Bobbi Kristina Brown was on drugs the morning she was found unconscious in a bathtub, multiple sources revealed to People Magazine.

According to the sources, the 21-year-old daughter of late superstar Whitney Houston used cocaine, heroin and Xanax a lot in months leading to her Bathtub incident. An indication she was under influence of drugs was that she often looked high, making incoherent speeches and slurring them.

It has been revealed that Bobbi was “in and out” of rehab in the three years since she lost her mother. With the third anniversary of her mother’s death drawing near, she was “distraught” and so decided to cling on to drugs.

“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,” the source added.

Bobbi Kristina is still in a very critical condition. The 21-year-old went through tracheotomy this week to rearrange her breathing tubes.
