Understandable. Nothing I hate more than trying to step outside for some fresh air and theres someone with a cig completely ruining that. Although weed may not have the harm that 2nd hand cig smoke does, having to smell it could be annoying. As for the genius trying the "someone taking a shit analogy", thats in a bathroom...not like someone just takes a shit in the park and its all good....
weed smoke doesn't bother me much but I could see how it could to someone else. I'd take it over people puffing cigs anyday tho, especially since most of them just flick the butts into the snow, which is bullshit.
