Adderall®     Adderall® is a stimulant used to treat Attention Deficit/ Hyperactivity Disorder (ADHD), Attention Deficit Disorder (ADD), and narcolepsy. On the street Adderall® is known as beans, black beauties, dexies, pep pills, speed, and uppers. When Adderall® is taken by someone without ADHD, ADD, or narcolepsy, it causes the user to feel more focused and attentive. The user may also experience dizziness, headaches, irregular heartbeat, hostility, paranoia, or even heart failure or fatal seizures. Long-term use can lead to addiction and compulsive activity. Because most illegal users of Adderall® get the drug from individuals with a prescription, illegal use can be prevented by closely monitoring those with a prescription.
