Once that tar coating is gone, lungs aren't used to feeling air that only has “normal” particles, like dust or pollen. Once this tar-free tissue is exposed to normal air particles, coughing and shortness of breath can occur.
Your lung function improves within two weeks to three months after the last cigarette. During the first year after quitting, coughing and shortness of breath decrease, and your lungs become better at cleaning themselves to reduce the risk of infection.

Coughing and shortness of breath decrease. Tiny hair-like structures (called cilia) that move mucus out of the lungs start to regain normal function, increasing their ability to handle mucus, clean the lungs, and reduce the risk of infection.
Try Breathing Exercises
Pursed lip breathing exercises help to release trapped air, keep airways open longer, improve the ease of breathing, and relieves shortness of breath. Diaphragmatic breathing exercises strengthen your diaphragm, slow your breathing rate, and decrease oxygen demand.
Shortness of breath does not always indicate that you are hypoxic. In other words, your level of dyspnea, or air hunger, does not always correlate with your oxygen saturation. This means that you can be short of breath, even extremely short of breath, even in the presence of normal oxygen saturation.
If your breathing has become labored and difficult for no obvious reason, it may be the sign of a more serious medical problem. If chest pain or pressure, fainting or nausea accompanies shortness of breath, you should treat it as a medical emergency.
Your lung function can improve by up-to 30%. You might notice the impact of this in a reduction in shortness of breath when exercising. The fibres in your lungs that help to reduce mucus build-up and protect against bacterial infection might start to grow back.
As a result, the cilia that remain have trouble sweeping mucus out of the lungs. When you stop smoking, the cilia regrow and become active again. As they recover and help move the mucus out of your lungs, you might cough more than usual. This might last for a few weeks or up to a year.

It depends very much on how much you smoked. So if you smoked, you know, one cigarette a day for maybe a year, probably your risk is very little. But if you smoked a pack a day for 20 years, then 20 to 30 years later you are still at risk.
Emphysema continues to progress even after people stop smoking. However, quitting smoking helps reduce symptoms and improve quality of life and life expectancy.
While lung tissue cells do regenerate, there's no way a smoker can return to having the lungs of a non-smoker. At best, they will carry a few scars from their time smoking, and at worst, they're stuck with certain breathing difficulties for the rest of their lives.
So How long does it take to stop? Once you've stopped smoking, it will take nicotine around 72 hours to leave your body- and the withdrawal symptoms you experience will take effect around 2-3 days after you quit.
Often, the first thing a doctor, nurse, or emergency medical technician will do is give you extra oxygen (called oxygen therapy). You get it through tubes in your nose or windpipe, or through a mask placed over your nose and mouth. This helps get more oxygen into your lungs and bloodstream.
If shortness of breath happens when you're clearly not exerting yourself, when you're doing something you normally could do without feeling winded, or comes on suddenly, those are warning signs that a heart issue could potentially be to blame.
