 SSPBF2: The
student will compare
different states of consciousness.
 d. Analyze the physical and
psychological issues associated with
addiction.
 e. Explain how the major drug classes
(stimulants, depressants, and
hallucinogens) affect neurotransmission
and behaviors.
 What
are the various types of drugs and
how do they affect neurotransmission?
 Psychoactive
drug –
chemical substance
that alters
perceptions, mood or
behavior.
 These substances can
induce an altered
state of consciousness.
 Include everything
from caffeine to crack
cocaine and LSD.
Dependence – state of
physiological and/or
psychological need to
take more of a
substance after
continued use.
 Not necessarily
addiction. Addictions
interrupt a person’s
ability to function in
day-to-day life.

Withdrawaldiscomfort and
distress that follows
when a dependent
person discontinues
the use of drug.
 Tolerance – reduced
responsiveness to a
drug, promoting user
to increase dosage to
achieve desired
effect.

 Recall
the process of neurotransmission.
 Psychoactive
drugs get into your
synapses and affect neurotransmission in
three different ways.
 1. Binding with receptor cells – mimics a
neurotransmitter’s effects
 2. Blocking receptor sites – prevents
neurotransmitters from binding
 3. Blocking neurotransmitter reabsorption
– intensifying the effects of
neurotransmitter
 According
to the text, there are five major
drug categories.
 On a separate sheet of paper, I want you
to write what you already know about:
 1. depressants
 2. opiates
 3. stimulants
 4. hallucinogens
 5. marijuana
 Either
alone or in pairs, you are to complete
a brochure discussing the 5 classes of drugs
and how each class uniquely affects
neurotransmission.
 Please also elaborate on specific types of
drugs that comprise each class and other
relevant information you acquire from your
text.
 Make the brochure informative and
interesting.
 Avoid including insignificant details and put
brochure IN YOUR OWN WORDS!
