Bobbi Kristina Brown had drugs before drowning

People magazine reveals that the daughter of Whitney Houston and Bobby Brown used drugs shortly before the tragedy.

Sources close to Brown told the publication that she used heroin, cocaine and Xanax on a regular basis recently, besides drinking.

“This girl was trying hard, but she didn’t have any support system,” a source told People. “She was still dealing with a lot of grief over her mother.”

Brown is also said to have had a hard time dealing with the anniversary of her mother’s death on Feb. 11, the source adds.

“How thin she had gotten is an indicator,” the insider saqid. “This girl was trying hard, but she didn’t have any support system. She was still dealing with a lot of grief over her mother.”

Unfortunately, her condition hasn’t improved despite the various measures taken by the medical staff.
