Brief Summary
This will be a randomized, open-label, 8-way crossover, single-site study designed to evaluate elements of abuse liability (AL), including subjective effects and physiological measures (pharmacodynamics \[PD\]), and plasma nicotine uptake (pharmacokinetics \[PK\]) during and following ad libitum use of Electronic Nicotine Delivery System (ENDS) investigational products (IPs) in a confinement setting by generally healthy adult smokers of combustible cigarettes and dual users of cigarettes and ENDS products.

- Willing to abstain from tobacco and nicotine use for at least 12 hours prior to each test session.
- Females must be willing to use a form of contraception acceptable to the PI from the time of signing informed consent until End-of-Study.

- Weight of ≤ 110 pounds at Screening.
- Hemoglobin level is \< 12.5 g/dL for females or \<13.0 g/dL for males at Screening.
- Scheduled treatment for asthma currently or within the past consecutive 12 months prior to the Screening Visit. As-needed treatment, such as inhalers, may be included at the PI's discretion.
- Positive test for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV).

- Must not be a current regular user (i.e., \> 5 times per month) of any tobacco products other than cigarettes or ENDS within the last 6 months prior to screening.
- Use of any medication or substance that aids in smoking cessation, including but not limited to any NRT (e.g., nicotine gum, lozenge, patch), varenicline (Chantix®), bupropion (Wellbutrin®, Zyban®), GLP-1 agonists (e.g., Wegovy®, Mounjaro®, and Ozempic®), or lobelia extract within ≤ 30 days prior to the signing of informed consent.
- History or presence of bleeding or clotting disorders.
- Use of daily aspirin (≥ 325 mg) or other daily anticoagulants.
- Whole blood donation within 8 weeks (≤ 56 days) prior to the signing of informed consent and between Screening and check-in Day 1.
- NOTE: Participants will be advised against scheduling a whole blood donation for at least 7 days following study completion.
