The first modern, nationwide tobacco ban was imposed by the Nazi Party in every German university, post office, military hospital, and Nazi Party office, under the auspices of Karl Astel's Institute for Tobacco Hazards Research, created in 1941 under orders from Adolf Hitler. Major anti-tobacco campaigns were widely broadcast by the Nazis until the demise of the regime in 1945.

Reductio ad Hitlerum, also argumentum ad Hitlerum, (dog Latin for "reduction to Hitler" or "argument to Hitler," respectively) is an ad hominem or ad misericordiam argument, and is an informal fallacy. It is a fallacy of irrelevance where a conclusion is suggested based solely on something or someone's origin rather than its current meaning or context. This overlooks any difference to be found in the present situation, typically transferring the positive or negative esteem from the earlier context. Hence this fallacy fails to examine the claim on its merit.
Its name is a pun on reductio ad absurdum, and was coined by an academic ethicist, Leo Strauss, in 1953. Engaging in this fallacy is sometimes known as playing the Nazi card, by analogy to playing the race card.
The fallacy claims that a policy leads to—or is the same as—one advocated or implemented by Adolf Hitler or the Third Reich, and so "proves" that the original policy is undesirable. For example: "Hitler was a vegetarian, so vegetarianism is wrong." The tactic is often used to derail arguments, because such comparisons tend to distract and anger.
