BUFFALO, NY (WKBW) - College students are taking a "smart pill" to help them cram for exams.

Adderall is a legal prescription drug used to treat Attention Deficit Hyperactivity Disorder or ADHD.

But students who do not have the disorder are taking the drug anyway.

Students like Kayla Small. The University at Buffalo student has a doctor's prescription for Adderall.

"It helps me focus on my school work. Completely. If I didn't take it I wouldn't be going to school here anymore," she said.

Small does not have ADHD or any other disorder. She is among a growing number of college students who use Adderall to give them a competitive edge, especially during finals week.

"I can stay on my work and not have to think about anything else," Small said. "My mind will wander if I'm not on it."

There are currently no major studies on Adderall use by college students, but addiction specialist Kathleen Miller said it is growing.

"About six to seven percent of college students are users of Adderall or Ritalin or other ADHD drugs non-medically," Miller said.

Small said the number is actually much higher.
