A member asked:

Please explain if it is the tobacco or what they add to it that gives you the cancer and how long would it take you to get cancer from smoking?

A doctor has provided 1 answer

It's the tobacco: The products of combustion include chemicals that wreck havoc on the genes. After 15 pack-years, your risk is much higher than other folks and doesn't return to baseline for a few decades. More important, you've become a slave to an addiction that now carries a serious stigma in the civilized world. I can't promise you cancer, but it will take your wind away both now and as you get older.
