your fucking spaced out pal, only a small majority of people smoke weed, mostly all of us trying it in our teens, there are a lot more people that drink alcohol, if this was not fact, then alcohol would be illegal and cannabis legal, also it is hard to make a good quality alcohol, but easy to grow a weed.
people go on about weed and medicinal properties, who gives a fucking toss about medicinal properties when all we want to do is get fucking pissed or stoned, its a bit like saying he broke his leg but the bottle of whiskey took the pain away, cannabis is NOT accepted in the real world, at least not by 9 out of 10 people.
if an astronaut even mentioned the word i think he would be grounded for life, even working on the railway warrants a urine sample for drugs. your as fucking mad as a brush.
