> before the 80s but during which smoking was still healthy

That's perhaps US-specific but it's certainly a strange view. Europe was issuing anti-tobacco advice and government health warnings in the fifties. The rise in lung cancers was noted pretty much immediately after the war. The US was late to that party, but even so was clear on the link between smoking and health in the sixties. We had anti-smoking and lessons on the effects of tobacco in UK schools in the 1960s, perhaps earlier. I sat through them in the 1970s - they weren't especially effective, but they were there.

That's despite all the free tobacco sent under the Marshall Plan to ensure Europe was good and addicted to Virginia leaf.

So what, the middle ages? Or the Victorian resurgence?
