The results of second slot of forensic test reports were declared by Mumbai police on Friday.
Of the total 90 people seized from the sundown rave party on May 20 at Hotel Oakwood Premier in Juhu, 86 have been tested positive for drugs, excluding two men and two women.
According to the Mumbai police who raided the posh hotel, 110gm of cocaine, 64gm of charas and several tablets of Ecstasy were found at the venue.
The blood and urine samples of all party goers were tested at Mumbai's Kalina Forensic Lab to check the presence of drugs and alcohol.
More than three dozen people, including top names from the entertainment industry, and cricket world, who claimed innocence in the high-profile party, are among the ones who either consumed narcotic drug or psychotropic substance at the party.
The accused are likely to be arrested soon under the Narcotics Drugs and Psychotropic Substance (NDPS) Act, while a case has already been registered, the police said.
Police said, Indian cricketer Rahul Sharma and IPL player Wayne Parnell, who were among the ones detained from Mumbai's post hotel, have also been tested positive.
