Amy Winehouse [SEP] Substance abuse and mental illness
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.
