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.
Other Drugs Of Concern Drugs discussed in the following sections have been abused for many years. Unfortunately, some that had become less popular seem to be reappearing, along with a dangerous new generation of illicit drugs. Problems with any illegal drugs include "quality control". Because there is no federal regulation of these drugs and because people involved in transportation and distribution of illegal drugs are not always concerned with purity or quality, additives to any illegal drug may include dangerous and even poisonous substances. Also, it is frequently impossible to determine the potency of the drug. A very pure form of a drug can easily be lethal for an individual who has been using a form that has been "stepped on" and was less potent.

Cholera History Cholera has killed millions of people since it emerged out of the filthy water and living conditions of Calcutta India in the early 1800�s. Since then, there have been a total of eight cholera pandemics. A cholera pandemic is a cholera epidemic that can last many years or even a few decades at a time, and that spreads to many countries and across continents and oceans. The first cholera pandemic of 1817-1823 spread from India to Southeast Asia, Central Asia, the Middle East and Russia leaving hundreds of thousands of people dead in its wake. The recent cholera epidemic in Pohnpei, which was part of the eighth and current pandemic, added some more sad numbers to the tragic statistics of cholera. In this year, since January there have been cholera outbreaks in Peru, southern Africa and the Marshall Islands.
Listeria symptoms in adults and treatment Are you looking for listeria symptoms in adults? Listeriosis is a bacterial infection caused by a Gram-positive, motile bacterium, Listeria monocytogenes. Listeriosis is relatively rare and occurs primarily in newborn infants, elderly patients, and patients who are immunocompromised.
The symptoms of listeriosis usually last 7–10 days, with the most common symptoms being fever, muscle aches, and vomiting. Diarrhea is another, but less common symptom. If the infection spreads to the nervous system it can cause meningitis, an infection of the covering of the brain and spinal cord. Symptoms of meningitis are headache, stiff neck, confusion, loss of balance, and convulsions.
Food, Diet, and Asthma Patients with asthma often wonder whether the food they eat may make their symptoms worse. There is still much uncertainty about diet and asthma, and so confusing advise is often given.

Heat Stroke Long Term Effects Are you looking for heat stroke long term effects? here is some good article about heat stroke long term effects.
Heat stroke is a form of hyperthermia, an abnormally elevated body temperature with accompanying physical symptoms including changes in the nervous system function. Unlike heat cramps and heat exhaustion, two other forms of hyperthermia that are less severe, heat stroke is a true medical emergency that is often fatal if not properly and promptly treated.
Lupus Symptoms in Women Are you looking for Lupus Symptoms in Women? Lupus is a clinical syndrome, the cause of which remains uncertain. It is a member of the family of autoimmune rheumatic diseases. Lupus is more common in women, and certainly more common amongst the black and Chinese population. It’s clinical diversity is at least apparently matched by its serological diversity. The prevalence of lupus among Afro-Caribbeans is approximately five times that of a Caucasian population, and about 2 ˝ times that of an Asian population.
Symptoms bowel cancer Are you looking for symptoms bowel cancer? Colorectal cancer, commonly known as bowel cancer, is a cancer caused by uncontrolled cell growth (neoplasia), in the colon, rectum, or vermiform appendix. Colorectal cancer is clinically distinct from anal cancer, which affects the anus.
Colorectal cancers start in the lining of the bowel. If left untreated, it can grow into the muscle layers underneath, and then through the bowel wall. Most begin as a small growth on the bowel wall: a colorectal polyp or adenoma. These mushroom-shaped growths are usually benign, but some develop into cancer over time. Localized bowel cancer is usually diagnosed through colonoscopy.
Facing Cancer While heart diseases mortality rates have declined steadily over the past 50 years, cancer mortality rates have increased consistently in the same period. Based on current rates, about 83 million-or one in three of us now living-will eventually develop cancer. Many factors have contributed to the rise in cancer mortality, but the increase in the incidence of the lung cancer is probably the most important reason. Despite these gloomy predictions, recent advancements in the diagnosis and treatment of many forms of cancer have reduced much of the fear and mystery that once surrounded this disease.
Drug Classification Drugs are commonly classified according to the physiological effect they have. Categories include stimulants, depressants, hallucinogens, narcotics, and inhalants. Two other types are also important. First, designer drugs are manufactured to mimic the effects if drugs found in the previously mentioned categories. Designer drugs usually are not illegal because their chemical formula has been altered from the original drug. The other drug, marijuana, is difficult to classify but is usually included as a hallucinogen. Depending on the dose, marijuana can mimic a variety of substances found in other categories.
Cerebral Palsy Definition Sign and Treatment Cerebral Palsy Definition
Cerebral palsy (CP) is an umbrella term encompassing a group of non-progressive, non-contagious motor conditions that cause physical disability in human development, chiefly in the various areas of body movement.
Misophonia symptoms and treatment What is Misophonia definition? Misophonia – literally the hatred of sound -can be defined as a hypersensitivity to background sounds or visual stimuli that are generally ignored by other people. More importantly than the individuals inability to block out the offending stimuli or “trigger” is the acute negative emotional response experienced as a direct result of being in contact with a trigger.
Misophonia commonly occurs along with hyperacusis and/or tinnitus, but can appear by itself. One of the tools we use to treat misophonia at AC Associates is called Tinnitus Retraining Therapy (TRT). TRT recognizes the specific involvement of various components of the auditory pathways of the nervous system in occurrences of tinnitus, hyperacusis and misophonia. For treatment of misophonia, TRT uses a method based on the active removal of conditioned reflexive responses to sound, allowing patients to feel like themselves again.
