Cancer Survivor Replaced High-Dose Opioids With Medical Cannabis for Pain
A 27-year-old Ewing sarcoma survivor with intractable pain completely replaced high-dose opioids with THC-rich cannabis within 4 weeks, maintaining pain control and unexpectedly resolving a chronic infection over 9 months.
Quick Facts
What This Study Found
After initiating THC-rich cannabis (Bedrocan, 22% THC, 1% CBD, 1g/day), the patient's pain dropped from VAS 9-10 to VAS 2-3. Complete opioid discontinuation occurred within 4 weeks (from 120mg/day morphine equivalents). Over 9 months, a chronic draining fistula closed completely and CRP dropped from 9.6 to 2.3 mg/dL.
Key Numbers
Pain: VAS 9-10 → VAS 2-3. Opioids: 120mg/day morphine equivalents → 0 within 4 weeks. CRP: 9.6 → 2.3 mg/dL. Cannabis: Bedrocan 22% THC, 1% CBD, 1g/day. Follow-up: 9 months. Chronic fistula: complete closure. No adverse effects reported.
How They Did This
Single case report of a 27-year-old male long-term Ewing sarcoma survivor with chronic multi-drug resistant periprosthetic osteomyelitis. Supervised medical cannabis therapy initiated after refusing amputation. 9-month follow-up tracking pain, opioid use, inflammation markers, and fistula status.
Why This Research Matters
This case demonstrates that medical cannabis may enable opioid-free pain management in complex cancer cases. The unexpected resolution of chronic infection and inflammation raises intriguing questions about cannabinoid immunomodulatory effects beyond pain relief.
The Bigger Picture
The opioid crisis makes alternatives for cancer pain urgent. This case is remarkable not just for opioid replacement but for the apparent anti-inflammatory effect — the resolution of a chronic multi-drug-resistant infection that had persisted for over a decade is unexpected and warrants investigation.
What This Study Doesn't Tell Us
Single case report — cannot prove causation. Spontaneous improvement cannot be excluded. No blinding or control. The patient's strong belief in cannabis may contribute to pain improvement (placebo effect). Infection resolution may be coincidental.
Questions This Raises
- ?Can THC-rich cannabis consistently replace opioids in cancer pain?
- ?Did cannabis truly contribute to infection resolution, or was it coincidental?
- ?Should controlled trials investigate cannabinoid immunomodulation in chronic infections?

Evidence Hierarchy
Frequently Asked Questions
Can medical cannabis replace opioids for cancer pain?
In this single case, yes — a patient with severe cancer-related pain completely stopped opioids within 4 weeks of starting medical cannabis. However, one case can't prove this would work broadly, and controlled trials are needed.
Did cannabis help with the infection too?
The timing is suggestive — a chronic draining infection that persisted for years resolved after cannabis initiation, with inflammation markers dropping. However, this could be coincidental, and the authors cannot establish causation from one case.
