Drug Addiction Research Paper-35
Most of the information about how drugs make a person feel come from self-reports of licit and illicit users of drugs, whereas most of the data about how the body affects drugs and how drugs work in the brain comes from well-controlled experimental studies using nonhuman animals.

Bibliography A drug is a chemical substance produced exogenously (outside of the body) that, when taken into the body, changes normal body functions.

Inhalation results in fast absorption into the bloodstream because gases and drugs in smoke (e.g., nicotine) are readily absorbed into the intricate network of capillaries that line the large surface area of the elaborately pocketed lungs.

Drug abuse, which also can occur with licit and illicit drugs, refers here to use of a psychoactive substance to the extent that it produces some sort of physical, cognitive, behavioral, or social impairment.

Although most of these acts may not seem very serious, they all can lead to very dangerous, even deadly, consequences (e.g., alcohol with other drugs, especially other CNS depressants).

Rates of absorption via other routes of administration are somewhere between those of inhalation and oral administration, depending somewhat on the availability of capillaries at the site of administration.

Users of psychoactive drugs choose their favorite drug partially because of how quickly the drug exerts its psychoactive effects.This sample Drug Addiction Research Paper is published for educational and informational purposes only. Drug Administration, Absorption, Metabolism, and Excretion IV. The goal of drug absorption is for the drug to circulate in the blood, and more specifically for a psychoactive drug, the goal is for it to circulate in the brain. Psychoactive drugs administered directly into the brain will have the most rapid effects because they will reach their CNS sites of action most quickly.If you need help writing your assignment, please use our research paper writing service and buy a paper on any topic at affordable price. Administration for the purpose of absorption in blood and brain can take various forms depending on type of substance (lipid soluble vs. Drugs administered through all other routes must be lipid-soluble in order to get through the formidable solid lipid barrier of the brain known as the blood brain barrier (BBB).The structure and arrangement of neurons allows for the transmission, integration, storage, and interpretation of information received via sensory receptors, as well as the control of bodily organs and muscles.In other words, these specialized cells (neurons) are responsible for everything we think, feel, and do. For example, taking more or fewer pills per dose or day, not using the drug the full time course as prescribed (e.g., antibiotics), using the drug past the expiration date, using the drug with other drugs (e.g., alcohol with barbiturates), or sharing prescriptions with others without a doctor’s permission are all forms of drug misuse. Misuse generally refers to the deviation from instructions on the label of over-the-counter drugs or the doctor’s instructions for prescription drugs. Although people use many psychoactive drugs for acceptable medicinal reasons, this research paper focuses on those psychoactive drugs that people use primarily for recreational, nonmedicinal reasons (e.g., to feel good, be more alert, alter or avoid reality). Psychologists are very interested in psychoactive drugs that change central nervous system (CNS; brain and spinal cord) activity, and thereby affect perception, thought, emotion, and behavior.Enzymes in the liver metabolize most of the psychoactive drugs described in this research paper into less lipid-soluble chemical products (metabolites).Some metabolites have their own effects on the body and brain.
