Addiction And The Brain
Addiction is still somewhat of an unsolved mystery and no one is exactly sure how a certain substance acts on the brain. A popular definition of addiction is progressing from liking the substance to needing the substance and constantly seeking it out despite any negative consequences the user may experience. There is still much research to be done in the field of addiction especially alcoholism. The mechanism alcohol utilizes is disinhibition of GABA in the brain. GABA is an inhibitory transmitter and when it is being disinhibited it is being released more into the brain. This increase of GABA levels in the brain cause the user to feel calm and relaxed.

    Addiction: A Three-Part Disease

    In order to better understand addiction as a disease as opposed to a moral dilemma it first must be broken down. First you must look at the way in which the chemicals affect the brain. The first attempt at partaking in any mind altering substance can be looked at as a choice to the individual. However what happens after that first time? Are you then in control of how much or how often the substance is introduced to the body? As the substance is consumed it begins to alter the way in which the brain controls our feelings; happy, sad, anger, depression, etc. The brain tries to compensate for the influx of chemicals by reducing the amount of dopamine (a simple organic chemical in the brain system that is responsible for reward-driven learning). Thus when the substance is no longer in the system you can experience extreme “lows” that directly relate to depression. The brain then tells the body that it needs more of the DOC (drug of choice) to make up for that loss. It can be argued that once the levels of dopamine have diminished in the brain the choice of whether or not to use the DOC has been lost. Subconsciously the individual will experience the phenomenon of “craving”. As stated by the National Institute on Drug Abuse, “The initial decision to take drugs is mostly voluntary. However, when drug abuse takes over, a person 's ability to exert self control can become seriously impaired. Brain imaging studies from drug-addicted individuals show physical changes in areas of the brain that are critical to judgment, decision-making, learning and memory, and…
