“Germany had the world’s strongest antismoking movement in the 1930s and early 1940s, supported by Nazi medical and military leaders worried that tobacco might prove a hazard to the race. Many Nazi leaders were vocal opponents of smoking. Anti-tobacco activists pointed out that whereas Churchill, Stalin, and Roosevelt were all fond of tobacco, the three major fascist leaders of Europe — Hitler, Mussolini, and Franco — were all non-smokers.”
