New Studies Suggest Cannabis Use in Seniors May Enhance Cognition and Reduce Alcohol Consumption

Two recent studies are challenging long-held perceptions about cannabis use among seniors, suggesting potential cognitive benefits and reduced alcohol consumption. The first study, involving over 67,000 adults with a mean age of 67, found that those with a history of cannabis use performed better on several cognitive tests compared to non-users. The second study, conducted in Oregon, revealed that proximity to licensed cannabis retailers is associated with lower rates of heavy alcohol use, particularly among seniors and young adults

The cognitive study, highlighted by NORML, utilized data from the UK Biobank to assess various cognitive domains, including attention, executive function, and memory. Interestingly, former cannabis users displayed the most significant cognitive advantages, showing better scores and slower decline in executive function over time. Current users also exhibited benefits, though these were primarily in working memory, suggesting that cannabis use does not necessarily correlate with cognitive deficits in older adults

Researchers emphasized the importance of evidence-based discussions about cannabis use, noting that previous assumptions about cognitive harm may not hold true. The findings align with other research indicating minimal long-term cognitive damage from moderate cannabis use, especially when initiated after adolescence. This growing body of evidence calls for a reevaluation of public health messaging and clinical advice regarding cannabis use in older populations

The second study, conducted by Oregon State University, focused on the relationship between legal cannabis access and alcohol consumption patterns from 2014 to 2022. It found that adults living closer to cannabis retailers were less likely to engage in heavy drinking. This trend was most pronounced among young adults aged 21-24 and seniors over 65, suggesting a potential substitution effect where cannabis replaces alcohol in certain demographics

Importantly, the Oregon study found no increase in cannabis use among minors, reinforcing the effectiveness of age-verification measures at licensed retailers. The researchers suggest that the substitution of cannabis for alcohol could have positive public health implications, given the well-documented risks associated with heavy drinking. Similar trends have been observed in other states with legal cannabis, where reduced alcohol and opioid mortality rates have been reported

While these studies provide valuable insights, they are observational and do not establish causation. Factors such as lifetime cannabis exposure, frequency, and individual health conditions can influence outcomes. Moreover, the correlation between cannabis retailer access and reduced alcohol use may be influenced by broader social trends and policy changes. Nonetheless, the data highlight a shift in substance use patterns that warrants further investigation and consideration in public health discussions

For older adults, these findings are particularly relevant as they navigate health decisions and conversations with healthcare providers. The studies challenge the stigma surrounding cannabis use in seniors and underscore the need for nuanced, evidence-based policy and health advice. As the senior population continues to grow within the legal cannabis market, understanding the real-world impacts of cannabis use becomes increasingly important for informed decision-making
