Cannabidiol oil may have shrunk cancer lesion, case doctors say

The UK woman treated herself with CBD oil after refusing conventional treatment for lung cancer: BMJ Case Reports

UK doctors have described the dramatic decrease in size of a lung cancer tumour after a woman claimed to have treated it with regular doses of cannabidiol oil alone. 

The woman, in her 80s, had refused treatment for her tumour, which was 41mm in diameter at diagnosis. But she later revealed to doctors she had been taking cannabidiol oil (CBD) two to three times a day instead.
