Amy Winehouse

Context: Winehouse's battles with substance abuse were the subject of much media attention. In 2005, she went through a period of drinking, heavy drug use, and weight loss. People who saw her during the end of that year and early 2006 reported a rebound that coincided with the writing of Back to Black. Her family believes that the mid-2006 death of her grandmother, who was a stabilising influence, set her off into addiction. In August 2007, Winehouse cancelled a number of shows in the UK and Europe, citing exhaustion and ill health. She was hospitalised during this period for what was reported as an overdose of heroin, ecstasy, cocaine, ketamine and alcohol. In various interviews, she admitted to having problems with self-harm, depression, and eating disorders.  Winehouse told a magazine that the drugs were to blame for her hospitalisation and that "I really thought that it was over for me then." Soon afterward, Winehouse's father commented that when he had made public statements regarding her problems he was using the media because it seemed the only way to get through to her. In an interview with The Album Chart Show on British television, Winehouse said she was manic depressive and not alcoholic, adding that that sounded like "an alcoholic in denial." A US reporter writes that Winehouse was a "victim of mental illness in a society that doesn't understand or respond to mental illness with great effectiveness."  In December 2007, Winehouse's spokesman reported that the singer was in a physician-supervised programme and was channelling her difficulties by writing a lot of music. The British tabloid The Sun posted a video of a woman, alleged to be Winehouse, apparently smoking crack cocaine and speaking of having taken ecstasy and valium. Winehouse's father moved in with her, and Island Records, her record label, announced the abandonment of plans for an American promotion campaign on her behalf. In late January 2008, Winehouse reportedly entered a rehabilitation facility for a two-week treatment program.  On 23 January 2008, the video was passed on to the Metropolitan Police, who questioned her on 5 February. No charges were brought. On 26 March 2008, Winehouse's spokesman said she was "doing well." Her record company reportedly believed that her recovery remained fragile. By late April 2008, her erratic behaviour, including an allegation of assault, caused fear that her drug rehabilitation efforts had been unsuccessful, leading to efforts by Winehouse's father and manager to seek assistance in having her involuntarily committed. Her dishevelled appearance during and after a scheduled club night in September sparked new rumours of a relapse. Photographers were quoted as saying she appeared to have cuts on her legs and arms.  According to her physician, Winehouse quit illegal substances in 2008. In an October 2010 interview, speaking of her decision to quit drugs, Winehouse said, "I literally woke up one day and was like, 'I don't want to do this any more'." Drinking alcohol emerged as a problem with Winehouse abstaining for a few weeks then lapsing. The physician said that Winehouse was treated with Librium for alcohol withdrawal and anxiety, and underwent psychological and psychiatric evaluations in 2010, but refused psychological therapy.
