A drug is any chemical substance that can alter the structure and function of a living organism. People use drugs for many reasons. Some individuals need drugs for health reason-to maintain a normal life or to alleviate specific symptoms or complications of diseases or other conditions. Other people indulge in drugs to alter their moods.
Reasons people use drugs
Researchers have identified several reasons people use drugs:
Medical purposes: Medicines are used for a wide range of purpose - from reducing symptoms of the cold and flu or treating headaches to lowering blood pressure or cholesterol to extend life and maintain quality of life. Because of chemical imbalances, individuals who suffer from condition, such as bipolar disorder or depression, would be unable to live normal lives without the availability of certain drugs. Methylphenidate (Ritalin), commonly used as a stimulant illegally, is also used to treat adults and children who have attention-deficit disorder. When used in this capacity, Ritalin frequently helps them focus on and complete tasks-something they frequently have difficulty doing without medical intervention. Drugs as medicines, although dangerous even under a physician's care when misused or prescribed incorrectly, are invaluable to many for maintenance of an active, successful lifestyle.
Recreational/social facilitation : People frequently use drugs that they believe will lessen the tension associated with social encounters. Marijuana and alcohol are particularly popular in social situations. Potential dangers of using drugs for this purpose include mental dependency on the drug and an inability to cope with social events without using the drug.
Sensation seeking: Some people enjoy taking risks. For them, drug fulfill the need for excitement and adventure. Others turn to drugs out of boredom or a sense of inadequancy in their lives. They are seeking sensations of pleasure that are artificially induced. Unfortunately, when drug tolerance occurs or they do not find the type of "high" they were looking for, users frequently turn to increasingly dangerous drugs or to increased doses to provide equivalent or more exciting thrills.
Religious or spiritual factors: Throughout history people have used drugs to enhance their spirituality or become more godlike. Too often the drug becomes the object or worship rather than the god or spiritual essence being sought. Though many people have tried, the spiritual realm has not been achieved through use of mind-altering drugs.
Altered states: Drugs are sometimes used to increase the intensity of a mood or create a state of euphoria. Some people attempt to enhance physical performance or stimulate artistic creativity. Evidence indicates that perceptions of improved abilities are false.
Rebellion and alienation: The use of drugs can be a deliberate act of rebellion against social values, especially the values of parents or society. Individuals who experience extreme pressures and have difficulty coping frequently turn to drugs as an escape. This includes college-age students facing academic pressure and increased personal freedom.
Peer pressure and gout entry: People who have a great desire to feel accepted often use drugs to demonstrate their sameness with other members of the group. Feeling accepted, modeling behavior after someone who is admired, and attempting to create an identity or specific image are reasons offered for drug use. Self-esteem seems to be a vital component. Individuals with high self-esteem see themselves as competent, successful, self-sufficient, accepting, outgoing, and wall rounded. People with low self-esteem tend to feel isolated and unloved and have a reduced capacity for joy or self-fulfillment. In the attempt to magically overcome these sensations and perceptions, many people turn to drugs.
Curiosity: Often, individuals first experiment with drugs out of curiosity-the desire to see what using the drug feels like or what the attraction is for chronic users. Although curiosity is normal and healthy in many circumstances, the primary problem associated with experimentation with drugs out of curiosity is the inability to know how a drug will affect any one human being. Whereas friends may consider the effects of a drug pleasurable, someone else may have a different, occasionally fatal, reaction. Most people try alcohol during their life. For most people this creates no problem; they can choose to use t or not use it. For some people one act of curiosity can use it. For some people one act of curiosity can result in the disease of alcoholism.
What is a Low Glycemic Diet A recent Harvard study found that a low-glycemic diet was the best of three popular diets at both maintaining metabolism during weight loss and maintaining cardiovascular health. But what is it and what are low glycemic foods anyway?
The diet, which is also known as the glycemic index diet or GI diet, emphasizes unprocessed foods, complex carbs and food combining. It was originally developed as a diet to help diabetes patients regulate their blood sugar and, according to WebMD, is still most effective in this capacity. Many popular diets, including Nutrisystem, the Zone diet, Sugar Busters and South Beach diet incorporate low-glycemic principles.

