Clinical Trial Summary

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.

2. PHQ-9 score greater than 9, or a score greater than 0 on item #9 ("Thoughts that you would be better off dead, or of hurting yourself in some way") at screening.

9. Use of any of these products in the past 30 days:

1. Illegal drugs (or if the urine drug screen is positive for cocaine, THC, amphetamines, methamphetamines, or opiates);

2. Experimental (investigational) drugs that are unknown to the subject;

3. Chronic opiate use.

10. Use of smokeless tobacco (chewing tobacco, snuff), cigars (except for "Black & Mild" cigars or Cigarillos), pipes, hookah, e-cigarettes, nicotine replacement therapy or other smoking cessation treatments within 14 days of screening.

11. Pregnant or nursing (by self-report) or positive pregnancy test.

Study Design


Intervention

Other:
JUUL
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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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. Week 12
Secondary 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 the following subscales: Satisfaction, Psychological Reward, Enjoyment of Respiratory Tract Sensations, Craving Reduction, Aversion. Week 1
