On his 13th birthday, Osbourne got drunk for the first time on whisky; by the time he was 14, he was drinking regularly and had started smoking marijuana. He started partying heavily, and made headlines on 21 April 2003 when he was admitted to a child psychiatric ward for an addiction to OxyContin. Osbourne's drug addiction escalated after his mother was diagnosed with cancer; he was as well battling with his own depression. His self-destructive behaviour came to a head when he attempted suicide by taking a cocktail of prescription pills and cutting his hands with shards of glass after hearing his girlfriend's ex-boyfriend pick up her phone when he called her. He woke up 12 hours later. Osbourne continued with his drug use until he realized that he "never wants to feel this way ever again" and admitted himself into an adolescent psychiatric ward. He spent 10 days detoxing and was moved to an adolescent rehabilitation center in Malibu, where he enrolled in a recovery program.
