In 1981 the Federal Trade Commission of the United States issued a report to the American Congress that concluded health warning labels had little effect on public knowledge and attitudes about smoking.  As a result Congress enacted the Comprehensive Smoking Education Act of 1984, which required four specific health warnings on all cigarette packages and advertisements.

They are, as follows:

• SURGEON GENERAL'S WARNING: Smoking Causes Lung Cancer, Heart Disease, Emphysema, and May Complicate Pregnancy.

• SURGEON GENERAL'S WARNING: Quitting Smoking Now Greatly Reduces Serious Risk to Your Health.

• SURGEON GENERAL'S WARNING: Smoking by Pregnant Women May Result in Fetal Injury, Premature Birth, and Low Birth Weight.

• SURGEON GENERAL'S WARNING: Cigarette Smoke Contains Carbon Monoxide.

May I suggest a fifth:

• SURGEON GENERAL'S WARNING: There is No Risk-Free Level of Exposure to Secondhand Smoke.
