Didn't read trough the whole thread but I will post my mind anyway.
Marijuana, Cannabis, etc. are the same thing as alcohol, cigars, cigarettes......drugs. I' not planning , not even thinking about drinking or smoking in any point in my life because it simply isn't good. It doesn't make you smarter, faster, stronger, nothing.. it just makes you weaker in any way possible , it's poison in every shape and size to which you will get addicted ,if your mind is not strong enough, thus making you spent more money on more poison which will take your health at an even lower level.
So for me it's a plain and definitive never to marijuana or any other form of body poison. Their is simply no point in doing it.
