# Effect of Flavor and Nicotine Concentration on Smoker Perceptions of JUUL

## What is the purpose of the study?

This study will examine how nicotine concentration and flavor of e-liquids affects mood and responses to electronic cigarettes. The Food and Drug Administration {FDA) regulates tobacco products including electronic cigarettes, and can require product standards that may reduce harm from tobacco products, such as having rules about how much nicotine or which flavors are available to decrease youth uptake.

The study looks at differences across four nicotine/flavor combinations. The measures that we examine will evaluate how using the different nicotine/flavor combinations in an electronic cigarette affects mood and responses to the product, such as satisfaction or taste.

The electronic cigarettes and pods used in this study are JUUL brand that you can buy at the store. They include 3% and 5% nicotine salt weight by volume and Menthol and Virginia Tobacco flavors.

## How often are the clinic visits?

We expect that you will be in this research study for two to three weeks. During this time you will attend one screening session and five visits that will last approximately one hour each at the Delaware Clinic Research Unit on the University of Minnesota Campus. Visits will be at least 48 hours apart.

## What will I be doing in the study?

You will be asked to attend five lab sessions: one where you will use your own cigarette and four where you will sample an electronic cigarette. You will not be able to smoke any cigarettes or other combustible products (e.g. cigars, marijuana) prior to each visit. During the visits, you will complete questionnaires asking you about your mood and your response to the product. You will also have a breath test for carbon monoxide and vital signs will be taken. We will collect one urine sample from you.

## Will I be compensated?

If you agree to take part in this research study, you will be paid $20 for the screening visit,$20 for each of the five lab visits, plus $100 for completing the study and following study procedures, for a total of$220 possible.
