| 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 pain killer which depresses the Central Nervous System. This produces a feeling of relaxation, security and well being. |

| Medicinal uses |

Heroin was not extensively used in medicine until around the beginning of the 20th 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 replace the opium-based compounds that were used in the past. |

| Abuse of Heroin |
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.
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? |
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 tranquility. 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.
| Consequences of heroin use |
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 writers 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 powerfull 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.
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 painfull 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.
(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.)
