"Cigarette smoking is the single most preventable cause of premature death in the United States. Each year, more than 400,000 Americans die from cigarette smoking. In fact, one in every five deaths in the United States is smoking related."

Well, that's amazing given that 25% of people in America smoke. So apparently if you die and you're a smoker, there's near 100% chance smoking is what killed you. Not a heart attack you would've had anyway, etc.

There were 450,000 heart attacks in 2004. 20% were "due to smoking". That happens to coincide with how many people smoke in this country. Are you still going to suggest this is the delta? Because mathematically it doesn't add up.
