(21,046 posts)They said that cigarettes caused cancer sometime in the early 1960s. Both my parents smoked because it was common in their generation (people who were young adults during World War II). They both quit in the 1960s, but not before the damage was done to my lungs by second-hand smoke. I have scar tissue in my lungs that can be seen on an x-ray. It looks like little specks of dandruff on the lining of the tubules. I have never smoked tobacco myself. Not once.
Although I am glad that they quit and thus lived a lot longer than they would have otherwise.
