London, July 10 : Late Michael Jackson had apparently hinted at his addiction to drugs in a song he wrote about 20 years ago.

The hand-written lyrics also hint at suicidal thoughts.

"This stuff ain''t good for me," the Mirror quoted him as having admitted in the song.

Other phrases in the song include: "Life''s an aggravator, I plan to give it up" and "I hurt my backbone, I start to givin'' up, the bills are pilin'' up".

The lyrics, written more than 20 years ago, are believed to be a self-portrait of the Late King of Pop.

The lines were written for a song that failed to make it onto the troubled star's `Bad' album, and are due to go under the hammer in America next month. (ANI)
