Cigarette smoking, more common in the United States of the 1960s than it is now, is featured throughout the series; many characters can be seen smoking several times over the course of an episode. In the pilot, representatives of Lucky Strike cigarettes come to Sterling Cooper looking for a new advertising campaign in the wake of a Reader's Digest report that smoking will lead to illnesses, including lung cancer.  Talk of smoking being harmful to health and physical appearance is usually dismissed or ignored. In the fourth season, after Lucky Strike fires Sterling Cooper Draper Pryce as its ad agency, Draper writes an advertisement in The New York Times titled "Why I'm Quitting Tobacco", which announces SCDP's refusal to take tobacco accounts. The finale finds the agency in talks with the American Cancer Society. In the series' penultimate episode, Betty Draper is diagnosed with terminal lung cancer, after having been depicted as a heavy smoker throughout the series. The actors smoke herbal cigarettes, not tobacco cigarettes; Matthew Weiner said in an interview with The New York Times that the reason is that "you don't want actors smoking real cigarettes. They get agitated and nervous. I've been on sets where people throw up, they've smoked so much".
