NCT03126357

Brief Summary

This study will examine elements of abuse liability (AL) related to potential product adoption of three electronic tobacco vapor products by current smokers relative to high and low AL comparator products (usual brand cigarette and nicotine gum, respectively). Changes in subjective measures, speed and amount of nicotine uptake, and maximum changes in physiological effects during and after product use that follows a 12-hour (minimum) tobacco and nicotine abstinence period, will be determined. The electronic tobacco vapor products will not be compared to each other.

  • Positive test for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV).
  • History or presence of hemophilia or any other bleeding disorders.
  • History or presence of clotting disorders and/or use of anticoagulants (e.g., clopidogrel \[Plavix®\], warfarin \[Coumadin®, Jantoven®\] and aspirin \[\> 325 mg/day\], see Section 7.4 "Concomitant Medications").
