Marijuana can help prevent brain damage

world Updated: May 31, 2013 23:58 IST

Tel Aviv University researchers have found that extremely low doses of THC — the psychoactive component of marijuana — protects the brain from long-term cognitive damage in the wake of injury from hypoxia (lack of oxygen), seizures, or toxic drugs.

Brain damage can have consequences ranging from mild cognitive deficits to severe neurological damage. Previous studies focused on injecting high doses of THC within a very short time frame.
