A cancer patient who accepted the disease would kill him saw his tumours shrink – by taking drops of cannabidiol (CBD) oil each day.
The 81-year-old, who hasn't been identified, repeatedly refused chemotherapy and other treatments to prolong his life.
Instead, the ex-smoker, believed to be from the Stoke-on-Trent area, opted to take CBD oil for three months to tackle his lung cancer.
Doctors have now published stunning scans, showing how doing so halved the size of his tumours and reversed the progression of his disease.
The tale has been published in a medical journal, where doctors claimed 'CBD may have had a role in the striking response'.
