If I was to quit smoking I would have to burn everything I own to include my shop which my father smoked in.I wouldn’t be able to stand the smell.
I quit about 15 years ago but I don’t have any issues with smokers. I keep ashtrays in my house. I don’t drink anymore either but I’ll pick up beer on my way to a party but I’ll drink Gatorade or soda.
You’re right, smoking definitely inhibits olfactory sensitivity.
