cardiac arrhythmia Adderall, the Wonder Drug or the Destroyer?

Why did the ADHD boy not introduce his girlfriend to any of his friends? He could not remember her name; or better yet, why would a chicken be considered ADD? It never gets all the way across the road because of all the distractions. Attention deficit-hyperactivity disorder (ADHD) is a developmental and behavioral disorder that affects 3 to 5 percent of all school-age children. The American Psychiatric Association explains that, "Individuals with ADHD may know what to do but do not consistently do what they know because of their inability to efficiently stop and think prior to responding, regardless of the setting or task" (Berne 2).
ADHD is believed to be caused by abnormalities in the dopamine neurotransmitters in the brain (Berne 4). The symptoms of ADHD include inattention, impulsiveness and hyperactivity that are inappropriate for a person's age level. In other words, the patient's brain is like a light constantly going off and on at the worst possible times. Although there is no cure for ADHD, treatment can help control symptoms. Stimulant therapy is the most commonly used type of treatment. These drugs improve ADHD symptoms in 70 percent of adults and 70-80 percent of children shortly after starting treatment (ADHD 3). Adderall RX, or its formal name of Methylphenidate, is the most common form of treatment for ADHD. In an article by Dr. Phillip W. Long, he states that, "The mode of action in man is not completely understood, but methylphenidate presumably activates the brain stem arousal system and cortex to produce its stimulant effect."
Those who take Adderall have mixed emotions about the drug. When used in school and work it allows them to concentrate and focus on what should be done. For instance Jenny Pearcy a user of Adderall for several years said, "I use to be a troubled student. I use to have consent run-ins with the law. Things never came easy to me and far too often they never came at all. Adderall was like putting on a pair of glasses worn by Superman. Suddenly everything became focused and organized." However there are several side effects of this drug such as severe weight loss and nausea. Constant headaches and sleeplessness have also been noted. Heart palpitations, cardiac arrhythmia, blood pressure and pulse changes are serious heath risks that can occur using Adderall. Adderall changes the personality of the person making them very bland. Most of the side effects are not hard to cope since the benefits are so high but the question of is the drug worth it and could I get this far without constantly arises from its patients.
Over five million children in the United States alone are prescribed Adderall to treat ADHD (Sturdy 44). That is about three to five percent of all American school children prescribed to the drug. Is Adderall or similar drug treatments necessary to treat ADHD? No, Dr. Edward Hallowell writes that having ADHD is not necessarily a bad thing. "Often these people are highly imaginative and intuitive. They have a "feel" for things, a way of seeing right into the heart of matters while others have to reason their way along methodically." As for treating ADHD, he says that the simple knowledge that there is a problem can be enough to improve the situation (Garber 56). Modifying the learning environment has been used as an alternative treatment. Simple changes like removing distractions, having directions explained better, or extending testing time can work as well as medication. Others have turned to the help of psychiatrists for counseling. They can help teach a child how to overcome the obstacles of ADHD. Since it is the doctors who diagnose ADHD, It has been my feeling that they prefer to treat it with what they understand, medicine. Non-drug alternatives are out there and they seem to have worked for some people. They can be costly and time consuming and not show any signs of improvements. Then again, Adderall is the same way.
Adderall has worked for thousands of people. Unfortunately they do not know about the alternatives such as removing artificial colorings and flavorings from food and beverages, making environmental modifications to improve functioning, or altering ... more

What is MTBE and Why we should be Concerned !!
     MTBE stands for Methyl Tertiary Butyl Ether.  In 1990 congress passed the Clean
Air Act to reduce smog in cities that were listed as ozone non-attainment area.  Congress mandated Reformulated Gasoline (RFG) as part of the act.  Congress mandated as part of it formula, a 2% by weight oxygenate to be added to RFG to reduce hydrocarbon SMOG pollutants from automobile exhaust emissions.
     MTBE is a chemical, which promotes more complete combustion by adding oxygen to gasoline.  This increases the temperature at which gasoline burns in the engine and reduces the amount of harmful vehicle exhaust emissions, such as carbon monoxide, nitrogen oxides, and hydrocarbons.  MTBE is manufactured by combining isobutylene (a waste product in the gasoline refining process) and methanol (produced from natural gas).  It is a colorless flammable liquid at room temperature with turpentine like color.
     MTBE evaporates quickly from surface water, soil or open containers.  MTBE is not expected to persist in the atmosphere because of its rapid reaction with hydroxyl radicals and its degradation by sunlight.   However, it may also contribute to the formation of photochemical smog when it reacts with other volatile organic compounds in the atmosphere.  Once in the air, MTBE can mix with precipitation that can eventually carry MTBE to groundwater or surface water.
     MTBE is highly soluble in water and very mobile in the subsurface.  It enters groundwater quickly because it does not bind well with soil and persists due to a lack of anaerobic or aerobic biodegradation.   Water supplies view MTBE as the most menacing ingredient of gasoline leaked from underground fuel storage tanks.  That’s because it travels faster in water underground and is longer lived.  And water treatment plants aren’t equipped to remove the contaminant, which imparts an unpalatable solvent like taste and odor in drinking water at minute concentrations.  However, this is a low potential for bioconcentration in plants or animals according to the U.S. EPA studies. Though studies have found that MTBE and ethanol by themselves do little to clean the air, and scientists have noted that they both indirectly help the cause by diluting concentrations of cancer causing benzene and the most potent forms of hydrocarbons that lead to smog.
      The major metabolites of MTBE are tertiary butyl alcohol (TBA) and formaldehyde.  Formaldehyde is further metabolized to formic acid and carbon dioxide, with the possible formation of methanol.  Formaldehyde is known to be both toxic, potent sensitized and may cause reproductive disorders.  
     The most commonly reported physical symptoms following MTBE exposure include:
Headache, nausea, dizziness, sore throat, drowsiness, disorientation, skin rashes and irritation, visual impairment, nosebleeds, diarrhea, insomnia, cough lethargy, malaise, muscle aches and cardiac arrhythmia.  Some people notice these effects while filling up at the pump, while driving their car, or simply by breathing urban air.  Currently, the EPA classifies MTBE as a possible human carcinogen.  Although acute low level exposures to MTBE do not appear to be very hazardous, questions have been raised concerning the potential risk of can upon chronic exposure to MTBE.  An EPA study of the carcinogenic effects of inhaled MTBE in mice and rats resulted in increased incidence of liver and kidney cancer.  Many researchers have correlated the increase in childhood and adult asthma, attention deficit disorder (ADD), and colds with the used of MTBE gasoline.  MTBE and its metabolites irritate the mucous membrane which, coupled with induced sensitization, may weaken out ability to resist infection.  Others have concluded that the rise in ADD among children is related to the neurological effects of MTBE resulting in difficulty concentrating and lightheadedness.
Summary: at current levels of 15 to 20% in RFG
 MTBE is having very little if any effect in reducing SMOG
 MTBE is actually contributing to the SMOG problem
 MTBE is water soluble, leachable and is contaminating water supplies nationwide
 MTBE is degrades into TBF which is highly and acutely toxic
 MTBE is causing adverse health effects like increased rates in asthma, especially children, it cities where it is being used
 MTBE as a oxygenate, is serving no useful purpose to society except to line the pockets of a few chemical manufactures at the expense of the American public
