The Forgetting Sarah Marshall star, a former heroin addict and alcoholic, will talk about his rehab experiences and recovery when he appears at an inquiry into drugs policy on Tuesday (24Apr12).

Members of the House of Commons' Home Affairs Select Committee will question Brand about ""the nature of addiction and how it is viewed by society"" as well as his upcoming documentary about drugs.

Committee chair Keith Vaz says, ""Hearing from those personally affected by drugs use is essential to our inquiry.

""I welcome Russell Brand's openness about his addiction and recovery. I hope that his experiences will help us understand the nature of addiction and the impact that it has on addicts and those around them.""
