Whitney Houston’s daughter, Bobbi Kristina Brown, is spiraling out of control after her mother’s tragic death, but drug use has been a problem for quite a while for the troubled teen.

A shocking new video shows Bobbi Kristina smoking marijuana from a three-foot-tall bong, inhaling the swirling pot smoke so deeply that she nearly collapses in a coughing fit!

The wild party girl that Ashton Kutcher hooked up with in San Diego was at a booze fueled party when they met but she’s no stranger to what looks like drug paraphernalia in an exclusive photo of her obtained by Star magazine.

In the scandalous snapshot, Sara Leal is holding a bong up to her mouth, looking at the camera as she poses.

The 23-year-old bombshell beauty has been the life of the party many times. From seductively licking body shots off a girl friend’s belly to dancing wildly around, Sara knows how to have a wild time.

Miley Cyrus is having some fun on the set of her new movie So Undercover. The 18 year old star is seen in these photos clowning around with a co-star and posing for pictures.

Miley's exhausted dad Billy Ray Cyrus recently calls his daughter's actions "beyond" his control.

This latest Miley scandal comes just weeks after she was videotaped smoking salvia from a bong.  The herb is legal in California and most states but can make users as high as those using LSD!

On Friday, a video of Miley Cyrus inhaling smoke out of a bong surfaced and while initial reports downplayed the substance since it has legal status in California, RadarOnline.com has learned that salvia has very serious effects similar to those of LSD.

“It’s a psychedelic drug, a hallucinogen and has the same effects as LSD,” Clare Kavin, a registered addiction specialist and administrative director of the Waismann Method, told RadarOnline.com. While salvia was originally used in Mexico during religious ceremonies, Kavin says those in the US use it strictly for its hallucinogenic properties that can lead to disturbing behavior.

“It can cause psychosis, your motion sensors are off, you can feel like you are in two places at the same time, you have 2-D visions,” she added. In the video, a rambling Cyrus can be heard saying: "I'm having a little bit of a bad trip. Is that a Liam lookalike -- is that my boyfriend? Is that me tripping? Does that look like Liam at all? I want more of that s---.”
