It's the genes. How well the body handles the different poisons we insist on shoveling in. I strongly suggest smokers and others look to family histories so as to get a read on the genes, what killed who. I'm adopted so, I can't do that.
Based on my 2 packs a day from age twelve until I added chewing tobacco a few years later (barns and flight lines) then pipes when I hit university I think I'm fairly safe at 72 from lung cancer. I had a precancer screening a few months ago and have very clear lungs. I bet my natural family line was fairly sturdy with regard to cancer. My adopted family is rife with cancers.
Now, heart disease? That's another subject entirely. I'm pretty certain my heavy smoking and chewing was a contributor to the failure of my immune system. Being a dedicated carnivore was a major contribution I sure.
Many doctors and others in the medical research field are sold on the idea that we all carry cancer around in our bodies. It's when we unbalance our immune system that cancers manifest themselves. So ... bad diet (However the government defines that at this moment.), tobacco, too much sun, the death of a loved one, car wreck, or any number of factors can cause the system to stress into failure.
Check your family histories, access the risk or flip a coin. Then, get a little risky and start with the nicotine if it pleases you. Maybe jack up the life insurance for the spouse and the children's education. Smoking is a selfish decision but, shouldn't hurt to consider your kids. I did, she'll collect a tidy little sum along with everything else she inherits.
