Cannabis in Oncology — Switzerland 2026
In oncology, cannabis is used in Switzerland for chemo nausea, appetite loss, pain and palliative care — not as an anti-cancer therapy, but for quality of life.
Cannabis does not cure cancer. It helps well for chemo-induced nausea and vomiting (CINV), moderately for appetite loss (cachexia) and in palliative care. Preparations: dronabinol drops, Sativex® off-label, flower. Prescription: oncologist or palliative doctor, or CannabisClub consult 50 CHF. In advanced disease, realistic chance of basic-insurance coverage under Art. 71a HIO.
Where cannabis clearly helps in oncology
Chemo-induced nausea and vomiting (CINV): strong evidence — dronabinol is licensed in many countries where standard antiemetics (5-HT3, NK1) are insufficient. Off-label established in Switzerland.
Cancer-related appetite loss / cachexia: moderate evidence for dronabinol, common in palliative care for appetite, enjoyment and quality of life.
What cannabis does NOT do
Cannabis is not a cancer therapy and does not replace chemo, radiation or immunotherapy. Preclinical cell studies suggest antiproliferative effects — robust clinical anti-tumour efficacy is not established.
Honest doctors say this clearly. Avoid vendors who suggest 'cannabis cures cancer'.
Preparations & dosing
Dronabinol drops: for CINV 5 mg 1–3 h before chemo, repeat if needed. For cachexia 2.5 mg twice daily, slow titration.
Sativex® off-label: for cancer pain 4–12 sprays/day, often on top of opioids.
Prescription & reimbursement
Ideal route: your oncologist or the palliative team. If refused: cannabis clinic or CannabisClub referral (50 CHF flat).
Coverage chance under Art. 71a HIO: in advanced disease with documented failure of standard therapy and reasoned cannabis indication, approval rates are clearly higher than for other diagnoses.
