.... first brain cell. The signal is called a neurotransmitter. One major neurotransmitter is called dopamine, which is involved in feelings of pleasure. When the drug is released into the brain, it blocks the dopamine from returning to the first brain cell. Repeated use changes the brain cells so that normal messages can't be sent between brain cells. The drug must always be present in order for neurotransmissions to take place. The user is only able to feel pleasure from the cocaine rather than the things he/she used to find pleasurable. This is called drug addicti .....

.... tolerant of unruly behavior. Some local school offices have become virtual noon-time pharmacies. At one Ottawa-area board of education, the number of medications dispensed to students by office administrators has increased 20 per cent over the past 18 months. A good chunk of those pills are Ritalin. "We always worry that we're a half-step away from giving someone the wrong dosage," says John Beatty, the board's superintendent of school operations(Ritalin Boy). "In certain school systems there's been a teacher who has seen it work and they'll start .....

.... for his people to take the victory away from the Romans by robbing them of their glory. Eleazar's plan was a success and history may well justify the act of suicide. I talked to both my parents and asked them what they would do in this situation. My mom felt that it was wrong to commit suicide in this case because the Jews didn't even try to put up a fight. As she put it, "Even if the Jews did lose, their lives may have been spared." My dad felt that suicide was the best thing to do given the circumstances In the Bible, Mark 14:32-42 deals with Jesus willful .....

.... drugs regulated by the Drug Enforcement Administration (DEA). However, the medical use of marijuana has been gaining respectability. Several states have research programs of their own and some governors, including Republican William Weld of Massachusetts, openly endorse medical legalization. The editor of the prestigious New England Journal of Medicine, Jerome Kassirer, lambasted the Clinton administration in an editorial entitled, "Federal Foolishness and Marijuana," that received national attention. "To prohibit physicians from alleviating suffering by pr .....

.... to grow their own supply of tobacco. They started growing up to 100,000 pounds of tobacco a year! At this rate, the figure of tobacco got to be as high as 100 million pounds by the time of the American Revolution. In the 17th century, cultivating tobacco became the most important industry of the Virginia and Maryland colonies. Sometime later it became the major industry in North Carolina. “The first of the tobacco manufacturers to mass-produce cigarettes was Washington, Duke and Sons of Durham, North Carolina (Theodore, 77).” Tobacco is a highly add .....

.... any race, and ethnic groups. This disease hits the elderly the hardest, because they don't really have anyone to take care of them. And somethimes they get forgetful and don't take medication or their insulin shots. Heres a question "What is ?"

.... reportedly admired Aristotle's assertion that dreaming is the activity of the mind during sleep (Fine, 1973). It was perhaps the use of the term activity that Freud most appreciated in this brief definition for, as his understanding of the dynamics of dreaming increased, so did the impression of ceaseless mental activity differing in quality from that of ordinary waking life (Fine, 1973). In fact, the quality of mental activity during sleep differed so radically from what we take to be the essence of mental functioning that Freud coined the term "Kin .....

.... smoker's attention becomes increasingly focused on cigarettes. Nicotine causes smokers' brain cells to grow more nicotinic receptors than normal; therefore, the brain may function normally despite the irregular amount of acetylcholine-like chemical acting upon it. The brain is reshaped: the smoker feels normal with nicotine in his system, and abnormal without it. A series of tests were conducted on nonsmokers, "active" smokers, and "deprived" smokers. The "active" smokers were given a cigarette before each test, while the "deprived" smokers were not allowed .....
