LOS ANGELES (GN)Michael Jackson reportedly had a secret medical implant to help him battle addiction to prescription drugs. The ‘Beat It’ hitmaker - who died in June 2009 after being administered a lethal dose of Propofol by his doctor, Conrad Murray - was allegedly fitted with the device, which effectively makes drug taking pointless by blocking pleasure receptors in the brain, in 2003 to stop him getting enjoyment from opiates.
