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.
Stages and Effects of Pyrexia and Hyperpyrexia A pyrexia is a body temperature between 37.60 and 400C and hyperpyrexia is a temperature > 400C. They are conditions in which the thermoregulatory mechanisms are intact but the body temperature is high. Infection s the most common cause of pyrexia and sepsis of hyperpyrexia but there are other causes. A number of drugs have been associated with pyrexia, e.g. diuretics, antiseizure therapy, analgesics, antiarrhythmics and antibiotics. Other causes of pyrexia include neoplasm, surgery, acute myocardial infarctions, heart failure, haemolysis (seen in reactions to blood transfusions) and hyperthyroidism.

Psoriasis Symptoms in Children Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. You usually get them on your elbows, knees, scalp, back, face, palms and feet, but they can show up on other parts of your body. A problem with your immune system causes psoriasis. In a process called cell turnover, skin cells that grow deep in your skin rise to the surface. Normally, this takes a month. In psoriasis, it happens in just days because your cells rise too fast. Here is some stuff about Psoriasis Symptoms in Children.
Drugs for Depression Are you looking for drugs for depression? here is some good stuff about drug for depression.
Depression is a state of low mood and aversion to activity that can affect a person's thoughts, behavior, feelings and physical well-being. It may include feelings of sadness, anxiety, emptiness, hopelessness, worthlessness, guilt, irritability, or restlessness.
Immunization for children and schedule You can see the diseases, vaccine-preventable diseases in this column and the number of cases reported prior to routine immunization and then the number of cases reported last year in this country. Youíll see a real dramatic decline in these vaccine-preventable diseases. Between 95 and 100% decline and this is due to routine immunization against these diseases. So this is a very dramatic success story, and because of this - this is from the MMWR published by the CDC - the top public health achievement of this century in this country is routine vaccination. So you can be assured that this is something that will be on the Boards because itís been such a tremendous success, a tremendous achievement and it is very important.
Breast Cancer Treatment and Therapy Guidelines What about the follow-up after our primary and adjuvant treatment for breast cancer? We know from many good signs that most of the recurrences are found by patients, second most by physicians and almost never by routine tests. Therefore, the official recommendations for follow-up of asymptomatic individuals after primary therapy is that they have history and physicals about every four to six months and that they have annual mammographies. There are no films, scans, tumor markers that are indicated in the follow-up of asymptomatic individuals. So, we usually suggest a history and physical every three to six months and an annual mammography. This is something that is continually under review. It might change, but today, all of the studies that have been done have never been able to show survival benefit for intensive screening with radiographic and blood testing as opposed to just clinical follow-up of these patients.
Metastatic breast cancer. If breast cancer is found to have spread at the time of diagnosis or recurs later after local therapy, we have a situation which cannot be realistically considered to be a curable disease at this point. I think that is important. It is equally important however to recognize that the survival ratio with metastatic breast cancer is very, very variable. If you have metastatic lung cancer or inoperable pancreas cancer, most of these patients are dead in year. Certainly within 18 months. There is almost no survival at two years with a disease like that. Breast cancer is all over the board. The median survival from onset of metastases is probably on the order of two to three years but all of us have patients who have lived 10 years or more in very good physical condition after the development of metastatic disease. So, again looking at the clinical parameters of what the disease-free interval is, what sites are involved, whether the hormone receptors are positive, can help you project somewhat what is going to happen but is a situation with an extremely variable prognosis.
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

Syphilis types symptoms and treatment Syphilis, the other well-known sexually transmitted disease, is also caused by a bacterial organism, the spirochete known as Treponema pallidum. Because it s extremely delicate and dies readily upon exposure to air, dryness, or cold, the organism is generally transferred only through direct sexual contact. Typically, this means contact between sexual organs during intercourse, but in rare instances, the organism enters the body through a break in the skin, through deep kissing in which body fluids are exchanged, or through some other transmission of body fluids.
Hiatus Hernia Treatment The term hiatus hernia describes diaphragmatic hernia or weakness in the diaphragm, the horizontal muscular wall separating the organs of the chest from the organs of the abdomen. A hernia is an abnormal protrusion of an organ or tissue through an opening. A hiatus, or opening, permits the esophagus to carry food from the mouth to the stomach. Blood vessels and nerves also pass through the diaphragm. The diaphragm is an important group of muscles for contracting and expanding the lungs, forcing air in and out of the lung tissues.
Nephritis Symptoms and Treatment Nephritis is a disorder characterized by inflammation of the glomeruli of the kidneys. The glomeruli are tiny coiled blood vessels through which the liquid portion of the blood is filtered as it enters the outer structure of the kidneys. There are about one million of these tiny blood vessels in each kidney. The fluid from the blood passes from them into many little ducts called tubules. Water and various substances are secreted into and absorbed from the liquid in the tubules. The final product of this passage of filtered fluid from the glomeruli through the tubules to the uterus and then to the bladder is urine. It contains the excess fluid and waste products produced by the body during normal functioning.
