70′s teen heartthrob Leif Garrett, who has suffered with substance abuse in his adult life (which was famously chronicled in an episode of VH1‘s Behind the Music back in 1999), was arrested again last night on charges of drug possession. TMZ reports that Garrett was arrested early Monday morning at a Metrolink commuter train station in downtown LA after he was found with a controlled substance on his person:

Leif Garrett was arrested Monday morning in Los Angeles for possession of a controlled substance. The former teen idol was busted at 11:20 AM at the Metrolink station in downtown Los Angeles by the L.A. County Sheriff’s Department. Garrett was taken into custody and placed behind bars. He wasn’t released until this morning. Garrett’s been busted on the Metro Red Line before — back in 2006, he was caught for allegedly riding without a ticket … but heroin and Quaaludes were found in his possession. He was sentenced to 90 days in jail for the incident. Garrett is due back in court on February 24.

Naturally, the photo above is from his younger, more successful days. Leif doesn’t look like this anymore. Ugh. I remember being so taken with Garrett‘s episode of Behind the Music (back in the early days of the series when it was still really good) and then being so disappointed when Garrett got busted for drugs back in 2006. Clearly, it would seem that Leif Garrett has yet to completely overcome his demons. Perhaps Garrett will be able to parlay this latest arrest into another stint on a VH1 show … Celebrity Rehab, perhaps?

UPDATE: TMZ has scrounged up Leif Garrett‘s newest mug shot — which you can see after the jump …

It turns out that homie got busted with black tar heroin in his possession. Just … sad.
