Long-term effects

2-4x higher risk of developing addiction. Elevated rates of depression, anxiety, and PTSD. Relationship difficulties in adulthood. Chronic health conditions linked to childhood stress (ACEs). Difficulty trusting and forming secure attachments.

Protective factors

One stable, caring adult. Access to therapy. Age-appropriate explanation of the situation. Maintaining routines and normalcy. Peer support (Alateen). Clear message that the addiction is not their fault.
