Simply put this is how I look at it. It should be the owner of the property's decision more than anything else. If a business, like a bar, flower store, or whatever wants to allow it then everyone else that doesn't want to be around that shouldn't go there. More and more and this government lives, talking about the U.S. bc I live there, seem to think it should be the governments decision to get rid of things for us that we are up in the air about. A lot of people are back in forth on this. I think that shouldn't matter. It isn't the laws decision to tell us what the rules are. As a government of the people we should make the rules. It shouldn't be their decision what we do that effect our bodies. And yes I'm aware of the argument of second hand smoke. Anything that is public transport, government run, and things like that I understand a ban there, but past that the decision should be based on who owns the property and if you don't like it don't give them your business.
