Myth: Marijuana Kills Brain Cells. Used over time, marijuana permanently alters brain structure and function, causing memory loss, cognitive impairment, personality deterioration, and reduced productivity.
Fact: None of the medical tests currently used to detect brain damage in humans have found harm from marijuana, even from long term high-dose use. An early study reported brain damage in rhesus monkeys after six months exposure to high concentrations of marijuana smoke. In a recent, more carefully conducted study, researchers found no evidence of brain abnormality in monkeys that were forced to inhale the equivalent of four to five marijuana cigarettes every day for a year. The claim that marijuana kills brain cells is based on a speculative report dating back a quarter of a century that has never been supported by any scientific study.

The reason they had brian cell loss is because they were suffocated you fucknut, they gave those 30 joints to them in 5 minutes. thats alot of smoke and not so much oxygen.

Again Read the stuides and stop using someone esle summary to prove your point read the studies and see mine.
you are so retarded that you let others do your thinking for you.
I actulyl read the studies with an open mind and if they would have been conclusive i would be the 1st to admit it. But they are not.
So it all comes down to Read the studies for yourself
