Summary: Oz, 55, shared part of an audio conversation he had with Chachoua, who revealed he was so confident in Sheen's treatment that he injected some of the actor's blood into himself. "I drew some blood from him and I injected myself with it and I said, 'Charlie, if I don't know what I'm doing, then we're both in trouble now aren't we?' " Chachoua told Oz by phone.
