Cannabis oil / "Rick Simpson oil"

That concentrated cannabis extract taken orally cures cancer outright, and that legal restriction rather than lack of evidence explains its absence from oncology.

Rick Simpson, a Canadian who treated a skin lesion with cannabis extract in 2003 and published the protocol freely. His 2008 documentary "Run From The Cure" framed it explicitly as suppression. The story has been carried further by legalisation advocacy, where the medical claim and the political claim reinforce each other.

• “The oil did not shrink anything, and I wish someone had told me that before I delayed treatment for four months. But it gave me my appetite back when nothing else would.”

  Patient forums; the split outcome is the characteristic pattern for this claim

Cannabinoids show antitumour activity in cell culture and animal models, which is why the research continues rather than being dismissed. No human trial has shown cancer remission. Meanwhile the palliative evidence is genuinely strong: cannabinoids help with chemotherapy-induced nausea, appetite loss and some pain, and are prescribed for exactly that in many countries. This entry is the clearest illustration of the archive's point, because a substance that demonstrably helps cancer patients is being sold as something that demonstrably does not cure them.
