I can relate to that.
Without wanting to derail this thread any further, I have the opposite reaction. I have smoked a few cigars in my time — just for the humor of it — but I don't like them, and I hate the smell of them. The smell of cigarettes on the other hand has always felt comfortable to me — possibly because my dad, both of my grandfathers, most other male (and adult) family members, and most male friends of the family were all smokers, and so I grew up with that scent. It was as intrinsically linked to adult manhood as talking about automotive technology and playing cards on New Year's Eve.
Nevertheless, my parents have tried to discourage me from smoking when I was a teenager, namely by simply forbidding it. I started smoking during the final exams of my 9th-grade school year, and I had to keep my smoking a secret up until I was putting in my military service. When I was a teenager, my obsessive-compulsive mom would even go through the pockets of my coat almost every day while I was in my room doing my homework in order to look for tobacco crumbs, and if she found any — or worse, if she found any actual cigarettes, which did happen on a few occasions — then I was severely punished.
That all said, once we had moved to a different house — when I was 17 — I found that didn't like the smell of my dad's cigarettes anymore, and especially so when I was still busy eating while he lit up a cigarette after he had finished, but that's because from that point in time on, his cigarettes were hand-made, with the same kind of tobacco as for hand-rolling but with the tobacco inserted into the cigarette tubes by way of a little device. You know, you put the tobacco in the device, you attach a cigarette tube on one side, and then you pull the slide back and forth, and you've got a cigarette. He would always prepare a whole box like that in advance. It was cheaper than buying off-the-shelf cigarettes.
I'm not sure whether it was the particular flavor of tobacco that he was using or whether it was just that class of tobacco in and of itself. Tobacco for hand-rolling is commonly less finely cut and of a more moist variety than the kind that goes into prefabricated cigarettes. Not only do they smell differently, but they taste differently too.
Anyway...
