Key Points:
- A study published in BMJ Mental Health found that cannabis use by older adults is not linked to accelerated cognitive decline or increased dementia risk, based on data from large cohorts in the UK and US.
- Researchers observed that lifetime cannabis users demonstrated significantly better cognitive performance across memory, intelligence, and problem-solving domains compared to non-users.
- The study aligns with previous research from Israel, Denmark, and the US suggesting cannabis use may have neuroprotective effects and be associated with slower cognitive decline in aging populations.
- NORML’s Deputy Director Paul Armentano highlighted that these findings challenge longstanding negative stereotypes about cannabis and cognitive health that often go unchallenged in mainstream media.
