What are psychoactive drugs?
“…Any chemical substance which, when taken
into the body, alters its function physically and/
or psychologically....”
World Health Organization, 1989
“…Any substance people consider to be a
drug, with the understanding that this will
change from culture to culture and from time to
time.”
Krivanek, 1982

What are psychoactive drugs?

nervous system (CNS) affecting:
►Mental processes and behaviour
►Perceptions of reality
►Level of alertness, response time and perception
of the world

Why do people initiate drug use?
There is a believe that drug use is
motivated (at least initially) by the
pursuit of pleasure. However,
according to scientific evidence, there
are factors such as exposure to abuse,
neglect, violence, etc., especially in
childhood, leading to vulnerabilities to
initiate drug use.

What is drug addiction?
Drug addiction is a complex illness characterised by
compulsive and at times, uncontrollable drug craving,
seeking, and use that persist even in the face of
extremely negative consequences.
(NIDA, 1999)
Substance dependence is not a failure of will or of
strength of character but a medical disorder that could
affect any human being. Dependence is a chronic and
relapsing disorder, often co-occurring with other physical
and mental conditions."
(WHO, 2004)

Characteristics of drug addiction
►Compulsive behaviour
►Behaviour is reinforcing (rewarding
or pleasurable)
►Loss of control in limiting intake

Important terminology
►Psychological craving
►Tolerance
►Withdrawal symptoms
![Page 23: Elements of Psychological Treatment - unodc.org · Drug addiction is a complex illness characterised by compulsive and at times, uncontrollable drug craving, seeking, and use that](https://reader030.fdocuments.us/reader030/viewer/2022040712/5e152cd80d39cb05ed22dc5c/html5/thumbnails/23.jpg)
23
Psychological craving
►Craving refers to the desire or urge to re-experience
the effect of a previously experienced psychoactive
substance
► It is often described as the subjective experience
(psychological) of the motivational state that increases
the likelihood of drug use (although it is not directly
responsible for it)
►Cravings are most apparent during drug withdrawal
and when exposed to triggers
![Page 24: Elements of Psychological Treatment - unodc.org · Drug addiction is a complex illness characterised by compulsive and at times, uncontrollable drug craving, seeking, and use that](https://reader030.fdocuments.us/reader030/viewer/2022040712/5e152cd80d39cb05ed22dc5c/html5/thumbnails/24.jpg)
24
Psychological craving
Craving can also be described as the
conscious/subjective experience of the following:
►Feelings of urge
►Physical/physiological sensations (heart rate increase,
perspiration, etc.)
►Actual temptation
►Uncontrollable thoughts
![Page 25: Elements of Psychological Treatment - unodc.org · Drug addiction is a complex illness characterised by compulsive and at times, uncontrollable drug craving, seeking, and use that](https://reader030.fdocuments.us/reader030/viewer/2022040712/5e152cd80d39cb05ed22dc5c/html5/thumbnails/25.jpg)
25
Psychological craving features
►Craving tends to be highly associated with the context
►Triggers are stimuli previously associated with drug
use:
– people
– places
– paraphernalia
– money
– certain days of the week, etc.
►Craving can persist far beyond the cessation of drug
use
![Page 26: Elements of Psychological Treatment - unodc.org · Drug addiction is a complex illness characterised by compulsive and at times, uncontrollable drug craving, seeking, and use that](https://reader030.fdocuments.us/reader030/viewer/2022040712/5e152cd80d39cb05ed22dc5c/html5/thumbnails/26.jpg)
26
Psychological craving
Psychological craving is a complex phenomenon
►Craving report and drug use is not as tightly related as
initially thought
►Craving report and cue reactivity (heart rate, sweat-
gland activity, blood pressure, temperature, etc.) don’t
show a systematic co-variation among studies
►More research is needed to clarify this complex
phenomenon in order to improve treatment programs
![Page 27: Elements of Psychological Treatment - unodc.org · Drug addiction is a complex illness characterised by compulsive and at times, uncontrollable drug craving, seeking, and use that](https://reader030.fdocuments.us/reader030/viewer/2022040712/5e152cd80d39cb05ed22dc5c/html5/thumbnails/27.jpg)
27
Tolerance
Tolerance is a state in which a person
no longer gets the expected responses
from a drug as it was experienced
before. A higher dose is now required
to achieve the same effect.
![Page 28: Elements of Psychological Treatment - unodc.org · Drug addiction is a complex illness characterised by compulsive and at times, uncontrollable drug craving, seeking, and use that](https://reader030.fdocuments.us/reader030/viewer/2022040712/5e152cd80d39cb05ed22dc5c/html5/thumbnails/28.jpg)

Withdrawal symptoms
Physiological reactions that occur
when after a period of using a drug
this habit is discontinued. The
reaction could be mild e.g., tobacco to
life threatening e.g., alcohol.

Classifying psychoactive drugs

effects of drugs. It is intended as a general guide to better
understand relative drug effects, harms and potential
withdrawal features.
Variations in effects and intensity for drugs in the same
category may occur for drugs within the same class.

32
Classifying psychoactive drugs
• Slow down the CNS and body functions, such as heart rate, breathing, blood pressure, etc. and behaviour e.g., slow/uncoordinated movements, slurred speech, etc.
Depressants
• Speed up the CNS and body functions. It can be noticed on mood – happy, excited, euphoria; cognitive performance – better concentration, increased alertness; and behaviour – insomnia, fast movements/speech, etc.
Stimulants
• Alter states of perception and feelings, there are 3 types. Psychedelics: feeling new ways of relating with their inner mind. Dissociative: feelings of being separated from one’s body and environment. Delirants: confusional state and problems to focus attention.
