Purpose: An increasing non-drinker population is developing, but much research focusses on alcohol misuse, rather than the experiences of those who abstain or consume little alcohol, particularly within student populations. This student co-constructed qualitative research aimed to understand alcohol abstainer and light drinking students' university experiences and perceptions of university alcohol cultures, given recent trends in alcohol drinking behaviour. Design/methodology/approach: Ten UK undergraduate students (six males, four females; 21-26 years), five alcohol abstainers and five light alcohol drinkers (AUDIT-C), participated in semi-structured focus group interviews. Findings: Thematic analysis of transcripts identified participants' negative experiences of pre-university social pressures in navigating no or low alcohol drinking identities, which impacted university expectations. Participants perceived alcohol drinking cultures as remaining prevalent on university campuses and possibly used for profit and recruitment. Alcohol dominant university-sanctioned social events, alongside limited other provisions, impacted initial university transitions and belonging. However, students reported co-existing realities between such cultures and simultaneous peer acceptance of their no or low drinking status, finding similar others and long-term friendships not impacted. Due to this, student participants called for universities to take urgent action in changing pervasive university alcohol cultures, which they felt no longer aligned with changing student behaviours and perceptions. Originality/value: Guided by findings, we provide important implications for prevention work and future research, including the importance of social context interventions. We also highlight the value of student co-creation and external partnerships within such work.
