Cannabis-based options for diabetic nerve pain in Veterans

Proof of Concept Trial of Cannabis Derivatives in Neuropathic Pain.

NIH-funded research VA Connecticut Healthcare System · NIH-11310852

This project tests whether cannabis-derived medicines (THC, CBD, or combinations) can help reduce painful diabetic nerve damage in Veterans aged 21 and older.

What this research studies

You would be invited to join a four-arm clinical trial that compares different cannabis-derived treatments (for example THC, CBD, combinations, or placebo) over a set period. The study enrolls adult Veterans with chronic diabetic peripheral neuropathy and tracks pain levels, side effects, mood, adherence, and biological markers. Visits will include regular check-ins, medication dispensing through VA research pharmacies, and safety monitoring. The goal is to weigh relief and risks to see which option might best help Veterans with this type of nerve pain.

Who could benefit from this research

Good fit: Ideal participants are Veterans aged 21 or older who have chronic diabetic peripheral neuropathy and meet the study's medical and safety criteria.

Not a fit: People without diabetic neuropathy, those under 21, pregnant people, or individuals with medical or psychiatric conditions that make cannabinoid use unsafe are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, this work could identify cannabis-based options that relieve diabetic nerve pain with fewer side effects and potentially reduce reliance on opioids for Veterans.

How similar studies have performed: Prior clinical trials of cannabinoids for neuropathic pain have been small and produced mixed results, so clear benefits remain uncertain.
