Regular low doses of THC dramatically boosted memory and learning in older mice, say scientists, who plan a clinical trial in humans later this year
Researchers have come up with an unusual proposal to slow, or even reverse, the cognitive decline that comes with old age: small, daily doses of cannabis extract.
The idea emerged from tests on mice which found that regular, low doses of tetrahydrocannabinol (THC) – the main psychoactive ingredient in cannabis – impaired memory and learning in young animals, but boosted the performance of old ones.
