In 1941, tobacco smoking in trams was outlawed in sixty German cities. Smoking was also outlawed in bomb shelters; however, some shelters had separate rooms for smoking. Special care was taken to prevent women from smoking. The President of the Medical Association in Germany announced, "German women don't smoke". Pregnant women and women below the age of 25 and over the age of 55 were not given tobacco ration cards during World War II. Restrictions on selling tobacco products to women were imposed on the hospitality and food retailing industry. Anti-tobacco films aimed at women were publicly aired. Editorials discussing the issue of smoking and its effects were published in newspapers. Strict measures were taken in this regard and a district department of the National Socialist Factory Cell Organization (NSBO) announced that it would expel female members who smoked publicly. The next step in the anti-tobacco campaign came in July 1943, when public smoking for persons under the age of 18 was outlawed. In the next year, smoking in buses and city trains was made illegal, on the personal initiative of Hitler, who feared female ticket takers might be the victims of passive smoking.
