Can the lungs change back to their original color after quitting smoking?

This is mainly related to the degree of damage. If the damage is minor, it may be possible. For these old smokers, not smoking is particularly cruel, but after quitting smoking, their physical condition is generally better, and then the color of their lungs can be brighter. Although it's not that fast, it's at least better than when you smoke, and your lung function can be better.

Depending on the degree of damage, maybe.

For smokers, the lungs are already in a dark state, which is a bad waste, so today it really hurts people and lungs. So if you can quit smoking, try to smoke as little as possible, because smoking is bad for your health and will discolor your lungs. We mainly see that if the injury is mild, we may be able to return to normal.

Not smoking is a particularly cruel thing, and it is difficult to quit.

For some old smokers, smoking is a common occurrence. If you don't smoke, it will be a particularly cruel thing, so it is very difficult to quit smoking, but smoking for a long time is not good for your lungs. In this case, your lungs are not red but black. So this kind of thing should be avoided as much as possible. Smoke less, you can still recover.

Not so soon, but at least.

For some people who smoke regularly, if they smoke for a while, it may be slightly better for their health, but at least it will be better than before. Smokers and non-smokers have completely different lung colors, so in this case, I suggest you smoke as little as possible, because smoking treatment is not good for your health. Quit smoking slowly, stop smoking, and get better slowly. You don't often want to smoke. It should be simple.
