• Has been a daily ENDS consumer for at least 3 months prior to Screening and through Check-in. Brief periods of abstinence (e.g., up to \~7 consecutive days due to illness, trying to quit, participation in a study where vaping was prohibited) ≥ 30 days prior to Screening will be permitted at the discretion of an Investigator.
• Reports weekly use of at least 3 mL of e-liquid from an ENDS product at Screening.
• Has a urine cotinine concentration ≥ of 200 ng/mL at Screening and Check-in.
• Has an exhaled carbon monoxide (ECO) concentration \< 10 ppm at Check-in.
• If female, must meet one of the following criteria:
• If of childbearing potential - agrees to use one of the accepted contraceptive regimens from at least 30 days prior to the first product use, during the study, and for at least 30 days after the last product use. An acceptable method of contraception includes one of the following: abstinence from heterosexual intercourse, hormonal contraceptives (birth control pills, injectable/implant/insertable hormonal birth control products, transdermal patch), intrauterine device (with or without hormones) OR agrees to use a double barrier method (e.g. condom and spermicide) during the study and for at least 30 days after the last product use.
• If a female of non-childbearing potential - should be surgically sterile (i.e. has undergone complete hysterectomy, bilateral oophorectomy, or tubal ligation/occlusion) or in a menopausal state (at least 1 year without menses), as confirmed by FSH levels (≥ 40 mIU/mL).
• Is willing to comply with the requirements of the study.

You may not qualify if:

• Has a history or presence of clinically significant uncontrolled gastrointestinal, renal, hepatic, neurologic, hematologic, endocrine, oncologic, urologic, pulmonary, immunologic, psychiatric, or cardiovascular disease, or any other condition that would jeopardize the safety of the subject or impact the validity of the study results.
• Has a clinically significant abnormal finding on the physical examination, medical history, vital signs, ECG, or clinical laboratory results.
• Has a positive test for HIV-1/HIV-2 Antibodies, Hepatitis B surface Antigen, or Hepatitis C Antibody.
• Has had an acute illness (e.g., upper respiratory infection, viral infection) within 14 days prior to Check-in.
• Has a fever (\> 100.5°F) at Screening or Check-in.
• Has a positive COVID-19 test during the screening period, prior to Check-in.
• Has a body mass index greater than 40.0 kg/m2 or less than 18.0 kg/m2 at Screening.
• Has a history of drug or alcohol abuse within 12 months of Screening.
• Has a systolic BP \< 90 mmHg or \> 150 mmHg, diastolic BP \< 40 mmHg or \> 95 mmHg, or HR \< 40 bpm or \> 99 bpm at Screening.
• Is allergic to or intolerant of components of the product e-liquid, including but not limited to, menthol, propylene glycol or glycerin.
• Is unable to use the CReSS topography device with the vaping device during the training session on Day -1.
• Has an estimated creatinine clearance \< 70 mL/minute (using the Cockcroft Gault equation) at Screening.
• Has a positive urine drug or alcohol test at Screening or Check-in. A positive test result for cannabinoids may be permitted if the result to the cannabis intoxication evaluation is negative at Check-in.
• If female, has a positive pregnancy test, is breastfeeding or lactating, or intends to become pregnant from Screening through Day 5.
• Has been treated for depression, diabetes, asthma, emphysema, or chronic obstructive pulmonary disease within 12 months of Check-in.
