CENTRAL NERVOUS SYSTEM DEPRESSANTS ALCOHOL BARBITURATES ANTI-ANXIETY TRANQUILLIZERS MANY OTHERS
CENTRAL NERVOUS SYSTEM DEPRESSANTS Central Nervous System Depressants slow down the operation of the brain. Depressants first effect those areas of the brain that control a persons conscious voluntary actions. As the dose is increased depressants begin to effect the parts of the brain that control the body’s automatic process. (i.e. heartbeat, respiration, etc.) The CNS depressant category includes the single most commonly abused drug in Canada, alcohol
