Actress Mackenzie Phillips hit new lows in her life when pain medication ended a decade of sobriety and led to her arrest for cocaine and marijuana possession in 2008.
Before police caught the former One Day At a Time star with the drugs and arrested her, Phillips had become a virtual recluse, desperate for a heroin fix.
She tells U.S. TV show Access Hollywood, "I rarely left my house and there were needles everywhere. There was blood on the ceiling. That's how bad it got."
Before that, the actress had been clean for 10 years after turning her back on drugs when she was 32.
Now, over a year sober, she insists she hasn't used drugs since her arrest on 27 August, 2008.
She adds, "The turning point for me was having those cuffs slipped on me... I kept saying to the woman who was arresting me, 'Please don't bust me, I'm somebody's mother.'"
Phillips was eight months sober when she started shooting reality show Celebrity Rehab with Dr. Drew. The show debuts in America on Thursday (07Jan09).
