According to the Surgeon General's report:

But that wasn't the intent of Congress, or of the anti-smoking groups which supported the Family Smoking Prevention and Tobacco Control Act. The intent was to gain a political victory by making it look like they were doing something to protect the public's health, when in truth, they weren't actually doing anything to make cigarettes safer. If anything, they were putting obstacles in the way of transforming the tobacco market into one that is safer.
