NEW YORK  - Last December, Miley Cyrus took the bong hit viewed around the world.

Now the "Hannah Montana" star has expressed regret for her dalliance with the psychedelic herb salvia, footage of which leaked online.

"I'm not perfect," Cyrus recently told Marie Claire magazine. "I made a mistake ... I'm disappointed in myself for disappointing my fans."

Salvia is a legal drug in most states including California, where she reportedly smoked it. She was asked, "But do you really think it was a mistake? Obviously college kids your age all over America are smoking bongs with a lot more than salvia in them."

The Disney star's response: "But they're not Miley Cyrus. They're not role models. So for me it was a bad decision, because of my fans and because of what I stand for."

Reportedly filmed just five days after her eighteenth birthday, the video of Cyrus' salvia bong hit features the singer/actress declaring that she was "having a little bit of a bad trip."
