Drugs are substances that can affect the body's natural chemicals, called neurotransmitters, which are responsible for controlling mood and behavior. Examples of drugs include illegal drugs like heroin and cocaine, as well as prescription drugs, alcohol, nicotine and other chemicals. The effects of drugs can range from mild to severe, and short term to long term.
