Surgeon general: Even one puff can be too much

Washington, D.C. – Just one puff on that cigarette could be the
one that causes your heart attack.
The surgeon general's 30th annual report on smoking and health
says tobacco smoke begins poisoning immediately, as more than 7000
chemicals in each puff rapidly spread through the body to cause
damage to nearly every organ.
The report warns that even a bit of social smoking -- or
inhaling someone else's secondhand smoke -- could be enough to
block the arteries and trigger a heart attack.
Surgeon General and Alabama native Regina Benjamin says kicking the habit lets the body start healing immediately. She adds "It's never too late to
quit -- but the sooner you quit, the better."
