Bobbi Kristina Brown was abusing drugs in the days prior to her death, according to her friend and former roommate Danyela Bradley.

"She smoked marijuana, she probably smoked crack often, and also did heroin," Bradley claimed in a newly-released videotaped deposition connected with a car accident both girls were involved in back in late January, just days before Bobbi Kristina was found face down and unresponsive in her Georgia home's bathtub, Us Weekly reported.

Bradley reportedly met Bobbi Kristina, the daughter of Bobby Brown and the late Whitney Houston, through Bobbi Kristina's longtime boyfriend Nick Gordon and his buddy Max Lomas.

"Me and Krissy became very, very close," Bradley said. "Our relationship just grew as if we had [grown] into sisters up until her passing."

Bobbi Kristina lived with Bradley, Gordon and Lomas in a house together for about a month -- right up until the day of Bobbi Kristina's hospitalization. She remained in a medically induced coma for about six months before she died July 26 at 22-years-old.

"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," Bradley explained in the deposition, according to Us. "[But] I guess after a few weeks she just didn't really hide it."

Bradley insisted she never did hard drugs with Bobbi Kristina, nor did she ever see Bobbi Kristina do them firsthand, but they would smoke marijuana occasionally.

"I would just visually see her physical being and I could just tell," Bradley noted, adding that Bobbi Kristina would get "very sleepy, nod off" and "kind of keep to herself" when she did heroin. Bobbi Kristina would also allegedly not be talkative when she did crack.

Gordon had recently been slapped with a civil wrongful death lawsuit filed by Bobbi Kristina's conservator Bedelia Hargrove. The lawsuit listed disturbing details of the events that allegedly transpired leading up to Bobbi Kristina's body being found -- including how she and Gordon allegedly got into a terrible argument during which he gave her a "toxic cocktail" and nearly knocked a tooth out of her mouth.

Gordon's legal team had told Us in a statement the lawsuit was "slanderous and meritless."

Bradley, however, said the couple "had a very happy, loving relationship," and that Gordon sometimes referred to himself as Bobbi Kristina's "husband," although the pair wasn't legally married to her knowledge.
