Older Adults Turning to Cannabis: Therapeutic Potential Shadowed by Growing Health Risks

While more seniors are seeking relief in cannabis, growing evidence points to potential dangers.

Why the cannabis craze is reaching older adults

Legal access and shifting perceptions have helped fuel cannabis use among adults 65 and older—from under 1 % in 2005 to 7 % in 2023—with many seeking relief for pain, insomnia, and anxiety.

Benefits remain largely anecdotal

Though users report better sleep and pain relief, clinical evidence remains sparse. Experts caution that older people process THC differently, and modes like edibles can be risky.

Health complications are rising

Cannabis-related ER visits and hospital admissions among older adults are climbing. One study found cannabis-related acute care tied to a 23 % higher risk of dementia diagnosis within five years, compared to non‑cannabis patients.

Cardiovascular and cognitive concerns

Cannabis may impair vascular health—akin to tobacco use—and could trigger heart issues, especially in older users with preexisting conditions.

Dependency and dosage dangers

Older veterans using cannabis show rising rates of cannabis use disorder. With THC products now far more potent, dosing missteps—such as consuming multiple 10 mg gummies instead of starting low—have led to anxiety, palpitations, and emergency visits.

Expert guidance: proceed with caution

Geriatricians advise “start low, go slow”—begin with 1–2.5 mg THC. They emphasize discussing use with doctors to monitor interactions with medications and avoid falls, dizziness, or cardiac effects.
