The historical view on addiction has continued to evolve over time. The moral model, which is one of the earliest models of addiction posit that addiction results from individual indulging in substance abuse and addiction comes because they are morally weak. However, this model conflicts with the disease model that considers individuals as victims of forces beyond their control. According to Miller (1993) the disease model considers addiction as a single, incurable, all-or-none disorder that is caused by biological abnormalities, thereby limiting the treatment adopted. Miller (1993) proposes a new disease model that takes into consideration the moral and diseases aspect of it.
