  Purpose

Secondhand smoke is the aged and diluted combination of smoke exhaled by a smoker and sidestream smoke (smoke from the lit end of a cigarette). Electronic cigarettes are different from tobacco-burning cigarettes in that they produce vapor, not smoke. For consistency with common usage, secondhand smoke (SHS) refers to true secondhand smoke from cigarettes and secondhand vapor from e-cigarettes.

The goals of this study are to increase understanding of the composition of SHS from e-cigarettes, quantitatively compare the amount of SHS generated by e-cigarettes and a market sample of commercial e-cigarettes to leading brand styles of commercial tobacco-burning cigarettes, and to quantitate the emission factors of e-cigarettes including the market-sample e-cigarettes.

Primary Outcome Measures:
  • To assess differences in levels of selected SHS constituents in an environmental test chamber after human smoking of e-cigarette #1, #2, and #3 compared to after human smoking of tobacco-burning cigarettes. [ Time Frame: 2 weeks for participants in Cohorts 1 and 2; and approximately 4 weeks for participants in Cohorts 3, 4, and 5 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To determine selected SHS constituent emission factors for each tobacco-burning cigarette, each e-cigarette, and the market-sample e-cigarettes (collectively). [ Time Frame: 2 weeks for participants in Cohorts 1, 2, and 6; and approximately 4 weeks for participants in Cohorts 3, 4, and 5 ] [ Designated as safety issue: No ]
  • To assess the differences in levels of selected SHS constituents in an environmental test chamber after human smoking of e-cigarettes and tobacco-burning cigarettes compared to after a non-smoking blank condition. [ Time Frame: 2 weeks for participants in Cohorts 1, 2, and 6; and approximately 4 weeks for participants in Cohorts 3, 4, and 5 ] [ Designated as safety issue: No ]
  • To assess differences in levels of additional selected SHS constituents in an environmental test chamber after human smoking of e-cigarettes compared to after human smoking of tobacco-burning cigarettes. [ Time Frame: 2 weeks for participants in Cohorts 1, 2, and 6; and approximately 4 weeks for participants in Cohorts 3, 4, and 5 ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   21 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  1. Able to read, understand, and willing to sign an Informed Consent Form (ICF) and complete questionnaires written in English.
  2. Generally healthy males or females, 21 years of age or older at Screening.
  3. Able to meet cohort-specific requirements as follows:

    Cohort 1 - Leading U.S. tobacco-burning non-menthol cigarette, and

    Cohort 2 - Leading U.S. tobacco-burning menthol cigarette:

    • self-reports at the Screening Visit smoking at least 5 cigarettes per day and inhaling the smoke, for at least 3 months prior to Screening
    • self-reports smoking Leading U.S. tobacco-burning non-menthol cigarette or Leading U.S. tobacco-burning menthol cigarette as UB cigarettes [UB cigarette is defined as the cigarette brand style currently smoked most frequently by the participant];

    Cohort 3 - Electronic cigarette #1 smokers, and

    Cohort 4 - Electronic cigarette #2 smokers:

    • self-reports at the Screening Visit smoking a non-menthol e-cigarette at least once per day, for at least 3 months prior to Screening;
    • willing to switch from using their current e-cigarette brand style to using a different e-cigarette brand style during the study;

    Cohort 5 - Electronic cigarette #3 smokers:

    • self-reports at the Screening Visit smoking a menthol e-cigarette at least once per day, for at least 3 months prior to Screening;
    • willing to switch from using their current e-cigarette brand style to using a different e-cigarette brand style during the study;

    Cohort 6 - U.S Market-sample electronic cigarette smokers:

    • self-reports at the Screening Visit smoking the selected U.S. market-sample e-cigarettes (menthol or non-menthol) at least once per day, for at least three months prior to Screening;
    • willing to continue exclusive use of their preferred style (flavor) of e-cigarette during the study.
  4. 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 or be surgically sterile for at least 90 days prior to enrollment;
  5. Able to safely perform the required study procedures, as determined by the Investigator.

Exclusion Criteria:

  1. Clinically significant or unstable/uncontrolled acute or chronic medical conditions at Screening, as determined by the Investigator, that would preclude a participant from participating safely in the study (e.g., hypertension, asthma, or other lung disease; cardiac disease; neurological disease; or psychiatric disorders) based on screening assessments such as safety labs and medical history or physical examination at Enrollment;
  2. Self-reports or safety labs indicate diabetes;
  3. At risk for heart disease, as determined by the Investigator;
  4. Use of medicine for treatment of depression or asthma;
  5. Systolic blood pressure of ≥150 mmHg or a diastolic blood pressure of ≥95 mmHg, measured after being seated for 5 minutes;
  6. Postponing a decision to quit smoking (defined as planning a quit attempt within 30 days of the Screening Visit) to participate in this study;
  7. Employed by a tobacco company, the study site, or environmental test chamber vendor;
  8. Females who have a positive pregnancy test, are pregnant, breastfeeding, or intend to become pregnant during the course of the study;
  9. History of claustrophobia;
  10. Regularly exposed to solvent fumes or gasoline (e.g., painter, gas-station mini mart employee);
  11. Determined by the Investigator to be inappropriate for this study, including a participant who is unable to communicate or unwilling to cooperate with the clinical staff.
