Bars in Colorado are doing just fine with the smoking ban.
They all have smoking patios.
Ah....yes that is how restaurants and bars adapted here in Toronto once the smoking ban came in but guess what the patios eventually were made smoke free as well along with public parks. How enforceable the parks rule is I don’t know but it will be interesting to see how things shake out. The upcoming legalization of mj will produce lots of new adaptations. The libs initially proposed that those using med mj could smoke anywhere they wanted regardless of smoking bans but they got a lot of pushback on that and retreated that typically insane idea.
