A substance use disorder is when a person keeps using a substance despite physical, emotional, or social problems. The substance can be illegal drugs like cocaine, ecstasy, GHB, or heroin, marijuana, or prescription medicine. People may also misuse chemicals like inhalants.
The cause is not known. Things like genetics, the environment, and peer pressure may play a role.
Drugs stimulate unnecessary chemical release in the brain. Long-term drug use may change brain function.
