Lindsay Lohan Wants to Keep Taking Prescription Pills in Rehab: Report

Can someone please explain rehab to Lindsay Lohan?

The actress has one stipulation when it comes to entering a "lock down" facility for 90 days … she wants to keep using Adderall.

Sources tell TMZ that she only agreed to the plea deal of rehab instead of jail as long as she is still allowed to take the drug, which is used to treat attention-deficit/hyperactivity disorder, but is often abused by others looking to achieve a high similar to cocaine.

Last May, her outspoken father Michael Lohan blasted her prescription pill use, which was revealed in court documents to include anti-depressants Zoloft and Trazodone, Adderall, and the super-strength painkiller Dilaudid for her previous dental issues. "The meds that they give her are meds that they say she needs, but she doesn't need them," Michael said at the time. "They kind of make her flat. She's not acting at a full potential. It's like the screen is down over her."

Although Lohan's rep did not respond to omg!'s request for comment about the Adderall, her attorney Mark Jay Heller is insisting her usage of the prescription drug was never discussed with the prosecutors. "Prosecutors or the court would never interject themselves into medical determinations," he told the New York Daily News. "Patients traditionally apprise facilities of what medications, if any, they're prescribed, and after a full series of medical evaluations, each facility determines what medications, if any, are going to be allowed. This is never dictated by the patient. It's always determined by medical staff who are well qualified."

Adderall or not, Lohan's upcoming rehab stay is already complicated. Although the judge ordered her to a "lock down" facility, she wants to get treatment in New York City, but that reportedly doesn't exist in the state. TMZ also reports that prosecutors in her case are determining what their next move will be … will she go to a regular rehab or serve those 90 days behind bars?

Until then, she is getting the partying out of her system. Since last week, the 26-year-old has been in Brazil to promote the clothing line John John Denim. As omg! reported, she partied at a nightclub in Sao Paulo as part of her $100,000 deal … but was later photographed hiding under a table so she wouldn't have to sign autographs for fans.

Before going to South America, Lohan was partying up a storm in L.A. Not only was she following around her new boyfriend's band, but she also managed to sneak in a little face time with another guy she was linked to: The Wanted's Max George. E! News reports that she paid a secret visit to the boy band's house, where they are currently filming their reality show for the network … so hopefully we'll see her antics pop up on an upcoming episode.
