Depressants are drugs that affect the central
nervous system. This drug when ingested, breaks down inside the body and is
absorbed in the bloodstream, which then travels to the brain. As a result motor
skills of a person are affected. These are commonly prescribed by psychiatrists
who treat patients that have obsessive compulsive behaviors. It is also usually
administered to patients in mental clinics to suppress their aggressive and
destructive behaviors.
