When she was 12 years old, River contracted acute myeloid leukemia, which is a cancer of the bone marrow and blood. She briefly underwent conventional treatment but the chemotherapy left her with no immune system and she contracted an incredibly rare fungal infection that spread to her brain and left her blind. After 11 months in the hospital and being treated with antifungals, she was sent home. Her mother administered cannabis oil and over the ensuing months she fully recovered, although she remains blind. Listen to the heartwarming story told by mother Luna and her now 16-year-old daughter, River from the UK.
