EMDR for Trauma and Addiction: What You Need to Know

If you've been researching therapy for trauma or addiction, there's a good chance you've come across the term EMDR. Eye Movement Desensitisation and Reprocessing has become one of the most widely recognised and rigorously researched trauma treatments available — and for good reason. For many people, it produces changes that years of talking therapy alone hadn't been able to reach. Here is a clear, honest explanation of what EMDR for trauma actually is, how it works, and what to expect.

What Is EMDR?

EMDR is a structured therapy approach developed in the late 1980s by psychologist Francine Shapiro. It was originally designed for the treatment of PTSD and has since been extensively researched and applied to a wide range of trauma presentations, including complex trauma, childhood abuse, grief, and — increasingly — addiction.

The core idea behind EMDR is that traumatic memories are stored differently from ordinary memories — in a way that preserves the original emotional intensity, sensory details and beliefs associated with them. When something in the present triggers these memories, the person re-experiences them with the same emotional charge as the original event, as if it is happening now rather than in the past. EMDR works to reprocess these memories so that they can be stored in a more ordinary way — acknowledged, but no longer activated.

How Does EMDR Work?

EMDR uses bilateral stimulation — most commonly side-to-side eye movements, though tapping or auditory tones can also be used — while the person holds a traumatic memory in mind. This bilateral stimulation is thought to activate a process similar to what happens during REM sleep, when the brain naturally processes and integrates the day's experiences.

The therapy is structured into eight phases, beginning with thorough preparation and history-taking to ensure the person has sufficient stability and resources before approaching traumatic material. Clients are never thrown into processing before they are ready — building safety and grounding is always the foundation.

As processing proceeds, clients typically find that the emotional intensity of a traumatic memory reduces — sometimes dramatically — and that associated negative beliefs about themselves begin to shift. The memory doesn't disappear. But it loses its charge.

EMDR for Addiction

The application of EMDR to addiction is a growing and clinically compelling area. Research suggests that for many people with addiction, the substance use is closely tied to specific traumatic memories — experiences that activate intense distress which the substance temporarily relieves. By directly reprocessing those memories, EMDR can reduce the emotional charge that was driving the substance use at its root.

EMDR for addiction also addresses the craving states themselves — the images, sensations and beliefs associated with the urge to use — through a specific protocol that works directly with addiction-related material.

Does EMDR Work?

The evidence base for EMDR is extensive. It is recognised as a first-line treatment for PTSD by major health bodies worldwide, including the World Health Organisation and the NHS. Research specifically on complex trauma and EMDR continues to grow, with consistently positive outcomes. It is not a magic wand — it requires preparation, courage, and a therapeutic relationship built on trust. But for the right person, at the right time, it can be genuinely transformative.

Can EMDR Be Done Online?

Yes — and effectively. Online EMDR has been extensively validated since 2020 and produces comparable outcomes to in-person delivery. Bilateral stimulation is easily facilitated through video using specialised tools or simple self-tapping techniques. If you are considering EMDR and are based anywhere in the world, online delivery is a fully viable option.
