About this study

Official title: Randomized Trial of Low Nicotine Cigarettes Plus Electronic Cigarettes in Smokers

This study aims to determine the health effects of very low nicotine content in cigarettes, in conjunction with the availability of nicotine-containing electronic cigarettes (e-cigs) among smokers with mental health conditions (SMHC).

Read the detailed description

The specific objective of this study is to recruit a cohort of 240 current exclusive daily SMHC (diagnosed using the MINI International Neuropsychiatric Interview) and to measure a comprehensive battery of behavioral and health indicators at 4, 8, 12 and 16 weeks after being randomized to use either normal nicotine content (NNC) Spectrum cigarettes (11.6 mg nicotine/cigarette) or very low nicotine content (VLNC) Spectrum cigarettes (0.2 mg nicotine/cigarette) while also having access to an electronic cigarette (containing either 0 nicotine or high nicotine e-liquid) in a randomized double-blind, placebo-controlled, 2 by 2 design. All participants will be followed up with a study visit 4 weeks after the final randomized visit to identify whether they have continued to use e-cigs/cigarettes and to assess their motivation in smoking abstinence.

Our central hypothesis is that key markers of harms to health (e.g. urinary NNAL, exhaled carbon monoxide, measures of addiction, and mental distress) will be significantly improved among SMHC who are provided VLNC cigarettes and high nicotine e-cigs.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Urinary NNAL (4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol)

    Measure of tobacco-specific nitrosamine

    Measured: Week 16

Secondary outcomes (5)
  1. Exhaled Carbon Monoxide

    Measure of cigarette smoke exposure

    Measured: Week 16

  2. Kessler-6 Score

    Measure of serious psychological distress. This scale is a brief, self-report tool used to assess psychological distress. Scores range from 0-24, with higher scores indicating greater distress

    Measured: Week 16

  3. Penn State Cigarette Dependence Index

    Measure of cigarette dependence. This 10-item scale (with scores ranging from 0 to 20) was developed to measure cigarette dependence, where a score of 0 indicates no cigarette dependence and 20 indicates maximum cigarette dependence.

    Measured: Week 16

  4. Penn State Electronic Cigarette Dependence Index

    Measure of e-cigarette dependence. This 10-item scale (with scores ranging from 0 to 20) was developed to measure e-cigarette dependence, where a score of 0 indicates no cigarette dependence and 20 indicates maximum e-cigarette dependence.

    Measured: Week 16

  5. Cigarette Abstinence

    No cigarette use in the past 7 days and exhaled carbon monoxide < 6ppm

    Measured: Week 20

Questions about this trial

What is this clinical trial studying?

A study testing Normal Nicotine Content research cigarettes, High Nicotine e-cigarette and Very Low Nicotine Content research cigarettes in people with Tobacco Dependence, run by Milton S. Hershey Medical Center 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 11 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 11 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Urinary NNAL (4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol) (time frame: Week 16). 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 11 Sep 2025.
