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.
Ketogenic Diet Plan Menu Are you looking for Ketogenic Diet Plan Menu? The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate diet that in medicine is used primarily to treat difficult-to-control (refractory) epilepsy in children. It is unrelated to the diets used for bodybuilding and weight-loss, which often involve much lower levels of ketones. The diet mimics aspects of starvation by forcing the body to burn fats rather than carbohydrates. Normally, the carbohydrates contained in food are converted into glucose, which is then transported around the body and is particularly important in fuelling brain function. However, if there is very little carbohydrate in the diet, the liver converts fat into fatty acids and ketone bodies. The ketone bodies pass into the brain and replace glucose as an energy source. An elevated level of ketone bodies in the blood, a state known as ketosis, leads to a reduction in the frequency of epileptic seizures.
Signs and Symptoms of Hypothyroidism Are you looking for signs and symptoms of hypothyroidism?Hypothyroidism affects two out of every thousand women. It affects about 6-10% of women over the age of 65 and about 2-3% of men.
The most common cause of hypothyroidism is Hashimoto's thyroiditis, a chronic autoimmune destruction of the thyroid. Other causes of hypothyroidism include radioactive iodine, thyroidectomy, thioamide drugs, and iodine ingestion. Transient hypothyroidism can occur in patients with acute thyroiditis.
Treatments for Endometriosis Adenomyosis is endometriosis in the endometrium, specifically in the musculature, and if it is found below the basement membrane. Endometriosis has been found in an estimated ten percent of the general population. This was found a long time ago when we did tubal ligations on patients and saw endometriosis in normal fertile patients. However, endometriosis has been found in about twenty-five to thirty percent of infertile patients undergoing laparoscopy. So what are Treatments for Endometriosis?
No Carb Diet Menu Plan Are you looking for No Carb Diet Menu? Low-carbohydrate diets or low-carb diets are dietary programs that restrict carbohydrate consumption usually for weight control or for the treatment of obesity. Foods high in digestible carbohydrates (e.g. bread, pasta) are limited or replaced with foods containing a higher percentage of proteins and fats (e.g. meat, poultry, fish, shellfish, eggs, cheese, nuts, seeds and peanuts) and other foods low in carbohydrates (e.g. most salad vegetables), although other vegetables and fruits (especially berries) are often allowed. The amount of carbohydrate allowed varies with different low-carbohydrate diets.
Types of Schizophrenia and Symptoms Schizophrenia is a mental disorder characterized by a disintegration of thought processes and of emotional responsiveness. It most commonly manifests as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction. The onset of symptoms typically occurs in young adulthood, with a global lifetime prevalence of about 0.3–0.7%. Diagnosis is based on observed behavior and the patient's reported experiences.
Vitiligo Treatment 2011 in USA Are you looking for vitiligo treatment 2011 in USA? Vitiligo (pronounced vit-ill-EYE-go) is a pigmentation disorder in which melanocytes (the cells that make pigment) in the skin are destroyed. As a result, white patches appear on the skin in different parts of the body. Similar patches also appear on both the mucous membranes (tissues that line the inside of the mouth and nose) and the retina (inner layer of the eyeball). The hair that grows on areas affected by vitiligo.
Coronary Artery Disease Treatment Guidelines It can be difficult to determine whether chest pain is caused by angina. Whenever a person develops symptoms that could be angina, a complete medical evaluation is needed to determine whether coronary artery disease is present and, if so, how severe it is (see also chapter 7). The individual's medical history and descriptions of the pain, actions that cause the pain, and actions that make it better may raise a doctor's suspicion of coronary artery disease, but these factors are not sufficient for actual diagnosis. Likewise, physical examination and blood tests may show that the patient is at risk, but cannot actually diagnose the condition.
An electrocardiogram may or may not show changes of cardiac ischemia. An exercise electrocardiogram, a ''stress test'' done while a person is performing a specific amount of exercise, is more likely to demonstrate whether coronary disease is present. A particular change in the electrocardiogram during exercise can demonstrate that coronary artery disease is present. Even an exercise electrocardiogram is not 100 percent reliable in diagnosing coronary artery disease.
Dementia stages symptoms Are you looking for dementia stages symptoms? Dementia is a serious loss of cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging. It may be static, the result of a unique global brain injury, or progressive, resulting in long-term decline due to damage or disease in the body. Although dementia is far more common in the geriatric population, it can occur before the age of 65, in which case it is termed "early onset dementia".
Symptoms of dementia can be classified as either reversible or irreversible, depending upon the etiology of the disease. Less than 10% of cases of dementia are due to causes that may presently be reversed with treatment. Causes include many different specific disease processes, in the same way that symptoms of organ dysfunction such as shortness of breath, jaundice, or pain are attributable to many etiologies.
High Protein Foods List Are you looking for high protein foods list? here is some list for high protein foods.
Protein is an essential nutrient that is important to your health. Protein consists of chains of amino acids that are used by our bodies to grow muscles, hair, nails, skin and internal organs.
Diets rich in high protein foods are often recommended for athletes and body builders. In addition, many weight loss diets such as the Atkins diet prescribe a high protein, low carb diet.
Although protein is an essential nutrient, some research suggests that too much protein can increase the risk of developing heart disease, stroke, kidney stones and osteoporosis.
Neutralization Therapy Neutralization therapy is an extension of the provocation-neutralization testing procedure in which specified doses of allergen extracts are used by the patient to relieve symptoms. It is also called "symptom-relieving" therapy and "tolerance." Advocates recommend it for both treatment and prophylaxis.
Breast Cancer Facts and Statistics Breast cancer is the most common form of cancer in women. There are close to 200,000 new cases of breast cancer a year, and this results in about 47,000 deaths per year, although the mortality has fallen slightly in the 1990s.
The etiology of breast cancer remains unknown but at least two breast cancer genes have been cloned–the BRCA-1 and the BRCA-2 genes. Only about 10% of all breast cancers can be explained by hereditary mutations in these genes. Most of the sporadic cases, the other 90% of the cases of breast cancer, do not seem to have mutations in these genes so there does not seem to be a common pathway gene for both sporadic and hereditary cases.
Guidelines For Exercise In the Heat Guidelines for exercising in heat and humidity have been developed for road races, but these can be applied to any strenuous physical activity performed outdoors during warm weather. Ambient conditions are considered safe when the temperature is below 70º F and the humidity is below 60%. People who are sensitive to heat and humidity should reconsider exercising when the temperature is greater than 80ºF or the humidity is more than 60%. People who are in these conditions, but they should be aware of the potential hazards and take precautions to prevent heat illness.
The keys to exercising without incident in hot weather are to acclimate to the heat and maintain the body's normal fluid level. The major consequence of dehydration (excessive fluid loss) is a reduction in blood volume. This results in sluggish circulation that decrease the delivery of oxygen to the exercising muscles. Second, lowered blood volume results in less blood that can be sent to the skin to remove the heat generated by exercise. If too much of the blood temperature will rise, leading to to heat-stress illness. Hat illness is a serious problem that can be avoided by following a few guidelines deigned to preserve the body's fluid level.
