Older adults with a history of cannabis use exhibit superior cognitive performance and slower age-related declines in executive function, according to data published in the journal Age and Ageing. Israeli researchers assessed cognitive performance in a cohort of more than 67,000 adults (mean age: 67 years old). Compared to non-users, participants with a history of cannabis use “performed better across all cognitive domains: attention, executive function, processing speed, visual and working memory. … Additionally, past use was associated with a slower decline in executive function.” Positive associations were strongest for former users, while outcomes were less consistent among current cannabis consumers.
