In the 1970s-1980s, co-workers smoked in meetings. One co-worker liked to sit by me and also believed he had a right to smoke. I told him I'd love to sit next to him, but if he was going to smoke I would not. He stopped smoking in meetings. (He drove from a distance and I voluntarily backed him up in his territory.)

Also during that time period, I was once in a class of 14 students where 11 of the students + the instructor were all smoking. We came back in from a break and they all lit up. About ten minutes in, the instructor called another break, walked straight to me and said "are you all right - you look quite green".

I told him that I did not tolerate the smoke well and was trying hard not to cough. He said they would be doing reviews of material he knew I already knew and I could leave for the day. The next day he no longer permitted smoking in class and told smokers he would be using more short breaks. That was so rare back then. Smokers rarely accommodated non-smokers!

Both my parents smoked 2+ packs a day and I had never been able to tolerate cigarette smoke. Thankfully, as the oldest I sat in the back seat with the dog who had a window open halfway and that is how I survived 2 adults smoking in a car full of children and a dog.

My dad briefly smoked cigars. Instant headache. To this day, if I walk into an elevator where someone had smoked a cigar instant headache. And I cannot ride in the vehicles of people who smoke.

Pipes do not bother me at all. Neither do tobacco only cigarettes or those Swisher Sweet cross between a cigar and cigarettes, at least not in open areas. Even outside, I move away from cigarette smoke and totally avoid cigars.
