Three juveniles were arrested Thursday after on April 4 Boulder police had received a complaint by Nevin Platt Middle School officials who said a student had brought two prescription drugs to school to give them to another student in exchange for alcohol.

The prescription drugs were Strattera and Concerta, two medicines usually prescribed in the treatment of attention deficit hyperactivity disorder.

According to school officials, the student who got the drugs gave one pill to his colleague who swallowed it and then went home sick. Another student kept the remaining pills until the end of the school day, said Detective Cmdr. Phil West.

Two students have been charged with distribution and possession of a Schedule II Controlled Substance and unlawful acts. The third was charged with possession of a Scheduled II Controlled Substance and unlawful act, according to the officials. Both are felonies.

The girl who took the Srattera pill and got sick was taken to the hospital by her grandparents and released afterwards.

Concerta is a prescription stimulant which is commonly used to treat ADHD, daytime drowsiness symptoms of narcolepsy and chronic fatigue syndrome. It was also used to treat cancer-related fatigue. Methylphenidate, the main substance contained by the drug, is a central nervous system stimulant; it reduces impulsive behavior and facilitates concentration at work. Strattera was tested and approved as an ADHD treatment and it is classified as a norepinephrine (noradrenaline) reuptake inhibitor. Many doctors prescribe it in cases of dyslexia, clumsiness and schizoaffective disorder.
