June is Post-traumatic stress disorder awareness month. PTSD is a disorder that is commonly associated with war veterans. But, as seen in the infographic below, it can also occur in people who have experienced the sudden death of a loved one, a car accident, or a range of other traumatic events.
Understanding the Trauma-Addiction Connection
PTSD and substance use disorders can often occur together. Similar events that trigger post-traumatic stress may also drive individuals to cope using chemical substances. This co-occurrence, known as a dual diagnosis or co-occurring disorders, presents unique treatment challenges that require integrated care approaches addressing both conditions simultaneously.
When someone experiences trauma, their brain’s stress response system can become dysregulated, leading to hypervigilance, intrusive memories, nightmares, and emotional numbness. Substances may initially provide temporary relief from these distressing symptoms, creating a cycle where the person uses drugs or alcohol to self-medicate their PTSD symptoms. Unfortunately, this coping mechanism ultimately worsens both conditions over time.
The Prevalence of Co-Occurring PTSD and Addiction
One study found a 41% prevalence of lifetime post-traumatic stress disorder among individuals who used heroin. The same study found that individuals with PTSD were more likely to experiment and develop dependencies on a wider range of substances. They also had poorer physical and mental health, but were more likely to be in treatment.
This higher treatment-seeking rate among those with PTSD may reflect the severe impairment caused by managing both conditions. It also suggests that the distress from untreated trauma can motivate people to seek help, even when addiction alone might not have driven them to treatment.
Implications for Treatment Programs
This means that treatment centers have a much higher than average proportion of individuals with PTSD, which speaks to the importance of various types of therapy. Evidence-based approaches like Eye Movement Desensitization and Reprocessing (EMDR), Cognitive Processing Therapy (CPT), and trauma-focused Cognitive Behavioral Therapy (CBT) have shown significant success in treating PTSD alongside addiction.
Effective treatment must address the underlying trauma while supporting recovery from substance use. Integrated treatment models that tackle both conditions concurrently produce better outcomes than treating each disorder separately.
