I read in a newspaper that even after just one spliff the stuff could damage you mentally. I tried the stuff once, but weirdly had no effect. Ill probably end up doing it alot more in the future tho.
But I do find all this mental health damaging quite frightening. Might put me off.

Patently false.
There is simply no evidence of permanent brain damage due to marijuana use. That according to gov't studies. You can't overdose from weed it's impossible. You don't take one more hit than normal and decide to go beat on people like alcohol. Is not phisically addictive etc.
Not that I'm saying everone should partake. I don't care either way. It's called freedom of choice.
