[Qualitative study on risk and care practices in nightlife settings with massive presence of people in Buenos Aires City].

The aim of the present study was to investigate care and risk practices carried out in nightlife settings with massive presence of people in the Autonomous City of Buenos Aires. In addition to this, the perceived reasons behind the consumption of psychoactive substances were investigated. For this purpose, 16 young people between 21 and 35 years of age were interviewed. The data was analyzed following the approach proposed in the grounded theory and using the Atlas.Ti program. Practices were studied at individual, group and environmental levels. Among the risk practices, substance availability, excessive intake and substance mixing were frequently mentioned. Regarding care practices, the value of the group was highlighted by keeping together and providing help to its members. Practical implications of these results are discussed, and limitations and future lines of research are presented.
