There are people using all sorts of substances irresponsibly. Whether its weed or alcohol, you will always find people who are polite or discreet about it and those who are out of control with it and don't care. That's why the stigma that surrounds "stoners" is completely biased and shouldn't be considered for any and all people who smoke weed. Many of us are very nice and down to earth people :) as for the smell, i have no rebuttal to that lol many people don't like the smell.
