Not even alcohol (one of the "dirtiest" drugs as far as physiological effects go) kills brain cells. I wish this myth would die. The issue is in the way they affect your dopaminic and serotonergic regulation and how this can fuck up your brain chemistry, not that they're literally killing off your brain cells.

> My concern with modern (incredibly strong) Cannabis/THC is that some regular users seem to struggle with withdrawal if they don't smoke their bowls regularly, run short on weed etc.

That said, this is a very legitimate concern I have as well. It doesn't help that a lot of stoners seem like they're in denial over the fact that they gasp have a dependence on this substance like an alcoholic or smoker does.
