Summary: Recreational cannabis use may be associated with a significant decrease in the odds of experiencing subjective cognitive decline (SCD) in adults over 45. Analyzing data from the CDC’s 2021 Behavioral Risk Factor Surveillance System, researchers found that recreational users had 96% lower odds of reporting SCD compared to non-users.
This intriguing finding suggests potential protective effects of cannabis on cognition, although the study’s authors emphasize the need for longitudinal research to understand the long-term impacts. Despite its limitations, the study contributes to the evolving conversation around cannabis use and cognitive health, highlighting the importance of differentiating between medical and recreational use in research.
Key Facts:
A new study by Upstate Medical University researchers shows that recreational cannabis use may offer protection against cognitive decline.
The study, done by Master of Public Health (MPH) student Zhi Chen and Professor Roger Wong, Ph.D., MPH, MSW, analyzed a large data set from the CDC and found that compared to non-users, non-medical cannabis use, such as for recreational purposes, was significantly associated with 96 percent decreased odds of subjective cognitive decline (SCD).
Medical and dual (medical and non-medical) use were also associated with decreased odds of SCD, although not significant. Cannabis consumption frequency and method were also not significantly associated with SCD.
