Brief summary
The overall aim of the study is to evaluate the provision of e-cigarette (EC) versus NRT on smoking behavior, product use patterns and continued use, and iCO, a biomarker of toxicant exposure, among a sample of recent QL treatment failures. We will randomly assign N=372 smokers (targeted accrual) to EC (n=186) or QL treatment as usual with combination nicotine replacement therapy (NRT; n=186). All participants will receive three calls from QL coaches and EC and NRT will be provided at no cost for 8 weeks. The final follow-up will occur 12-weeks post baseline.
Detailed description
There remains a lack of prospective and controlled research on the behavioral, toxicological, and physiological effects of electronic cigarettes (ECs) to help the public health community come to a clear and accurate consensus on their risk-benefit. In order to successfully execute the proposed study, the investigators plan to recruit and enroll recent smoking cessation treatment failures from a state QL, which predominately serves priority populations (e.g., low socioeconomic status, high levels of mental health conditions). The proposed study will randomly assign smokers who were recent QL treatment failures to a) EC (JUUL 5%) or b) QL treatment as usual with combination nicotine replacement therapy control (NRT).
Interventions
DEVICEJUUL
Participants randomized to the JUUL group will receive either tobacco or menthol flavored JUUL with 5% nicotine. Will also receive counseling.
OTHERTreatment As Usual
Nicotine Replacement Therapy consisting of nicotine patches and lozenge along with standard quitline counseling.

| Proportion of Participants With iCO (Portable Carbon Monoxide Monitor) Verified Abstinence | 12 weeks | Intent to treat biochemically verified abstinence rates - participants reporting both 7-day point prevalence abstinence and an iCO reading less than or equal to 8. A portable exhaled carbon monoxide detector confirms daily smoking status. Used to evaluate changes iCO, a biomarker of tobacco constituent exposure and other health effects. |

|---|---|---|
| Sociodemographic Questionnaire - Employment Status | Baseline | Assess participant employment status from the sociodemographic questionnaire |
| Cigarette/EC Dependency Scale | 12 weeks | Assess e-cigarette and cigarette dependence. Scores range from 5 to 25 with higher scores indicating a greater level of dependence. |
| Drug Effects/Liking Questionnaire | 12 weeks | Assess the desire and liking of products, positive and negative effects (i.e., side effects), and perceived strength and effectiveness Scores range from 1 to 5 with higher scores indicating greater strength (effect from smoking cigarettes/vaping e-cigarettes) or liking (liking of effect from smoking cigarettes/vaping e-cigarettes) |
| Cigarette Purchase Task - Breakpoint | Week 1 (Baseline) | Asks participants how much they would be willing to pay (ranging from 0¢ to $1,120) for a puff of their own brand cigarette.

| Tiffany-Drobes Questionnaire of Smoking Urges: Brief Form (QSU) | 12 Weeks | Smoking and vaping urges/craving will be measured using the Tiffany-Drobes Questionnaire of Smoking Urges: Brief Form with a modified version (replacing the word cigarette with e-cigarette) for EC users. This is a 10-item measure where participants rate smoking/vaping-related items on a 7-point Likert scale ranging from 1 (strongly disagree) to 7 (strongly agree). Similar to previous studies, we will collapse the items into two previously identified factors (Factor 1: strong desire and intention to smoke/vape; Factor 2: anticipation of relief from withdrawal symptoms). Scores are calculated by summing the items and range from 5 to 35 for each of the factors with higher scores indicating greater craving to smoke/vape. |
