A new scientific study on the effects of cannabis on mice of varying ages showed that mature and older mice exhibited vastly improved memory and cognitive abilities when given a daily dose of cannabis extract. The change was so drastic, the older mice performed as well as drug-free young mice in memory tests.
Unexpectedly, younger mice who were given the same dose, performed worse on the same tests than the older mice who were given cannabis.
“These results reveal a profound, long-lasting improvement of cognitive performance resulting from a low dose of THC treatment in mature and old animals,” the scientists write. The boost in brain function was linked to an apparent restoration of gene expression in the brain to more youthful levels.
