Lindsay Lohan Released from UCLA Rehab

Image by Fonzie's cousin via FlickrLindsay Lohan has been released from her rehab facility at UCLA where she was been held after been released from Jail.  Lindsay was released 67 days early at her doctors recommendation to the judge who gave the green light for Lindsay to be released.  Lindsay is set to continue her rehab program in an out patient program.  
There has been speculation that Lindsay's erratic behavior leading to her arrest was due to a misdiagnosis of Attention Deficit Hyperactivity Disorder and the medicine (Adderall) she was prescribed for the disorder.  
An addiction specialist told TMZ "that people who take Adderall when they don't need it can experience similar effects as people who use cocaine or methamphetamine."
That could definitely explain some of Lindsay's crazy behavior, but what about all that white powder that always seemed to be following her everywhere she went.  How can they explain that?!
