I quite a pack a day habit 12 years ago and one of the first things I noticed when my sense of taste and smell returned was how aweful smokers smelled when they’d walk into a building after a cigarette. I had thought the smell was off me within maybe 10 minutes but I found out quick that the smell never really goes away. Feels like a previous life thinking I smoked because I can’t see myself ever smoking even a single cig for the rest of my life because it’s so revolting to me now. Oddly enough, however, sometimes I’ll see someone light up a fresh cig in a movie or something and I’ll get this strong 2-3 second craving for a smoke. It’s so strange how even over 12 years since my last one, I still get these strange urges for a cig by seeing someone of TV light one up.
