Smoking Timeline

The moment you quit smoking, you set in motion an amazing healing process that starts with the feeling of fear and excitement over making such a positive change in your life. The healing process continues:

Thirty Minutes After Quitting…

Your blood pressure goes down. The nicotine in cigarettes stimulates the release of adrenaline , which raises your blood pressure. Chronic smoking then keeps your blood pressure high, which in essence creates persistent hypertension. Hypertension is a risk factor for strokes, heart attacks, heart failure, arterial aneurysm, and chronic renal failure.

Your pulse rate also decreases. Just like with blood pressure, the nicotine in cigarettes stimulates the release of adrenaline, raising your heart rate. An increased heart rate, especially over a period of time, can create a number of problems, increasingly inefficient pumping of blood by the heart and an imbalance in oxygen and carbon dioxide levels in the hemoglobin in the blood.

Eight Hours Later …

Two great things happen in your blood: the levels of poisonous carbon monoxide decrease because you’re no longer inhaling so much CO. This then allows your levels of oxygen in the blood to increase.

A Day Later …

Your chances of having a heart attack begin to go down—in just one day after having quit!

Two Days Later …

Your nerve endings begin to re-grow and your senses of smell and taste begin to improve.

Three Days Later …

You will be largely nicotine-free. Most of the nicotine metabolites in your body will have been passed through your urine. Although nicotine withdrawal will be peaking, your bronchial tubes will be relaxing, increasing your ability to breathe.

Two Weeks To Six Months Later…

Your circulation gets better, simple activities like walking get easier and you fatigue less quickly, the function of your lungs improves, you aren’t coughing nearly as much and your sinuses are less congested.

One Year Later…

You will have lowered your risk of coronary heart disease by half compared to smokers.

After Five Years …

You will have lowered your risk of stroke down to the same risk as people who have never smoked.

After Ten Years…

Your risk of lung cancer drops to as little as one-half that of people who continue to smoke. Furthermore, you will have significantly reduced your risk of developing cancers of the oral cavity, throat, esophagus, bladder, kidney, and pancreas.

After Fifteen Years…

Your risk of developing coronary heart disease will be no higher than that of people who have never smoked.

And most importantly, you will have lowered your risk of death—period—nearly to the level of people who have never smoked.
