What is it?
Heroin is an opiate. Pure heroin is a white powder with a
bitter taste, which is made from the milky ‘sap’ of the opium poppy (see
right). This plant is grown as an illicit crop in countries across the Middle
East, Asia and South America.
Heroin is a
powerful painkiller, which depresses the Central Nervous
System. This produces a feeling of relaxation, security and well
being.
Medicinal uses
Although opium has been known and used as a sedative and
intoxicant in some cultures for several thousand years, heroin is a relatively
new substance. It was first synthesized from morphine in 1874 in Germany and
given the name heroisch - meaning ‘powerful’.
Heroin was not extensively used in medicine until around the
beginning of this century. At that time it then received widespread acceptance
from the medical profession as a sedative and anaesthetic as shown by the
poster at right. Physicians remained unaware of its potential for
addiction.
When the dangers of heroin came to be appreciated many
governments around the world took steps to control its manufacture and it came
under very strict prescription controls.
Today heroin does not have many legitimate medical
applications, as synthetic sedatives and anaesthetics have replaced the
opium-based compounds that were used in the past.
Abuse of Heroin
Illicit heroin comes in the form of a powder which may vary
in colour from white to dark brown because of impurities left from the
manufacturing process or the presence of adulterants. The powder can be sniffed
or dissolved in water and injected. It can also be smoked by mixing with
tobacco or heating on tin foil and inhaling the fumes, or swallowed after being
wrapped in paper.
Heroin on the streets is usually diluted with other
substances - ranging from lactose to paracetemol. However, the amount by which
the drug is ‘cut’ varies from purchase to purchase or day to day and so its
purity in any particular locality can vary enormously - depending pretty much
on the mood of the dealers. Many deaths have resulted from overdosing on a
batch of unusually pure heroin.
A few years ago powders sold as illicit heroin only actually
contained 1 to 10 percent of the drug. In recent years street supplies have
become stronger and the UK national average purity of heroin is now around 40
percent, although it can range from 1 to 98 percent (hence the likelihood of
accidental overdose).
Along with an increase in purity, the cost of heroin has
fallen. A gram of the drug now costs around 60 Pounds Sterling on the
street.
Until recently, most heroin users took the drug by injection
- either into a vein, under the skin or into a muscle. This is the most
practical and ‘efficient’ way to take impure heroin.
The availability of higher purity heroin has meant that more
users can now snort or smoke the drug and still achieve the desired effect.
Smoking and sniffing of heroin appears to be on the increase in the UK as of
1997/8.
Although this may seem like ‘good’ news, as sniffing or
smoking heroin eliminates the health risks associated with injecting drugs, it
has a downside. Many people may try heroin by sniffing or smoking it, who may
not have tried the drug if they had to inject it.
Sniffing or smoking heroin is likely to be more appealing to
new users because it eliminates both the fear of acquiring syringe-borne
diseases such as HIV/AIDS and hepatitis, and the initial distaste regarding
self-injection.
It would certainly be a cause for concern if the reduction in
the cost of heroin and increase in its purity leads to the drug becoming more
acceptable to young people.
What effect does it have?
All opiates tend to relax the user and kill pain to some
degree. Heroin is the most powerful opiate and when it is injected, the user
feels an immediate ‘rush’ of relaxation and well-being. Physical pain is
completely removed - and so is emotional pain.
It can be hard for non-users to understand the attraction of
drugs - particularly heroin - but a major reason why any individual may feel
drawn to use heroin again after an initial experience is that it produces such
a powerful sense of security and tranquillity. It produces a state of mind
where all cares and worries seem far removed. Nothing matters. Perhaps it’s
like being in the womb.
The best description this writer has ever found is:
“But with heroin, ahhh. You can just sit in a sewer all day
and be soooo happy and feel soooo good”
(“Junk” - Melvin Burgess, 1996 Penguin Books)
Of course, these pleasant sensations have nothing to do with
reality. No matter how good a user may feel, the reality is the sewer - or
whatever other situation exists - and this is usually quite unpleasant - hence
the need to escape from it.
Side effects from heroin use - particularly for new users -
include restlessness, nausea and vomiting. The user may go ‘on the nod’ or
‘gouch out’ - going back and forth from appearing fairly alert to almost
falling asleep. The pupils of the eye are reduced to pinpricks.
