I've always been on the other side of this, so I don't see it in quite the same way. I don't know if I'll get my ass kicked for this but.... I've always felt that people choose to smoke. This is as conscious a decision as my decision to not smoke. And my decision doesn't harm your health. However, yours harms mine, and thus I should not be subjected to the consequences of someone else's choice.

As for the air purifier... the second-hand smoke is still harmful, unless the purifier is attached to the end of your cigarrette.

Sorry.

You see these shackles
Baby I’m your slave
I’ll let you whip me if I misbehave

Tie me to the bedpost

I like it rough
cause I'd rather feel pain than nothing at all
