Cases of cannabis poisoning increased after legalization and decriminalization of the drug, according to a new meta-analysis published in the journal, Addiction.
The combined results of thirty studies—which focused on legalization and decriminalization in the United States and Canada—estimate a more than three-fold increased risk of poisoning after it was legalized. Studies specific to children revealed an even higher number with episodes increasing almost four and half times the rate prior to the drug being legal.