Tolerance
If heroin is used regularly over a period of time then a
tolerance to the drug builds up. It makes no difference what method of taking
heroin a person may employ - and regularly can mean using many times each day,
or only two or three times each week.
Users have to take larger amounts of heroin in order to get the same effect as
previously. Tolerance can build up quite quickly - over a matter of weeks -
although it continues to increase as long as a user takes heroin regularly.
If a person is abstinent from heroin for a time, their
tolerance to the drug decreases. If they should use heroin again in the same
amounts as previously, an overdose could easily occur.
Consequences of heroin use
Risks to physical health
One of the most obvious risks of taking heroin is that of
overdose. This can occur whatever method is used to take the
drug, although intravenous injection is most dangerous in this respect as the
whole dose is delivered directly into the blood system.
Heroin is a Central Nervous System depressant and when it’s
taken vital functions such as higher brain activity, breathing and heart rate
are inhibited - or slowed down. If a large dose is taken - or the heroin is
exceptionally pure - the user may become comatose and the skin feels cold and
clammy. Breathing becomes shallow and intermittent and death may occur.
Other physical health risks related to heroin use are
associated with the means of taking the drug. Users who inject heroin might
often employ contaminated needles or syringes. This can lead to severe blood
infection and damage the heart.
In case anyone thinks this is a joke, it’s how this
writer’s best friend died. He (my mate Keith) got septicaemia from an
unsterile needle. This damaged the valves of his heart and he nearly died
shortly after. He had to have operations to put in plastic heart valves and a
pacemaker. He lived for a few years after that but then his heart gave out.
That’s reality.
Injecting heroin - or any drug - in situations where shared
needles are used, perhaps accidently, leaves the users open to infection from
the HIV virus that causes AIDS. Hepatitis B or C, both of which are serious
infections, can be spread in this way and are common among intravenous heroin
users.
Another immediate physical danger associated with heroin use
exists if the drug is combined with other substances. Other depressant drugs,
such as alcohol, benzodiazepines and barbiturates are particularly dangerous as
they are all CNS depressants. As heroin is also a powerful CNS depressant, the
combined effect of mixing these drugs can depress breathing or heart rate to
such an extent as to cause respiratory failure or heart failure.
Dependence
Physical and psychological dependence upon heroin is likely
to occur, especially if a person uses a lot of the drug or even uses it
occasionally over a long period of time. The method of taking heroin makes no
difference here - a person who sniffs or smokes heroin can become dependent on
the drug just as easily as a person who injects it.
Heroin use can result in a powerful physical addiction.
Coming off the drug can be very difficult because withdrawal
symptoms - although lasting for only a few days - are fairly severe. Abstinence
can bring on symptoms such as chronic diarrhoea, muscle cramps, vomiting,
insomnia, sweating, anxiety, and tremors. The prospect of going through such a
painful withdrawal puts many heroin users off the idea of trying to stop using
the drug.
Once the physical withdrawal is over, a craving for the drug
may still persist for a long time and relapses are common. Generally speaking,
a heroin user who wishes to stop using the drug completely needs a strong
support network to help him or her overcome the craving for the drug.
Social consequences
It costs a lot of money to maintain a regular intake of
heroin. Many regular users resort to crime of one kind or another to fund their
drug use. This has serious implications for our society, as the social costs of
drug-related crime are enormous. An estimate of the size of the problem was
provided in research by the UK Home Office in 1997, which found that 20 percent
of all people arrested in Britain were on heroin.
Effect on pregnant women
Researchers estimate that nearly half of the women who are
dependent on heroin suffer anaemia, heart disease, diabetes, pneumonia, or
hepatitis during pregnancy and childbirth. They have more spontaneous
abortions, breech deliveries, caesarean sections, premature births and
stillbirths.
Infants born to these women often have heroin withdrawal
symptoms, which may last several weeks or months. Many of these babies die.
Legal consequences
Heroin is a Class A drug. It is illegal to supply or possess
it. Penalties are high.
(Drugs similar to heroin, such as morphine, opium, methadone,
dipapanone and pethidine are also Class A drugs. Codeine and dihydrocodeine
(DF118) are Class B drugs unless they are prepared for injection when they
become Class A drugs.)
