Professor Andreas Zimmer, who led the study, told Deutsche Welle that learning and memory functions had improved dramatically in these animals, and they performed as if they were much younger.
When asked how they had tested a mouse’s memory, Professor Zimmer said that four weeks after they implanted tiny pumps under the animals’ skin which constantly released the drug, the results were quite staggering.
Professor Zimmer said that the kind of effect they had obtained was unique to cannabis, nothing else.
When asked if a young person could just walk away, smoke a joint and see his/her memory improve, he said that cannabis is a drug that has the opposite effect on young animals as opposed to old ones.
“It worsens memory in young mice. It also worsens memory in young humans. Don't smoke dope,” Professor Zimmer advised.
He added that smoking marijuana worsens cognitive function and memory, but the effect is temporary.
“If you stop smoking pot your memory functions will improve. But while you're smoking pot, you'll perform worse,” Zimmer noted.
