. Explain biopsychosocial issues associated with substance abuse in families.
BioPsycho-social systems are concrete entities or groups whose members act in relation to each other, such as families, religious organizations, and political parties . Social processes in addiction are investigated by examining social categories such as networks, groups, organizations and subcultures that alone cannot be explained by neurobiology.

The larger societal structure either restricts or enhances interactions between agents in a social system . Such actions require explanations at both the systemic and individual levels.
