It’s been almost a year now since Whitney Houston’s tragic passing, but her memory will live on forever. Her brother recently sat down with their mother Cissy Houston for an interview on Oprah’s Next Chapter, and revealed that HE was the one that cut Whitney hooked on the drug that ultimately led to her downfall. So sad. Though his guilt is overwhelming, he explains, “You gotta understand at the time, the 80s, it was acceptable.” Watch the clip below. RIP, Whitney!
