Longer term smoking can cause damage to those alveoli or not. Depends on how much and how long you smoked.
When you smoke you basically burn off the cilia. These cilia are what help you remove phlegm from your lungs. I have a 13 pack year history of smoking. When I quit, the cilia grew back and I didn’t damage the avolei. So under your reference point, the lungs did self heal.
But, you damage the alveoli. That’s it. They are forever damaged.
