amphetamines

Amphetamines are a group of central nervous system stimulants that are commonly used to treat conditions such as ADHD and narcolepsy. They work by increasing the levels of certain neurotransmitters in the brain, resulting in increased focus, attention, and alertness. Amphetamines have a high potential for abuse and dependence and are classified as a Schedule II controlled substance in the United States. Some common examples of amphetamines include Adderall, Vyvanse, and Dexedrine.
