Investigation of the Effects of Electronic Cigarettes on Vascular Health
Stopped early · Not applicable · Has a placebo group
Conditions studied: Vascular Health
In brief
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.
