Effects Of Drugs On The Brain

4271 words - 17 pages

Drugs have become a very serious problem in the United States. They havebecome a component of one's every day lives. This Nation's reliance on drugs forpleasure, depression, and medical relief dominates the political and economic scene.Much debate over the drug issue occurs daily. Drugs such as caffeine, nicotine and alcohol are legal drugs and drugs like marijuana, cocaine, and heroine are illegal but all of these drugs affect our brains and transform out lives.Drugs bind to receptor sites on the outer membranes of cells. Like a key that must fit a lock, the drug molecule has to fit a receptor; otherwise it has no effect. If it fits, then the drug can interfere with transmissions between neurons in one of two ways: Some drugs cause neurons to fire again and again. Other dugs stop neurons from firing. These drugs block receptors in the brain and prevent neurons from sending their message.There are hundreds of different drugs, each with its particular effect on the body's nervous system. For instance, narcotics are a series of drugs that affect the mind, causing mental changes. The United States Government will not allow new drugs to be prescribed by a doctor or sold by a pharmacist until the drug has been thoroughly tested and proven to be medically safe. These tests take as long as years to be approved for public use. Unstable drugs are street drugs such as crack, cocaine, heroin, LSD, and MDMA that are made up of several chemical substances that are produced illegally under poor circumstances. Some drugs that are stable are still highly addictive and can cause a number of problems in an individual's life. Certain drugs are responsible for killing thousands of people each year. Those who escape death are sometimes confined to a mental institution.Alcohol is the most used and abused drug in the world. This is how alcohol affects the brain. The more a person drinks, the more parts of the brain malfunction. Self-control goes first, as alcohol affects the frontal lobes where plans, judgments, and decisions are made. Next alcohol works its way down into the areas where language and memory reside. With still more drinking, alcohol begins to interfere with the basic process of life controlled deep inside the brain-emotion, movement, heartbeat, and breathing.No one knows exactly how alcohol does these things. Some scientist think it makes the membrane of the neuron so leaky that sodium and other chemicals can move in and out too easily. Some evidence suggests that alcohol binds to the receptor site for the neurotransmitter GABA, which may explain how alcohol calms anxiety. It may also bind to the receptor for another neurotransmitter, glutamate, causing loss of muscular control, delayed reaction time, and fuzzy thinking. It also appears that some neural pathways just shut down entirely when flooded by alcohol.Alcoholism is a chronic usually progressive disease that includes both a psychological and a physical addiction to alcohol. Alcoholics know what...
