David, 29, is nothing less than a miracle. At the age of 18 he contracted leukemia and underwent a dangerous bone marrow transplant that he survived. Prescribed painkillers to cope with his treatment, David became addicted and now, a decade later, consumes massive amounts of Oxycodone. He uses up to 1200 mg a day, which he injects or snorts. Trading one kind of sick for another, David’s erratic, angry and manipulative behaviour has cost him every friend he ever had. His lonely existence is punctuated only by the presence of his mother, and the ever-present need to secure more oxy. Having fought the battle to save his life from cancer, David now is watching his addiction take it away. Interventionist: Andrew Galloway
