Part I
International drug control
Illicit drug use
Worldwide, 2008:
Problem drug users (severely dependent on
drugs of abuse): 26 million1
Injecting drug users: 16 million2

Protection of populations against abuse and
dependence is necessary

International Drug Control
Conventions
●
●
●
Single Convention on Narcotic Drugs (1961)
United Nations Convention on Psychotropic
Substances (1971)
United Nations Convention against Illicit
Traffic in Narcotic Drugs and Psychotropic
Substances (1988)
Conventions' Objectives
1961 and 1971 Conventions:
Two goals:
1.
Prevention of harm from drug dependence
2.
Availability for rational medical use
Public health interests are best served if all
control measures aim at the optimum
between medical availability and prevention
of abuse
Convention principles
1961 and 1971 Conventions:
●
●
Both have 4 lists of substances
"schedules"
Each schedule is related to a set of control
measures
Intermezzo: exclusion of
tobacco and alcohol
"…That problem, however
serious, therefore does not
"warrant" the placing of
tobacco under 'international
control'…"

Controlled medicines on
the WHO EML
– Opioid analgesics:
Morphine
moderate to severe pain
– Long-acting opioid
agonists: methadone,
buprenorphine
treatment of opioid
dependence
– Ergometrine and
ephedrine
emergency obstetrics
– Benzodiazepines
anxiolytics, hypnotics,
antiepileptics
– Phenobarbital
antiepileptic

Drug conventions
Recognizing that the medical use of narcotic
drugs continues to be indispensable for the
relief of pain and suffering and that adequate
provision must be made to ensure the
availability of narcotic drugs for such
purposes …
(Preamble Single Conv. on Narcotic Drugs)
Reasons for low access to
controlled medicines
●
Excessive fear for dependence
●
Excessive fear for diversion
●
Neglected medical needs
Treatment with opioids
a. Pain
Three Step Ladder
WHO Three step ladder on cancer pain (1986)
1.
Non-opioid + adjuvant e.g. paracetamol
If pain persisting/increasing:
2.
Weak acting opioid (e.g. codeine, tramadol)
If pain persisting/increasing:
3.
Strong acting opioid (e.g. morphine, methadone)
Increase dosage until freedom from pain
There is no maximum dose: the right dose
is the dose that works
Opioid analgesics
Used for all moderate to severe pain due to:
• Cancer
• Traffic and other
accidents
• AIDS/HIV
• Myocardial infarction
• Chronic pain
– Some exceptions • Sickle cell anaemia
• Surgery
A myth:
Dependence from opioid analgesics
●
Very low incidence
–
●
●
Many doctors claim dependence from
treatment is non-existent
Withdrawal is unequal to dependence
Pain population very different from heroin
user populations
Treatment with opioids
b. Opioid Dependence
Long-Acting Opioid
Agonist Therapy
●
Methadone Maintenance Therapy (MMT)
–
–
–
●
Supervised administration of Methadone oral
solution
Dosage level high enough to stop heroin use
Continuously
Other modalities (e.g. buprenorphine: BMT)
Long-Acting Opioid
Agonist Therapy
●
●
●
●
To treat opioid dependence (which is a
disease)
Methadone less reinforcing then heroin
Normalization of body responses and
social life
Interruption of transmission of

WHO Programme to
improve access to
controlled medicines
Launched in 2007 by

Access to Controlled
Medications Programme
●
●
●
Addresses all medicines controlled under the
international drug conventions
Essential Medicines in particular
Problems and solutions supposed to be very
similar, giving opportunities
–
for finding allies
–
to prevent double work

Update of WHO Policy guidelines
"Achieving Balance in Nat. Opioid Control
Policies"
Model legislation

●
Situational analysis and drafting a plan
Introduction of balanced policy
–
optimum for accessibility for medical use and prevention of
dependence and abuse
Model plan drafted with involvement of MoH
Ghana, APCA and health care workers
can easily be adapted to local needs elsewhere
Example: analysing barriers

Policy barriers
Regulatory and
administrative barriers
Attitudinal and
educational barriers
Supply barriers
Country support
• Update of national essential medicines list
• Oral morphine
• Oral methadone
• Update of National Medicines Policy Plan
• Training of civil servants
• Estimates/statistics
• Support to health education institutions

adequacy of opioid consumption
• Article on figures for 2006 submitted
