Old mice given THC did better on memory tests
Old mice given THC, the active ingredient in marijuana, did better on learning and memory tests — though young mice did worse. It’s too early to say if this applies to humans, but the findings do shed some light into the possible effects of the drug.
Marijuana is known to have pain-relieving effects. People also think it might be bad for cognitive function, but there hasn’t been a lot of reliable research in this area.
