Miley Cyrus Smoking Salvia with Bong (VIDEO)

Uh oh: Miley Cyrus was caught doing something inappropriate – but don’t worry fans, it’s 100% legal.

TMZ has obtained video of the Hannah Montana starlet smoking salvia–a legal herb that has psychedelic qualities.

In the video, Miley takes a hit of salvia from a bong and proceeds to hallucinate about her ex-boyfriends. “I’m having a little bit of a bad trip,” Miley says, “Is that a f***ing [Liam Hemsworth] lookalike over there? Is that my boyfriend? Is that Liam?”

After Miley’s friend tells her that she is being a “buzzkill,” she starts to dissolve into a fit of giggles while her friends look on.

According to TMZ, the video was taken just five days after Miley turned 18, so Miley was not participating in any illegal activities.

This isn’t the first time that Miley has been videotaped doing something mildly inappropriate. Earlier this year, Miley was spotted dirty dancing with Adam Shankman, a much-older male producer from her film The Last Song.
