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.

Myelodysplastic syndromes (MDS) is a term for a group of disorders that cause the bone marrow to produce an inadequate number of healthy blood cells — red blood cells, white blood cells and platelets. In MDS, cells in the bone marrow responsible for making blood cells (stem cells) don't mature, don't make enough blood cells or make defective cells.
Myelodysplastic Syndrome Treatment
The prognosis depends on the following:
Whether the myelodysplastic syndrome occurred after chemotherapy or radiation therapy for another disease.
The number of blast cells in the bone marrow.
Whether one or more types of blood cells are affected.
Certain changes in the chromosomes.

The Foetal Circulation To understand the foetal circulation, it must be appreciated that the foetus develops its own blood and that at no time does the foetal and maternal blood mix unless some pathological process is present. The foetus produces its own red and white blood corpuscles. During intrauterine life the foetal gastrointestinal and respiratory system are not functioning, so the maternal blood furnishes the necessary nutrients and oxygen through the placenta, which in this case acts as the organ of respiration.
Allergic Headache Certain types of headache are allergic in origin. In these cases patients develop headaches of variable severity when exposed to substances to which they are allergic. These may be food or inhalants. The symptoms vary with the person. As a rule, the pain is deep and sometimes throbbing, or it may acquire the characteristics of so-called sick headache or migraine. Not all instances of migraine are allergic in nature. When one realizes that chronic headache interfere with the patient's happiness and productivity, a serious effort must be made in each case to discover it cause. It must by no means assumed that every case of headache is allergic, because most frequently the cause of headache is something other than allergy. In the case of chronic recurrent headache one must always rule out some serious systemic condition like kidney disease, anemia, infection, or brain
Hiatus Hernia Treatment The term hiatus hernia describes diaphragmatic hernia or weakness in the diaphragm, the horizontal muscular wall separating the organs of the chest from the organs of the abdomen. A hernia is an abnormal protrusion of an organ or tissue through an opening. A hiatus, or opening, permits the esophagus to carry food from the mouth to the stomach. Blood vessels and nerves also pass through the diaphragm. The diaphragm is an important group of muscles for contracting and expanding the lungs, forcing air in and out of the lung tissues.
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.
What are Liver Disease Symptoms Liver disease (also called hepatic disease) is a broad term describing any single number of diseases affecting the liver.Hepatitis, inflammation of the liver, caused mainly by various viruses but also by some poisons (e.g. alcohol), autoimmunity (autoimmune hepatitis) or hereditary conditions.

Two HPV vaccines are currently on the market: Gardasil and Cervarix.
Both vaccines protect against the two HPV types (HPV-16 and HPV-18) that cause 70% of cervical cancers, and cause most HPV-induced genital and head and neck cancers. Gardasil also protects against the two HPV types (HPV-6 and HPV-11) that cause 90% of genital warts. In addition, Gardasil has been shown to prevent potential precursors to anal, vulvar, vaginal, and penile and head and neck cancers. HPV vaccines are expected to protect against HPV induced cancers of these areas as well as HPV induced oral cancers.

Type 2 diabetes, which is far more common, occurs when the body becomes resistant to the effects of insulin or doesn't make enough insulin.
How Is Allergy Produced, Role Of Contact Previous contact with or to a substance is necessary in order for a person to develop allergy to that substance. Such contact is not always easily demonstrable. For example, one may question the occurrence of previous contact in the case of baby who develops hives, eczema, or asthma upon ingesting cow milk for the first time. However, it may be demonstrated that the contact which produced sensitivity occurred before the baby as bon and was caused by enough the placental circulation. That contact plays a role in the development of allergy is demonstrated by the fact that allergic individuals living in Europe where there is no ragweed pollen never develop sensitivity to this pollen. In the same way there is no sensitivity to poison ivy among Eskimos who are not exposed to poison ivy.
