Summary

This study tests whether inhaling medical cannabis three times a day can safely reduce pain in people with diabetic peripheral neuropathy. 122 adults will receive either a low, medium, or high dose of THC or a placebo using a special inhaler. The main goal is to see if pain scores improve after 15 weeks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Medical cannabis (THC) via Syqe inhaler
What this could lead to
If it works, this could offer a new, inhaled option for managing stubborn nerve pain from diabetes.
What could go wrong
This is a small, early-phase trial. The effect may be modest, and side effects like dizziness or drowsiness are possible. Results may not apply to all patients.
