Lindsay Lohan: Body by Adderall?

By: Betsy Waldman / May 5, 2009

The secret to Lindsay Lohan‘s dramatic weight loss may have been discovered.

Us Magazine reports that the 22-year-old actress has been taking the drug Adderall—typically used to treat attention deficit hyperactivity disorder—and may not be sticking to the recommended daily dosage.

“She takes Adderall all the time,” a source claims. “She gets jittery because of the way the pills affect her. It’s a major reason why she’s losing weight.”

Well, that’s one possible explanation. Of course, she could also be dropping weight due to the constant stress of wondering where her next job is coming from.
