GRINSPOON frontman Phil Jamieson has spoken of the depths of his ice addiction, including stealing money from his bandmates and the realisation he had become a junkie. Jamieson, lead singer of the Australian rock band named after illicit drug expert and Harvard Medical School professor Lester Grinspoon, says he began using crystal methamphetamine in 2004, recreationally at first. After two years of using the drug, along with cocaine and ecstasy as a source of musical inspiration, the married father of two says he became an everyday ice user on the brink of a psychological, career and family melt-down.
