New research published in the journal JAMA Internal Medicine reveals a concerning trend: a growing number of seniors are using marijuana, with 7% of those over 65 now being current users. This represents a near 50% increase from 2021 to 2023, raising alarms about the health risks associated with cannabis use among the elderly.
Dr. Marc Siegel, a practicing internist, highlights the dangers of this trend, noting that marijuana use among seniors is linked to significant health risks. The active ingredient in marijuana, THC, can damage the lining of blood vessels, similar to the effects of cigarette smoke, leading to hypertension, heart attacks, and strokes. Additionally, studies show that THC can cause IQ decline, poorer cognitive function, and exacerbate existing mental health issues such as anxiety and psychosis in elderly individuals.
Combining marijuana with alcohol is particularly hazardous, especially for elderly drivers who may already have impaired driving abilities. Research indicates that car crashes involving both substances have increased dramatically over the past two decades. Moreover, the potency of modern cannabis products is far higher than in previous decades, with THC concentrations reaching 30-50%, which can have more severe and prolonged effects on seniors who metabolize chemicals more slowly.
Dr. Siegel also warns against the misconception that cannabis is a safe solution for chronic pain or sleep problems. While some believe it has medical benefits, evidence is limited, and the potential side effects often outweigh any minimal benefits. The growing acceptance of medical marijuana has led to broader recreational use, with cannabis now fully legal in 24 states. However, the risks for seniors, including the potential for addiction and cognitive decline, are significant. Dr. Siegel stresses that it is crucial to reconsider the role of cannabis in the lives of older adults to protect their health and quality of life.
