THE PSYCHO-BIOLOGY OF ADDICTION

Who gets addicted to alcohol -- and why?


by Alan Cauldwell, Ph.D.

Not everybody who drinks is an alcoholic or becomes one. That seems obvious, but why does one person drink all his/her life and never become an alcoholic and another becomes an alcoholic inside of the first year of picking up a drink? No one knows. No doubt there are many factors involved.

One theory suggests that if a person drinks enough (quantity) over a long enough period of time, s/he will become an alcoholic. Alcohol is classified in pharmacology texts as a sedative hypnotic; the same as Quaaludes and other "downers". Simply put, alcohol is addictive. So this bit of information raises a couple of questions. The first question is what is "enough" alcohol and just how long does it take to become addicted? The tricky answer is, it depends on the individual. The second question is how does one actually become addicted? The answer to this? Well, there's a theory....

To start with, many professionals who work in the addictions field see drinkers as falling into one of four classifications: 1) social drinkers, 2) life style drinkers, 3) problem drinkers and 4) alcoholic drinkers.

Social drinkers, for example, drink a glass of wine when served with a family dinner. While they may enjoy the effect of the alcohol, they don't need more, nor do they continue to drink after dinner, or the next day. In short, they can take it or leave it.

Life style drinkers are personified by the businessman or woman who comes home and has a drink at 6:00 o'clock. They won't (or rarely) have a drink during the day, but they generally drink every day, and it is important to them. They limit themselves, they monitor themselves, but drinking is part of their lives. Life style drinkers often become problem drinkers.

Problem drinkers often drink to self-medicate - drinking to anesthetize a painful feeling or the perception of an intolerable situation. So when a problem drinker drinks, it interferes with some aspect of his/her life. In the majority of cases, alcoholic drinkers were problem drinkers.

Alcoholic drinkers are dependent on alcohol. Alcohol has taken over their lives, which "have become unmanageable." Yet there is a paradox here, which is one of the hallmarks of the disease of alcoholism. Alcohol has rendered the alcoholic dysfunctional, but without some alcohol the alcoholic believes s/he cannot function. And there is a strange truth to this, for when alcohol is taken away, the alcoholic becomes sick, but if the alcoholic were to then take a drink, s/he would feel "ok."

So to our second question, what happens to create this peculiar dependence on alcohol? First, it is important to know that the body has evolved what is called the opiod system. This system is made up of neuropathways within the central nervous system. These neuropathways produce natural opiates (such as endorphins and encephalins). Runners and athletes know these natural opiates, which when activated, produce the "runner's high." The opiod system acts as the body's natural defense against both physical and psychological pain. The system serves as an insulation barrier, protecting both body and mind from undue stress.

Not surprisingly, the key to understanding what happens in the physical addiction of alcohol lies in the liver, and subsequently in the central nervous system. When alcohol hits the liver a number of complex chemical reactions take place, the upshot is that a chemical known as TIQ (tetrahydrosioquinolines) is produced. TIQs are very much like hardcore opiates (e.g. morphine and heroin), and are far more potent than the subtle natural opiates found in the body.

When the liver manufactures TIQs, they enter the body's opiod system, and the drinker feels "high." By the time a person becomes an alcoholic, the opiod system has become saturated with TIQs so the body has stopped manufacturing its own natural opiates. The individual becomes dependent on--or addicted to--the TIQs since s/he no longer has his/her own natural opiates. The system now begins to crave the stimulation provided by TIQs.

When alcohol is then withdrawn, the system goes into a shock reaction. The body, now without its normal insulation barrier from internal and external stressors, feels "raw", and cannot immediately start manufacturing its own natural opiates. The individual begins to feel sick, and feels desperate for alcohol in order to "get right." This is what everyone knows as withdrawal. The more pronounced the alcoholism, the worse the withdrawal.

There are many other factors that go into the "making" of an alcoholic (mostly psychological) and the severity of withdrawal. But the manufacture and use of TIQs may be the most significant factor in creating the physical aspect of the disease.

So what does this evidence suggest to people who drink and to people who are addicted to alcohol? First, the social drinker is probably okay; that is if s/he is able to maintain his/her current style of drinking, chances are the body will not "change" and require alcohol to maintain its physical and psychic protection.

Second, it indicates, however, that we may all be prone to alcohol addiction. If a person drinks enough (too much) alcohol over a long enough period of time s/he may become addicted. Who knows how much alcohol abuse it will take for a metabolic change to occur in a person causing the body to "require" alcohol?

Third, this underscores what Alcoholics Anonymous has said for many years, that alcoholism is a disease not a weakness of character. (It should be noted that there are many personality issues which may cause the individual to choose alcohol--to self-medicate--as a way of dealing with problems and alcoholism itself creates personality changes.)

Finally, the problem drinker and alcoholic drinker are either destroying or have destroyed their insulation barrier and they must stop drinking. The alcoholic drinker is like a person who slowly takes off a heavy down coat in sub-zero weather. Soon the cold is unbearable, if not deadly. The longer it goes on the worse it gets.

There are alternative methods for developing and maintaining a psychic-warm-coat, helping us interact with our environment more safely, comfortably, and effectively. Various physical, psychological, and spiritual approaches offer ways to develop and maintain a healthful sense of insulation from the "slings and arrows" that life throws at us. I'm reminded of a poster from the 1960s. On it was a picture of a serene yogi, standing in a yoga posture, superimposed on top of a surfboard racing down a huge wave. The caption read, "You can't control the waves, but you can learn to surf them." If we use alcohol to try to control the treacherous "waves" that we encounter in our lives, we just might drown. Better to get a good surfboard and enjoy the ride.
