Can Light Therapy Help People Overcome Opioid Addiction?
Early clinical evidence suggests yes. This case series from 42 consecutive patients with opioid use disorder found that unilateral transcranial photobiomodulation, applied as an adjunct to standard treatment, showed positive responses in the majority of patients, with some showing remarkable improvement.
Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation (PBM), uses specific wavelengths of red and near-infrared light to promote healing and reduce inflammation.
Opioid use disorders cause enormous suffering to individuals, families, and communities. Available treatments are limited, and many patients continue to struggle even with medication-assisted therapy and counseling. This paper presents a novel approach: shining near-infrared light on one side of the brain to help reduce cravings and improve outcomes.
What the Research Shows
The author, Dr. Fredric Schiffer, a neuropsychologist, presents a retrospective overview and four detailed case reports from 42 consecutive patients with opioid use disorders. The treatment involved unilateral transcranial photobiomodulation (UtPBM) using near-infrared light, applied to the brain hemisphere with the more positive emotional state. This was used alongside the patients’ usual psychotherapy and medications. Two cases showed very positive responses, one showed a moderately positive response, and one was non-responsive. The overall pattern across the 42 patients suggested that the majority experienced some degree of benefit from the therapy.
Dr. Kumar’s Take
The opioid crisis is one of the most devastating health problems of our time. Any new tool that can help, even as a supplement to existing treatments, is worth investigating. What is fascinating about this approach is the concept of targeting a specific brain hemisphere based on the patient’s emotional profile. The idea that PBM can modulate brain function in ways that reduce cravings is biologically plausible given what we know about how light affects mitochondrial function and neurotransmitter activity. This is early-stage evidence, not a proven cure, but the results are encouraging enough to warrant further study.
Practical Takeaways
- Transcranial PBM showed positive responses in the majority of patients with opioid use disorders in this clinical series.
- The therapy was used as an adjunct to standard treatment, not as a standalone intervention.
- UtPBM is painless, noninvasive, and easily administered in a clinical setting.
- More research is needed, but these early results suggest PBM could become a valuable addition to addiction treatment.
FAQs
How does light therapy reduce opioid cravings?
The proposed mechanism involves improving prefrontal cortex function through increased mitochondrial energy production. The prefrontal cortex is critical for impulse control and decision-making. By boosting its function, PBM may help patients better manage cravings and make healthier choices.
Is this a replacement for medication-assisted treatment?
No. In this case series, PBM was used alongside standard medications and psychotherapy. It is intended as an adjunct tool that may enhance the effectiveness of existing treatments, not replace them.
Was this a controlled trial?
No. This was a retrospective clinical case series, which is a lower level of evidence than a randomized controlled trial. The results are promising but preliminary. Larger, controlled studies are needed to establish the effectiveness of PBM for opioid use disorders.
Bottom Line
Transcranial Red light therapy shows early promise as an adjunct therapy for opioid use disorders. This clinical case series found positive responses in the majority of 42 patients treated, though the evidence is preliminary. For a crisis with limited treatment options, PBM represents a novel, noninvasive approach that warrants further investigation.
