Drugs - presentation

Drugs are chemicals or substances that change the way our bodies work. Some are medicines that help people when doctors prescribe them. Many have no medical use or benefits.
When taken (usually by swallowing, inhaling, or injecting), abused drugs find their way into the bloodstream. From there, they move to the brain and other parts of the body. In the brain, drugs may intensify or dull the senses, change how alert or sleepy people feel, and sometimes decrease physical pain.
