You don't even have to go that far back. I listen to old radio shows streamed online. They also play the commercials. The cigarette commercials from the 40s and 50s often mention health benefits of a particular brand over another. It's just weird.
I learned yesterday that my stepfather, who has been struggling w/lung cancer (lifelong Camels smoker), probably only has a few months left. The doctor told my mother about hospices, so I think that about seals it. For years I begged the two of them to stop smoking, but I was teased as being a health freak and afraid of a 'little smoke.'
Don't feel sorry for your stepfather. At least he can die a free man, who lived a long life and saw his grandchildren. Plenty of non smoking, salad eating vegetarians who can't say the same thing.
