To understand why drugs are addictive, it can be helpful to first have a complete understanding of what addiction is. Addiction is scientifically defined as “an unremitting, regressing brain disease which is distinguished by obsessive drug usage, despite dangerous consequences”. It is also sometime defined as an addictive bad habit Considering those definition it may be difficult to understand such behavior. In fact, that lack of understanding has resulted in poor and ineffective treatment of drug addicts. Scientists have already completed much work that has resulted in a better understanding of drug addiction and better treatment for drug addict. More work is continuing to be done and better treatment will hopefully follow.
It is important to point out that addiction is conceived as a disease. The primary reason for this classification is that drug use actually changes the physical structure and function of the brain. Those changes could be enduring and facilitates many of the destructive behaviors which get easily associated with drug addiction. On the other hand the disease concept strips the substance abuser of most of his responsibility.
A look at some of the reasons that people begin using drugs may also provide insight as to why a particular person becomes addicted to drugs. Among the most common reasons that people begin using drugs is to feel good. This is a highly-motivating reason to do anything. Unfortunately, with continued drug use the euphoria (good feeling) may last for less time; it may require more of the drug to achieve that level of euphoria, and the individual may only feel good when taking the drug. Another common reason some people take drugs is to do better. There are often negative effects that accompany the desired effects of any drug. Use of the drug may actually result in diminished performance when the individual is not using the drug.
There are some key factors that increase the potential for addiction in individuals. Among the most influential are environment and the method that the drug is administered. The first element, environment, is a key element in a number of ways. Parents, peers and the area that an individual lives in can determine factors like what age the individual will first be exposed to the drug. It may also influence the individual’s perception of the drug. If drug use is accepted by everyone around the individual there may be greater likelihood of the individual trying the drug or beginning regular use. The method of the drug’s administration is a key element because it determines, to a large degree, the experience of the drug use. Usage that involves smoking or injection produces a more intense euphoria with a quicker onset. These also result in higher rates of addiction.
Each individual is different, but the changes that result from drug use are the factors that shape the brain and the addiction.
