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.
Arteries of the Body Function and Pictures Arteries facts
Arteries are vessels that conduct blood away from the heart
Arteries transport oxygenated blood under pressure to the cells of the
body. (The pulmonary artery is an exception; it transports deoxygenated blood
to the lungs)
The arterial wall consists of three primary layers:
The innermost layer consists of simple squamous epithelium (the endothelium)
surrounded by a connective tissue basement membrane with elastic fibers.The
middle layer consists mainly of smooth muscle and is usually the thickest layer.
It not only provide support for the vessel but also changes vessel
diameter to regulate blood flow and blood pressure.The outermost layer,
which attaches the vessel to the surrounding tissue, consists of connective
tissue with varying amounts of elastic and collagen fibers.
What is Morgellons Disease Morgellons (also called Morgellons disease or Morgellons syndrome) is a name that was given in 2002 by stay-at-home-mom Mary Leitao to a proposed condition characterized by a range of cutaneous (skin) symptoms including crawling, biting, and stinging sensations (formication); finding fibers on or under the skin; and persistent skin lesions (e.g., rashes or sores).

Alternative Therapies for Asthma You probably have heard of several so-called "alternative" therapies for asthma. These are treatments that are not conventional and are usually given by nonmedical people. Most of these "treatments" do not help asthma and are often very expensive. However, people are sometimes tempted to try alternative therapy, which is often advertised by means of testimonials as having great benefit. People always hope that this will provide
a "cure" and allow them to stop their asthma treatments.
It should be stressed that these treatments have no proven benefit when tested in
proper clinical trials, although there may appear to be some improvement at first because
of the "placebo" effect, since suggestion may, for a short time, improve asthma symptoms.

Diverticulitis Diet Foods to Avoid A low residue diet is one that consists of a daily intake of no more than 10 grams of fiber. While on this diet for an extended period of time it is recommended that a multi-vitamin or mineral supplement be taken daily. This ensures that minerals and vitamins lost while on the low residue diet are made by taking supplements.
Until recently, many doctors suggested avoiding foods with small seeds because it was believed that particles could lodge in the diverticula and cause inflammation. However, this is now a controversial point and no evidence supports this recommendation. So the seeds in tomatoes, zucchini, cucumbers, strawberries and raspberries, as well as poppy seeds, which are part of your diverticulitis diet, are generally considered harmless.
