After pleading guilty to one count of felony drug charge in a Los Angeles court on Friday, Mackenzie Phillips was sentenced to an 18-month drug diversion program.

The 48-year-old actress, best known for her rebellious role in the ‘70s CBS sitcom “One Day at a Time,” agreed to enter rehab after an August arrest at the Los Angeles International airport, when security guards discovered she was carrying heroin and cocaine during a routine inspection.

Mackenzie Phillips was officially charged with two felonies, for possession of heroin and cocaine, as well as a misdemeanor charge of unauthorized possession of a hypodermic needle or syringe.

However, as part of a plea deal, prosecutors dropped the heroin and syringe possession counts and, in addition, if the daughter of The Mamas and the Papas lead singer, John Phillips, successfully completes the drug deferment program, the case will reportedly be written off.

Mackenzie Phillips told Judge Keith L. Scwartz on Friday that she was grateful for the fact that law enforcement saved her life, while the judge told the former “American Graffiti” star that she was “making tremendous progress.”

The actress has been battling drug addiction for a very long time now, as she admittedly smoked marijuana for the first time at only 13 and shot up at 17. Her drug and alcohol issues also caused her double dismissal from “One Day at a Time.”
