Sure I've known some, and you can say the same about people who consume alcohol, but the truth is that the majority of smokers become lazy, and fry their brain. I have a friend who sleeps 18 hours a day now, because he smoked mj every day throughout his school years, (more than 4 years..) He is only a shell of what he was before he started smoking..
I agree totally that smoking mj slows you down, i know a number of smokers and there all the same, lazy, can't be bothered and un motivated to do anything accept sit on their behinds and smoke.
Alcoholics are just as bad, wake up, have a drink, maybe go to work with a sneeky flask of vodka and drink it all day, go home or to the pub after and drink themselves to sleep.
People with these habits and addictions have no lives, this is part of the cause of them turning to it in the first place. They have nothing else to do so they sit in the mj smoking circles moaning about how wrong the world is and the wars going on when they don't want to do nothing about it. As for the alcoholics they don't care because their off their trolleys anyway :)
