In Canada, cannabis poisonings rose sharply among people 65 and older after the country legalized the drug, a new study found.
As more places legalize marijuana, policymakers and health officials have worried about the health risks that the drug may pose to adolescents. But a new study suggests that an additional demographic is at risk: seniors.
The study, published Monday in JAMA Internal Medicine, found that after Canada legalized marijuana, the number of emergency room visits for cannabis poisoning rose sharply among people ages 65 and older. Poisonings doubled after Canada legalized sale of the cannabis flower, and then tripled just 15 months later, when Canada legalized the sale of edibles.
