Well actually, I'm really uncomfortable simply being near anyone that's smoking weed. It has only happened once, a week ago.
I feel uncomfortable talking about it, or thinking that someone I know and love will start smoking it sometime.
It's because I am afraid of the thought of becoming addicted. Which is why I don't even try smoking a cigarette.
But that's good, I guess.
So no, I would not like it to become legal (I live in Sweden, shouldn't have to worry), because I would literally be uncomfortable all the time outside.
EDIT: And well I am used to cigarettes since it's very common these days, and my mom smoked it all my life up until a year ago.
