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.
Kidney Stones Causes, Symptoms and Treatment Kidney stones are deposits of mineral or organic substances that form in the kidneys. When abnormally high levels of certain minerals, such as calcium, are in the urine, they may condense into hard masses, forming stones in the kidney or urinary tract. The stones may be as small as a tiny pebble or as large as a walnut.
Cocaine Effects on The Brain and Body At one time cocaine was considered the drug of upper-class America. Unfortunately, the use of cocaine and its derivative, crack, is now epidemic. It is estimated that 25 to 30 million people have experimented with cocaine in the United States. Approximately 5 million people use the drug regularly. Among young adults, 6,7% have tried crack and 40% tried cocaine. In a recent survey of high school senior, 1 in 18 admitted to trying crack and 14% used cocaine in other forms.
A powerful stimulant, cocaine is derived from the leaves of the South American coca shrub and ground into a crystalline powder. The most common methods of sung the drug are either snorting it, liquefying it and then injecting it, or freebasing (smoking). When snorted, the white powder is sniffed up through the nose. The most potent and expensive method of cocaine use is freebasing. The drug is usually smoked in a water pipe because this provides faster absorption into the bloodstream.
Symptoms of UTI (Urinary Tract Infections) in Women Pregnancy causes numerous changes in the womanís body. Hormonal and mechanical changes increase the risk of urinary stasis and vesicoureteral reflux. These changes, along with an already short urethra (approximately 3-4 cm in females) and difficulty with hygiene due to a distended pregnant belly, increase the frequency of urinary tract infections (UTIs) in pregnant women. Indeed, UTIs are among the most common bacterial infections during pregnancy.
FOODS CAUSE OF ALLERGY People may be sensitive to single or to multiple foods. Here again are some foods which are botanically related, so that if a patient is sensitive to one food in this group, he sensitive to the others. Examples of this may be cited in the case of cabbage, Brussels sprouts, and cauliflower. Many of the sea foods and fresh water fish are thus similarly related; so that if a patient is sensitive to one type of fresh water fish, he is likely sensitive to the others. The most frequent allergy-producing foods are common foods, namely, milk, eggs and wheat, fish and nuts. It is unfortunate that this is the case because these are also essential foods, and this avoidance becomes a serious problem in undernourished people and in children of infants. When a patient is definitely sensitive to one or two foods only, it is not difficult for him to realize it himself. The difficulty arises, however, when he is allege to many foods. Under these circumstances he is likely to become confused and then he needs a physician's help. Allergy to a food may be of various degrees of severity. Symptoms of asthma or hives may not arise if only one food is eaten if the sensitivity is mild. However, if a number of such foods are ingested at one time, the symptoms may be pronounced. Another factor which is important in connection with the production of symptoms is the readiness with which a food is absorbed from the gastrointestinal tract. The quicker the absorption, the more rapid will the symptoms develop after eating.
What is systolic blood pressure definition What is systolic blood pressure definition? Systolic blood pressure is the amount of pressure that blood exerts on vessels while the heart is beating. In a blood pressure reading (such as 120/80), it is the number on the top. If the top and bottom blood pressures are both too high, a person is said to have high blood pressure. If only the top number is higher than 140, the person has a condition called isolated systolic hypertension.

Pleurisy symptoms back pain Pleurisy (also known as pleuritis) is an inflammation of the pleura, the lining of the pleural cavity surrounding the lungs. Among other things, infections are the most common cause of pleurisy.
The inflamed pleural layers rub against each other every time the lungs expand to breathe in air. This can cause severe sharp pain with inhalation (also called pleuritic chest pain). Here is some stuff about pleurisy symptoms back pain.
Gangrene Causes, Symptoms and Treatment Gangrene is a term that refers to the death of body tissue due to diminishment or loss of blood supply, leading to nutrient and oxygen deprivation. There are three major types of gangrene: moist, dry, and gas gangrene. Although gangrene usually affects extremities, it can sometimes affect the internal organs.
Foods to help anemia treatment Abnormally low numbers of red blood cells and reduction in the amount of hemoglobin in those cells results in anemia. Because red blood cells are needed as carriers of oxygen to the tissues, oxygen supply to the body is subsequently interrupted. The exact cause of anemia must be diagnosed by physician before any treatment can begin.
Anemia can be caused bay an iron deficiency due to blood loss from excessive menstrual flow, gastrointestinal bleeding and ulcers, during pregnancy, breast-feeding, from frequent blood donations, colon cancer, or lack of iron in the diet. It can result from autoimmunity, a condition in which the immune system mistakenly attacks itself, in this case the red blood cells; or from a malfunction of the bone marrow system when it is adversely affected by infection, cancer or toxic chemical exposure or radiation. Anemia can also occur because of a deficiency of vitamin B6, B12, folic acid, or copper; and from certain anti-inflammatory drugs or antibiotics or an excessive consumption of alcohol. Genetics may also be a factor.
Spinal Stenosis Definition and Treatment What is defintion of Spinal Stenosis. Spinal stenosis is a narrowing of one or more areas in your spine ó most often in your neck or lower back. This narrowing can put pressure on the spinal cord or spinal nerves at the level of compression. Stenoses of the vascular type are often associated with unusual blood sounds resulting from turbulent flow over the narrowed blood vessel. This sound can be made audible by a stethoscope, but diagnosis is generally made or confirmed with some form of medical imaging.
aortic stenosis (AS) a narrowing of the aortic orifice of the heart or of the aorta near the valve.
hypertrophic pyloric stenosis narrowing of the pyloric canal due to muscular hypertrophy and mucosal edema, usually in infants.
How HIV Is Transmitted HIV typically enters one personís body when another personís infected body fluids (semen, vaginal secretions, blood, etc.) gain entry through a breach in body defenses. Mucous membranes of the genital organs and the anus provide the easiest route of entry. If there is a break in mucous membranes (as can occur during sexual intercourse, particularly anal intercourse), the virus enters and begins to multiply.
Mononucleosis symptoms children Are you looking for mononucleosis symptoms children? Infectious mononucleosis (IM; also known as EBV infectious mononucleosis or glandular fever or Pfeiffer's disease or Filatov's disease and sometimes colloquially as the kissing disease from its oral transmission or simply as mono in North America and as glandular fever in other English-speaking countries) is an infectious, widespread viral disease caused by the Epstein-Barr virus (EBV), one type of herpes virus, to which more than 90% of adults have been exposed. Occasionally, the symptoms can recur at a later period. Most people are exposed to the virus as children, when the disease produces no noticeable symptoms or only flu-like symptoms. In developing countries, people are exposed to the virus in early childhood more often than in developed countries. As a result, the disease in its observable form is more common in developed countries. It is most common among adolescents and young adults.
