About this study
Official title: A Single-Center Evaluation of Environmental Emissions From Electronic Cigarettes and Tobacco-Burning Cigarettes
This study will assess environmental emissions of selected compounds in a test chamber after cigarette smoking or e-cigarette vaping.
Read the detailed description
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 1) increase understanding of the composition of SHS from e-cigarettes, 2) 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 3) quantitate the emission factors of e-cigarettes including the market-sample e-cigarettes.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 2 weeks for participants in Cohorts 1 and 2; and approximately 4 weeks for participants in Cohorts 3, 4, and 5
Secondary outcomes (3)
To determine selected SHS constituent emission factors for each tobacco-burning cigarette, each e-cigarette, and the market-sample e-cigarettes (collectively).
Measured: 2 weeks for participants in Cohorts 1, 2, and 6; and approximately 4 weeks for participants in Cohorts 3, 4, and 5
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.
Measured: 2 weeks for participants in Cohorts 1, 2, and 6; and approximately 4 weeks for participants in Cohorts 3, 4, and 5
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.
Measured: 2 weeks for participants in Cohorts 1, 2, and 6; and approximately 4 weeks for participants in Cohorts 3, 4, and 5

What is this clinical trial studying?
A study testing Leading U.S. non-menthol cigarette, Leading U.S. menthol cigarette and Electronic cigarette #1 in people with Smoking, run by R.J. Reynolds Vapor Company at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2018; AzTrials last refreshed its copy on 7 Nov 2026.
