The initiative says that smoking pot won't be allowed in a public place, a "marijuana establishment", or in a moving vehicle. The definition of public place is pretty expansive, which is any place where the public is allowed to be or invited. I suppose they could do something like Utah liquor laws and call a place a "private club". It certainly doesn't sound like a casino could open a pot room onsite and allow pot smoking there.
Yet one can smoke in the casinos that are quite public. Where there's a will, there's a loophole.
I heard that several are running out of pot. And the strange way they have it set up is that licensed liquor vendors are the ones that are supposed to be authorized to be wholesalers, but none have an active license yet.
As far as I can tell, only age-restricted casino floors and bars are exceptions from the Nevada's indoor smoking law. Before the law, I found it odd when I was in a restaurant in Reno, and I was asked if I wanted to be in the smoking or no smoking section. I hadn't been asked that question in California for a long time. I also found it odd that Nevada even enacted a ban on smoking, given the biggest indstries are all vices.
However, pot isn't considered the same as tobacco or vaping. Question 2 made it clear that smoking pot wouldn't be legally allowed in any public place. Now illegal is another matter. I've been to plenty of places where the smell was unmistakable, but nobody seemed to care.
Not sure how that would work since the actual city of Las Vegas is pretty small and doesn't cover most of the area that most people think of as Las Vegas. I thought that a lot of the laws that apply to the Strip and other areas are enacted by Clark County or the state since most of the area is unincorporated.UPDATE: Las Vegas has now passed a venue ordinance allowing for Pot venues.
