Another child actress is busted with cocaine and heroin….and it isn’t a recent star.  Mackenzie Phillips, from the hit show One Day At A Time, was picked up in LAX.

More pictures after the jump…

The actress has a long history of drug abuse.  It was the reason why she was kicked off the show in the early 80s – she couldn’t keep clean.  Her co-star was Valerie Bertinelli, who did manage to stay clean and go on and have a better career.  Well, sort of since she married Eddie Van Halen, a notorious drug user and alcoholic.
