What Happens When You Quit Smoking?

When you put out the cancer sticks, nothing but good happens!

No doubt about it: Smoking is bad. But what happens when you quit? It all gets better (some of it almost immediately!), trust us.

  • Your blood pressure and heart rate drop to normal 20 minutes after your last cigarette.
  • Two hours after you quit circulation to your fingers and toes improves. (Note: Nicotine withdrawal symptoms usually start about two hours after your last cigarette. Symptoms include cravings, anxiety, trouble sleeping and increased appetite. These usually ease after two weeks.)
  • Eight to 12 hours after your last puff, the level of carbon monoxide in your bloodstream drops to normal and the oxygen level rises to normal.
  • Your chances of a heart attack decrease—after just 24 hours. The heart attack rate for smokers is 70 percent higher than for non-smokers.
  • You start to smell and taste things more vividly again after 48 hours without a cigarette.
  • Two to three weeks after you quit, you’ll be able to exercise without feeling winded.
  • At the three-month mark, your circulation improves and your lung function increases up to 30 percent.
  • You have increased energy. Coughing and shortness of breath are greatly reduced. You are less likely to contract lung infections. This happens by the nine-month mark.
  • A year after you quit smoking, your risk of coronary heart disease is half that of a smoker’s.
  • Five years after you dump this bad habit, your risk of esophageal, lung, mouth and throat cancers drops dramatically. Your risk of having a stroke is the same as your other nonsmoking pals.
  • Ten years after smoking, your lung cancer death rate is about half that of a smoker’s. This is great news; smoking accounts for 90 percent of lung cancer deaths worldwide.
  • Fifteen years after you put out the butts, your risk of heart disease is the same as someone who doesn’t smoke.
