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.

Tinnitus Treatment Homeopathic Tinnitus is the perception of sound within the human ear in the absence of corresponding external sound.
Tinnitus is not a disease, but a symptom that can result from a wide range of underlying causes: abnormally loud sounds in the ear canal for even the briefest period (but usually with some duration), ear infections, foreign objects in the ear, nasal allergies that prevent (or induce) fluid drain, or wax build-up. Withdrawal from a benzodiazepine addiction may cause tinnitus as well. In-ear headphones, whose sound enters directly into the ear canal without any opportunity to be deflected or absorbed elsewhere, is a common cause of tinnitus when volume is set beyond moderate levels.

Recognizing Warning Signs of Stroke Stroke is a general term for a wide variety of crises (sometimes called cerebrovascular accidents [CVAs] or brain attacks) the result from blood vessel damage in the brain. African Americans have a much greater risk of stroke than white American do, probably because African Americans have greater likelihood of having hypertension than white Americans. Data for 1998 indicate that 158,448 deaths and half a million new cases of stroke occurred. Just as the heart muscle needs adequate blood supply, so does the brain. Any disturbance in the proper supply of oxygen and nutrients to the brain can pose a threat.
Perhaps the most common form of stroke results from the blockage of a cerebral (brain) artery. Similar to coronary occlusions, cerebrovascular occlusions can be started by a clot that travels from another part of the body to the brain, called an embolus. The resultant accidents (cerebral thrombosis or cerebral embolism) cause between 80% and 90% of all strokes. The portion of the brain deprived of oxygen and nutrients can literally die.
Downs syndrome Symptoms and Prevention Down’s syndrome is a congenital (present at birth) disorder characterized by varying degrees of mental retardation and a variety of physical abnormalities.
Down’s syndrome Causes
Normally, each cell in the human body has 46 chromosomes; the cells in someone with Down’s syndrome, however, have 47. In ways that are as yet unknown, the presence of the extra chromosome causes all of the unusual characteristics of Down’s syndrome. In 95 percent of cases, the condition is called trisomy 21 (because the extra chromosomes is attached to the twenty-first pair of chromosomes), and the mistake in genetic coding is one that apparently could happen to anyone. In five percent of cases, the syndrome is caused by a defect that is believed to run in families.
Symptoms of Gallbladder Dysfunction Are you looking for symptoms of gallbladder dysfunction? What is important to say when it comes to gallbladder symptoms is that people can be quite unaware that their digestion problems actually come from their gallbladder. The reason for this is that gallbladder symptoms are closely related to other signs of digestion disorders. So keep in mind that all the symptoms you find here may be related not only to your gallbladder but to other organs as well. Sometimes only one of these symptoms is enough to show you that something is wrong with your gallbladder. So if you experience one of the symptoms listed below (or more of them), visit your doctor.
In vertebrates the gallbladder (cholecyst, gall bladder, Biliary Vesicle) is a small organ that aids mainly in fat digestion and concentrates bile produced by the liver. In humans the loss of the gallbladder is usually easily tolerated.
Chicken Pox Causes, Symptoms, Complications, Treatment and Prevention Chicken pox is an extremely contagious disease that is characterized by a blistery rash. It occurs most frequently in children between the ages of five and eight; less than 20 percent of the cases in the United States affect people over 15 years old. Chicken pox is transmitted so easily that most everyone gets the disease at some time.
Chicken Pox Causes
Chicken pox is caused by infection with the varicella zoster virus. Chicken pox is contracted by touching an infected person’s blisters or anything that has been contaminated by contact with them. The virus also thought by some researchers to be air borne, since it may be caught from an infected person before the rash develops. Another way to get chicken pox is by exposure to shingles, a localized rash caused by the same virus.
The incubation period (the time between exposure to the illness and the appearance of symptoms) of chicken pox is 10 to 21 days. It is contagious for about six to eight days after day rash appears or until all of the blisters have dried out.

Spinal Stenosis Definition and Treatment What is defintion of Spinal Stenosis. Spinal stenosis is a narrowing of one or more areas in your spine — most often in your neck or lower back. This narrowing can put pressure on the spinal cord or spinal nerves at the level of compression. Stenoses of the vascular type are often associated with unusual blood sounds resulting from turbulent flow over the narrowed blood vessel. This sound can be made audible by a stethoscope, but diagnosis is generally made or confirmed with some form of medical imaging.
aortic stenosis (AS) a narrowing of the aortic orifice of the heart or of the aorta near the valve.
hypertrophic pyloric stenosis narrowing of the pyloric canal due to muscular hypertrophy and mucosal edema, usually in infants.
Diet for Diabetics Type 1 Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin, a hormone needed to allow sugar (glucose) to enter cells to produce energy. 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.
