Bobbi Kristina Brown often used drugs prior to death: Friend

Los Angeles: Bobbi Kristina Brown allegedly used drugs quite frequently before she was found unconscious in a bathtub in her Georgia home back in January.

According to transcript of a videotaped deposition, Bobbi's friend Danyela Bradley claimed that she eyewitnessed her smoking marijuana, reported Us Weekly.

"She smoked marijuana, she probably smoked crack often, and also did heroin," Danyela, who was also Bobbi's roommate, said in the deposition.

"When I first lived with her I didn't know that she had actually had a problem with drugs until I had lived with her... For a couple of weeks but I guess after a few weeks she just didn't really hide it."

While Danyela never saw Bobbi using cocaine or heroin, she claimed that she could tell from her late friend's behaviour.

"I would just visually see her physical being and I could just tell," Danyela said, explaining that Bobbi would get "very sleepy, nod off" and "kind of keep to herself" when she did heroin, and would "just be not even talkative" when she did crack.
