Cannabis Use Among Older Adults: Risks and Facts

Topic: Health

Stanford experts warn about the risks of cannabis use among older adults. The drug is much stronger today than in the past, and regular use can lead to health problems.

Cannabis use is increasing among older Americans, but Stanford Medicine experts are warning that today's marijuana products are far more powerful than many people realize. This can come with significant health risks. Eloise Theisen, a geriatric nurse practitioner at Stanford Medicine, has seen many patients over 65 using cannabis without proper guidance from medical professionals.

Cannabis use is rising among older adults in the United States, including those over 65. However, researchers still have unanswered questions about how cannabis affects the body and brain due to its federal illegality. Many older adults use cannabis to ease chronic pain, insomnia, or anxiety. But there is no broad medical agreement that cannabis effectively treats these conditions.

Stanford Medicine specialists shared five important things older adults should know before using cannabis: 1. Today's Cannabis Is Much Stronger Than It Used To Be - Medical marijuana is legal in 40 states and the District of Columbia, while recreational cannabis is legal in 24 states and D.C. According to the National Survey on Drug Use and Health, 7% of adults over 65 reported recent cannabis use in 2023, compared with less than 5% in 2021. 2. Cannabis May Raise Risks for Heart Disease and Cognitive Problems - Several studies have linked regular cannabis use to cardiovascular disease. A Canadian study comparing emergency room visits before and after nationwide legalization found that cannabis poisoning cases among adults over 65 nearly tripled.
