Access to medical marijuana dispensaries was associated with significantly improved self-reported mental health among older adults in New York, according to a study published in Economics Letters. Researchers found that having a medical marijuana dispensary within a 30-minute drive reduced the likelihood that adults aged 65 and older reported experiencing any poor mental health days during the previous month by 3.77 percentage points. The study examined geographic access to medical marijuana rather than whether individual respondents personally used marijuana. In addition to the improvement identified among older adults, researchers found no evidence that medical marijuana dispensary availability negatively affected the likelihood of reporting poor mental health days among the overall adult population. The findings indicate that the availability of medical marijuana “has positive mental health impacts for older populations,” according to the study’s conclusion.
