Flavors and E-cigarette Effects in Adolescent Smokers- STUDY 2

April 30, 2020 updated by: Yale University
This study is to examine if inhaled doses of an e-cigarette flavor, alone and in combination with menthol, changes the appeal of e-cigarettes containing low and high doses of nicotine. The hypothesis is that menthol and the other experimental flavor will interact with nicotine dose to improve taste and liking for e-cigarettes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: Baseline (+10 minutes) to end of lab session (+40 minutes)
The Drug Effects Questionnaire (Soria et al) will be used to ask about liking and wanting during the lab session
Baseline (+10 minutes) to end of lab session (+40 minutes)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
