Plain-language summary
The purpose of this study is to measure plasma nicotine uptake parameters, physiological measures, and subjective effect measures in smokers during and following a single ad libitum use of three electronic cigarettes versus combustible cigarettes and nicotine gum.

Inclusion criteria
. Able to read, understand, and willing to sign an informed consent form and complete questionnaires written in English.
. Generally healthy male or female, 21 to 60 years of age, inclusive, at Screening.
. Expired breath carbon monoxide (ECO) level is ≥ 15 ppm and ≤ 100 ppm at the Screening and Randomization Visits, measured between 12 p.m. and 6 p.m.
. Cigarettes are the only tobacco product used within (≤) 30 days of Screening.
. Smokes combustible, filtered, non-menthol cigarettes, 83 mm to 100 mm in length.
. Agrees to smoke usual brand (UB) cigarette throughout the study period. Usual brand cigarette is defined as the cigarette brand style currently smoked most frequently by the subject.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Nicotine pharmacokinetics with respect to initiation of in-clinic investigational product (IP) use following a 12-hour tobacco and nicotine abstinence
Subjective effects scores for Intent to Use Again (IUA) with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence
. Smokes at least 10 cigarettes per day (on average) and inhales the smoke, for at least 6 months prior to Screening. Brief periods of abstinence due to illness, quit attempt (prior to 30 days of Screening), or clinical study participation (prior to 30 days of Screening) will be allowed at the discretion of the Investigator.
. Response at Screening to Fagerstrom Test for Nicotine Dependence, Question 1 ("How soon after you wake up do you smoke your first cigarette?") is either "Within 5 minutes" or "6 - 30 minutes."
Exclusion criteria
. Clinically significant or unstable/uncontrolled acute or chronic medical conditions at Screening, as determined by the Investigator, that would preclude a subject from participating safely in the study (e.g., uncontrolled hypertension, asthma or other lung disease, cardiac disease, neurological disease or psychiatric disorders) based on safety assessments such as clinical laboratory tests, medical history, and physical/oral examinations.
. Systolic blood pressure of \> 150 mmHg or a diastolic blood pressure of \> 95 mmHg at Screening, measured after being seated for at least 5 minutes.
. Hemoglobin level is \< 12 g/dL at Screening.
. Positive test for Human Immunodeficiency Virus (HIV), Hepatitis B surface antigen, or Hepatitis C virus.
. Postponing a decision to quit smoking (defined as planning a quit attempt within \[≤\] 30 days of Screening) to participate in this study or previous attempt within (≤) 30 days prior to Screening.
. Employed by a tobacco company, the study site, or handles unprocessed tobacco as part of their job.
. Use of any medication or supplement that aids smoking cessation, including but not limited to any nicotine replacement therapy (e.g., nicotine gum, lozenge, patch), varenicline (Chantix), bupropion (Wellbutrin, Zyban), or lobelia extract within (≤) 30 days of Screening.
. Females ≥ 35 years of age currently using systemic, estrogen containing contraception or hormone replacement therapy.
