    Here’s what the American Lung Assocation says on their web site:
    When smokers quit, within twenty minutes of smoking that last cigarette the body begins a series of changes.
    At 20 minutes after quitting:
    blood pressure decreases
    pulse rate drops
    body temperature of hands and feet increases
    At 8 hours:
    carbon monoxide level in blood drops to normal
    oxygen level in blood increases to normal
    At 24 hours:
    chance of a heart attack decreases
    At 48 hours:
    nerve endings start regrowing
    ability to smell and taste is enhanced
    The first year after quitting:
    At 2 weeks to 3 months:
    circulation improves
    walking becomes easier
    lung function increases
    1 to 9 months:
    coughing, sinus congestion, fatigue, shortness of breath decreases
    1 year:
    excess risk of coronary heart disease is decreased to half that of a smoker
    Long-term Benefits of Quitting
    At 5 years:
    from 5 to 15 years after quitting, stroke risk is reduced to that of people who have never smoked.
    At 10 years:
    risk of lung cancer drops to as little as one-half that of continuing smokers
    risk of cancer of the mouth, throat, esophagus, bladder, kidney, and pancreas decreases
    risk of ulcer decreases
    At 15 years:
    risk of coronary heart disease is now similar to that of people who have never smoked
    risk of death returns to nearly the level of people who have never smoked

    uh…no. sorry, good theory/myth, but no it cannot clean itself…its not a kidney…and it cannot grow parts back like a liver…..its very sensitive to contaminants and such…..ALTHOUGH a climate change can help the damage that has been done, heal over, which would make you feel like its the same as it was, but it will never be the exact same.

    No, it’s not. No matter how long you smoke,
    5 weeks, 5 months, 5 years or 25 years, the
    tar and nicotine remain in your system.
    Of course, the sooner you quit, the less likely
    you’ll suffer any serious illness from it–such
    as a heart attack or cancer.

    Yes totally true. There can be some fiberous scar tissue, but very little after 5 yrs.

    Regardless of how long you have smoked, if you quit, your lungs will begin to get healthier. However, the lungs of a smoker or ex-smoker will never be as healthy as the lungs of a non-smoker (who hasn’t been subjected to secondhand smoke).

    I heard that too. It probably is true as far as appearances go, but cellular changes deep within the lungs can still come about because you smoked. Herb Caen, a famous San Francisco newspaper editorial writer died of lung cancer and he had quit smoking for 20 years before he died. However, your chances of a longer, healthier life begin the day you quit smoking and improve every day after that. Just drive carefully, that’s your biggest risk in life.

    No, it’s not true.
