Bobbi Kristina denied the speculation, insisting the photographs were set up by an ex-boyfriend to look as if she was indulging in narcotics.
New rumors circulated suggesting the teen was heading to a rehabilitation center to ensure she did not follow the same path as her famous parents, who have both battled with drug addiction.
But she has now taken to her Twitter.com page to take aim at the reports, writing, "Excuse me but I'd like to say that I am NOT going to rehab? I'm perfectly healthy and I am not addicted to anything but life.
"Home with the family_ pffft media cracks me up ! Rehab my a**, think what you want, but I'm a blessed perfectly healthy young lady."
