• Research objectivesThis study aims to document young people’s experiences with nitrous oxide consumption and to question the effectiveness of existing measures aimed at curbing this practice.• MethodologyThe study is based on 22 semi-structured individual interviews conducted between 2022 and 2023 with young regular users of nitrous oxide. To better understand this activity, a collection of formal (institutions, associations) and informal (social media, etc.) information was also carried out.• ResultsFollowing a presentation of the epidemiology of nitrous oxide consumption and a definition of the concept of “limit experience”, five main dimensions of the practice are highlighted: the role of peers in the first experimentation, the importance of the consumption setting, the supply of raw materials, the status of nitrous oxide in youth culture, and the desire for a limit experience.• Conceptual and managerial implicationsBy focusing on nitrous oxide consumption as a “limit experience”, this research aims to identify prevention strategies and question the effectiveness of existing measures designed to deter youth engagement in this practice and reduce associated risks.• OriginalityThis research defines nitrous oxide consumption as a “limit experience” and documents this previously under-researched practice, highlighting its significance within youth culture and the public health concerns it raises.
