Damage from smoking is within 30 minutes of first cigarette

A study has been conducted that shows damage starts almost immediately from smoking.
'Professor Stephen Hecht, from the University of Minnesota, said: "This study is unique, it is the first to investigate human metabolism of a PAH specifically delivered by inhalation in cigarette smoke, without interference by other sources of exposure such as air pollution or the diet.'
So the message is: don't start and if you have, quit as soon as possible!!!!!!
