It's Miley Cyrus getting high

One of Miley Cyrus' friends is a little bit richer this morning after they sold a video of the singer taking a rip off of a bong a few weeks ago. TMZ says she's smoking the legal herb salvia, but I have my doubts:
The video was shot during a party at Miley's L.A. area home 5 days after her 18th birthday. According to a source connected with Miley ... the smoke filling the bong is a natural herb called salvia which has psychedelic qualities. Possession of salvia is legal in California. As for the video ... the source tells us it was shot by one of Miley's friends --  and the theory is someone stole or copied the video from that friend's camera.
Clearly Miley's people knew this video was hitting the web and this salvia excuse is just a little damage control. Trust me, that's weed she's smoking. How do I know? There's a dude eating Frosted Flakes out of the box behind her.