Progeria Information and Facts Are you looking for progeria information and facts? here is some information about progeria.
Progeria is an extremely rare genetic condition wherein symptoms resembling aspects of aging are manifested at an early age. The word Progeria comes from the Greek words "pro" means "before" and "géras" means "old age". The disorder has very low incidences and occurs in an estimated 1 per 8 million live births. Those born with progeria typically live to their mid teens and early twenties. It is a genetic condition that occurs as a new mutation (de novo), and is not inherited. Although the term progeria applies strictly speaking to all diseases characterized by premature aging symptoms, and is often used as such, it is often applied specifically in reference to Hutchinson-Gilford Progeria Syndrome.
Food Borne Illness Prevention Most of us have experienced the characteristic symptoms of diarrhea, nausea, cramping, and vomiting that prompt us to say, “It must be something I ate.” The number of cases of food poisoning in the United States has been growing (there are three millions of cases per year), which has prompted the Food and Drug Administration to make prevention of food contamination a high priority. Deaths in Pacific Northwest in 1994 attributed to consumption of Jack-in-the-Box hamburgers contaminated with Escherichia coli, a bacterial agent, increased people’s fears about the overall safety of meat, poultry and seafood.

What are Water Functions Next to air, water is the substances most necessary for survival. Most everything in the body occurs in a water medium. Although people can live without vitamins and minerals for extended periods, death result within a few day without water.
Water makes up about 60% of the body's weight. Every cell in the body is bathed in water of the exact composition that is best for it. Even tissues that are not thought of as "watery" contain large amounts of water. Fo example, water makes up about 75% of brain and muscle tissues; bone tissue and fat tissue are about 20% water.

Ear Infection Treatment Adult and Antibiotics Are you looking for Ear Infection Treatment for Adult and what are Antibiotics for ear infection?
Ear infections occur when a cold, throat infection, or allergy attack causes fluid to become trapped in the middle ear. Mostly affecting children, symptoms include earaches and thick, yellow fluid coming from the ears. A small tube connects your ear to your throat. These two tubes are called eustachian tubes (say "yoo-STAY-shee-un"). A cold can cause this tube to swell. When the tube swells enough to become blocked, it can trap fluid inside your ear. This makes it a perfect place for germs to grow and cause an infection.
Detached retina causes and Treatment Normally, the retina is firmly attached to the choroid, and underlying layer of tissue that is rich in blood vessels. If blood or other fluid collects between the retina and the choroid, the retina may become partially or totally detached. Fluid from the vitreous cavity (the fluid-filled space behind the lens) may penetrate beneath the retina because of a small hole in the retina. Fluid leaking out of certain blood vessels in the eye may also penetrate beneath the retina to cause detachment.
Cymothoa Exigua in Human and Life Cycle Cymothoa exigua is a tiny crustacean that sneaks up on a fish (specifically, a red snapper) and works its way in through the gills. Typical parasite behavior so far.
Then it attaches itself to the base of the fish's tongue, the tongue evidently being the tastiest part of the fish (get it!?). The parasite uses its claws to dig into the tongue and drink the fish's blood--and that's just the beginning
Glucosamine Side Effects in Humans and Dosage Glucosamine (C6H13NO5) is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of the polysaccharides chitosan and chitin, which compose the exoskeletons of crustaceans and other arthropods, cell walls in fungi and many higher organisms. Glucosamine is one of the most abundant monosaccharides. It is produced commercially by the hydrolysis of crustacean exoskeletons or, less commonly by fermentation of a grain such as corn or wheat. In the US it is one of the most common non-vitamin, non-mineral, dietary supplements used by adults.
