On 9 January 2012, Cousins was admitted to Sir Charles Gairdner Hospital after suffering a fall at a drug rehabilitation clinic. He slipped while getting out of a shower, striking his head on a basin and injuring his neck. It was reported that Cousins had been experiencing continuing problems with illicit drugs, despite seeking help at several drug rehabilitation clinics, and that he had "never been clean for more than three months." It was also reported that he had recently undertaken an extreme drug binge lasting for approximately eight days. Cousins was committed by doctors to a suburban mental health unit under police escort on 13 January 2012 after suffering a four-day episode of drug-induced psychosis while being treated at Sir Charles Gardiner Hospital.
