The regulations don’t apply to private spaces and only when in sight of the protected locality in the centre of the red circles.
And there are other regulations, so many other regulations…
But hey, I can at least legally consume in the privacy of my own home now, so I got that going for me, which is nice.
No one is gonna catch you if you eat some cake in public. So while it technically applies to edibles too, in practice it doesn’t.
And yeah, cities have a lot of people and a lot of children, no shit.
Drop that cake and nobody needs to get hurt, perp!
Well it does, if you are stupid enough to be open about it towards a cop. So good to know anyway.
And like I said, I’d even be fine with that if it was equally applied to anything you smoke. But the ban doesn’t include tobacco, doesn’t even refer to smoking at all in fact, and in its current form essentially bans public consumption for entire neighbourhoods. So I would posit there is some room for improvement.
