I'm just wondering where someone would go by choice to sit down next to someone smoking weed? Can't smoke cigarettes in any restaurant, bar, park here and several cities (including Corvallis) have made it pretty much illegal to smoke anywhere other than private property.
I've gone to houses where people were smoking weed but have yet in over three years to experience anyone smoking weed outside in a public setting, but I don't go to Burning Man, etc. either.
