Researchers reported that those with a history of cannabis use “demonstrated significantly better cognitive performance.” Cannabis use “was not associated with increased risk of dementia” and researchers found “no supporting evidence of a causal link with [longitudinal] cognitive decline in later life.”
“This study adds to a growing body of evidence that cannabis use may be associated with greater brain volume and cognitive performance in aging adults.”
“The results of this study indicate that cannabis may be a relatively safe and effective treatment for chronic pain, sleep disturbances, and other conditions associated with aging, leading to subsequent reductions in prescription drug use and healthcare costs, as well as significant improvements in quality of life.”
