About this study

This study will evaluate a reward devaluation strategy in which smokers use the JUUL e-cigarette immediately before any combustible cigarettes (CCs) are smoked. This procedure is predicted to accomplish three goals: 1) the rewarding effects of CC will be disrupted because subjects will already have attained fairly high peak nicotine concentrations immediately before smoking the cigarette. This reduces the rewarding effect of smoking, in part from receptor desensitization that occurs following nicotine exposure, which reduces the response to a subsequent dose of nicotine, and in part from satiating the drive to smoke; 2) the use of the JUUL will become associated with the same cues that elicit smoking, thereby promoting the substitution of JUUL use for CC use; and 3) ad libitum nicotine intake from the JUUL and its rewarding effects will be maximized because, unlike CC, they will be experienced after a period of nicotine deprivation. Thus, despite a lower per-puff nicotine dose relative to CC, the pharmacologic impact and reinforcing effect will be maximized. The study will evaluate two flavors (Mint and Virginia Tobacco), randomly assigned, to determine if flavor assignment (similar to the subjects' usual brand of CC or different than the subjects usual brand CC) has an effect on the success of this reconditioning procedure.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • JUULOther

    Subjects will be instructed to use the JUUL as often as they like during the 12-week product use period. They will also be instructed to use JUUL immediately before each cigarette to relieve their craving as much as possible before smoking their usual brand. The JUUL will also be the first product that they are instructed to use each morning. Smokers will be told to try to completely substitute JUUL for cigarettes by the end of the first week of use.

What is being measured

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

  1. Effects of Devaluation on Switching From Cigarettes to the JUUL E-cigarette

    Biochemically verified smoking abstinence during weeks 9-12, i.e., self-report of no smoking confirmed by an expired air CO reading of <5 ppm.

    Measured: During Weeks 9-12

Secondary outcomes (1)
  1. Changes in Cigarette Reward With Subsequent Switching Behavior

    Characterize changes in the two primary scales of the Cigarette Evaluation Questionnaire (mCEQ), assessing smoking satisfaction and psychological reward, over the first week of the study period. The mCEQ uses a 7-point scale (0=Not at all; 1=Very little; 2=A little; 3=Moderately; 4=A lot, 5=Quite a lot; 6=Extremely) to measure all subscales: Satisfaction, Psychological Reward, Enjoyment of Respiratory Tract Sensations, Craving Reduction, Aversion. Both subscales have the same "7-point scale" range.

    Measured: Week 1

Questions about this trial

What is this clinical trial studying?

A study testing JUUL in people with Smoking Cessation and Harm Reduction, run by Rose Research Center, LLC at 2 sites 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 7 inclusion and 14 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 20 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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 20 Apr 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?

Effects of Devaluation on Switching From Cigarettes to the JUUL E-cigarette (time frame: During Weeks 9-12). 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 20 Apr 2025; AzTrials last refreshed its copy on 26 Oct 2026.
