I think nicotine, being the stimulate that it is, causes your blood vessels to constrict violently...so violently that scarring takes place over time. The more scarring that occurs, the more blockage that builds up, the more likely you are to have a heart attack.

The technology sounds cool, but I'll probably wait until it's available from another vendor.
