Help me find name of song/video

There's a video where a girl in short shorts walks up a flight of stairs, sits on a couch in front of a Technics turntable, puts on a song and lights a spliff, and the video clicks into slow motion as the smoke rolls up her face, it cuts back and forth between two girls and at one point they're wearing a plastic wolf mask. The song is a mellow trippy tune with a female vocal that's playing backwards. Does anyone remember what this song/video is? It's probably about ten years old or more.
