Is addiction a disease? I find the behavioral aspect of addiction fascinating because it is a controversial subject. While the medical community does generally classify alcoholism/drug addiction as a disease, controversy stems from disagreements about the use of the word. "Disease" has several definitions. The most relevant definition to this paper is: "any harmful, depraved, or morbid condition, as of the mind or society." There are valid arguments supporting either side of this debate. Some say that addiction is purely in the mind--a learned behavior--while others will argue that addictive behavior is genetic. I believe it is probably a combination of both genetic predisposition and exposure to drug/alcohol use. For the purpose of simplification in this paper, drug addiction and alcoholism will be considered one and the same, as they often overlap in many individuals.
The disease theory of alcoholism was first proposed in the early 1800s by Dr. Benjamin Rush. Alcoholism does in fact follow the disease model in many ways. Addiction exhibits the properties of a disease in that it gets progressively worse, without the 'victim' having much control over progression, and often leads to hospitalization or death.
As to just why addiction is such a problem for some people is a question researchers are still puzzling over. I know many alcoholics and drug addicts myself, and often wonder what drives them to hurt themselves so--it truly does seem, at least on the surface, very similar to any other sort of disease. Often addicts will do, for lack of a better word, stupid things to satiate their addictions; i.e. get high before a test, or before work. I have a hard time justifying this as just pure stupidity because I know these people not to be total idiots in other aspects of their lives.
Most researchers agree that drug/alcohol addiction is partially attributed to genetics, as are many other degenerative diseases like multiple sclerosis, diabetes mellitus, or osteoarthritis. Addiction has been proven to run in families, which is an indicator that it has something to do with genetic predisposition. Not all addicts or alcoholics are born to addicted or alcoholic parents, either, which is evidence that it is at least partially a learned behavior.
It is difficult to absolutely prove that addiction is a disease, however, because it does not exhibit all the standard symptoms of a disease. Drug addiction or alcohol abuse are both self-inflicted, where other diseases are not. Given the opportunity to stop using a drug that the user knows is harmful, such as methamphetamine, users will continue use despite the risk. I doubt that many people with a true illness, such as aids, would voluntarily keep their affliction. Another difference between an addiction and a standard disease is that an afflicted individual does not exhibit any observable out-of the ordinary symptoms. That is, one cannot tell that an individual is an addict just by looking at them or speaking with them. It is also very difficult to prove that an individual is 'cured' of their addiction, simply because, again, there are no observable symptoms of the "curedness." A "cured" individual may go months or years without using, and suddenly relapse of their own choice--this does not happen with other diseases. When one gets over a illness such as a cold, that particular disease is forever cured--one might catch a cold again, however, the second cold is a separate, slightly different virus; a new disease altogether.
An aspect to consider on the issue is that there are those with a vested interest in maintaining the idea that alcoholism/drug addiction is a disease, because treatment is a very profitable industry. Each year millions of dollars are spent by patients in both in and outpatient rehab, there is quite a bit of money to be made in the field of rehabilitation. Because there is such an amount of money to be made in the area of addiction recovery, it is difficult to create truly unbiased studies, as so much profit lies in the outcome of said studies. A good example of this is the class of drugs known as SSRIs (specific seratonin reuptake inhibitors). SSRIs are very commonly prescribed for a plethora of reasons, from depression to anxiety. They gained popularity as a replacement for barbiturates, because SSRIs have little to no abuse potential when compared to barbiturates. The long-term effects of SSRIs are not very well documented, however that does not appear to dissuade doctors from (in my opinion at least) over prescribing them due to pressure from pharmaceutical companies.
Due to the fact that it is so difficult to classify the exact type of problem addiction is, and even more difficult to isolate the cause of the addiction, treatment becomes extremely difficult, often addicts struggle with the problem for their entire lives.
Although the I can see the case for it, I personally have trouble classifying addiction as a disease. This is because I feel that choice is involved, at least to some degree. If, as I believe, (Sane) people do not choose to become ill or to remain ill. , then it follows, therefore, that because drug addicts choose to use--despite the negative consequences—that this is a psychological disorder. However I do not feel that its fair to those afflicted with legitimate illnesses to compare them with people who essentially bring it upon themselves.
