Society’s most common, serious &
neglected problems.
1 in 4 Canadians will experience addiction or
mental illness during their lifetime (1/10 in a year).

determined
is an evolving concept within our
society

17
Current concepts in understanding
meaning of “substance abuse” and
“addiction”
Physical dependence
Drug tolerance
Withdrawal
Psychological dependence
Harm
18
Physical Dependence
state in which the body has adapted to
the presence of the drug at a particular
level
when the drug concentration falls,
withdrawal results
19
PHYSICAL DEPENDENCE
Tolerance
the need for an increased amount of a given
drug to achieve intoxication or desired effect
or the reduction of a drug’s effect with
continued use of the same dose over time
20
PHYSICAL DEPENDENCE
Withdrawal
Occurs when a drug is abruptly
removed, or dose is significantly
decreased
Cluster of symptoms often accompanied
by directly overt physical signs
21
Withdrawal ...cont’d
Withdrawal generally looks opposite to
the intoxication.
Unpleasantness of withdrawal may be
so severe that the individual fearing it
may use drug again just to avoid or
relieve symptoms
22
Psychological Dependence
a state in which stopping or abruptly
reducing the dose of a drug produces
non-physical symptoms
characterized by emotional and mental
preoccupation with the drug’s effects
and a persistent craving for the drug
23
Harm
Central concept in understanding both
addiction and substance abuse
Types of harm:
Physical
Psychological
Social (e.g., family, friends, job, financial,
legal system)
Spiritual
24
Abbreviated List of Criteria for Abuse and
Dependence
Preoccupation with substance
Increased use of substance beyond expected
Inability to control use
Withdrawal symptoms
Signs of tolerance
Restricted activities
Impaired functions
Harmful or hazardous use
25
DSM IV Definitions
DSM IV
Substance Dependence
At least 3 within a 12-month period:
Tolerance
Withdrawal
Unintentional Overuse
Persistent desire or efforts to control drug use
Reduction or abandonment of important
social, occupational or recreational activities
Continued drug use despite major drugrelated problems
27
Substance Abuse: At lease one
criterion must apply within a 12 month period
Recurrent use leads to failure to fulfill major
role obligations at work, school, or home
Recurrent use in situations which are
physically hazardous
Recurrent substance-related legal problems
Continued use despite persistent physical,
social, occupational, or psychological
problems
28
Aside from the DSM…“Drug
Abuse” is…
a highly complex, value-laden term that
does not lend itself to any single
definition.
Its meaning differs from one society to
another
29
Review of key points…
Our understanding of the meaning of
addiction is evolving. The current model of
addiction is called the “___________” model.
What are 3 key concepts in our current
understanding of addiction & substance
abuse?
Of these 3 concepts, which one is common to
both substance dependence & substance
abuse?

33
STIGMA, DISCRIMINATION
& ADDICTION
34
What is stigma ?
 A complex idea that involves beliefs, attitudes,
feelings and behaviour.
 Refers to the negative “mark” attached to people
who possess any attribute, trait, or disorder that
marks that person as different from “normal”
people.
 This ‘difference’ is viewed as undesirable and
shameful and can result in negative
attitudes/responses (prejudice and
discrimination) from those around the individual.
35
Stigmatizing language
Addict
Substance “abuse”/abuser
Drunk
Crack-head
Junkie
Others…
36
Legal status of drugs does not
reflect harms
Alcohol and tobacco cause more illness
and death than all other drugs
combined
Consider the ratio of harms to stigma
37

addiction
38
PATTERNS OF DRUG USE
within the population at large
among persons with disabilities
39
79% of general population drink, 14% use
cannabis. (CAS 2004)
18% exceeded drinking guidelines.
14% reported hazardous drinking.
Majority of acute problems are the result of
average drinkers who drink too much on single
drinking occasions. (Rehm 2003)
Alcohol, tobacco and other drugs cost Canadians
over $18 billion annually. (Single, 1996)
40
Over 90% of the alcohol consumed by males aged 15 to
24 years and over 85% consumed by young females
exceeded Canadian guidelines. (Stockwell 2005)
Close to 60% of those between 15 and 24 have used
cannabis at least once; 38% used cannabis in the past
year. (CAS 2004)
Over 80% of Grade 12 students drink and almost half of
these students report hazardous drinking. (Adlaf 2005)
Daily cannabis use has increased significantly and 1 in 5
students report driving after using cannabis. (Adlaf 2005)
Although smoking has gone down, 1 in 7 students still
smoke. (Adlaf 2005)

