Amphetamine is a powerful stimulator of the central nervous system. It is used to treat some medical conditions, but it is also highly addictive, with a history of abuse.
Stimulants such as amphetamine (Adderall) and methylphenidate (Ritalin and Concerta) are used to treat attention deficit hyperactivity disorder (ADHD). Used under prescription, stimulants can be safe and effective.
Amphetamine sulphate, or speed, is also used for recreational and non-medical purposes. It can lead to euphoria, and it suppresses the appetite, which can lead to weight loss. Used outside the medical context, stimulants can have severe adverse effects.
