Smoking, vaping and drinking: A qualitative analysis of Aotearoa New Zealand young adults who tried e-cigarettes to stop smoking tobacco

Background and aimSocial practices such as smoking-drinking co-use often go 'hand-in-hand', linked by the coordination of materials, skills and meanings. However, the experience of using e-cigarettes while drinking among people who smoke (and drink) remains underexplored. We used social practice theory to show how smoking, vaping and drinking intersect and to explain how vaping created two new social practices among people who tried e-cigarettes to stop smoking: 'vaping-drinking' co-use and 'smoking-vaping-drinking' poly-use.MethodsWe conducted five in-depth interviews over 18-24 weeks during 2018-19, with each of nine Aotearoa New Zealand young adults aged 20-29 years. Participants smoked daily, did not regularly use e-cigarettes at entry and wished to try vaping to stop smoking. We analysed participants' reports of smoking or vaping while drinking using thematic analysis.ResultsIndividual participants reported both co-use and poly-use occasions throughout the study. Vaping-drinking co-use arose from practice 'replacement' processes, where vaping fully substituted smoking. Smoking-vaping-drinking poly-use arose from 'adjacency' processes where vaping complemented smoking. Participants used both processes flexibly over time, which required new skills in material, temporal, pleasure and social coordination to try to recreate valued meanings of comfort, security and communality associated with well-established smoking-drinking practices. Unsuccessful coordination attempts maintained smoking-drinking co-use.ConclusionAmong Aotearoa New Zealand young adult smokers who want to use vaping to stop smoking, drinking occasions may help to maintain existing smoking-drinking practices and facilitate the development of vaping-drinking co-use and smoking-vaping-drinking poly-use practices, potentially prolonging individuals' exposure to smoking.
