At the age of ten, Deryn Blackwell was diagnosed with leukaemia. Two years later he developed another rare form of cancer called Langerhans cell sarcoma, making him one in seven billion. After four unsuccessful bone marrow transplants, he was moved to a children’s hospice where he began to plan his funeral.
But despite being given just days to live, somehow Deryn battled his way back from the brink as his body began to produce white blood cells - it was nothing short of a miracle.
Deryn’s desperate mother Callie is finally ready to reveal an untold secret – she credits Deryn’s amazing fight back to full health to medicinal cannabis and hopes to stimulate debate and medical research into the treatment. Callie and Deryn, now 17, join us on the sofa.
