The Effect of Graphic health Warning Labels Placed on the ENDS Device on Young adult Users’ Experience, Exposure and Intention to Use: a Pilot Study.

Introduction:
This text discusses a pilot study that examines the effect of placing graphic health warning labels (GhWLs) on electronic nicotine delivery system (ENDS) devices on users' experiences, puffing patterns, harm perception, nicotine exposure, and intention to quit or use in the future. The study compares the experiences of JUUL users when using a device with a GhWL to when using a device without a GhWL.

Key Points:

* The study found that using JUUL with a GhWL on the device was significantly associated with reduced positive experiences such as pleasure, product liking, and user satisfaction.
* Participants were less interested in using the same product again and less likely to use the product if it was the only one available in the market after exposure to the GhWL.
* Trends toward reduced puffing behavior and nicotine boost were also noted during the GhWL sessions.
* The study used a within-subject repeated measure design, recruiting current JUUL users without chronic health problems or regular use of prescription medications.
* Participants attended two lab sessions, one without a GhWL and one with a GhWL, and were asked to abstain from ENDS and other tobacco/nicotine use for at least 12 hours prior to study activities.
* Subjective measures, JUUL puff topography, and plasma nicotine boost were assessed during each session.
* The study found that the GhWL on the ENDS device was effective in reducing users' positive experiences, motivation to use in the future, and trends toward reduced puffing behavior and nicotine boost.

Main Message:
The study suggests that placing GhWLs on ENDS devices may be an effective and promising strategy to reduce ENDS use among young people. The results support the need for further research in this area and highlight the potential of this approach to reduce ENDS appeal and use for young people.
