SUCCESS AND LIMITATIONS OF METHADONE AND DRUGFREE

TREATMENT

By Martien Kooyman M.D., Ph.D.

In this presentation I shall try to give an overview of the success and limitations of methadone and drug- free treatment.

Several years ago I attended a conference on drug treatment in Slovenia. I had never before been at a conference where there were so many pharmaceutical companies present advertising their products. During another conference, a Russian psychiatrist said to me: “If we can prescribe methadone to addicts they will stop injecting themselves and then we can stop the AIDS epidemic”. In view of my previous experiences, I had to disappoint him.

When I started my work in the drug field in 1969, I was the medical director of the methadone maintenance program in the Hague. The social worker of this program was very good at finding jobs for our clients. Our clients however, were very successful at getting fired either by coming to their work late or not coming at all. Only after we had introduced urine controls did I discover that all of our clients were also using other drugs such as amphetamines and even opiates in addition to their methadone. I also learned at that time that detoxification in a hospital or admission to a psychiatric hospital for a few weeks without sufficient aftercare was a waste of time.

After I had seen a play in a theater in The Hague performed by residents of a therapeutic

Community in New York called Daytop Village, (this was the first time that I had seen ex-addicts performing), I realized then that treatment of drug addiction was possible. On 14 February 1972, I started the Therapeutic Community Emiliehoeve, the first drug- free therapeutic community on the mainland of Europe. After the first months of chaos struggling with a democratic system, we learned that a stricter structure for residents was necessary. Gradually with the help of American consultants, we introduced the methods and concepts of the American Therapeutic Communities (De Leon, 2000). ’ Parnassia’ is now the name of the umbrella organization for Mental Health and Addiction in The Hague. Within this organization, as well as the Emiliehoeve, a detoxification centre, a therapeutic community for adolescents Mistral, a therapeutic community for ex-prisoners and older addicts, Triple-ex, a program for addicted mothers and children, Project 4 and a methadone program were created

The Emiliehoeve became the role model for many other programs.

In Europe today, there are between 50,000 and 55,000 persons in treatment in therapeutic communities (Kooyman, 2001).

Many politicians thought that all addiction problems could be solved by treatment alone, but not all addicts entering a therapeutic community can be successfully treated. It also takes some time before the addicts decide to enter a treatment program. Addicts did however enter into a methadone program more easily, but most of them also continued to use drugs.

As doctors usually found it hard to exclude them from the methadone program, the urine controls were finally stopped and the clients were kept in the program in the hope that they would then steal less.

These methadone subscription programs differ from the original methadone maintenance

programs in which methadone is given as a substitute drug and clients are excluded when they do not stop their abuse of other drugs.

These programs were later called harm reduction, programs in which methadone was distributed to addicts without any further treatment. Many politicians in Europe saw this as a cheap answer to the drug problem.

Today in the Netherlands, we have heroin distribution in addition to methadone distribution, as it was found that methadone clients did not steal any less. The clients of the heroin prescription programs cost 16.00 Euro per client a year. The clients seem to steal on average three times a month instead of twelve times a month when they are on methadone alone.

Some years ago in the Netherlands, a two-year enforced treatment in prison was introduced for addicts who have been arrested more than three times. The main positive outcome of the system is that the addicts are off the streets for two years, and this keeps the shopkeepers happy. As the quality of the treatment offered in prison is poor, most addicts relapse after their discharge.

Some of the people I spoke to in other countries were surprised to hear that we have involuntary treatment for addicts in this country. The Netherlands seems to be a tolerant country: you can use drugs, buy cannabis in a coffee shop, visit prostitutes, commit suicide and adopt a child as a homosexual couple.

However, the tolerance ends when you steal or are in other ways a nuisance to other people.

What do we know of the success and limitations of methadone and drug free therapeutic communities?

The method of distributing methadone daily to substitute heroin was developed in the United States by Dole and Nyswander. They considered heroin addiction to be a metabolic disease. (Dole and Nyswander,1967). The treatment was called methadone maintenance treatment.

Although methadone prescription was highly criticized, - some therapists called the large scale and life-long prescription of methadone the greatest social crime ever committed (Casriel and Bratter, 1974, Bratter and Pennacchia,1978) - and although forbidden in most countries, it was introduced in many other countries. In the Netherlands it was prescribed to opium addicts from as early as 1968, long before heroin was used by addicts. Heroin appeared on the black market in The Netherlands for the first time in 1973. In Britain, the clinics subsequently stopped prescribing heroin in favour of oral methadone, as it was easier to administer with an oral dose once a day. (Woodcock, 1980, Hartnoll c.s., 1980).

Ten years after they had introduced methadone, Dole and Nyswander admitted that taking methadone without receiving any further support was not sufficient to rehabilitate addicts. (Dole and Nyswander, 1976).

It became clear that the use of heroin or other drugs was not an illness in itself, but a symptom of an underlying problem. It was also evident that not everyone who uses heroin becomes addicted. Almost all heroin addicts used cannabis before they started to use heroin, almost all users of cannabis smoked tobacco previously; but not all tobacco smokers start to use cannabis, not all cannabis users start to use heroin and not all heroin users become addicted.

