Module 3
Uppers and Downers
Drugs affect the central nervous system in many ways. Stimulants, or uppers , like cocaine and speed, may make the user feel more energetic or talkative. Thus, stimulants excite the central nervous system. In contrast, downers such as heroin, benzodiazepines, inhalants, or barbiturates, may create a mellow or calming effect, or inhibit the central nervous system.
