by influencing their mood, their sensations, or their muscular coordination. These chemical, mind altering

substances are known as psychoactive drugs (PaD). These PaD, depending on their cultures, were

used for religious rituals to control pain, or to raise ones energy during warfare. As time went on, more

and more people became aware of these substances and a familiar pattern started to form. People began

using these chemical substances for pleasurable experiences.

How do drugs work? For a drug to affect our behavior it has to get into our blood stream through

ingestion, inhalation, absorption through the mucous membrane of the mouth or nose, or injection with a

hypodermic needle. Once the PaD are in our bloodstream it starts to influence our behavior

by altering the functioning of our central nervous system (CNS). After a period of hours, the drugs

influence gradually wears off as the liver produces enzymes that metabolize the drug.

Most PaD can be categorized into two major groups, stimulants (which enhance the

activity of the CNS) and depressants (which slow down the activity

should also bring to your understanding how drugs affect our neurotransmitters. Drugs that mimic or

depresses the functioning of the CNS, impairing memory, concentration, and muscular coordination.
