- Brief Summary
While conventional cigarette use continues to decline among youth and young adults, e-cigarette (EC) use is on the rise. Specifically, the investigators will conduct a randomized control trial (RCT) where young adults are randomized to one of two conditions: 1) a regulated ad environment, with high impact EC ad features removed or 2) an unregulated ad environment, with high impact EC ad features left intact. Participants will view EC ads embedded in an online magazine 24 times over the course of 6 months. EC experimentation and sustained use will be the primary outcome of interest.
- Detailed Description
While conventional cigarette use continues to decline among youth and young adults, e-cigarette (EC) use is on the rise. The use of ECs during young adulthood, particularly 18 years of age, is especially alarming because it is not only a critical period in development but also a time when tobacco use is established. Additionally, the tobacco industry targets individuals of this age with the hope that they will one day progress to using combustible cigarettes. Advertising may be one of the reasons leading young people to use ECs, and the Food and Drug Administration (FDA) now has the authority to regulate EC advertisement features. The goal of the proposed study is to determine which EC ad features most strongly influence young adults' attitudes, susceptibility, and intentions to use ECs, and determine if the restriction of these ad features influences EC attitudes, experimentation, and sustained use. The investigators will experimentally estimate the causal effect of restricting high impact EC ad features on tobacco use behavior. Specifically, the investigators will conduct a randomized control trial (RCT) where young adults are randomized to one of two conditions: 1) a regulated ad environment, with high impact EC ad features removed or 2) an unregulated ad environment, with high impact EC ad features left intact. Participants will view EC ads embedded in an online magazine 24 times over the course of 6 months. EC experimentation and sustained use will be the primary outcome of interest. We will also examine how sensation seeking, impulsivity, and sleep health impact EC use. Findings from this study will provide public health officials important and urgently needed information as to what advertising features are contributing to the sharp rise in the use of ECs among young adults, and if restrictions reduce the use of ECs among young adults.

- Primary Outcome Measures
Name Time Method Perceived severity of using E-Cigarettes 6 months Perceived severity of using ECs will be assessed by participants' perceived significance, severity, and seriousness of health threats from EC use. The measure is as follows:
Please rate the following statements on a scale from 1 (strongly disagree) to 5 (strongly agree).
I believe that the health threat of using e-cigarettes is severe. I believe that the health threat of using e-cigarettes is serious. I believe that the health threat of using e-cigarettes is significant.Tobacco Use 6 months Use of any tobacco products
Motivation to Avoid E-Cigarettes 6 Months Motivation to avoid ECs including importance, confidence, and readiness to avoid ECs will be collected to assess for changes in motivations. The measure is as follows:
How important is it to avoid e-cigarettes in the future? 0=Not important at all 10=Very important How confident are in avoiding e-cigarettes in the future? 0=Not confident at all 10=Very confident How ready are you to avoid e-cigarettes in the future? 0=Not ready at all 10=Very ready How committed are you to avoid e-cigarettes in the future? 0=Not committed at all 10=Very committedBehavioral Intentions Behavioral Intentions 6 months Behavioral intentions will be evaluated using questions "How interested are you in trying ECs?," "How willing are you to try ECs?," 'How willing would you be to purchase an EC?," and "How willing would you be to try an EC if a friend offered you one?".
Salivary Cotinine 6 months Bioochemical confirmation of tobacco non-use will be conducted with salivary cotinine (\~3 day nicotine biomarker).
