I remember going to restaurants as a kid and being asked if we wanted the smoking or non-smoking section. It seems kind of surreal these days that this was ever a thing. I'm probably the last generation to remember indoor smoking.

Back many many moons ago in the year 2008 I traveled to the great city Vancouver to see a friend. They took me to a venue to see a band and cigarette smoking wasn't allowed.

But you bet your fucking ass there was plenty of people smoking weed. Which seems to be just fine...breathing in second hand smoke...which is the main reason these tabacco restrictions are in place.

EDIT

I don't care if you smoke weed, only it has the same second hand smoke issue tabacco does and should follow the same rule.

In the US, cigarette smoking had already peaked and begun to decline before smoking bans. The bans almost certainly accelerated the decline, though.

Man, my freshman year of college, in California of all places, we had cigarette vending machines in our freshman dorm. The only smoking policy in your dorm room was that your roommate had to be cool with it. Zero designated non-smoking rooms. There was a smoking section inside the cafeteria. You couldn't smoke during class, but the professors could smoke in their offices and we had a coffee bar in the building that was one huge cloud.

How things have changed, eh?
