LOS ANGELES (CBS) — A new video on TMZ.com purportedly shows Miley Cyrus using a bong to smoke the psychedelic drug Salvia.

The website quotes a source who says one of Miley’s friends recorded the moment at the singer’s house during a party five days before her 18th birthday.

Possession of Salvia is legal in California, but there have been efforts to outlaw the drug.
