Healing from the damage done from smoking cigarettes is not different. This article explains what happens to your body in the first hours, days, weeks and years after a person stops smoking. The benefits are almost instant; as soon as a person stops smoking their body begins to recover in the following ways:

After 1 hour

In as little as 20 minutes after the last cigarette is smoked, the heart rate drops and returns to normal. Blood pressure begins to drop, and circulation may start to improve.

After 12 hours

After just 12 hours without a cigarette, the body cleanses itself of the excess carbon monoxide from the cigarettes. The carbon monoxide level returns to normal, increasing the body's oxygen levels.

After 1 day

Just 1 day after quitting smoking, the risk of heart attack begins to decrease.

In as little as 1 day after smoking cessation, a person's blood pressure begins to drop, decreasing the risk of heart disease from smoking-induced high blood pressure. In this short time, a person's oxygen levels will have risen, making physical activity and exercise easier to do, promoting heart-healthy habits.

After 2 days

Smoking damages the nerve endings responsible for the senses of smell and taste. In as little as 2 days after smoking cessation, a person may notice a heightened sense of smell and more vivid tastes as these nerves heal.

After 3 days

3 days after quitting smoking, the nicotine levels in a person's body are depleted. While it is healthier to have no nicotine in the body, this initial depletion can cause nicotine withdrawal.

Around 3 days after quitting, most people will experience moodiness and irritability, severe headaches, and cravings as the body readjusts.

After 1 week

In the first five to eight days you’ll experience three cue-induced cravings per day. If you normally lit up after a meal, it’s likely that will be the time you experience these cravings. You can fight these cravings by substituting something else, such as going for a walk, as these cravings typically don’t last more than three minutes.

After 2 weeks

Within two weeks the blood circulating in your gums and teeth will return to that of a nonsmoker. This helps heal periodontics and improve your breath.

After 1 month

In as little as 1 month, a person's lung function begins to improve. As the lungs heal and lung capacity improves, former smokers may notice less coughing and shortness of breath. Athletic endurance increases and former smokers may notice a renewed ability for cardiovascular activities, such as running and jumping.

After 1-3 months

For the next several months after quitting, circulation continues to improve.

After 9 months

The lungs have significantly healed themselves. The delicate, hair-like structures inside the lungs known as cilia have recovered from the toll cigarette smoke took on them. These structures help push mucus out of the lungs and help fight infections.

Many former smokers notice a decrease in the frequency of lung infections because the healed cilia can do their job more easily.

After 1 year

The risk of heart disease will decrease by half after quitting smoking for 1 year, and arteries and blood vessels will begin to widen after 5 years.

One year after quitting smoking, a person's risk for coronary heart disease decreases by half. This risk will continue to drop past the 1-year mark.

After 5 years

The body has healed itself enough for the arteries and blood vessels to begin to widen again. This widening means the blood is less likely to clot, lowering the risk of stroke.

The risk of stroke will continue to reduce over the next 10 years as the body heals more and more.

After 10 years

After 10 years, a person's chances of developing lung cancer and dying from it are roughly cut in half compared with someone who continues to smoke. The likelihood of developing mouth, throat, or pancreatic cancer has significantly reduced.

After 15 years

After 15 years of having quit smoking, the likelihood of developing coronary heart disease is the equivalent of a non-smoker. Similarly, the risk of developing pancreatic cancer has reduced to the same level as a non-smoker.

After 20 years

After 20 years, the risk of death from smoking-related causes, including both lung disease and cancer, drops to the level of a person who has never smoked in their life. Also, the risk of developing pancreatic cancer has reduced to that of someone who has never smoked.
