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.

Participants of reproductive potential who are sexually active must use highly effective birth control methods. Exclusion Criteria: 1. Evidence of significant uncontrolled concomitant disease that could affect compliance with the protocol at screening or randomization, ability to complete the study, or study assessments. 2. Presence of skin conditions in the affected dermatome at screening or randomization that could interfere with the evaluation of the neuropathic pain condition. 3. Presence of pain not associated with diabetic peripheral neuropathy (DPN) or other neuropathies that may interfere with study assessments. 4. Known history of significant hypersensitivity, intolerance, adverse reaction or allergy to cannabis products, cannabinoids, or acetaminophen/paracetamol. 5. Malignancies in the past 5 years prior to screening, except for cutaneous basal cell or squamous cell carcinoma resolved by excision. 6. Liver disease or liver injury as indicated by abnormal liver function tests at screening. 7. History or presence of impaired renal function at screening 8. Presence of significant pulmonary disease at screening 9. Ongoing respiratory infection. 10. History of acute coronary syndrome in the last 12 months; unstable angina; congestive heart failure; cardiogenic syncope; cardiomyopathy; or symptomatic arrhythmia, or current uncontrolled blood pressure. 11.
