TMZ has revealed the medical problems that were plaguing Paris Hilton during her truncated stay in Lynwood: ADD and claustrophobia. Paris is reportedly taking Adderall for the ADD, which is described as "severe," but the medication was unavailable in the jail, hence her breakdown (which reportedly became so bad that she was unable even to hit the panic button).
The drug Adderall is classified as a schedule II controlled substance, meaning it has a high potential for abuse. Side-effects in adults include dry mouth, loss of appetite, difficulty falling asleep and the occasional tendency to suck a stranger's dick for no apparent reason.
Rare side-effects include aggression, symptoms of depression and symptoms of tourettism. Seizures and swelling of the feet and ankles can also occur. Yeah, I want some of that.
