Amount of cocaine in Whitney Houston's system unclear
Houston, 48, was found lifeless and submerged in a bathtub at the Beverly Hills Hilton on Feb. 11 by friends and family. She had been taking part in pre-Grammy events and had planned to attend a party for her longtime mentor Clive Davis at the hotel.
In addition to the cocaine, Ed Winter, deputy chief of coroner investigations, said marijuana, Xanax, Flexeril and Benadryl were found in her body. Xanax is traditionally used as an anxiety treatment. Flexeril is a muscle relaxant and Benadryl addresses allergies and can be used as a sleep aid.
Houston had a long history of drug addiction.
A couple days before she died, Houston drew the attention of reporters and security staff with her erratic behavior, dripping sweat and disheveled clothes.
