First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how cannabis affects memory in people who use it regularly. 121 participants inhaled either a low or high dose of cannabis, or a placebo, and then took a series of memory tests. The goal was to see if cannabis makes it harder to remember things like words, pictures, and tasks. The results help us understand the short-term memory effects of cannabis.
