- Senior medical cannabis patients are the fastest-growing demographic, with 25.8% of patients at a New York dispensary aged 65 or older and 34.5% aged 50–64, using cannabis primarily for chronic pain, anxiety, and insomnia.
- Cannabis potency today is roughly 10 times stronger than 50 years ago, making accidental overconsumption more likely for older users whose livers and kidneys process drugs less efficiently, Grinspoon warns.
- The war on drugs paradoxically drove THC concentrations higher because smuggling economics rewarded potency, while medicinal cannabinoids such as CBD were bred down, according to the author.
- The cannabis industry is split between roughly 10,000 small businesses the author calls ethical and large multistate operators that he likens to alcohol and tobacco companies for producing super-high-THC products and running ads that may appeal to adolescents.
- More than 20 million people, disproportionately Black and brown, have been arrested for simple cannabis possession, Grinspoon notes — while emphasizing that legalization must still proceed safely with physician and patient education.
- Grinspoon, an addiction specialist at Massachusetts General Hospital and author of 'Aging Well with Cannabis,' recommends starting patients on extremely low doses and creeping upward, often using non-intoxicating CBD alongside THC.
Why it matters: With roughly a quarter of medical cannabis patients at one New York dispensary now 65 or older, the gap between patient adoption and physician training has become a direct safety issue — especially as today's cannabis runs about 10 times stronger than what these users encountered decades ago. Grinspoon argues federal legalization is the lever that would standardize labeling and dosing guidance.
