Brief Summary:
This trial studies biomarkers obtained by bronchoscopy (bronchoalveolar lavage and lung brushings) to determine the effect of smoking e-cigarettes on the lungs. Studying samples of lung cells from participants who smoke e-cigarettes may help doctors learn more about changes that occur in deoxyribonucleic acid and identify biomarkers related to cancer.
Detailed Description:
PRIMARY OBJECTIVES:
I. To assess inflammatory changes over 10 weeks for lung and urine biomarkers in smokers who undergo serial bronchoscopy. The randomized trial includes four conditions: continued use (n=32), complete switching to the nicotine standardized research electronic cigarettes (e-cig) (SREC) (n=32), complete switching to the placebo (nicotine free) SREC (n=32), and complete switching to nicotine replacement therapy (NRT)(n=32).
OUTLINE: Participants are randomized to 1 of 4 groups.
GROUP I: Participants undergo bronchoscopy over 30-60 minutes at baseline. Participants continue to smoke their usual brand of cigarettes. Participants undergo a second bronchoscopy on day 71.
GROUP II: Participants undergo bronchoscopy over 30-60 minutes at baseline. After the baseline bronchoscopy, participants learn to use the SREC with nicotine for 2 weeks and switch completely to the SREC with nicotine for 2 weeks and switch completely to the SREC with nicotine starting day 15 for 8 weeks. Participants undergo a second bronchoscopy on day 71.
GROUP III: Participants undergo bronchoscopy over 30-60 minutes at baseline. After the baseline bronchoscopy, participants learn to use the SREC without nicotine for 2 weeks and switch completely to the SREC without nicotine starting day 15 for 8 weeks. Participants will be offered varenicline to aid cessation. Participants undergo a second bronchoscopy on day 71.
GROUP IV: Participants undergo bronchoscopy over 30-60 minutes at baseline. Beginning 1 week before the day 15 quit date, participants stop smoking using NRT comprising either patch, gum, or lozenge for 8 weeks. Participants undergo a second bronchoscopy on day 71.
After completion of study, participants are followed up at 3 months.
