The actress, who has son Jaden, 15, and daughter Willow, 12, with her husband Will Smith, shocked the showbiz world last week when she admitted she had battled "many addictions, of several kinds" in her past, reported Contactmusic.
Her former stepfather, lawyer Warren A Brown, has now confessed to regularly using cocaine with her mother Adrienne Banfield Jones in the house when Jada was growing up in the late 70s and early 80s.
"At times I felt guilty. I remember just the three of us in the house together and I knew I was high and so was her mother. She didn't know though, she was too young to recognise it. She didn't see us doing anything. But I felt really bad because I thought this little girl deserves better than her parents addicted," he said.
Warren fears Jada, now 42, may have suffered in the aftermath of his divorce from Adrienne in 1986 since he deliberately distanced himself from her.
"It was me and Jada. I was raising her while her mother was working and in college. We spent a lot of time together...My new wife asked that I distance myself from her. So it was a sudden departure for Jada, and it was always just the two of us. Anyone who knew of our relationship would not disagree that my estrangement with her may have played a part," he added.
