In 2008, one study stated that 2.5 million people were prescribed Adderall annually. A few years later, in 2012, that number rose to 16 million prescriptions just for individuals aged 20-39. Of course, these numbers aren’t counting the millions of children with Adderall prescriptions or the college kids who love to use this medication illegally. Clearly, Adderall usage has become common and prevalent across the nation.