In the families of addicts, we often find traumatic situations in the families of origin such as incest, suicide, sudden death of a parent, admission to psychiatric hospitals and divorce (Aron, 1975). In a survey in the United States among 732 patients in treatment for drug addiction it was found that 55% of the woman and 29% of the men had had incest contacts (Glover c.s.,

1996). In a study of street addicts in Rotterdam who were using hard drugs, it was found that two-thirds had suffered from serious deprivation in their childhood (Prins,1995). Traumas in adulthood can also lead to addiction. (Kooyman,1999).

The use of drugs, alcohol or medicines to alleviate the psychological pain of traumas can subsequently become a problem in itself.

So, what is addiction?

In my opinion, addiction can be seen as an adjustment to exceptional circumstances by means of adaptive behaviour that has become uncontrollable. Addiction can arise when control over this behaviour is lost. Addiction is no more of an illness than fever, although someone who is addicted can be considered as being ill.

The definition of addiction which follows from this is : Addiction is a self-continuing harmful process resulting from the loss of control over adaptive behaviour which then itself becomes a problem. (Kooyman, 1993, pag.46).

Addiction to drugs can be seen as follows :

A person is faced with a great problem.

He takes drugs and therefore no longer feels the pressure of the problem.

Instead of drugs methadone can be given.

The problem remains unsolved.

Instead the person could learn to ask for help in solving the problem and learn how to solve it with the help of others.

This is the aim of the drug free treatment.

To give you some insight into what happened in The Netherlands, the following personal experiences may illustrate the course of events that took place. I hope that the mistakes that were made in the Netherlands can be avoided in your country.

As I mentioned earlier I was the director of the second methadone program in the Netherlands in The Hague from 1969 onwards.

After I had started the therapeutic community Emiliehoeve in 1972, I remained head of the methadone program and could successfully refer patients from the methadone program who were not able to stay clean from other drugs to this drug- free therapeutic community called Emiliehoeve. If the patients of the methadone program relapsed regularly into taking other drugs, then the methadone distribution was stopped unless they agreed to attend the daily introduction meetings for the therapeutic community or the drug- free day centre. Surprisingly, almost all of them entered the drug- free treatment after some weeks.

This situation remained until 1976, when politicians in The Hague, out of fear for the increasing number of black addicts, mainly immigrants from the former colony of Suriname, decided that methadone should be made available to these addicts even if they continued to use illegal drugs.

A group of Surinam addicts had squatted in a house in which heroin was being sold. The city authorities made a deal with them that they would provide methadone to them if they would leave the house. The addicts left the house, got their methadone and then squatted in another house.

This methadone distribution program was established separately from the existing methadone maintenance program and was run by the City Public Health Department. At first this programme was limited to black addicts only. Several months later after protests from white addicts stating that they were being discriminated against, it was open to all addicts. (Kooyman, 1984). In order to avoid problems with residents protesting about having a centre in their neighbourhood, the methadone was distributed from a special bus at several stops.

The aim of this programme was to try to normalize the life of the addicts in the hope that they would steal less. Soon other cities such as Amsterdam followed the The Hague model. (van Brussel,1987).

These programs for distributing methadone without any demands on the part of the patients became later known as “harm reduction programs” as opposed to methadone maintenance programs where the aim is the substitution of heroin for methadone.

The black market in the Netherlands did not disappear as a result of prescribing methadone on a large scale to all addicts who requested it. As well as this, most addicts were poly drug users. In a study, it was found that more than 60% of the clients of the Amsterdam City methadone distribution program were using cocaine daily. The addicts were usually given low doses of methadone as they preferred it that way, so they did not lose the effect of the heroin they were continuing to take.

It is often overlooked that heroin use is usually only one of the aspects of deviant behaviour.

Research in the Netherlands showed that 50 % of heroin addicts were involved in criminal behaviour before they used their first drug. (Jansen and Swierstra, 1983).

Because heroin is illegal there is a black market for it. The high prices of the drugs lead to theft and other criminal behaviour in order to obtain money. The drugs sold are not pure and may be mixed with substances which cause health risks. It is questionable whether prohibition solves more problems than it produces.

The nuisance which is caused to society by drug addicts leads to reactions expressed by politicians, such as :

Drug addicts should not harm or be a nuisance to others so we should:

- Lock them up

- Supply free drugs

- Force them to give up

- Shoot them ( as they did in Red China - solving their drug problem by executing all addicts who did not succeed in giving up )

A more humane reaction is :

All addicts should receive treatment

Methadone seems to be an instrument to reach all addicts.

It is however questionable, that if methadone distribution reduces the nuisance to society does it reduce crime.

The Scientific Institute of the Ministry of Justice carried out research to study the effect on the reduction of crime of the Amsterdam City methadone distribution programs.

Three groups of addicts were compared :

-A group from a low threshold program where methadone was obtained from a bus without further demands.

- A group from the high threshold program where the person was offered other services in addition to methadone and where urine checks were mandatory.

- A group not receiving any methadone

The results of this study were (See table 1):

The people in the high threshold programs were least involved in criminal activities ( 60 % not involved ). Surprisingly, the clients from the low threshold programs did worse than those who did not receive methadone at all ( 33% as opposed to 41% who did not get involved in crime ).

Furthermore: The clients of the low threshold or harm reduction program profited more from their crimes and were involved in more complex criminal activities than those from the other groups as can be seen in table 2 (Leuw, 1998).
