Investigating Vaped Phenanthrene Biomarkers in Former Smokers

Status: Recruiting

Former smokers continue to be at higher risk for developing lung cancer than non-smokers,even years after quitting. This study will look at how a specific chemical, phenanthrene, is broken down in former smokers and non-smokers. If former smokers break down this chemical in a more harmful way, it might help explain their increased risk for lung cancer. Study participants will be asked to attend an in-person study visit to vape a small amount of phenanthrene. You'll then be given supplies to collect your urine for 24 hours afterwards.
