What was behind the mysterious increase in lung cancer deaths at the turn of the 20th century? The first of a three-parter investigating the cigarette-smoking link and causality, this episode looks at that early debate, which largely focused on environmental pollution. Along the way, we’re going to talk about toxic vapors -- and not Miasma theory, but the actual literal Great Smog of London in 1952 that killed over 10,000 people -- as well as the birth of the case-control study, Nazi attempts at tobacco control programs, and the rather prosaic beginnings of a debate that rages to this day. Plus a new #AdamAnswers about the medical cause of Game of Thrones greyscale featuring Dr. Jules Lipoff!   Sources: Bell, M. L., Davis, D. L. & Fletcher, T.
