Summary
This trial is studying how smoking e-cigarettes affects the lungs by looking at changes in the DNA of lung cells.
Who is the study for?
This trial is for everyday smokers who have smoked at least 5 cigarettes a day for over a year, can read and consent to study procedures, and are in stable health. It's not for those with recent lung issues or procedures, pregnant/breastfeeding women, users of inhalants or antibiotics within specific timeframes, those allergic to certain substances like propylene glycol/glycerin or flavors, heavy marijuana users, individuals with kidney/liver disease or immune disorders.
What is being tested?
The trial is using bronchoscopy to collect lung cell samples from e-cigarette smokers to find biomarkers related to cancer. Participants will undergo bronchoalveolar lavage and brushings while also providing information through questionnaires about their smoking habits.
What are the potential side effects?
Potential side effects include discomfort from the bronchoscopy procedure such as sore throat or coughing. There may be risks associated with sedation used during the procedure (like lidocaine), including allergic reactions.

All Individual Drugs Already Approved
Therapies where all constituent drugs have already been approved are likely to have better-understood side effect profiles.
Approved for 5 Other Conditions
This treatment demonstrated efficacy for 5 other conditions.
No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
Trial Design
4Treatment groups
Experimental Treatment
Active Control
Group I: Group IV (Nicotine Replacement Therapy [NRT])Experimental Treatment4 Interventions
Participants undergo bronchoscopy over 30-60 minutes at baseline. One 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.
Group II: Group III (SREC without nicotine)Experimental Treatment4 Interventions
Participants undergo bronchoscopy over 30-60 minutes at baseline. Beginning 1 week after 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 III: Group II (SREC with nicotine)Experimental Treatment4 Interventions
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 starting day 15 for 8 weeks. Participants undergo a second bronchoscopy on day 71.
Group IV: Group I (usual cigarette brand)Active Control4 Interventions
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.
