Conditions
Brief summary
This is a randomized, parallel-group open-label trial to evaluate respiratory symptoms in ENDS users switching from banned flavors to a non-banned flavor (tobacco) or 'tobacco free' nicotine pouches.
Interventions
Participants use an electronic nicotine delivery system with an assigned tobacco-flavored e-liquid
participants will use tobacco free oral nicotine pouches

Eligibility
Inclusion criteria
* ENDS users as determined by: (a) using banned flavored ENDS with nicotine such as fruit, candy, dessert flavors, and/or any product that indicates such flavors (b) using ENDS daily, regularly for the past 6 months (self-reported). * No smoking tobacco or using smokeless tobacco for the past 6 months. * Subjects should be free of acute respiratory illness within the proceeding 30 days prior to recruitment (self-reported). * Participant must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure. * After receiving information regarding the NYS flavor ban individuals must not want to quit vaping or stop using their flavored product for the next 90 days.
Exclusion criteria
* Individuals with health conditions and therapies that may affect immune responses and levels of inflammatory markers, including allergic rhinitis, aspirin/NSAID therapy, asthma, immunodeficiency (HIV or other), Guillain-Barre Syndrome, COPD, or fever/respiratory illness within 30 days prior to entry into study (self-reported). * Pregnant or nursing female participants (self-reported on telephone screener, pregnancy test on Visit#1) * Unable to communicate in English. * Unable or unwilling to follow protocol requirements. * Self-report having active, untreated medical/psychiatric conditions. * History of serious side effects from nicotine or from any nicotine replacement therapies. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements * Vulnerable populations, such as cognitively impaired adults, individuals who are not yet adults, pregnant women, and prisoners. * Any condition which in the Investigator's opinion deems the participant an unsuitable candidate to receive study drug. * After receiving information about the NYS flavor ban, participants who report that they are thinking about quitting or stop using their flavor within the next 90 days.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Risk biomarkers of inflammation and oxidative stress as measured by ELISA | Up to 90 days | Oxidative stress and inflammation in plasma using ELISA . A quantitative measure of expression (units:pg/mg) will be produced. |
| Respiratory tract inflammation activity | Up to 90 days | Exhaled Nitric Oxide (FeNo)l be measured in participants' breath using a FDA cleared monitor NIOX VERO (Aerocrine) according to ATS guidelines. FeNO has been used to monitor airway inflammation to account for persistent and/or high allergen exposure as a factor associated with higher levels of FeNO |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Amount of recent flavored product use | UP to 90 days | Assessed using the PhenX Toolkit which tracks tobacco use and asks subjects to retrospectively estimate product use, |
| Flavor Preference questionnaire | Up to 90 days | Personal flavor questionnaire to determine flavor preference when using ENDS. |
| Frequency of flavored product use | Up to 90 days | Questions from Wave 1 Adult PATH Survey to measure use and regularity of use flavored products |
