The ACE connection

The Adverse Childhood Experiences study showed a direct, dose-response relationship between childhood trauma and adult addiction. Each additional ACE category increases addiction risk. A person with 4+ ACEs has 7 times the risk of alcohol addiction.

How trauma drives use

Substances modulate the hyperactivated stress response that trauma produces. They quiet intrusive memories, reduce hypervigilance, numb emotional pain, and provide temporary escape from a nervous system stuck in survival mode.

Trauma-informed care

Treatment that understands addiction in the context of trauma: asking what happened to you rather than what is wrong with you. Safety first (physical and emotional). Choice and empowerment. Trustworthy relationships. Peer support. Cultural sensitivity.

Treatment approaches

EMDR, CPT, and PE for trauma processing (after initial stabilization). Somatic experiencing for body-held trauma. Trauma-sensitive yoga. Neurofeedback. All delivered alongside addiction treatment, not sequentially.
