Exposure to JUUL use: cue reactivity effects in young adult current and former smokers.

Introduction:
This text is a summary of a scientific study examining the cue salience of JUUL, a popular type of electronic nicotine delivery system (ENDS), in young adult smokers. The study aims to determine whether observation of JUUL use elicits smoking and vaping urge in smokers and former smokers. The key points and main message of the study are summarized below.

Key Points:

* The study used a within-subjects design, with each participant being exposed to both a control cue (water bottle) and an active cue (JUUL) in a controlled laboratory setting.
* The sample consisted of 62 current smokers and 20 former smokers.
* The cue phase consisted of a 5-minute task period where the participant and a confederate engaged in a conversation, followed by a rest period, and then the confederate used the JUUL device during the second task period.
* The study measured changes in smoking urge and desire for cigarettes, mod/vape pens, and JUUL using the Brief questionnaire of Smoking Urges (BqSU) and visual analogue scale (VaS) items.
* The results showed that exposure to the JUUL cue significantly increased participants' ratings of smoking urge and desire for cigarettes, mod/vape pens, and JUUL in current smokers.
* Former smokers also showed a small, transient increase in desire for cigarettes and JUUL after exposure to the JUUL cue.
* The study concludes that observation of JUUL use may act as a smoking cue and elicit smoking urge and behavior in young adult smokers, and may also increase the risk of relapse in former smokers.

Main Message:
The main message of the study is that the widespread use of JUUL and other ENDS products may impact public health by inducing desire to smoke and smoking behavior in young adult smokers and by increasing the risk of relapse in former smokers. The study highlights the importance of considering the observers' experiences when evaluating the public health impact of the escalating use of ENDS. The cue salience of JUUL may inform regulation of these products, limits to marketing exposures, and restrictions on use to avoid potential renormalization and elicitation of smoking behaviors.
