The E-Cigarette Study for African American Smokers no longer accepting new participants.


What is the purpose of the study?

The purpose of the study is to determine the pattern of use of electronic cigarettes and changes in biomarkers (or chemicals in the body) associated with the use of electronic cigarettes among African American menthol and nonmenthol smokers. 

How often are clinic visits?

There are 3 visits and one follow-up phone call over the course of 12 weeks. There is a 60 minute visit at the start of the study (baseline visit) and 30 minute visits at weeks 2 and 6. At 12 weeks we will complete a questionnaire over the phone. 

What will I be doing in the study?

At the visits, you will complete assessments that include questions about demographics (for example age, gender, education, and employment), tobacco use, and nicotine dependence, and your smoking status will be confirmed using a carbon monoxide (CO) test. At two of the visits, you will be asked to give about a cup of your urine to be tested for body chemicals associated with use of tobacco. From the beginning of the study up until week 6, you will receive either e-cigarettes that contain nicotine or one that has no nicotine depending on the study group to which you are assigned (determined by flipping of a coin) and you will be allowed to select your preferred flavor (menthol or non-menthol) of electronic cigarettes. 

Will I be compensated?

You will receive $40 for completing the baseline visit, $40 for completing the week 2 visit, $50 for completing the week 6 visit, and $20 for completing the week 12 phone call. If you complete all study visits and the phone call, your total compensation will be $150 over the entire study. You will only receive compensation for the visits you complete. 

What should I do if I'm interested?
