At the age of 10, Deryn Blackwell was diagnosed with leukaemia and two years later developed another, yet rare, form of cancer called Langerhans cell sarcoma. After four unsuccessful bone marrow transplants he was given just days to live, but somehow Deryn battled his way back from the brink and has since made a full recovery. Deryn’s mother Callie revealed that she had been giving him medicinal cannabis and credits it with saving Deryn’s life.

Obviously, cannabis is not a recommended treatment for cancer. There is a lot of anecdotal evidence on the internet and stories like Deryn’s that have inspired people to take matters into their own hands and try it themselves. Obviously, in the lab medical cannabis has also shown much promise, but there have yet to be clinical trials when it comes to cannabis and its ability to fight cancer.
