Ritalin®    Ritalin® is a stimulant used to treat Attention Deficit/ Hyperactivity Disorder (ADHD), Attention Deficit Disorder (ADD), and narcolepsy. On the street Ritalin® is known as Vitamin R, Rit, Kibbles and Bits, and Pineapple. When Adderall® is taken by someone without ADHD, ADD, or narcolepsy, it creates a stimulant-like effect, producing focus and alertness. Some demographics prefer to take the drug by crushing and snorting the tablets. In addition to increased focus, the user may also experience dizziness, tremors, severe headache, insomnia, heart failure, fatal seizures, and feelings of paranoia. The drug can have a cocaine-like effect when snorted, and snorting can also burn the lining of the nose. 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.
