Whether to smoke or assemble, they'll have to make a choice. Go naked or assemble, be a public nuisance or assemble, .... Life is full of choices.
If a smoker wants to smoke, my answer to him is, "Certainly,BUT SMOKE THE DAMN WEED OUTSIDE. I DON'T NEED CANCER FROM YOUR BUTT."
I own the business and I invite you in, why should I not be able to enjoy the company of folks that choose to smoke if I so desire.
Additionally, these smoking bans FORCE the owner of the PRIVATE property to have to exit his PRIVATE property if he happens to be a tobacco smoker.
if you don't like being around smokers, find an establishment that doesn't permit it, or talk to the owner of the ones that do.........keep the government out of it. It may be something you enjoy next.
