[Medico-biological and psychopathologic aspects of substance dependence]. / Aspetti medico-biologici e psicopatologici delle tossicodipendenze.

The paper examines the phenomenon of drug addiction from a bio-socio-pathological point of view. Neurophysiological advances in the field of drug addiction reveal the correlations between biology and behaviour, thus allowing the creation of numerous synergic strategies at different levels of intervention.
