Love is scheduled to be arraigned Friday in Los Angeles, said Frank Mateljan, spokesman for the city attorney's office. Love's drug tests were still pending, he said.
Love, 39, was arrested Oct. 2 outside a Los Angeles home where she had allegedly broken the windows in an attempt to enter, according to police.
She was arrested and booked for investigation of using illegal drugs, posted $2,500 bail and was released.
Hours later, police and paramedics in Beverly Hills responded to an emergency call and took Love to a hospital to receive treatment for an overdose, police said.
Her representatives did not return a call for comment Wednesday, and had refused to discuss the case previously.
Love was arrested earlier this year in London for allegedly verbally abusing cabin staff on a Virgin Atlantic flight from Los Angeles. She was later released. She was also mentioned in December when a Beverly Hills physician was stripped of his medical license by the California Medical Board for prescribing addictive drugs on a cash-and-carry basis to celebrities.
The performer is the widow of Nirvana frontman Kurt Cobain, who committed suicide in 1994. She received a Golden Globe nomination for her role in the 1996 movie "The People vs. Larry Flynt."
