“Hitler remained closely involved with the crusade against tobacco to the very end. He banned smoking at his Austrian base, the Wolf’s Lair, and in the Fuhrerbunker in Berlin. In 1942, he voiced regret that he had ever allowed his troops a tobacco ration; a ration he would soon be forced to increase to boost morale when the war went from bad to worse. In 1943 he made it illegal for persons under the age of 18 to smoke in public places. A year later, with the Third Reich crumbling around him, Hitler personally ordered smoking to be banned on city trains and to protect female staff from second-hand smoke.”
“Hitler committed suicide in April 1945 and, after burning his body, SS troops lit cigarettes in the Fuhrerbunker for the first time. Within weeks, cigarettes became the unofficial currency of Germany, with a value of fifty US cents each. Hitler ultimately, if inadvertently, succeeded in reducing smoking in Germany but only by bringing the country to its knees.”
