Pop-star Michael Jackson had a secret implant done to nullify the intake of drugs by blocking the pleasure receptors, thesun.co.uk reports.
The device used in the implant dosed him with Narcan to fight drug addiction.
Narcan is a drug prescribed to counter the effects of heroine or morphine.
The implant was found in the star's body after he died, but came to the light in newly released court papers.
The singer died June 2009, at the age of 50.
