How long does it take for smoking to ruin your lungs?
So, is there a specific timeline for when the lungs start to be affected by smoking?
There isn't an exact timeline because it depends on several factors, such as the frequency and amount of smoking, as well as other health factors like genetics and pre-existing conditions. However, studies have shown that the risk for lung cancer increases after 15 years of smoking, while chronic bronchitis can develop after just a few years of heavy smoking.
