El consumo episódico excesivo de alcohol representa la problemática adictiva de mayor prevalencia en Argentina para el rango etario de 18 a 24 años, a la vez que se impone como la primera causa de mortalidad en los menores de 30 años. Este trabajo se desarrolló en el marco de la Cátedra I de Salud Pública y Mental, cuyo titular es Martín de Lellis. Los objetivos específicos se orientaron a caracterizar la magnitud y frecuencia del consumo de sustancias en jóvenes de 18 a 24 años durante los períodos de Aislamiento Social Preventivo y Obligatorio y Distanciamiento Social Preventivo y Obligatorio; describir la intensidad y las modalidades del consumo de alcohol en la población de estudio en esa etapa. El supuesto es que el consumo de bebidas alcohólicas en jóvenes pueden tener características distintas a las observadas en períodos previos. Se realizó un estudio descriptivo de corte transversal. Empleándose un instrumento creado Ad-hoc en forma de formulario online. El muestreo fue intencional, no probabilístico, empleando la estrategia bola de nieve. Los resultados arrojaron que un 33,4% de los jóvenes disminuyeron significativamente su consumo de alcohol, 13,2% reportó haber aumentado ligeramente y un 5,6% aseveró haber aumentado significativamente.
