Revista Internacional de Investigación en Adicciones (RIIAD) is an initiative of Centros de Integración Juvenil aimed at promoting the dissemination and diffusion of the results of scientific research in the field of drug use, mental health and its care. It is published biannually (twice a year), electronically and in print. In accordance with good practices in scientific publishing, manuscripts received are initially reviewed by an internal review committee; those that are approved are subsequently refereed in a double-blind process by expert adjudicators on the different topics.
