The Weight of Trauma
Post-traumatic stress disorder affects approximately 9% of Canadians at some point in their lifetime. For veterans, first responders, and survivors of abuse, accidents, or catastrophic loss, PTSD can become a defining feature of daily life — intrusive memories, hypervigilance, emotional numbness, and a sense of permanent disconnection from safety.
Traditional treatments — SSRIs, CBT, EMDR — help many people. But for a significant subset, trauma runs deeper than existing tools can reach. That’s where ketamine-assisted psychotherapy has begun to generate meaningful clinical interest.
How Ketamine May Help Trauma
Ketamine’s mechanism isn’t fully understood, but researchers believe it works in part by temporarily quieting the fear-memory system. In animal studies, ketamine has been shown to disrupt the reconsolidation of fear memories, essentially creating a window during which traumatic associations can be re-processed with less emotional charge.
In a clinical setting, this means clients may be able to approach traumatic material with more psychological distance, processing experiences that would otherwise feel too overwhelming to revisit. Combined with skilled trauma-focused psychotherapy during and after the session, this can produce meaningful relief.
What Does the Research Say?
The evidence base for ketamine in PTSD is still evolving. Current CANMAT and international guidelines recognize ketamine for treatment-resistant depression — and PTSD frequently co-occurs with depression. Some clinical settings, particularly those serving veterans, have incorporated ketamine protocols with encouraging outcomes.
It is important to be honest: ketamine is not currently a first-line, guideline-recommended PTSD treatment on its own. What it can be, in the right hands, is a powerful adjunct to evidence-based trauma therapy. Our clinical team in Ottawa assesses each case individually and is transparent about what current evidence does and doesn’t support.
Our Approach to Trauma-Informed KAP
FlowState Therapy in Ottawa — the clinical team behind ketamineottawa.ca — has specific experience working with veterans, first responders, and others navigating complex trauma. Our approach is rooted in safety, consent, and trauma-informed care principles. We don’t rush the process.
Ketamine is administered intramuscularly (IM) in our clinic — a method associated with reliable dosing and a smooth, manageable experience. Sessions are always accompanied by a therapist, and integration is built into the protocol from day one.
Is It Covered for Veterans?
Veterans Affairs Canada (VAC) may provide funding for mental health treatment — including psychotherapy services — for eligible veterans with service-related conditions. We strongly encourage veterans to explore what they may be entitled to. Our team can support you in navigating this process.
