Adderall is a prescription medication that contains amphetamine and dextroamphetamine. It is commonly prescribed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Adderall works by increasing the levels of certain chemicals in the brain that play a role in attention and impulse control. It's important to note that Adderall should only be used under the supervision of a qualified healthcare professional. It is not intended for recreational use or for enhancing cognitive performance in individuals without ADHD.
