Cigarettes have been around for decades and were first introduced in the United States in the early 19th century. Cigarettes gained popularity in the early 1900s and were even praised during WWI for helping the wounded relax and ease their pain.
Smoking was first linked to lung cancer in 1940 and the early 1950s. In 1954 the Surgeon General's scientific study determined a causal link between excessive cigarette smoke and lung cancer.
Tobacco use is the leading cause of preventable disease, disability, and death in the United States. Yet, 34 million US adults smoke cigarettes.
Below we have compiled some images of smokers' lungs after quitting smoking, and of the damage cigarettes and tobacco products can do to your lungs.
Lungs Before and After Smoking

The lung on the left is damaged from smoking, but after just a few weeks of being tobacco free, the lungs begin to repair themselves.
Cilia, microscopic hairs in the lungs, work to clear the tar, debire and other pollutants. This may lead to an uncomfortable cough and chest pain. Lungs begin to return to normal (pink, elastic) after you quit smoking
It takes anywhere from 1 to 9 months for cilia to repair themselves, longer for long term smokers. Things like diet and exercise can help repair your lungs over time.

Lung repair may happen faster than you think. While some smokers may have caused irreversible damage to their lungs, quitting smoking will always lead to improved lung function, even if they never return to how they were before smoking.
Smoking for Years and Then Quitting Smoking
As mentioned above, the lungs will begin to repair themselves just weeks after you quit and while quitting is by no means an easy process, the reduced risk of disease and death makes the decision all the more important, even if you have been smoking for decades.

After 30 years of smoking, the lungs will likely have irreversible damage and the risk of all types of disease is drastically increased, including lung cancer, COPD, and heart disease.
While the lungs may never return to normal, it is still worth quitting smoking even after 30 or more years.
What Does Smoking Do To Your Lungs?
Smoking can cause severe damage to your lungs and small air sacs called alveoli.
This damage leads to build of tar and other pollutants in your lungs which can cause discoloration and the blackening of lung tissue.
Smoking may cause lung diseases such as COPD, chronic bronchitis, emphysema and lung cancer.
Beyond lung damage smoking can cause heart disease, liver disease, mouth cancer and more.

How Long Does it Take for Tar to Leave Your Lungs?
Cigarettes contain many chemicals including nicotine, hydrogen cyanide, formaldehyde, lead, arsenic, ammonia, radioactive elements, benzene, carbon monoxide, tobacco-specific nitrosamines (TSNAs) and polycyclic aromatic hydrocarbons (PAHs).
When you inhale the cigarette smoke there is tar present while the product is being burned. The last puffs on a cigarette can contain twice as much tar as with the first puffs. This tar sticks to the cells in your lungs called the cilia and paralyzes them.
The main function of Cilia is to help move microbes and debris up and out of the airways. If cilia is paralyzed, you are more at risk to develop lung diseases such as emphysema, chronic bronchitis, and lung cancer.
After you quit smoking, your cilia begin to heal which takes 1 to 9 months. However, the tar that caused the damage in the first place can take even longer to leave your lungs.
How Long Does it Take for Lungs to Heal After Quitting Smoking?
Lung improvement begins after 2 weeks to 3 months.
Healing your lungs completely will take time and sometimes you are never completely healed from the damage.
The bottom line is that smoking, especially long term, has serious and often irreversible damage.
The sooner you quit smoking, the better chances you have to repair your lungs. There is no magic pill to heal your lungs after quitting.
Oftentimes if you have been smoking for decades, it can take decades for your lungs to heal.
But can lungs heal after 40 years of smoking?
While they will likely never return to normal, your lungs will begin to heal the moment you quit.
Can Lungs Go Back to Normal After Quitting Smoking?
Yes, your lungs can go back to normal after quitting smoking.
One large study found that after 20 years smoke-free, the risk of COPD drops to the same as if you have never smoked and after 30 years, the risk of lung cancer also drops to the same risk as non-smokers.
How to Clean Lungs After Quitting Smoking?
There is no magic pill or solution to clean your lungs after quitting smoking. This is mostly because of the extensive and internal damage smoking does to the body. That said, there are some things that can be done to help improve lung health.
-
Certain dietary restrictions - Avoid foods that promote and produce mucus such as dairy, processed foods, candies, and caffeine. Foods that help heal the lungs are pineapples, honey, citrus fruits, leafy greens, and radishes.
-
Breathing exercises - Breathing exercises can help clean your lungs out. Pursed-lip breathing can be done by slowly inhaling through the nose for about 2 seconds and then exhaling through the mouth with tight lips for about 4 seconds.
-
Physical exercises - Physical exercise gets blood moving and that includes blood surrounding the lungs. This helps activate the cilia to then move out debris that is stuck in your lungs from smoking.
-
Avoiding certain triggers - Other triggers to avoid include other smokers, secondhand smoke, cleaning materials (liquids) may aggravate your lungs, strong perfumes, and fires or wood burning stoves.
