(Science20) States that have decriminalized marijuana have also seen dramatic increases in children requiring medical intervention, according to research in the Annals of Emergency Medicine ("Association of Unintentional Pediatric Exposures with Decriminalization of Marijuana in the U.S.") which analyzed call volume to U.S. poison centers from January 2005 through December 2011.
The call rate to poison centers in states that decriminalized marijuana increased by more than 30 percent per year between 2005 and 2011, while the call rate in non-legal states did not change.
More pediatric exposures in decriminalized states than in non-legal states required medical evaluation, had moderate to major clinical effects and required critical care admissions. Neurologic effects were the most common. The most common therapy was administration of intravenous fluids. Aggressive interventions were rare and there were no deaths.
