That's really interesting. I dug a little more into it[0]. Apparently the underlying reasoning was that the Nazis associated smoking with "degenerates" and damage to "bodily purity." So when the research hit the US, people must have associated anti-smoking with those Nazi ideas. I wonder if tobacco companies latched onto this momentum to keep their public image healthy?
