Whitney Houston's Daughter, Bobbi Kristina was reportedly under the influence of drugs the morning she was found unresponsive in a bathtub in her Georgia home last month.
The 21-year-old regularly used heroin, cocaine and anti-anxiety drug Xanax following the death of her mother, Whitney Houston, in early 2012, sources told People magazine.
One person said Brown had been "in and out" of rehab during the past three years, adding that she had been "distraught" over the February 11 anniversary of her mum's death.
Another source said Brown had unnamed drugs in her system when she was found face down and not breathing in her Georgia home on January 31.
And while no hard facts have been presented yet in this extremely sad situation – it seems clear that Bobbi Kristina never really stopped grieving after the loss of her mother.
"How thin she had gotten is an indicator. 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," another source added.
Toxicology reports showed Whitney Houston had marijuana, Xanax, the muscle relaxant Flexeril and the over-the-counter medication benadryl in her system when she died — also at home in the bathtub.
Brown remains in a medically-induced coma at Emory University Hospital in Atlanta.
