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.

Local Treatment of Allergic Dermatitis Most Persons who suffer with allergic dermatitis have accumulated numberless lotions, salves, ointments, and other local preparations. These have either been prescribed for them or suggested to them by their family or friends. For the most part, the effects of these long-continued local applications is to further irritate and traumatize the skin, so that in the end more harm than good is done. First take away all these various drugs and prescribe only such bland preparations as are least likely to injure the skin. These must be cautiously and carefully applied, observing their changing effect. Indeed, at times it is necessary to use the preparation of one area of the skin only, such as one arm or one leg, and observe the difference between the dermatitis on that are and on the area of the body where no preparation has been used.
Pulmonary Embolism Symptoms and Prevention Pulmonary embolism is a condition in which a part of blood clot in a vein breaks away and travels through the heart and into the pulmonary circulatory system. Here the vessels leading from the heart branch like a tree, gradually becoming smaller until finally they form capillaries, the smallest blood vessels. Depending on its size, the clot will at some point reach a vessel through which it cannot pass, and there will lodge itself. The clot disrupts the blood supply to the area supplied by that vessel. The larger the clot, the greater is the area of lung that loses its blood supply, and the more drastic the results to the patient.
Erythema Multiforme and Stevens Johnson Syndrome Erythema multiforme (EM) is an acute hypersensitivity reaction characterized by distinctive skin lesions and mucous membrane involvement that has a spectrum of severity. It occurs in two forms: the more common "minor" type and the more severe "major" type, also called Stevens-Johnson syndrome (SJS). Sometimes EM includes toxic epidermal necrolysis (TEN) or Lyell disease. EM minor first was described completely by von Hebra in 1866; Stevens and Johnson described the major variant in 1922. EM occurs more often in males, and 20% to 50% of cases occur in the pediatric age group, although rarely in those younger than age 3 years. A winter predominance is suggested.
The pathologic process responsible for EM is unknown. A review of the literature generates an extensive list of causative or inciting agents. Most frequently mentioned are sulfonamide antibiotics and anticonvulsants, both used commonly in pediatric practice. Malignancies, radiotherapy, autoimmune diseases, and infectious agents such as mycoplasma also have been implicated as possible causes. In 1992, Weston et al described a high incidence of herpes simplex virus (HSV) in EM lesions among both adults and children with or without a preceding history of HSV infection.

Open heart surgery Are you looking for about open heart surgery? Open heart surgery is a surgery in which the patient's heart is opened and surgery is performed on the internal structures of the heart. It was soon discovered by Dr. Wilfred G. Bigelow of the University of Toronto that the repair of intracardiac pathologies was better done with a bloodless and motionless environment, which means that the heart should be stopped and drained of blood. The first successful intracardiac correction of a congenital heart defect using hypothermia was performed by Dr. C. Walton Lillehei and Dr. F. John Lewis at the University of Minnesota on September 2, 1952. The following year, Soviet surgeon Aleksandr Aleksandrovich Vishnevskiy conducted the first cardiac surgery under local anesthesia.
The Lymphatics, Respiratory System and Skin The Lymphatics
A large part of the human body is composed of the connective tissue. Within this connective tissue are the lymph cells and the walls of the lymph vessels. The connective tissue is concerned in the formation of blood and blood vessels and also in the formation of lymph vessels.
Through the lymph vessels the white blood cells, which pick up waste material from the body, travel carrying the remains of dead tissue and foreign bodies. The lymph capillaries correspond also to the blood capillaries, the tiniest vessels which form the connection between the arterial and venous blood systems.
