That is not medically accurate. There are some low-quality observational studies which show a weak correlation between cancer rates and subject-reported consumption of certain types of preserved meats. Those studies were mostly junk science with multiple uncontrolled variables.
It's specifically the nicotine in tobacco that is somewhat addictive. But nicotine isn't generally considered to be a carcinogen by itself.
Your argument reminded me of that scene from "Thank you for smoking"
Nick Naylor: Oh, this from a Senator who calls Vermont home.
Senator Lothridge: I don't follow you, Mr. Naylor.
Nick Naylor: Well, the real demonstrated #1 killer in America is cholesterol. And here comes Senator Finistirre whose fine state is, I regret to say, clogging the nation's arteries with Vermont Cheddar Cheese. If we want to talk numbers, how about the millions of people dying of heart attacks? Perhaps Vermont Cheddar should come with a skull and crossbones.
Senator Finistirre: That is lu --. The great state of Vermont will not apologize for its cheese!
Senator Lothridge: Mr. Naylor, we are here to discuss cigarettes -- not planes, not cars -- cigarettes. Now as we discussed earlier these warning labels are not for those who know but rather for those who don't know. What about the children?
Nick Naylor: Gentlemen, it's called education. It doesn't come off the side of a cigarette carton. it comes from our teachers, and more importantly our parents. It is the job of every parent to warn their children of all the dangers of the world, including cigarettes, so that one day when they get older they can choose for themselves. I look at my son who, was kind enough to come with me today, and I can't help but think that I am responsible for his growth and his development. And I'm proud of that.
