This study is looking at how well oral cannabis solutions can help people with long-lasting back or neck pain. Researchers want to see if solutions containing THC/CBD or just THC can reduce pain and help people lower their use of opioid medications. You might be able to join if you are between 21 and 84 years old and have had chronic spine pain for at least three months. The study will measure changes in your pain levels using a Visual Analog Scale (VAS) and track any changes in your opioid dose over several weeks. The study is currently unclear on its recruitment status and plans to enroll 157 participants.
