Increasing numbers of young adults in Australia are choosing to abstain from alcohol. Research demonstrates young adults encounter difficulties when choosing to abstain in settings where alcohol consumption is common or expected. This qualitative study explored the lived experiences of abstainers aged 18–24 years to understand if the acceptance of their non-drinking practices is changing and how they managed their non-drinking practice in social contexts where alcohol consumption is common in Queensland, Australia. Drawing on the theoretical framework of symbolic interactionism, we show how drinking practices are prevalent and powerful, evident through pressure from significant others to drink. Second, we show how young adults enact agency to deal with this pressure and participate as a non-drinker through (a) having a strong sense of being, (b) using an empowered verbal response to deflect pressure and (c) choosing alternative non-alcohol-related activities. The findings offer insight into how young adults wishing to refrain from alcohol may participate openly as abstainers in heterogenous drinking groups.
