What are Stimulants?

Stimulants are a class of psychoactive drugs that increase alertness.

Stimulant Use Disorder (StUD)

StUD is a diagnosis under the broader category of SUD, which is a chronic, relapsing brain disease characterized by compulsive drug seeking, despite harmful consequences. It is considered a brain disease because drugs change the brain - they change its structure and how it works. These brain changes can be long lasting and can lead to harmful behaviors. SUD or addiction is a lot like other diseases, such as heart disease. Both disrupt the normal, healthy functioning of the underlying organ, can have serious harmful consequences, and are preventable and treatable, but if left untreated, can last a lifetime.

Common Stimulants

Methamphetamine (Meth)
An illegal, highly addictive powerful stimulant. Common names include crystal, ice, and crank.

Cocaine
An illegal drug made from coca plants, usually seen as white powder or crack rock.

Prescription Stimulants
Medications like Adderall and Ritalin, which are used to treat ADHD.

MDMA
A lab-made (synthetic) drug similar to stimulants like methamphetamine. Commonly known as ecstasy or Molly.
