Observational analysis reveals similar cognitive performance in older adults, with cannabis risk factors indicating potential memory decline.
Key Points
Participants with recent cannabis use showed comparable cognitive performance across neuropsychological domains, and those with no cannabis use performed similarly.
Approximately 11% reported cannabis use in the past six months, with most using it two to four times monthly.
Using propensity score matching, causal techniques evaluated cannabis use effects on cognitive functioning among older adults.
Findings suggest that while low-frequency cannabis use is tolerated, higher cannabis-related problems may impair memory performance.
