Whitney Houston's brother, Michael, says he feels responsible for the superstar's death because he introduced her to drugs.
During an interview on "Oprah's Next Chapter," which aired Monday, he said, "I think probably the first time she ever did it (cocaine), it was with me. But you have to understand during the '80s, it was acceptable to the entertainment world. It was available. It wasn't a bad word ... (like it is) now. We just didn't know. ... We were traveling, we were on the road, we were young -- late 20s -- had money. We just got caught up. And it's been a battle ever since. ... It's painful. I feel responsible for (her drug problems), that I let it go so far. ... I taught her to drive. We played together ... and then when you get into drugs, you do that together too. It just got out of hand. Drugs are rough."
Michael says he will never forgive himself for setting a bad example for his little sister: "(It's) something I'll live with for the rest of my life."
Michael also reveals that Whitney told him he shouldn't accept the blame for her problems, adding, "She always told me, 'I'll never let anyone make you feel bad or responsible for what I do. I'm a grown woman.'"
Previously, the singer's addictions have been blamed on her troubled ex-husband, Bobby Brown.
Houston died by drowning last February due to heart disease and the effects of cocaine use.
