Brief Summary:
The goal of this clinical trial is to learn if low nicotine eliquids work to reduce exposure to nicotine in addicted ecig users without increasing consumption of other harmful constituents
The main questions it aims to answer are
Does switching to lower nicotine eliquids change the vaping behavior of addicted ecig users
Does switching to lower nicotine eliquids reduce the amount of nicotine consumed Researchers will compare ecig users who switch from a higher to lower nicotine eliquid to a control group that does not switch
Participants will
Complete history of tobacco use and nicotine addiction questionnaires
Switch from higher to lower nicotine product or control for 15 days
Complete daily questionnaires to report craving mood and nicotine withdraw
For one full day under each nicotine condition participants will
record puffing behavior using a topography monitor
wear a sensorized shirt that measures the depth and duration of inhalation and
collect a saliva sample at the end of each day

Detailed Description:
This project will investigate whether and how e-cig users compensate puff topography lung inhalation and cumulative consumption in response to reduced nicotine eliquid The project is conducted in the natural environment to objectively measure if users adapt their behavior to maintain their desired level of nicotine
The project employs a novel behavior-based exposure model that leverages the unique abilities of the investigative team to objectively capture real world behavior The study employs a novel wPUM monitor to record puffing topography and a sensorized shirt to record respiratory parameters for every vaping session
This study is conducted in the natural environment over 17 days We will recruit N80 current established adult ecig users currently using eliquids with nicotine strengths greater than or equal to 5 with no intention to quit e-cig use and no use of combustible or other tobacco products Participants will be randomized by age gender usual brand nicotine strength and nicotine dependence score into a control arm non-switching and a test arm switching All participants will be baselined with 5 Juul ecigs and Juul pods containing Virginia Tobacco at 5 nicotine strength The test arm will be switched to a 3 Juul pods containing Virginia Tobacco at 3 nicotine strength eliquid while the control arm will continue to use 5 nicotine strength
Participants will use the RIT wPUM monitor with a Juul ecig and a wearable sensorized garment to record their e-cigarette use topography and inhalation behavior ad-lib in their natural environment at the baseline and intervention conditions for one day each Biosamples for nicotine exposure in saliva NNAL in urine and CO will be collected along with questionnaires to assess product use compliance and psychosocial outcomes such as craving withdrawal and positivenegative emotional state
Aim 1 Quantify changes in Total Particulate Matter TPM exposure among e-cig users adapting to low nicotine eliquids through compensatory changes in puffing inhalation and consumption behavior
TPM exposure will be quantified in the natural environment by recording the topography puff flow rate duration volume of every puff taken along with respiratory behavior inhalationexhalation volume and time and breath hold This novel outcome measure of exposure is used as a proxy to indicate the impact of behavior on increasing harm potential We will test hypothesis H1 that upon changing to a lower nicotine eliquid users will adapt their behavior ie increase breath hold adjust puff flow rate etc and in doing so will increase their TPM exposure
Aim 2 Quantify changes in salivary among e-cig users adapting to low nicotine eliquids
Salivary cotinine will be measured as a proxy to indicate efficacy of compensatory behavior A Generalized Linear Mixed-Effects Model GLME analysis will be used to investigate how the ability of users to compensate for low nicotine e-liquids is affected by the presence of random effects including sex age nicotine dependence score usual brand nicotine strength and subjective effects including craving withdrawal symptoms and positivenegative emotional state We will test the hypothesis H2 that users are able to maintain desired nicotine levels while using a lower nicotine eliquid
Relationship to Tobacco Regulation Knowledge gained will support development of effective tobacco product regulations by informing three research questions of regulatory interest a Will limiting the eliquid nicotine concentration reduce harm at the population level b Is there evidence of compensatory behavior exhibited by e-cig users in response to reduced nicotine concentration and c Can we conduct meaningful behavior-based e-cig use risk assessment at the individual level
