Brief Summary

This study investigates the feasibility, acceptability, and short-term effects of providing 4 weeks of complimentary electronic cigarettes (ECs) to 30 individuals who did not quit after smoking cessation treatment provided in the context of lung cancer screening and do not plan to quit smoking. This open-label single-arm pilot clinical trial will test the impact of EC provision on: 1) study feasibility, 2) EC acceptability, 3) tobacco use behavior (e.g., cigarettes per day, EC use), and 4) biomarkers (e.g., carbon monoxide, cotinine, and anabasine). Participants will be asked to switch from combustible cigarettes to the NJOY ACE 5% nicotine electronic cigarette (EC) for 4 weeks. They will be followed an additional 4 weeks after EC provision ends (to 8 weeks). The first study hypothesis is that more than 40% of eligible smokers who are offered participation in the trial will enroll, and that 75% of enrollees will complete the trial. The second study hypothesis is that participants will report fewer cigarettes smoked per day at the end of 4 weeks of EC provision, relative to their baseline values.

Outcome Measures

Primary Outcomes (2)

  • Study Feasibility

    Participant enrollment, measured by the proportion of eligible participants who enroll in the study. Retention is measured by weeks of study participation.

    4 weeks

  • Cigarettes Per Day (CPD) Smoked During the Period of E-cigarette Provision

    Change in self-reported CPD smoked in the past week assessed using timeline follow-back (TLFB) between baseline and end of e-cigarette provision (Baseline vs.Week 4)

    4 weeks

Secondary Outcomes (2)

  • Carbon Monoxide (CO) Concentration in Expired Air

    4 weeks

  • Cigarettes Smoked Per Day After E-cigarette Provision Ends

    4 weeks (Weeks 4-8)

Study Arms (1)

NJOY ACE e-cigarette provision

EXPERIMENTAL

Device: NJOY ACE e-cigarette, 5% nicotine in tobacco flavor Patients will be provided with a NJOY ACE electronic cigarette for 4 weeks and asked to use the NJOY ACE as a substitute for smoking combustible cigarettes during the 4 weeks.

Other: NJOY ACE e-cigarette

Interventions

Patients will be provided with NJOY ACE electronic cigarettes and 5% nicotine e-liquid cartridges in tobacco flavor for 4 weeks and asked to use the electronic cigarette as a substitute for smoking combustible cigarettes during the 4 weeks

You may qualify if:

  • Participants who completed the Screen Assist study (NCT03611881) and self-reported smoking cigarettes at the end of the study were asked to complete a survey to ascertain their potential interest in participating in a research study to test the effects of switching from combustible cigarettes (CC) to electronic cigarettes (EC). Individuals who expressed interest in switching to EC on that survey were screened for eligibility for this pilot study
