Health Warning Labels

ClinConnect Summary

This clinical trial is studying the effects of special health warning labels on electronic cigarettes, also known as ENDS devices, to see how they influence young adults' feelings about using these products. Researchers have created pictorial warning labels that will be tested in a lab setting. They want to understand how these labels affect things like users' satisfaction, their perception of harm, their dependence on nicotine, and their intentions to quit using ENDS. The study also looks at actual nicotine levels in the participants' bodies and how they use the devices.

To participate, you must be a generally healthy adult aged 21 to 35 who has used ENDS in the last month but is willing to stop using them for 12 hours before each lab session. You cannot be a regular smoker or user of other tobacco products, and certain health conditions or recent illnesses may disqualify you. If you decide to join the study, you will attend lab sessions where your responses to the warning labels will be measured and analyzed. This research aims to provide valuable insights into how effective these health warnings can be in reducing electronic cigarette use among young adults.
