Stimulants are a large class of addictive drugs. They work by acting on the central nervous system — forcing it into a state of alertness and often promotes feelings of euphoria.
Stimulant drugs are one of the most highly-abused classes of drugs in the world — especially among teens and young adults.
Students and young adults are using these drugs to improve productivity and increase academic performance. Unfortunately, many of these people are becoming addicted to these drugs over time — eventually seeking stronger, illicit drugs as tolerance increases.
Illicit drugs like crack, cocaine, methamphetamines, MDMA, synthetic cathinones (bath salts) are all highly addictive, schedule I stimulants.
Pharmaceutical stimulants are also often abused, which can lead to addiction and often lead people into using illicit stimulants when their prescription runs out or becomes too expensive. Examples of pharmaceutical stimulants include Adderall, Ritalin, modafinil, and Vyvanse.
