5. Study Description

Brief Summary
Randomized controlled trial of acute use of electronic cigarette effect on oxidative stress and inflammation.
Detailed Description
Participants will have an acute e-cig exposure on 2 occasions 1) e-cigarette 2) sham e-cig (empty e-cig) control. Blood will be collected before and after E-cig use and analyzed for biomarkers of inflammation and oxidative stress.
