According to Brian Krans, "Drug addiction is a component of drug use disorder. It’s a disease that can affect your brain and behavior, making it difficult to control your use of drugs. Some people become addicted to illicit recreational drugs, such as cocaine or heroin. However, it’s also possible to become addicted to medications that your doctor has prescribed. If you become addicted to a prescription drug, you may compulsively use it, even when it causes you harm."
