After much speculation about her drug use following the death of her mother Whitney Houston, Bobbi Kristina has been caught on camera smoking from a large bong. The EnquirerPlus has published a photo of the teen taking hits, presumably of marijuana.

"Bobbi Kristina was staying with friends at the school and she brought along a big bag of pot for the party," an alleged source at the party where the footage was captured told RadarOnline. "The party was well underway by the time I got there around 11 PM When I left at 6 AM the next day, she was still partying hard," the insider added.

In the video, Bobbi asks for a lighter from a fellow party-goer, lights a three-foot bong and takes several hits while fighting back coughs. "Between tokes, Bobbi was drinking shots of Grey Goose and Skyy Blue vodka, and sipping a mixed vodka drink," the insider reported.

"She's obviously a seasoned partier. With the amount of pot and alcohol she was using, I would have passed out, but she was still going strong."

Bobbi's family have become increasingly concerned with her drug use since the death of her mother, reportedly recently staging a failed intervention.
