Substance addiction is one of the important problems threatening society today. Although it causes negative consequences in the person's life, it makes the process more dangerous as the person develops tolerance and desires the substance more. Adolescence is considered a risky period in substance addiction, where psychological, sociocultural and genetic factors play a role, and many factors such as the biological, psychological and environmental conditions of the adolescent determine the development processes of substance addiction. At this point, the family plays a role in the child's social and cognitive development and is seen as an important factor in the process of developing substance addiction. Lack of family functionality can lead to aggression and anti-social behavior disorder, and as a result, delinquency and substance use behaviors may occur in the adolescent. In this study, the role of the family in adolescents' development of substance addiction will be discussed.
