The Moment Study: Mixed Method Ecigarette Study (Moment)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The universe of tobacco products is expanding, with new noncombustible products gaining popularity even as the reduction in prevalence of cigarette smoking slows or stalls. E-cigarettes, or Electronic Nicotine Delivery Systems (ENDS), are the most prevalent of these emerging noncombustible products. With sales increasing rapidly and more efficient pulmonary delivery devices under development, ENDS are likely to play an increasing role in the future tobacco market. Little is known about the cognitions and behaviors leading to or sustaining ENDS use. Smokers may use ENDS to subvert smoking restrictions, to reduce perceived smoking harms, or for smoking cessation. Evidence about ENDS use is emerging from national surveillance and laboratory research, but the majority of information on ENDS is limited to retrospective surveys and convenience samples of White male ENDS users. The investigators research suggests Black smokers are less likely than White smokers to try and be current ENDS users, perhaps due to a greater degree of perceived harm associated with ENDS, a preference for menthol, or cultural norms. Thus, it is timely and critical to study how all smokers, including Blacks and menthol smokers, experience and initiate ENDS use employing valid, innovative research methods.

Accepts Healthy Volunteers:
In total, our goal is to enroll 150 individuals, with 120 participants completing the protocol. For the main arm of the study, we will recruit a racially and ethnically diverse sample of 140 daily smokers (or 100 study completers), with the goal of recruiting at least 50% non-Hispanic black participants. For the second study arm, we will enroll an additional 30 participants, with the goal of 20 individuals completing the protocol. There are no race/ethnicity recruitment goals associated with the second arm. In total, the main study arm will consist of 100 daily smokers who do not intend to quit smoking in the next 30 days, while the second arm will include 20 daily smokers who do intend to quit smoking in the next 30 days.
