Summary:

- A new study published in the journal Addiction found that marijuana use does not have significant harmful effects on age-related cognitive decline.
- The study analyzed data from over 20,000 participants and found that while cannabis use was associated with poorer cognitive performance, it did not exacerbate the typical cognitive decline seen with aging.
- The researchers suggest that the cognitive effects of marijuana may be more acute in the short-term, but do not appear to have long-term detrimental impacts on brain function as people get older.
