Late Gen X, practically Millennial here.

My parents expressly forbade me from smoking despite being heavy smokers themselves. They also got that same forbidding from their parents, but I guess it didn't stick with them.

As such, I'm not sure whether that had any influence, or whether it was a natural aversion to the stink and filth of it but I've never smoked. Cost would have also been a big factor that prevented me from getting into it. I never had any money as a kid, and also had no smoker friends, let alone generous smoker friends, so getting a hold of anything to smoke was pretty much impossible.

Stealing from my parents might have been an option, I suppose, but I would not have wanted to face their wrath had I done that.

Alcohol and I do not get along. Too many bad experiences have come about through the combination, and it took far too long for me to learn lessons from it.

Even if I was not on medication that came with the heavy suggestion to avoid alcohol, I would not drink.
