Context and question: Eisenhower began smoking cigarettes at West Point, often two or three packs a day. Eisenhower stated that he "gave [himself] an order" to stop cold turkey in March 1949 while at Columbia. He was probably the first president to release information about his health and medical records while in office. On September 24, 1955, while vacationing in Colorado, he had a serious heart attack that required six weeks' hospitalization, during which time Nixon, Dulles, and Sherman Adams assumed administrative duties and provided communication with the President. He was treated by Dr. Paul Dudley White, a cardiologist with a national reputation, who regularly informed the press of the President's progress. Instead of eliminating him as a candidate for a second term as President, his physician recommended a second term as essential to his recovery.

two or three packs
