Smoking - an evidence based analysis of the national data

A study from the Journal of the National Cancer Institute puts some perspective on smoking.  I had been discussing this with patients and my numbers are pretty accurate with what this article concludes.  CIGARETTES ROB 5 TO 10 YEARS FROM THE LIFE OF SMOKERS.  Thats the conclusion. Its an average, not all smokers will die 5 - 10 years sooner than non-smokers but on the whole, smokers die that much sooner and for every smoker that lives to the ripe old age of 90 (about 10 years longer than normal) there is a smoker that dies at 50 (twenty years sooner - 10 to balance the 90 year old and 10 because the average is lower!).  So maybe some smokers live a long life but most on average die 5 to 10 years sooner.  What would you give to live 5 or 10 years longer if you found out you were dying.  Would you give up smoking then?
