A study by the Wellcome Sanger Institute and University College London, published in the journal Nature, claims that the lungs of ex-smokers can regenerate, erasing the damage from addiction. After a few years of abstinence, the body creates a reservoir of healthy cells.

This study gives hope to those who, after many years of addiction, thought they had reached a point of no return.

To reach this conclusion, the researchers looked for DNA mutations in children, adults who never smoked, smokers and ex-smokers.

The results showed that, in the case of ex-smokers, cells that were once genetically modified, had once again become healthy cells, identical to those who never smoked.
