Developing a Vape Shop-Based Smoking Cessation Intervention: A Delphi Study

Providing access to a vape shop-based smoking cessation intervention may simultaneously increase e-cigarette use and increase the effectiveness of e-cigarettes for smoking cessation. The aim of this study was to identify the most important elements of vape shop-based smoking intervention to stakeholders who would be involved in delivering or accessing such an intervention.

We conducted a three-round Delphi study of vape shop staff (n = 40), stop smoking professionals and tobacco control leads (n = 30), and smokers, vapers, and dual users (n = 30) in the United Kingdom in May-August 2021. In each round participants were asked whether they agreed or disagreed with statements related to vape shop-based interventions.

Forty-six of 95 statements reached consensus in round 1, 29 out of 49 in round 2, and 8 out of 20 in round 3. There was support for a vape shop-based intervention across stakeholder groups (96%). There was consensus that the service should comprise both product (98%) and behavioral support (97%), and that quitting vaping should not be a goal of the service (79%). Although there was consensus that there should be some free product provision, there was less consensus as to what this should involve. Views were mostly consistent across stakeholder groups.

There was broad consensus on how to deliver a vape shop-based smoking cessation intervention, providing a strong basis for future intervention development and implementation. Challenges around misuse of the service and misperceptions about vaping would need to be addressed for such an intervention to be feasible and effective.

Many smokers who make a quit attempt using e-cigarettes purchase their vaping products in vape shops. Delivering vape-shop-based smoking cessation interventions could help to maximize the effectiveness of e-cigarettes for quitting smoking. This study used a Delphi approach to identify the most important elements of a vape shop-based intervention among stakeholders. The findings could be used to help develop future interventions.
