Addiction
v Introduction
Our addiction theories and policies are woefully outdated. Research shows that there are no demon drugs. Nor are addicts innately defective. Nature has equipped U.S.A. all with the flexibility to become hooked—and we have a tendency to all interact in addictive behaviors to some extent.
Millions of Americans area unit apparently "hooked," not solely on diacetylmorphine, morphine, amphetamines, tranquilizers, and cocain, however additionally plant toxin, caffeine, sugar, steroids, work, theft, gambling, exercise, and even love and sex. The War on medicine alone is older than the century. In the early 1990s, the United States spent $45 billion waging it, with no end in sight, despite every kind of addiction treatment from psychosurgery, psychoanalysis, psychedelics, and self-help to treatment, cluster confrontation, family therapy, hypnosis, meditation, education and tough love.
There seems no end to our "dependencies," their bewildering intractability, the glib explanations for their causes and even more glib "solutions."
The news, however, is that brain, mind, and behavior specialists are re-thinking the whole notion of addiction. With facilitate from neurobiology, biological science, pharmacology, psychology, and genetics, they're challenging their own hard-core assumptions and popular "certainties" and finding surprisingly common characteristics among addictions.
They're exploitation new imaging techniques to ascertain however addiction appearance and feels and wherever cravings "live" within the brain and mind. They're last that things area unit aloof from hopeless and that they area unit quickly replacement conjecture with facts.
For example, scientists have learned that each animal, from the ancient hagfish to reptiles, rodents, and humans, share the same basic pleasure and "reward" circuits in the brain, circuits that all activate once in touch with addictive substances or throughout gratifying acts like consumption or consummation. One conclusion from this proof is that addictive behaviors area unit traditional, a natural a part of our "wiring." If they weren't, or if they were rare, nature would not have let the capability to be habitual evolve, survive, and stick around in every living creature.
What we now call "addictions," in this sense, Childers says, are cases of a good and useful phenomenon taken hostage, with terrible social and medical consequences. Moreover, that insight is leading to the identification of specific areas of the brain that link feelings and behavior to reward circuits. "In the case of addictive drugs, we know that areas of the brain involved in memory and learning and with the most ancient part of our brain, the emotional brain, are the most interesting. I'm very optimistic that we will be able to develop new strategies for preventing and treating addictions."
The new concept of addiction is in sharp contrast to the conventional, frustrating, and some would say cynical view that everything causes addiction.
Ask ten Americans what addiction is and what causes it and you would possibly get a minimum of ten answers. Some will insist addiction is a failure of morality or a spiritual weakness, a sin and a crime by people who won't take responsibility for their behavior. If addicts want to self-destruct, let them. It's their fault; they choose to abuse.
For the abstainer and politicians, it's a self-control problem; for sociologists, poverty; for educators, ignorance. Ask some psychiatrists or psychologists and you're told that personality traits, temperament, and "character" are at the root of addictive "personalities." Social-learning and cognitive-behavior theorists will tell you it's a case of conditional reaction and meant or fortuitous reinforcement of inappropriate behaviors. The biologically oriented will say it's all in the genes and heredity; anthropologists that it's culturally determined. And Dan Quayle can blame it on the breakdown of family values.
v Absolving the Diseased
The problem with all of these theories and models is that they lead to control measures doomed to failure by mixing up the process of addiction with its impact. Worse, from the scientific standpoint, they don't hold up to the tests of observation, time, and consistent utility. They do not make a case for abundant and that they don't account for tons. For example:
Not all drugs of abuse create dependence. LSD and different hallucinogens, caffeine, and tranquilizers are examples. Rats, for example, which can be easily addicted to heroin and cocaine just like humans, "just can't appreciate a psychedelic experience," notes Childers. "The same is true of marijuana and caffeine; it's hard to get animals to take them. People take these medicine for various reasons, not to feel pleasure."
At the same time, rats and other animals can become physically dependent on alcohol, but won't seek out alcohol even when they are in convulsions of withdrawal. Says Jack Henningfield, Ph.D., an addiction researcher at the National Institute of Drug Abuse in Baltimore, "we can get rats physically dependent on alcohol and even get them to go through DTs by withdrawing them. But we can't get them to crave alcohol naturally." Apparently, they have to learn, to be taught to want it. "Only when we give them the rat equivalent of smoke-filled rooms, soft jazz, and other rewards will they seek out alcohol."
Some substances with dearly addictive properties area unit nearly universally used and socially acceptable. Giving up coffee and colas containing caffeine can yield rapid heart beats, sweating, irritability, and headaches—markers of withdrawal.
People will expertise withdrawal syndromes with medication that do not addict them or build them physically or psychologically dependent. Postsurgical morphine is always withdrawn gradually in the hospital, but most people who get morphine still undergo so-called white flu—flu-like symptoms after they leave the hospital. They are actually undergoing withdrawal symptoms, but they have not become dependent on or addicted to the morphine. There is additionally no proof that terminal cancer patients in severe pain get "high" on serious doses of opiate, although they do become dependent.
Some medicine of abuse manufacture tolerance and a few do not. Heroin addicts want additional and additional of it to avoid withdrawal symptoms. Cocaine produces no tolerance, yet most would say cocaine is far more addictive because craving accelerates to sometimes lethal doses.
