More of the same. Can't leave them alone for a minute. When a person stops smoking the adverse effects strats reversing immediately. Wihtin three days, the senses that were dulled by the displaced oxygen of hemoglobin, returns. With increased oxygen in the blood the senses and brain are reinfused and working at maximum again. After that the lungs, which have an incredible ability to clean themselves of air pollution start to do exactly that. The smallest spaces of the lungs, the alveoli, start to exchange oxygen and carbon dioxide to their fullest extent.
The average 'tidal' volume of any breath is about 500 cc. That is a half a liter of air moving in and out with each breath. When severe lung disease like Chornic Obstructive Pulmonary Disease occurs due to cigarette smoking, frequently the ONLY air exchange that occurs is the tidal volume. See the lungs have a lot of air in them at any given time. If the lungs CLEARED of all the air with every breath one would be chronically short of breath. The 'residual' amount of air in lungs can be as much as 2000 cc. But, the 'tidal' volume is only 500 cc as average.
These severe lung diseases literally destroys alveoli. When the alveoli are gone there can be no air exchange. When 'end stage' strikes of any of these diseases all too often the residual air in the lungs is gone and only the tidal volume exists. As time goes on that volume gets smaller and smaller. The average 'end state' of lung disease has a tidal volume of 240 cc before they die. The only air in the lungs is that supplemented with oxygen. The average pulse oximeter reading of people at 'end state' is about 84 to 85 percent. Normal is as close to 100% as a person can get. A chronic hypoxia exists. It's a horrible existance.
If you don't smoke, don't start.
If you do smoke, stop.
Lung disease takes your breath away. Better your 'soul mate' have that 'thrill' rather than the business of tobacco. Live a lifestyle of health and not anti-health.
