Notes, Definitions, and Abbreviations (continued)
GNP/GDP methodology: GNP/GDP dollar estimates for the OECD countries, the USSR, Eastern Europe, and a portion of the developing countries, are derived from purchasing power parity (PPP) calculations rather than from conversions at official currency exchange rates. The PPP methods involve the use of average price weights, which lie between the weights of the domestic and foreign price systems; using these weights US $100 converted into German marks by a PPP method will buy an equal amount of goods and services in both the US and Germany. One caution: the proportion of, say, military expenditures as a percent of GNP/GDP in local currency accounts may differ substantially from the proportion when GNP/GDP is expressed in PPP dollar terms, as, for example, when an observer estimates the dollar level of Soviet or Japanese military expenditures. Similarly, dollar figures for exports and imports reflect the price patterns of international markets rather than PPP price patterns.
Growth rate (population): The annual percent change in the population, resulting from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative.
Illicit drugs: There are five categories of illicit drugs narcotics, stimulants, depressants (sedatives), hallucinogens, and cannabis. These categories include many drugs legally produced and prescribed by doctors as well as those illegally produced and sold outside medical channels.
Cannabis (Cannabis sativa) is the common hemp plant, provides hallucinogens with some sedative properties, and includes marijuana (pot, Acapulco gold, grass, reefer), tetrahydrocannabinol (THC, Marinol), hashish (hash), and hashish oil (hash oil).
Coca (Erythroxylon coca) is a bush and the leaves contain the stimulant cocaine. Coca is not to be confused with cocoa which comes from cacao seeds and is used in making chocolate, cocoa, and cocoa butter.
Cocaine is a stimulant derived from the leaves of the coca bush.
Depressants (sedatives) are drugs that reduce tension and anxiety and include chloral hydrate, barbiturates (Amytal, Nembutal, Seconal, phenobarbital), benzodiazepines (Librium, Valium), methaqualone (Quaalude), glutethimide (Doriden), and others (Equanil, Placidyl, Valmid).
Drugs are any chemical substances that effect a physical, mental, emotional, or behavioral change in an individual.
Drug abuse is the use of any licit or illicit chemical substance that results in physical, mental, emotional, or behavioral impairment in an individual.
Hallucinogens are drugs that affect sensation, thinking, self-awareness, and emotion. Hallucinogens include LSD (acid, microdot), mescaline and peyote (mexc, buttons, cactus), amphetamine variants (PMA, STP, DOB), phencyclidine (PCP, angel dust, hog), phencyclidine analogues (PCE, PCPy, TCP), and others (psilocybin, psilocyn).
Hashish is the resinous exudate of the cannabis or hemp plant (Cannabis sativa).
Heroin is a semisynthetic derivative of morphine.
Marijuana is the dried leaves of the cannabis or hemp plant (Cannabis sativa).
Narcotics are drugs that relieve pain, often induce sleep, and refer to opium, opium derivatives, and synthetic substitutes. Natural narcotics include opium (paregoric, parepectolin), morphine (MS-Contin, Roxanol), codeine (Tylenol w/codeine, Empirin w/codeine, Robitussan A-C), and thebaine. Semisynthetic narcotics include heroin (horse, smack) and hydromorphone (Dilaudid). Synthetic narcotics include meperidine or Pethidine (Demerol, Mepergan), methadone (Dolophine, Methadose), and others (Darvon, Lomotil).
