In each of 3 test sessions, subjects in each arm will receive a randomized sequence of three intravenous infusions (30 sec each), one hour apart. The infusions will consist of saline, nicotine (.25 mg / 70kg) and nicotine (0.5 mg / 70 kg). The randomized sequence will remain the same between test sessions for a given subject.
In each of 3 test sessions, subjects will take 6 inhalations from the study e-cigarette, one inhalation every 15 seconds, of the randomized menthol condition for that test session ust prior to each intravenous infusion. The menthol conditions are: 3.2% menthol, 0.5% menthol and tobacco-flavor only (0.0% menthol)
