Thirteen bags of cocaine were allegedly found in Boy George's New York home when he was arrested, papers released by Manhattan's district attorney show.
Police attended Boy George's home following reports of a burglary
The singer was charged with possession of drugs and faces up to five and a half years in prison if found guilty.
His lawyer, Lou Freeman, previously said a "small amount" of drugs was found at Boy George's apartment.
Mr Freeman said the star, who must attend a Manhattan court in December, did not know who owned the cocaine.
"He's a very social person. He has a lot of people over to his apartment," Mr Freeman added.
Boy George, whose real name is George O'Dowd, called police on Friday to report a burglary.
Officers allegedly found drugs next to a computer in his apartment.
Substances found in the 13 plastic bags weighed more than one-eighth of an ounce (3.5g) in total, the legal papers stated.
"That is a sizeable amount of drugs," said Maggie Gandasegui from Manhattan's Special Narcotics Prosecutors office.
O'Dowd, 44, faces one charge of drug possession and a charge of falsely reporting an incident. He returned to London on Sunday following his release.
After attaining global success as a member of pop group Culture Club, Boy George became addicted to heroin but kicked the habit to become a solo artist and DJ.
His autobiographical musical Taboo became a hit in London but closed after less than three months on Broadway.
