Summary

This study will compare how former smokers and never-smokers break down a chemical called phenanthrene in their lungs. Researchers want to see if former smokers process this chemical through more harmful pathways, which could explain their higher risk of lung cancer even years after quitting. About 100 healthy adults who have tried vaping will take part, and the results may help develop better ways to prevent or treat lung cancer in the future.
