Now that Whitney Houston’s body has been laid to rest, daughter Bobbi Kristina is left to face the world without her mother’s guidance and many are fearing the worst will happen to her. Rumors hinted at possible drug use by Bobbi Kristina right after her mom’s funeral. Following the ceremony, Bobbi Kristina disappeared and family members frantically tried to find her. According to those connected with the family, Bobbi Kristina has struggled with substance abuse for the last three years. In March of last year, photos surfaced of the young girl snorting cocaine. The photos were supposedly taken by Bobbi Kristina's boyfriend at the time, who said that she is addicted to cocaine. A family friend says grandmother Cissy and other family members know about her drug problems and “have been trying to keep her straight even before Whitney passed. But losing your mother and the life you're accustomed to all in one day is enough to send anybody off the deep end."
