Brief periods of non-smoking (e.g., up to ~7 consecutive days due to illness, trying to quit, participation in a study or trial where smoking was prohibited) during that time will be permitted at the discretion of the PI 5. Currently smokes at least 10 manufactured combustible, non-menthol cigarettes per day (CPD), as self-reported at Screening visit. Subjects may also be dual-using cigarettes and ENDS products 6. Has a positive urine cotinine (= 200 ng/mL) at the Screening visit 7. Has an exhaled CO > 10 ppm at Screening visit 8. A female subject of childbearing potential must have been using one of the following forms of contraception and agree to continue using it through completion of the study: 8.1. Hormonal (e.g., oral, vaginal ring, transdermal patch, implant, or injection) consistently for at least 3 months prior to Assessment Day 1 8.2.

Exclusion criteria

Exclusion criteria: 1. Clinically relevant medical or psychiatric disorder, in the opinion of the Investigator. This includes any clinically significant concomitant disease or condition that could interfere with, or for which the treatment of might interfere with, the conduct of the study, or that would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study 2. Has a clinically significant abnormal finding on the physical examination, medical history, vital signs, ECG, or clinical laboratory results, in the opinion of an investigator 3.

Has a fever (> 100.5°F) at the Screening visit or on Assessment day(s) 5. Positive result for urine drugs of abuse test or alcohol breath test at the screening visit. If a positive urine drug test is observed, and it is believed the positive urine test is due to prescription drugs, the PI should obtain documentation that; 5.1. Confirms the subject’s use of the prescribed medication 5.2. The prescribed medication will cause a false positive drug test 6. Has or has a history of diabetes mellitus, asthma, or chronic obstructive pulmonary disease 7. Has a systolic blood pressure 150 mmHg, diastolic blood pressure 95 mmHg, or heart rate 99 bpm at Screening 8. Has experienced an allergic reaction following previous e-cigarette use or with exposure to any primary components of the e-liquids (nicotine, flavor, benzoic acid, propylene glycol and glycerol) 9.

Has participated in a previous clinical study or trial for an investigational drug, device, biologic, or tobacco product within 30 days prior to Day 1 11. Has donated blood or blood products, > 500 mL, had significant blood loss, or received whole blood or a blood product transfusion within 3 months prior to Assessment Day 1 12. If female, the subject is pregnant, has a positive serum pregnancy test at screening, is lactating, breastfeeding, or intends to become pregnant during the time period from Screening through the end of study 13. Has used medications known to interact with cytochrome P450 (CYP) 2A6 (including, but not limited to, amiodarone, amlodipine, amobarbital, buprenorphine, clofibrate, clotrimazole, desipramine, disulfiram, entacapone, fenofibrate, isoniazid, ketoconazole, letrozole, methimazole, methoxsalen, metyrapone, miconazole, modafinil, orphenadrine, pentobarbital, phenobarbital, pilocarpine, primidone, propoxyphene, quinidine, rifampicin, rifampin, secobarbital, selegiline, sulconazole, tioconazole, tranylcypromine) within 14 days or 5 half-lives of the drug, whichever is longer, prior to Assessment Day 1 14.

Design outcomes

Secondary

MeasureTime frame
1. Baseline-adjusted and unadjusted plasma nicotine PK parameters following the 5-minute ad libitum product use sessions for each study product. The following PK parameters will be determined: AUC0-60, Cmax and Tmax (unadjusted only). These will be determined following the measurement of blood (plasma) nicotine levels in samples drawn at the following timepoints relatives to initiation of the first inhalation: -5, 1.5, 3, 5, 6, 7, 8, 10, 15, 30 and 60 minutes. 2. Subjective effects following use of the study products, assessed using the modified product evaluation scale (mPES) at a single timepoint on each assessment day, immediately after completion of the 30-minute blood draw
