Bobbi Kristina Brown used heroin, cocaine regularly in recent months, report says

ATLANTA, Feb. 21 (UPI) -- Bobbi Kristina Brown had been battling an addiction to drugs for the past several years and was intoxicated the morning she was discovered unresponsive in her bathtub, People magazine reported Saturday.

The publication cited unnamed sources as saying the 21-year-old daughter of Bobby Brown and the late Whitney Houston regularly used heroin, cocaine and Xanax in recent months, and was also a heavy drinker. She reportedly had sought treatment at rehabilitation facilities on numerous occasions.

Bobbi Kristina Brown has been hospitalized in Georgia on life support and in critical condition since Jan. 31. Her father has publicly said her family continues to pray for her recovery and has no plans to remove her from life support.

Houston accidentally drowned while intoxicated in a hotel bathtub after years of substance abuse Feb. 11, 2012. She was 48.

Bobby Brown has also been candid about his own past addiction issues.
