Very Low Nicotine Content Cigarettes and E-Cigarettes in Promoting Smoking Cessation in Daily and Intermittent Cigarette Smokers

Evaluating Concomitant Use of Very Low Nicotine Content Cigarettes and E-Cigarettes Among Daily and Non-Daily Smokers

This trial studies what would happen if the nicotine levels in cigarettes are greatly reduced, but electronic cigarettes containing different amount of nicotine are available. Different levels of nicotine may effect certain behaviors, including withdrawal symptoms, nicotine cravings, and mood and may lead to changes in smoking behavior in current daily and intermittent smokers..

Study Overview

• Status: Active, not recruiting
• Conditions: Cigarette Smoking-Related Carcinoma; Tobacco-Related Carcinoma
• Intervention / Treatment: Other: Questionnaire Administration; Other: Survey Administration; Drug: Cigarette; Drug: Nicotine Replacement; Drug: Very Low Nicotine Content Cigarette; Device: ECIG-Hi; Device: ECIG-Lo

Detailed Description

PRIMARY OBJECTIVES:

I. To characterize the effects of switching to VLNCCs plus ECIG-Hi or ECIG-Lo nicotine doses on abuse liability among daily and intermittent smokers.

EXPLORATORY OBJECTIVES:

I. To explore the effects of switching to VLNCCs plus ECIG-Hi or ECIG-Lo nicotine doses on abuse liability using biochemical measures of product use, compensation, and toxicant exposure, and self-reported measures of withdrawal, craving, affect, and satisfaction.

II. To explore the effects of switching from usual-brand cigarettes to VLNCCs, and from VLNCCs to VLNCC+ECIGs on measures of abuse liability.

III. To characterize the effects of dual use of VLNCC and JUUL ECIGs on abuse liability.

OUTLINE:

PHASE I: Patients smoke their usual cigarettes brand during week 1.

PHASE II: Patients smoke VLNCC cigarettes provided during weeks 2-4.

PHASES III-IV: Patients are randomized to 1 of 2 arms.

ARM I: Patients smoke ECIG-high (Hi) for 3 weeks and then ECIG-low (Lo) for 3 weeks

ARM II: Patients smoke ECIG-Lo for 3 weeks and then ECIG-Hi for 3 weeks.

After completion of study, patients are followed up for 30 days.

Exclusion Criteria:

• Unwilling to refrain from other e-cigarette use for the duration of the study, other than what is provided to them for study purposes

• Current/recent use of certain medications:

  • Smoking cessation meds (past 90 days; e.g., wellbutrin, bupropion, Zyban, nicotine replacement therapy [NRT], Chantix)
  • Certain medications to treat depression (last 14 days; e.g., amitriptyline)
  • A case by case determination will be made by study physician for medication on the precautionary list, (e.g. nitroglycerin)
  • Self-reported daily use of opioids for 30 days or more on phone screen or at screening is exclusionary however pro re nata (PRN) use is allowed (e.g., 3 to 7 days per week or less or if more frequent, use less than a month's duration
• Unstable medical condition as determined by the medical team

  • Barrier methods (such as condom or diaphragm) used with a spermicide, or
  • An intrauterine device (IUD)
  • Contraceptives sold for emergency use after unprotected sex are not acceptable methods for routine use
• Subject considered by the investigator to be unsuitable to participate in the study (e.g., due to cognitive deficits or instability to last the entire duration of the study)
