Drug addiction, gambling addiction, internet addiction, sex addiction......
"Addiction" sounds like a scientifically justified diagnosis describing a pathological process. But does the term really represent an increased insight over the popular synonyms like to "be hooked on" something?
The word "addiction" seems to have got its current meaning through AA's theory of alcoholism. When epidemiological and experimental research had removed the basis for AA's alcoholism theory, WHO choose in 1979 - as a compromise - to replace it with "alcohol addiction syndrome". The usual interpretations show that many of the implications of the alcoholism theory now live on under the name "the addiction syndrome".
The diagnosis of addiction
The official diagnosis systems ICD and DSM currently have identical criteria for addiction to alcohol, illegal drugs and tobacco. Addiction to gambling, sex, internet etc are not mentioned, but psychologists who care about these addictions obviously use equivalient definitions.
The diagnosis systems mention 6-7 possible symptoms which can be classified into three groups:
- increased tolerance and/or abstinence problems
- signs of loss of control (strong craving/ compulsiveness or drinking more than planned or failed to cut down on use)
- damaging effects (social, health or work-related)
Currently no "symptoms" are mandatory. The addiction diagnosis demands that one has at least 3 of 6 symptoms through the previous year (ICD-10) or 4 of 7 at one point in life (DSM-IV). One does not need to have symptoms from all three groups, for instance is lack of control not a prerequsite.
Compared to regular medical diagnoses, it's remarkable that the important boundary between healthy and ill is set at an arbitrarily chosen number of symptoms (3 out of 6 or 4 out of 7)
Can "addiction" explain behaviour?
It follows from the diagnosis criteria that addiction describes a dangerous and/or harmful lifestyle. Often, however, addiction is not used merely as a description of behaviour, but as an explanation - with pretentions of diagnosticating a psychopathological process: "He does it because he is addicted"
The psychologist William Rohen(1) pointed out that "addiction" is a "ghost-in-the-machine"-explanation: We see behaviour that we cannot immediately explain, and say that there is something mystical, invisible inside man that is the cause.
"Continued use despite harmful effects" is not a clear symptom of illness, as we all can do things despite knowing that they are risky, or that we shouldn't really do them.
Recreational drugs give physical addiction, defined by increased tolerance and abstinence symptoms. This contributes to the postponement of rehabilitation. But almost all drug abusers are sober in periods. The problem is that they resume use later. Hospital patients who recieve morphine often get worse physical addiction than street users, but they accept the unpleasantness associated with withdrawal.
Lack of control was the main point in the alcoholism theory. But many people with a high consumption of drugs feel they are in control, and demonstrate it by abstention when the situation demands it. This is also shown in experimental research.
Lack of control can not explain activities we can choose to abstain completely from (drug use and gambling), merely activities we can't avoid (like eating).
Is addiction the main part of the problem?
In the area of drugs, and also gambling, it is currently common to speak as if "addiction" is the main problem.
There has been most research on the issue of alcohol. There, most of the problems are related to drunkenness among young and young adult men, not to daily drinking in those age groups which dominate alcoholist-treatment. Epidemilogical research shows consistently that when our grandparents connected alcohol problems to "drunkenness", they were more right than those who now connect it to "addiction" or "alcoholism".
The individualisation of collective problems
Our grandparents met the old social problems of alcohol and gambling through collective measures. In a poor society without professional rehabilitators, the intuitive understanding was that these were collective problems, in other words that high alcohol consumption and gambling in a society would cause problems (as science has shown in the last decades, both for alcohol and gambling). The problem-causing activities were strongly reduced through personal abstention and legal regulations. The measurable problems from alcohol reached a low point before second world war, and gambling problems were minimal until the legal deregulation of the nineties.
Even though treatment can help individuals, our current focus on addiction has probably not become popular for its results. Alcohol damages are for instance highest in those regions where consumption is highest, despite these regions having the highest number of alcoholist rehabilitators.
However, the focus on the addicted has popular consequences for society's way of fighting the problems: It implies promises that society can both have their cake and eat it, too - have plenty of alcohol and gambling without being punished by the harmful effects.
