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.
Prostate Cancer Symptoms in Men What is prostate cancer?
Prostate cancer is a malignant (cancerous) tumor (growth) that consists of cells from the prostate gland. Generally, the tumor usually grows slowly and remains confined to the gland for many years. During this time, the tumor produces little or no symptoms or outward signs (abnormalities on physical examination).
What is lisfranc injury and how to recovery A Lisfranc (midfoot) injury is a significant injury that often has a prolonged recovery time. Fracture of the midfoot bones and/or disruption of the midfoot ligaments (Figure 1) leads to pain, swelling, and often an inability to weight-bear. During normal standing and walking the ligaments of the midfoot are subject to forces that are 2-3 times body weight.
Backache Symptoms, Treatment and Prevention A backache is generally a gripping pain near the inward curve of the back above the base of the spine. It is one of the most common physical ailments, affecting about 80 percent of the population at some time in their lives.
Pain results from a variety of causes. Strains are especially under exercised back muscles perform beyond their normal capacity. The muscles will then contract or go into spasm and become a tight mass of tissue. Meanwhile, the body transmits a sharp pain signal as nearby muscles tighten in an effort to protect strained muscles and prevent further damage. Strain of back muscles can be due to participation in a sport, a sudden jerking motion (such as a car braking), or reflex actions like sneezing.
Medical abbreviations list Are you looking for medical abbreviations list?
Abbreviations are used very frequently in medicine. They boost efficiency as long as they are used intelligently. The advantages of brevity should be weighed against the possibilities of crypticness (making the communication harder for others to understand) and ambiguity (having more than one possible interpretation). Certain medical abbreviations are avoided to prevent mistakes, according to best practices (and in some cases regulatory requirements); these are flagged in the list of abbreviations used in medical prescriptions.
Heat Stroke Treatment and Medication at Home Heat stroke may also be referred to as: heat contractions, sunstroke, heat exhaustion and heat fatigue. This health state is often life-threatening. This situation occurs when people exert or play in scorching, sticky places and their body liquids are lost during sweating, causing dehydration the body to swelter. Heat sickness may be observed as an array of illness involving the body’s failure to deal with heat. Here is some stuff about Heat Stroke Treatment at Home
Cold Sore Treatment Over the Counter Are you looking for cold sore treatment over the counter?A cold sore and a canker sore can come from the same herpes simplex virus, but they aren't the same thing. A cold sore is a small- to medium-size blister that appears on or around the mouth area. Cold sores can also appear in the nose. A canker sore is a virus-induced blister that is on the inside of the mouth. It usually takes 2 days to 2 weeks to heal. A cold sore, besides being red and painful, can also leak fluid.
Aneurysm Symptoms and Treatment An aneurysm is a bulge in a blood vessel, usually an artery, due to a weakness in the vessel wall, particularly in the elastic, muscular middle layer of the artery wall. An artery has three layers: the intima, which is the smooth inner layer; the media, or middle layer; and the adventitia, which is the tough outer layer. A true aneurysm involves all three layers, whereas a false aneurysm is a disruption or clot in one or two of the layers, causing a bulge in the vessel. A dissecting aneurysm occurs when blood separates the layers, thereby creating an extra channel, sometimes extending the full length of the artery, through which blood flow is diverted from the organs or tissues served by the blood vessel. This dangerous condition can develop in a matter of hours a day.
The main danger of most untreated aneurysm is that they may rupture, causing death due to loss of blood. Even if death does not occur, blood loss may so decrease blood flow to the heart that it cannot work properly.
Symptoms of endometriosis Are you looking for symptoms of endometriosis? here is some good article about symptoms of endometriosis.
Ten percent of women will develop endometriosis, characterized by the presence of endometrial tissue at sites outside the uterine cavity. The ectopic endometrial cells cause cyclical dysmenorrhea. The most common sites are the ovaries, posterior cul-de-sac, uterosacral ligaments, posterior broad ligament, and anterior cul-de-sac. The uterine serosa, rectovaginal septum, cervix, vagina rectosigmoid, and bladder are less frequent locations.
Whole food diet plan and recipes A whole foods diet is a basic, simple way of eating that is just as it sounds. Meals in the diet are composed of whole foods that are unprocessed or as minimally processed as possible. Another way of defining a whole food is put forth by Beatrice Trum Hunter, author of "A Whole Foods Primer." Hunter says that whole foods have "nothing added and nothing taken away." That is, they are as close to their natural state as possible. The School of Medicine at Texas Tech University suggests that whole foods diets are especially suitable for people with obesity or hypertension.
Nervous System, Digestive System and Circulator System Nervous System
The body is provided with a sturdy frame in the form of a bony skeleton and hundreds of muscles are arranged in and around the body framework to provide a means of movement. This entire mechanism would be useless without some centralized means of control and coordination.
The human body depends upon its nervous system to control, regulate, and stimulate the many parts of the human machine.
Anemia Symptoms in Women and Pregnancy Anemia is common among women, in both the obstetric and the primary care settings. It is not a disease in and of itself, but it indicates the presence of an underlying disorder, such as an occult malignancy, nutritional deficiency, or bleeding, that must be sought out and effectively treated.
Anemia is a decline in erythrocyte mass from any etiology and is generally defined as a hematocrit or hemoglobin value that is two standard deviations below the mean for a given population. Specifically, in women, a hemoglobin value less than 12 g/dL (or less than approximately 11 g/dL in pregnancy) is generally considered consistent with anemia. The lowered norms in pregnancy occur because of a "physiological anemia" as a result of the disparate rise in the plasma and erythrocyte volumes. The norms for hemoglobin among those of African descent are 1 g/dL lower.
Physical Allergy Some persons, when exposed to changes in temperature such as cold or heat or when exposed to sudden effort or sunlight, may develop manifestation, such as asthma, hay fever, or hives. In these instances the cold or heat acts as an antigen, much the same as milk or pollen may produce allergy. The demonstration of the presence of such sensitivity requires special tests. In the case of a patient sensitive to cold one tests the patient by attaching a small tube containing ice water to the skin of the arm. The tube is held in place with adhesive. Sensitivity to cold is determined by the appearance of large welt or hive at the point of contact. A similar of allergy are also included those patients who when exposed to a draft or a cod breeze develop nasal symptoms followed by severe so-called sinus headaches.
Chlamydia Symptoms and Treatment for Men Chlamydia is a bacterial infection disease transmitted when people have sexual relations. It is the most common sexually transmitted disease (STD) in the United States, with over 2.8 million affected individuals each year. Among adults, about 5% of the population is estimated to be infected. Among sexually active adolescent females, about 10% are infected.
