Lindsay Lohan's estranged father says she suffers from multiple addictions, including alcohol and the painkiller OxyContin.
The 20-year-old actress is back in rehab after crashing her Mercedes, being arrested on suspicion of driving under the influence and being photographed slumped in the passenger seat of a friend's car.
"I spoke to the people treating Lindsay, because I wanted to make sure she was getting the right care," Michael Lohan said. "And I'm satisfied they are doing the right thing for her, helping her detox from the painkillers. That's a very important step."
