Trauma-induced addiction is increasingly understood not as a failure of willpower, but as an adaptive response to chronic dysregulation within the nervous system. Through the lens of Polyvagal Theory, this presentation reframes substance use as a survival strategy rooted in the autonomic nervous system’s attempt to manage overwhelming internal states. Developed by Stephen Porges, Polyvagal Theory offers a neurophysiological framework for understanding how individuals shift between states of safety (ventral vagal), mobilization (sympathetic), and shutdown (dorsal vagal) in response to perceived threat. For individuals with significant trauma histories, these states can become rigid, extreme, and chronically activated, creating the internal conditions that drive compulsive substance use. This presentation explores how trauma disrupts the nervous system’s capacity for regulation, leaving individuals oscillating between hyperarousal (anxiety, agitation, panic) and hypoarousal (numbness, dissociation, collapse). Substances are then utilized as tools of regulation—stimulants to counteract shutdown, depressants to dampen overwhelming activation, and dissociative substances to escape intolerable emotional pain. From this perspective, addiction is not pathology but adaptation: an attempt to achieve neuroception of safety in a system that has learned the world is unsafe.

Participants will gain a deeper understanding of how early attachment disruptions, chronic stress, and adverse experiences shape autonomic patterning and influence behavioral health outcomes. The concept of neuroception—how the nervous system subconsciously detects safety or threat—will be examined in the context of treatment engagement, relapse, and resistance. When clients are stuck in defensive states, traditional cognitive or insight-based interventions often fail, as the nervous system is not primed for connection or change. This underscores the necessity of bottom-up, somatically informed approaches that prioritize regulation before cognition.

The presentation will also highlight clinical applications for integrating a Polyvagal-informed approach into substance use disorder treatment. Emphasis will be placed on creating environments of safety, co-regulation within the therapeutic relationship, and interventions that support nervous system flexibility. Strategies may include breathwork, grounding, rhythm, relational attunement, and body-based awareness practices. Additionally, the role of clinicians’ own nervous systems will be addressed, recognizing that provider regulation directly impacts client outcomes through processes of co-regulation.

By shifting the narrative from “What is wrong with this person?” to “What happened to this nervous system?”, providers can reduce stigma, enhance empathy, and improve engagement with individuals struggling with addiction. This framework aligns with trauma-informed care principles and supports a more compassionate, effective approach to treatment. Ultimately, understanding addiction through a Polyvagal lens allows clinicians to target the underlying dysregulation driving substance use, fostering more sustainable pathways to recovery grounded in safety, connection, and resilience.
