Adderall is a medicine made by anphetamines, it is effective in treating the symptoms of ADHD and narcolepsy. At therapeutic doses, Adderall causes emotional and cognitive effects such as euphoria, increased wakefullness, and improved cognitive control. At these doses, it induces physical effects such as a faster reaction time, fatigue resistance, and increased muscle strength.
Recreational use of Adderall generally involves far larger doses and is therefore significantly more dangerous, involving a much greater risk of serious adverse drug effects than dosages used for therapeutic purposes, such as, cardiovascular accidents (heart attack and strokes), apetite loss, risk of seizures and psychosis, specially when this substance is abused.
