Bobbi Kristina has been doing drugs long before her mother, Whitney Houston died. The fact her mom died because of drugs has not stopped Bobbi Kristina from doing more drugs and booze and things have got so bad that Star Magazine says the family staged an intervention to get her to stop. It failed. I think the problem is going to be that no one was there to ever stop Whitney from doing drugs. There were just not enough people who cared about her who also wanted her to stop and lots of people around her were doing drugs with her. If someone is paying for the drugs you are going to get a whole lot of people around you who are happy to be your friend and why would thy ever tell you to stop. Bobbi has way fewer people than Whitney around her, but even less who want her to stop. Plus, what consequences have there been for Bobbi? She is becoming richer by the second because of her mom's post death record sales. Oh, Bobbi has the brand new role on a television show despite no acting experience. She is becoming more famous and the drugs are probably getting a little better.
