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.
Atherosclerosis (Hardening of the Arteries) Definition and Causes What is Atherosclerosis definition? Atherosclerosis is a disease caused by the deposit of fat into the walls of blood vessels, especially the arteries. The disease can occur in any artery, but usually it is found in larger arteries around areas where they branch. One of the most common sites of atherosclerosis is the coronary arteries supplying the heart tissue. When atherosclerosis occurs in the coronary arteries, it is referred to as coronary artery disease.
Atherosclerosis can occur in anyone, but it is more likely to affect males, smokers, persons with high blood cholesterol levels or high blood pressure, and people who don't exercise frequently. Before age fifty, women develop atherosclerosis far less frequently than do males, because the hormone estrogen has a protective effect against the disease. After menopause, however, women are just as likely to develop atherosclerosis as men are. Those women who take supplemental estrogen after menopause retain some of the hormone's protective effects, however.
Atherosclerosis begins as small streaks of fat deposited just underneath the smooth lining of the arteries. The streaks, which usually begin near points where the arteries branch, can be found in some people as early as their late teens. As time passes, the streaks become thick accumulations of fat, known as plaques. There may be calcium deposits within the plaques, or the plaques may erode through the inner lining of the artery and project out into the lumen, the center of the vessel.
Symptoms of Angina and Treatment with Healthy Food and Diet Angina is often experienced as a pain in the chest, frequently after running
up a flight of stairs, but in extreme cases after getting out of a chair. It is
brought on by an in adequate supply of oxygen via the blood to the heart muscle.
Over many years, arteries begin laying down sticky deposits, which harden and
eventually cause a narrowing within the blood vessels.
Typical symptoms include pain in the centre of the chest, which
sometimes spreads to the neck/jaw area and down the left arm. The pain may also
be accompanied by breathlessness, feeling faint, sweating and/or nausea. If you
have these symptoms, seek medical attention as a matter of urgency.
How HIV Is Transmitted HIV typically enters one person’s body when another person’s infected body fluids (semen, vaginal secretions, blood, etc.) gain entry through a breach in body defenses. Mucous membranes of the genital organs and the anus provide the easiest route of entry. If there is a break in mucous membranes (as can occur during sexual intercourse, particularly anal intercourse), the virus enters and begins to multiply.
Natural cure for leukemia Are you looking for Natural cure for leukemia? Leukemias are grouped by how quickly the disease develops (acute or chronic) as well as by the type of blood cell that is affected (lymphocytes or myelocytes). The four main types of leukemia include acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myelocytic leukemia (AML), and chronic myelocytic leukemia (CML). But most people who have these risk factors don't get leukemia. And most people who get leukemia do not have any known risk factors.
Physical Allergy Some persons, when exposed to changes in temperature such as cold or heat or when exposed to sudden effort or sunlight, may develop manifestation, such as asthma, hay fever, or hives. In these instances the cold or heat acts as an antigen, much the same as milk or pollen may produce allergy. The demonstration of the presence of such sensitivity requires special tests. In the case of a patient sensitive to cold one tests the patient by attaching a small tube containing ice water to the skin of the arm. The tube is held in place with adhesive. Sensitivity to cold is determined by the appearance of large welt or hive at the point of contact. A similar of allergy are also included those patients who when exposed to a draft or a cod breeze develop nasal symptoms followed by severe so-called sinus headaches.
Bell Palsy Treatment Guidelines Bell's palsy is an idiopathic facial paresis that has been attributed to an inflammatory reaction involving the facial nerve. A relationship of Bell's palsy to reactivation of herpes simplex virus has recently been suggested, but there is little evidence to support this.
Cymothoa Exigua in Human and Life Cycle Cymothoa exigua is a tiny crustacean that sneaks up on a fish (specifically, a red snapper) and works its way in through the gills. Typical parasite behavior so far.
Then it attaches itself to the base of the fish's tongue, the tongue evidently being the tastiest part of the fish (get it!?). The parasite uses its claws to dig into the tongue and drink the fish's blood--and that's just the beginning
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.
Echocardiographic diagnosis in carcinoid heart disease W.F. Wonnink-de Jonge, C.T.A.M. Knibbeler-van Rossum, C. van der Heul, W.H. Pasteuning 181
In this case report the typical echocardiographic features
of carcinoid heart disease are presented. Newer treatments
such as the use of a somatostatin analogue, interferon and
hepatic de-arterialisation have improved the prognosis in
patients with carcinoid syndrome. Nevertheless this syndrome
portends a poor prognosis in patients with cardiac
involvement. Cardiac lesions are mainly located in the
right side of the heart.
Acute idiopathic thrombocytopenic purpura in adults following viral infection A.J. Kooter, P.W.G. van der Linden, G. de Klerk 174
Idiopathic thrombocytopenic purpura (ITP) can follow a
viral infection. We describe severe thrombocytopenia in two
adult patients preceded by varicella zoster and Epstein-Barr
virus infection, respectively. The differences between acute
and chronic ITP are discussed, as well as therapeutic
Pseudogout crystals Pseudogout crystals are small enough and dull enough that they’re relatively difficult to see. Well, how do you see them? You take a pallet spin it down or take fluids spin it down to a pallet resuspend it, your chances of seeing pyrophosphate crystals go up about 70% or if you use a pallet. This is clinically an acute podagra. The inflammation is so intense that you actually peel off the skin like a blister. How come this is not cellulitis, sometimes it is difficult to sort out, as I say, the two can co-exist. The location is consistent with gout; in this particular case you can see tophaceous draining. This is chronic polyarticular tophaceous gout in a female patient that mimics rheumatoid arthritis. No history of acute podagra, this patient is 75 years of age, underlying osteoarthritis with crystal deposition disease. Different disease in men and women.
Heat Stroke Treatment and Medication at Home Heat stroke may also be referred to as: heat contractions, sunstroke, heat exhaustion and heat fatigue. This health state is often life-threatening. This situation occurs when people exert or play in scorching, sticky places and their body liquids are lost during sweating, causing dehydration the body to swelter. Heat sickness may be observed as an array of illness involving the body’s failure to deal with heat. Here is some stuff about Heat Stroke Treatment at Home
What is Pescatarian Definition and Recipes Are you looking for about what is pescatarian? and what are pescatarian recipes? A pescatarian is a person who refrains from eating land animals and birds, but includes fish, mollusks, and crustaceans in addition to fruits, vegetables, plants, legumes, nuts, and grains. This is a common form of “vegetarianism” and is generally considered a very healthy diet. It can also be a stepping stone to full vegetarianism. Pescatarians can enjoy lowfat protein sources that are high in fish oils, which contain Omega 3 fatty acids—the “good fats” that reduce inflammation.