DRUG EFFECTS
How do drugs work?
What makes one drug more addictive
than another?
Which drugs are creating the most
harm?
75
How Drugs Work
In order to predict the effect of a drug, we need to know:
the type of drug
size of dose
how drug was taken
distribution and absorption
metabolization
interactions
76
Metabolization
blood-brain barrier
body doesn’t distribute all drugs in the
same way
some are stored in fat cells and
released slowly
others bind to plasma protein in the
blood and move to the brain quickly
77
Liver Action
Liver contains enzymes that work to
eliminate the drug from the body.
As the liver breaks down the drug it
forms metabolites - some may not be
psychoactive; others may be more
potent than the original drug.
Metabolites eliminated from the body in
urine or feces
78
Drug Interactions
taking different drugs together creates
new effects that are different than those
from a drug taken alone
known as potentiation, its like multiplying
the effects of two drugs rather than
simply doubling the dose
some drugs cancel the effects of others.
This is known as an antagonist effect
79
Types of Drugs
Classified by Psychoactive Effect
Stimulants
Depressants
Hallucinogens
Antidepressants
Antipsychotics
80
Stimulants
increase activity by stimulating the
central nervous system
reverse the effects of fatigue and
elevate a person’s mood
nicotine and caffeine are the most
common drugs
81
Depressants
slow down body activity by depressing central
nervous system
induce sleep, coma and even death
sleeping pills (barbiturates), tranquilizers
(benzodiazepines), antispasmodics and alcohol
are most common depressants
opiates such as heroin and morphine can be
thought of as a special class of depressants, as
can neuroleptics such as neurontin & gabapentin
82
Hallucinogens
cause user to see hear or feel things that
aren’t there yet without causing serious
disturbances to CNS
LSD (acid), psilocybin (magic mushrooms)
and mescaline are common examples of
drugs
inhalants and marijuana have
characteristics of depressants and
hallucinogens
83
Antidepressants
MAO inhibiters
Tricyclics, such as amitriptyline, Elavil,
imipramine
SSRIs, such as Prozac, Paxil, Celexa, Zoloft
SSNRIs
Others, such as Wellbutrin, Effexor
84
Antipsychotics
Major tranquilizers, such as
chlorpromazine, Haldol
“Atypical” antipsychotics, such as
clozapine, olanzepine, resperidone &
Seroquel
85

88
HARM REDUCTION
89
Drugs Cause Real Harms!
Implicit in the term harm reduction is the
belief that drugs can cause real harms.
These harms are not an inevitable
consequence of drug use, and can be
prevented or ameliorated through a range of
strategies that include but do not invariably
require complete cessation from all drug use
90
Harm Reduction: Key Concepts
Harm reduction aims to reduce the
adverse health, social, and economic
consequences of alcohol and drug use
without requiring abstinence.
Goal is to reduce harms to the
individual and the community.
91
Harm Reduction- Key Concepts
 Focuses on reducing harms and not
necessarily on reducing use
 Accepts that drug use is universal and brings
with it both risks and benefits
 Does not judge drug use as good or bad.


Morally neutral - does not promote use or
condemn use
Non-Coercive
92
Harm Reduction: Key Concepts
 Acknowledges that quitting drug use
may not be realistic or desirable.
 Provides practical strategies
 Public health
 Human rights approach
 No person should be denied access to
services because of their drug use.
93
Harm Reduction: Key Concepts
Hierarchy of Goals instead of one all or
nothing decision.
Balances Costs and Benefits
Provides accurate information.
Attempts to promote & facilitate access to
care for addiction & mental health problems.
Engage drug users in a continuum of care
from which they would otherwise be excluded
94
Harm Reduction & Abstinence
Non-use is a viable choice
Can described as overlapping elements
within a continuum of care.
Drug holiday – short-term abstinence
Abstinence from one drug but not all drugs
Long-term abstinence from all drugs.
Abstinence as the goal, but harm reduction
strategies used if one relapses.
