Outcome Measures

Primary Outcomes (1)

  • Changes in arterial stiffness and endothelial function with e-cigarette use.

    Arterial stiffness and endothelial function are two of the subclinical markers of vascular dysfunction

    Immediately Post, 1 hour, and 2 hour.

Study Arms (3)

E-Cigarette 5.4% NBV

ACTIVE COMPARATOR

Subjects will be asked to inhale an E-Cigarette with 5.4% NBV for 6 min.

Drug: E-cigarette

E-Cigarette 0% NBV

PLACEBO COMPARATOR

Subjects will be asked to inhale an E-Cigarette with 0% NBV for 6 min.

Drug: Nicotine 0%

Menthol Inhaler

PLACEBO COMPARATOR

Subjects will be asked to inhale a sham methole inhaler (that looks identical in looks to E-cigarette) for 6 minutes. This arm is to control for a potential effect of menthole.

Drug: Menthol Inhalant Product

Interventions

E-Cigarette containing 5.4% nicotine will be administered to determine the effects on vascular function.

Also known as: Nicotine 5.4%
E-Cigarette 5.4% NBV

E-Cigarette containing 0% nicotine will be administered to determine the effects on vascular function.

Also known as: Placebo
E-Cigarette 0% NBV

Menthol inhaler will be administered to determine the effects on vascular function.
