  • The Psychological And Physical Aspects Of Drug Abuse In Today's Adolescence - 1,423 words
    "The Psychological And Physical Aspects Of Drug Abuse In Today'S Adolescence" "The psychological and physical aspects of drug abuse in today's adolescence" Unfortunately the abuse of illegal drugs is not uncommon in today's adolescent communities. Many teenagers today use illicit drugs as a way to deal with everyday pressures such as school, after school jobs, sports activities, domestic violence and peer pressure. Adolescence has been found to be a period of weakening bonds with parents and strengthening bonds with peers (Flay, 1994). Numerous states have experienced an increase in drug related deaths (http://www.usdoj.gov/dea/stats). More than 1 in 10 of today's youth aged 12-17 were curre ...

  • Abortion - 685 words
    Abortion Abortion is one of the most controversial issues in the United States today. One out of every three pregnancies never come to term because a woman has an abortion (Flanders 3). It is understood that a new individual human begis growing in the mothers uterus at fertilization (When Does Life Begin). The term abortion refers to any premature expulsion of a human fetus. Approximately 93 percent of all induced abortions are done for elective, non-medical reasons. In 1973, the Supreme Court handed down Roe v. Wade ad Doe v. Bolton decisions legalizing abortion in all 50 states during all nine months of pregnancy, for any reason, medical, social, or otherwise (Abortion: Some Medical Facts) ...

  • Abortion And Murder - 1,060 words
    Abortion And Murder On January 22, 1973, the U.S. Supreme Court, in two separate decisions, Roe v. Wade and Doe v. Bolton, declared that Congress and the states had to adopt a policy on abortion. Since then, abortion has been one of the most controversial issues in our country today. Every time the subject of abortion is raised, the same question always comes up: should people have the right to terminate an unborn child? The answer is no. No person should have the right to terminate an unborn child which has not yet had the chance to live, no matter what the reason is. Abortion is the termination of an alive, unborn child, which can experience pain through the process of an abortion. There i ...

  • Abortion Is Not Bad - 845 words
    Abortion Is Not Bad Abortion is not bad, rather it is your logic and argumentation that is lacking in ability and understanding. First, you argue that the presence of a beating heart alone necessarily qualifies a fetus as being a living human being that is entitles to a right to life. While on its face this argument may initially appear compelling, it is profoundly lacking in scientific substantiation. A fetus during the first trimester of development may have a small impulse that resembles a heart beat, but it completely lacks both a brain and a central nervous system. In fact, a spider or a fly is much more developed (and has the capacity to feel more pain) than a fetus early on in the sec ...

    ... get a BAC that high? A 160 pound man will have a BAC of about .04, 1 hour after consuming two 12-ounce beers on an empty stomach. Your BAC will depend on how much you weigh, how much you drink, amount of time since your last drink and your gender. Women metabolize alcohol differently from men, causing women to reach higher BAC's at the same doses. Recent research is showing that true substance dependence may be caused, in part, by brain chemistry deficiences. That is one reason that substance dependence is considered a disease. And, as with other diseases, there is the possibility of taking medicine to get better. There is now promising evidence that taking medicine can correct some of ...

When sugars from the fruits or grains are combined with yeast and water, alcohol results. Alcohol is a drug and, like all drugs, it has an effect on a persons body and mind. Because drinking alcoholic beverages makes some people feel more alive and more outgoing, alcohol is sometimes seen as a stimulant.

  • Alcoholismnature Or Nuture - 1,645 words
    Alcoholism-Nature Or Nuture? INTRODUCTION: Alcoholism can affect anyone. It has enormous costs as it pertains to societies, families, and individuals. It is not prejudicial towards any race, color, sex, religion, or economic level. Although we do have ideas as to what alcoholism is, what we do not know is the exact cause(s) of this problem. Researchers are continually seeking answers to the long-standing nature versus nurture debate. Different views are split between a biological paradigm and a physchological paradigm. No one explanation seems to be better than another is. I will present views of the effects alcoholism has on society and an insight to the factors that serve to fuel the natur ...

  • Alcoholosm - 1,240 words
    Alcoholosm Within the context of our society, drinking of alcohol is a perfectly normal activity. For most people drinking a moderate amount of alcohol can be beneficial, indeed studies suggest that moderate drinking may protect against coronary heart disease by improving insulin resistance (Gold, 1991). However, for a minority of people drinking alcohol is an activity that is fraught with danger and, for a very few, is akin to taking a poison that will almost inevitably ruin their lives. Henceforth, it is important for research purposes to define who an alcoholic is and what the effects of alcohol on that person are. An alcoholic is a person who drinks excessive amounts of alcohol habituall ...
