In February 2007, Jamieson attended the Odyssey House drug detoxification unit in Sydney, Australia, to overcome his addiction to crystal methamphetamine, also known as "ice". Jamieson claimed the information had been leaked to the media a week later by a nurse, and said that he felt "My confidence, or my confidentiality, was completely raped". In July 2007, he went public in an interview with Andrew Denton on the TV program "Enough Rope", and spoke of stealing from his bandmates to fuel his drug use and becoming estranged from his wife. Jamieson continued his rehabilitation at a private clinic with the support of Julie, his family and bandmates.
