I don't think it's fucked. Second hand smoking is harmful.

I'm one of them social smokers that smokes when they're drunk at a party and I'd be completely fine with the government banning smoking in public places and bars/restaurants. You're still free to smoke in your home.

Maybe it's a bit excessive to ban it from absolutely all open spaces like big parks and stuff but banning it anywhere a decent chunk of people passes every day is fine IMO.
