For people diagnosed with attention-deficit hyperactivity disorder (ADHD), Adderall helps to improve concentration and focus. As a central nervous system stimulant it can also have the very same effects on people without ADHD.

If you take Adderall for ADHD, or for other purposes, it’s important to be aware of the side effects. Effects can be positive when Adderall is taken as intended, but for people without ADHD who use the drug without medical supervision, the effects can be dangerous.