Through the media, professionals form the popular opinion. Today, most professionals in these fields earn their living by treatment of individuals. It may seem that the rehabilitators' problem is that they see many trees (individuals), but they rarely notice the forest (society's problems as a whole). The rehabilitators' professional interests are also served by a strong focus on those idividuals who seek treatment. But population studies have shown that only a very small part of problem users ever seek treatment for their problems.
Do we today have biological explanations for addictive behaviour?
Humans are born with different inherited characteristics, and behaviour ultimately consists of biochemical processes in cells. Will psychology and behavioural fields soon become subfields of genetics and biochemistry, or is that still light years away?
The biological behavioural scientists have always explained that they have made many promising finds that soon will lead to decisive breakthoughs - and therefore they of course need increased funding. In the previous years, biological researchers in the drug field have claimed that the breakthrough has partially arrived.
In 1990 reports went around the world that scientists (2) had found the "gene for alcoholism". But later studies showed that this gene occured with precisely the same frequency in regular people as in alcoholics.(3)
In Aftenposten, in the summer of 1997 we could read a statement from a norwegian drug expert: "Now we know that drugs have that in common that they increase the amount of dopamine in nucleus accumbens".(4)
By interpretations of animal studies it is currently claimed that a common biochemical "reward"-reaction occurs in drug use, laughter, sex, a good meal etc. The theory says that neurotransmittors and particularly the dopamine processes in nucleus accumbens can:
- explain why drugs are used
- soon explain why some use drugs regularly and in harmful ways
- soon give us medicines which can heal drug addiction.
But to believe that we here find the main explanation for drug use we have to disregard many known facts:
- animal experiments show that the dopamine amount in nucleus accumbens increases not only by positive stimuli, but also from negative (aversive) stimuli. It also happens with stimuli the animals try to avoid, such as pinching in the tail or electric shock.
- dopamine increase is documented for only a handful of the more than 200 drugs on the norwegian narcotics list.
- If dopamine increase was a common identifier of drugs, we could let laboratories decide whether a chemical is a narcotic. But the decision is left to the highly subjective experiences of drug users, coloured as they are by expectations, experience, sats often gets a higher status than psychology and social science. Many accept the theories because they lack their own knowledge to dispute them. Biological and genetical explanations are currently "in", where chemical determinism replaces the view of man as an actively deciding individual in a social context. But how large is the transition value from rodents in american research laboratories to humans affected by their relations, values, social situation and so on?
It is a beautiful theory that humanity's joys, excesses and drug use all can be explained from a single chemical reaction. One has to think of the words of the biologist Thomas Huxley: "A beautiful theory, killed by a nasty, ugly little fact".
Addiction is a correct, but not particularly deep, description
We are currently witnessing that many exaggregated activities are classified as "addiction". For these activities
- psychologists make very similar diagnosis schemas
- rehabilitators establish treatment facilities
- epidemiologists map the extent of the problems in populations
- medical professionals collect physical signs, hoping to find biological causes to the behaviour.
The rule is that those who show exaggregated behaviour, also more than usually like this activity, even if harmful effects create an ambivalence. Therefore the behaviour does not fit psychiatric definitions of compulsive behaviour, and therefore very few seek treatment.
When professionals say that a person is "addicted", that can be entirely correct. But it is probably not particularly deep, and does not really tell us anything more than that the behaviour is exaggregated. Despite diagnosis schemas it does not say more than common people's use of the term in norwegian everyday speech. The adoption of the term by professionals is a sign of an interesting cultural shift from earlier times, a so-called paradigm shift, not that new research has shown that exaggregated use is about illness.
We shall of course not throw the baby out with the bath water. Just in case, it needs to be pointed out: to point out that the description "addicted" is an expression of common-sense and is not particularly deep, does not mean that addicted people don't need help to modify their behaviour. Old habits are often very hard to change. Drug use has been a part of their adaption to their situation in life. Think only of drug abusers who often completely lack the skills thrive in society!
