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.
An adult drinking alcohol to relax or smoking cigarettes to stop the jitters are examples of recreational use of licit (legal) drugs in this country, and smoking crack to feel euphoric or injecting heroin for the “rush” are examples of illicit (illegal) recreational drug use.For example, heroin is the preferred drug for some opiate addicts because it is more lipid soluble, is absorbed into the brain faster, and produces a faster, more intense “rush” than morphine does.Before drugs can stop working in the body, they must be either broken down into other substances (metabolized) or removed from the body (excreted). Nonetheless, society sends mixed messages about drug use, with commercials warning against the evils of illicit drug use and advertisements offering wonder treatments in a “purple pill.” Drugs in and of themselves are not “evil,” but every drug can be misused and abused. With pills to treat everything from the symptoms of the common cold to the positive symptoms of schizophrenia, drug use is prevalent in the United States, and pharmaceuticals are a multibillion-dollar industry.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). 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. 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.
