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.

Downs syndrome Symptoms and Prevention Down’s syndrome is a congenital (present at birth) disorder characterized by varying degrees of mental retardation and a variety of physical abnormalities.
Down’s syndrome Causes
Normally, each cell in the human body has 46 chromosomes; the cells in someone with Down’s syndrome, however, have 47. In ways that are as yet unknown, the presence of the extra chromosome causes all of the unusual characteristics of Down’s syndrome. In 95 percent of cases, the condition is called trisomy 21 (because the extra chromosomes is attached to the twenty-first pair of chromosomes), and the mistake in genetic coding is one that apparently could happen to anyone. In five percent of cases, the syndrome is caused by a defect that is believed to run in families.
Symptoms of Gallbladder Dysfunction Are you looking for symptoms of gallbladder dysfunction? What is important to say when it comes to gallbladder symptoms is that people can be quite unaware that their digestion problems actually come from their gallbladder.

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. As a lee the bodies of women. Men have more muscle tissue, and muscle tissue holds more water that fat tissue, which is more prominent in the bodies of women.
The Foetal Circulation To understand the foetal circulation, it must be appreciated that the foetus develops its own blood and that at no time does the foetal and maternal blood mix unless some pathological process is present. The foetus produces its own red and white blood corpuscles. During intrauterine life the foetal gastrointestinal and respiratory system are not functioning, so the maternal blood furnishes the necessary nutrients and oxygen through the placenta, which in this case acts as the organ of respiration.
E Coli Symptoms There are many conditions with symptoms similar to those of E. coli infection. Diagnosis of E. coli infection can be complicated by the fact that most bacterial infections that cause diarrhea are accompanied by a high fever. If you have no fever or only a mild fever, your doctor may suspect that something other than bacteria is causing your symptoms.

Arteries, Veins, Capillaries and The Heart The blood away which carry the bright red oxygenated blood away from the heart are called arteries. The large arteries, which receive the blood directly from form the heart, branch repeatedly until every part of the body is served by one or more of them.
The blood returns from all parts of the body to the heart through veins. There are many more veins than arteries throughout the body. The veins gradually unite to form larger veins as they approach the heart.
