When working with individuals affected by substance use, one pattern shows up again and again: a history of trauma. Whether we’re talking about childhood abuse, neglect, domestic violence, homelessness, or other deeply distressing events, trauma is often at the root of problematic drinking or drug use. Yet, all too often, trauma remains unspoken or misunderstood—especially in frontline services under pressure to manage risk, reduce harm, and achieve outcomes.
At Reflect Training, we believe that understanding the relationship between trauma and substance use is essential for anyone working in health, housing, social care, or addiction services. This blog explores how trauma shapes substance use, what trauma-informed care really means, and why staff training is critical for delivering compassionate, effective support.
What Is Trauma?
Trauma is not just what happens to someone—it’s also how they experience it.
According to the Substance Abuse and Mental Health Services Administration (SAMHSA), trauma is the lasting emotional response that often results from living through a distressing event. This could include one-off incidents like accidents or assaults, or long-term, repeated experiences like abuse, discrimination, or neglect.
There are many types of trauma, including:
- Acute trauma (a single event)
- Chronic trauma (repeated exposure, such as domestic abuse or bullying)
- Complex trauma (exposure to multiple traumatic events over time, especially in childhood)
- Intergenerational trauma (historical or cultural trauma passed down through generations)
Trauma affects the brain, the nervous system, relationships, and our ability to feel safe. It can lead to anxiety, depression, emotional dysregulation, and a deep sense of shame or worthlessness—all of which increase vulnerability to substance misuse.
Why Trauma and Substance Use Are Closely Linked
Many people who use drugs or alcohol problematically are not trying to “get high”—they’re trying to feel better. They’re using substances as a way to cope, escape, or survive. In this context, addiction makes sense.
Common reasons people with trauma histories may use substances include:
- To numb emotional pain (e.g. dissociation or depression)
- To manage symptoms of PTSD (e.g. flashbacks or hypervigilance)
- To sleep or feel safe enough to rest
- To regulate emotions (e.g. anger, fear, shame)
- To fit in or feel less alone
- To feel in control of something
This is often referred to as self-medication. While it may work temporarily, over time, substance use can reinforce trauma symptoms, increase shame, and lead to dependency or health problems. It becomes a cycle that’s hard to break—especially without support that understands the trauma underneath.
The Impact of Childhood Trauma (Adverse Childhood Experiences)
Research shows that Adverse Childhood Experiences (ACEs) have a powerful impact on later substance use. ACEs include experiences like:
- Physical, emotional, or sexual abuse
- Domestic violence
- Parental substance use or mental illness
- Divorce or loss of a parent
- Neglect or emotional abandonment
The original ACE study found that people with 4 or more ACEs are:
- 2–4 times more likely to use drugs or alcohol problematically
- 7 times more likely to become alcohol dependent
- 10 times more likely to inject drugs
The brain adapts to early trauma by staying in a state of “survival mode,” which can last into adulthood. Without trauma-informed support, many people repeat harmful patterns—especially if they’ve been let down or stigmatised by services in the past.
What Is Trauma-Informed Care—and Why Does It Matter?
Trauma-informed care (TIC) is not a therapy—it’s an approach. It means shifting from “What’s wrong with you?” to “What happened to you?”
A trauma-informed approach recognises the widespread impact of trauma and integrates this understanding into every aspect of support. This includes:
- Creating safety (emotional, physical, and psychological)
- Building trust and transparency
- Supporting choice and empowerment
- Recognising triggers and avoiding re-traumatisation
- Promoting collaboration and respect
In substance use services, trauma-informed care involves:
- Understanding that relapse or disengagement may be trauma responses, not “non-compliance”
- Avoiding confrontational or punitive approaches
- Being aware of how our own tone, body language, or rules might feel unsafe to someone with trauma
- Making room for people’s stories, not just their risk assessments
Without a trauma-informed lens, we risk misinterpreting behaviour, reinforcing shame, and driving people further away from support.
Real-World Examples: When Trauma Goes Unseen
At Reflect Training, we’ve worked with countless frontline teams who share stories like these:
- A woman with alcohol dependency is labelled “non-engaging” because she avoids group therapy. Later it’s revealed she was sexually abused in childhood and doesn’t feel safe around men.
- A man in temporary housing keeps relapsing. Staff assume he is not “motivated.” In reality, he’s experiencing flashbacks every night and drinks to sleep.
- A young person in supported accommodation is aggressive towards staff. But he grew up in care and associates authority figures with danger.
In each case, understanding the trauma behind the behaviour could lead to very different—and more effective—responses.
Why Trauma-Informed Training Is Essential for Staff
Frontline workers are often expected to manage high-risk situations without the training, time, or support they need to do it safely. When staff lack a trauma-informed understanding, they may:
- Misread behaviours as manipulative or resistant
- Escalate conflict unintentionally
- Burn out from constant stress and emotional exposure
- Feel helpless when standard interventions don’t work
Trauma-informed training gives staff the tools to:
- Recognise trauma responses in behaviour and communication
- Respond with empathy and clear boundaries
- Create safer, more inclusive environments
- Reduce re-traumatisation and promote engagement
- Reflect on their own triggers and stress responses
It also helps organisations shift culture—from reactive to reflective, from punitive to supportive.

Final Thoughts
Trauma and substance use are deeply connected. For many people, using drugs or alcohol is a way to survive pain that has never been recognised or supported. When we understand this, we stop blaming, shaming, or labelling—and start helping people to heal.
Trauma-informed training isn’t just about learning new skills. It’s about seeing things differently. If you’re ready to make that shift in your organisation, Reflect Training is here to support you every step of the way.
