I would love to see some studies on this because everything I've seen is either rats that were exposed to truly insane doses (10X more than a human would take) or among long term, heavy users (weekly).
I don't necessarily doubt that there's some level of brain damage going on, but the extent is poorly understood and likely over exaggerated.
