I was in college when the bars in my college town went smoke free. It was noticeable how all of a sudden I didn't feel like my night needed to end with a shower just because I went out and didn't want to lay in bed smelling like an ashtray. So yeah, well before the hug.

And the things it does to your skin. You can tell a smoker from across the room by looking at their face.

Smoking was a signal between men and women that we were on the same page. It was also a way for women to initiate a conversation with a man without coming on too strong.

It doesn't take a kiss or hug, I have a visceral reaction to just talking to or walking by someone who stinks of cigarette smoke, it's disgusting to me. I'll still assert that all people are innately deserving of compassion and respect, but it takes effort and a choice when I smell that.

As a father, an uncle, and a dog owner who has changed a lot of diapers and cleaned up a lot of poop (at ~10 years x 365 days x 1-10 events/day x ~1 lbs/event, probably a literal ton of shit) and been numbed to the smell, I'd literally prefer to smell feces in your adult Depends than cigarette smoke on your breath. It's not "hot" at all, completely the opposite.
