I was born with a deviated septum, so I can’t smell much of anything, but cigarette is one thing I can smell… And I can confirm everything in your post.

My dad used to smoke. A lot. I once had to borrow his car for a week or so and couldn’t even drive it without flooding it with febreze and opening all the windows.

I used to have a co-worker who smoked so much that I (and others with more sensitive schnozzes) could tell if he’d been in a room in the past hour or more.

Even if you don’t care about your own health, you shouldn’t smoke for the sake of those around you.
