  15, 30, 45, 60, 120, 180, 240, 300, 360 minutes

• Subjective effects scores for positive Product Effects (PE) with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence

  15, 30, 45, 60, 120, 180, 240, 300, 360 minutes

• Subjective effects scores for negative Product Effects (PE) with respect to initiation of in-clinic IP use following a 12-hour tobacco and nicotine abstinence

  Score subjective effects using a NRS to determine area under the negative PE score-versus-time curve (AUEC) and maximum negative PE score

  15, 30, 45, 60, 120, 180, 240, 300, 360 minutes

• Maximum change in pulse rate relative to baseline

  Determine the maximum change in pulse rate

  Baseline and at timed intervals over 360 minutes following initiation of IP use

• Change in expired carbon monoxide (ECO) relative to baseline

  Assess change in ECO from baseline following IP use

  Baseline and 35 minutes post-IP use

• Baseline cotinine measured pre-IP use

  Evaluate changes in baseline cotinine to assess whether subjects substantially changed their nicotine exposure during the study

  -0.5 minute only for each IP, over 5 weeks

Other Outcomes (2)

• Maximum change in blood pressure relative to baseline

  Baseline and at timed intervals over 360 minutes following initiation of IP use

• Perform both CYP2A6 genotyping and phenotyping (i.e., nicotine metabolic ratio of cotinine:3-OH cotinine)

  Time of randomization

Eligibility Criteria

• Age: 21 Years - 60 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• 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.

• 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.

• Willing to not participate for 60 days post-study in donation of blood samples or in any study that requires collection of blood samples.
• Females of childbearing potential must be willing to use a form of contraception acceptable to the Investigator from the time of signing informed consent until study discharge.

You may not qualify if:

• 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.
• A positive urine drug screen without disclosure of corresponding prescribed concomitant medication(s), at Screening or Randomization Visit. A positive alcohol result at Screening, Randomization Visit, or at any Test Visit.
