety packaging as Colorado lawmakers debate even broader legal sales of pot with recreational-marijuana stores.
"We've seen a dramatic increase in pediatric exposure," said Dr. George Wang, a Children's ER doctor who also works with Denver Health's Rocky Mountain Poison and Drug Center.
