A new study reveals that modification of drug enforcement laws for possession of marijuana in Colorado has led to a rise in unintentional marijuana ingestion by children.

George Sam Wang, M.D, from the Rocky Mountain Poison and Drug Center, Denver, and colleagues compared the proportion of marijuana ingestions by young children who sought care in a children's hospital emergency department before and after the modification of drug enforcement laws in October 2009 regarding medical marijuana possession. A total of 1,378 patients younger than 12 years of age were evaluated for unintentional ingestions: 790 patients before September 30, 2009 and 588 patients after October 1, 2009.
"The proportion of ingestion visits in patients younger than 12 years (age range 8 months to 12 years) that were related to marijuana exposure increased after September 30, 2009, from 0 of 790 to 14 of 588," the authors report. "Eight of the 14 cases involved medical marijuana, and 7 of these exposures came from food products." The authors note most of the children were male and were admitted to or observed in the emergency department. "Because of a perceived stigma associated with medical marijuana, families may be reluctant to report its use to health care providers. Similar to many accidental medicinal pediatric exposures, the source of the marijuana in most cases was the grandparents who may not have been available during data collection."
"Physicians, especially in states that have decriminalized medical marijuana, need to be cognizant of the potential for marijuana exposures and be familiar with the symptoms of marijuana ingestion. This unintended outcome may suggest a role for public health interventions in this emerging industry, such as child-resistant containers and warning labels for medical marijuana," the authors conclude.
