Amphetamines are a group of synthetic stimulants that affect the Central Nervous System. The drugs were originally available over-the-counter, but due to the increase in addiction and abuse of the drugs, the U.S. government now restricts the drugs allowing them to be obtained only through a prescription. Adderall and Ritalin are the most well-known brand name for prescription amphetamines; for a certain generation and a certain age group, these drugs are nearly synonymous with ADD/ADHD (Attention Deficit Disorder/Attention Deficit Hyperactivity Disorder).
Amphetamines typically come in pill form and are ingested orally. However, they are sometimes injected, snorted or smoked in the case of amphetamine abuse. Amphetamine side effects and withdrawals can range depending on the ingestion methods used. In addition to the commonly known Ritalin and Adderall, other brand names for Amphetamines include Desoxyn, DextroStat, Dexedrine, and Benzedrine. Street names for the drugs include white crosses, wake-ups, uppers, speed, pep pills, lid poppers, eye-openers, copilots, black beauties and bennies.
