  2. Item 1: There is really no risk at all for the first two years
  3. Item 2: Every single cigarette smoked causes a little bit of harm
  4. Item 3: Although smoking may eventually harm this person’s health, the very next single cigarette he or she smokes will probably not cause any harm
  5. Item 4: Harmful effects of smoking rarely occur until a person has smoked steadily for many years
  6. Item 5: Smoking at the daily rate of one package of cigarettes each day will eventually harm this person’s health
