Cannabis Edibles Causing Poisonings in Older Users

The legalization of cannabis and the rise in popularity of its edible forms have led to a concerning trend among seniors: an increase in emergency department visits due to cannabis overdoses.

A recent study conducted in Ontario, Canada, found that cases of “cannabis poisonings” among older adults tripled after the legalization of edibles, compared to the period before legalization. Dr. Nathan Stall and his team from Sinai Health and the University Health Network in Toronto analyzed data from the Ontario Ministry of Health on emergency department admissions for cannabis poisoning over three time periods.

The study revealed that there were over 2,300 emergency department visits for cannabis poisonings among older adults, with the average age being 69.5 years. The rate of emergency visits doubled during the initial legalization period and tripled after the introduction of edibles.

The researchers highlighted the lack of age-adjusted instructions for edibles, which may contribute to accidental ingestion among older adults. They also noted that seniors are at a higher risk of adverse effects from cannabis due to their age, potential drug interactions from multiple medications, and underlying health conditions.

Stall and his colleagues recommended that jurisdictions with legalized cannabis implement measures to prevent unintentional exposure in older adults and provide age-specific dosing guidance. As the popularity of cannabis edibles continues to grow, it is crucial to address the unique risks they pose to older adults.
