“Investigation of the Effects of Electronic Cigarettes on Vascular Health”
The goal is find out if the use of Electronic cigarettes (EC) leads to the same changes that we see in blood vessels of traditional cigarettes (TC) users. The investigators will also enroll non-smokers as "controls", against which they will measure changes in blood vessels in TC and EC users.

Behavioral - Electronic cigarette
During the first encounter, blood pressure and endothelium-dependent relaxation (EDR) will be measured by flow mediated dilatation (FMD), and a small peripheral IV catheter will be placed in the participant's median antecubital or cephalic vein. A blood sample (10 mL) for EPCs and F2-isoprostanes will be collected. One urine sample will also be collected for measurement of urinary F2-isoprostanes, cotinine and creatinine. These will serve as both baseline measures for subsequent acute exposure t ...read more on ClinicalTrials.org

Behavioral - (sham cigarette) - no actual exposure to cigarettes
During the first encounter, blood pressure and endothelium-dependent relaxation (EDR) will be measured by flow mediated dilatation (FMD), and a small peripheral IV catheter will be placed in the participant's median antecubital or cephalic vein. A blood sample (10 mL) for EPCs and F2-isoprostanes will be collected. One urine sample will also be collected for measurement of urinary F2-isoprostanes, cotinine and creatinine. These will be compared to the second set of laboratory measurements done a ...read more on ClinicalTrials.org
