(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).
Opium is the milky exudate of the incised, unripe seedpod of the
opium poppy.
Opium poppy (Papaver somniferum) is the source for many natural and
semisynthetic narcotics.
Poppy straw concentrate is the alkaloid derived from the mature dried
opium poppy.
Qat (kat, khat) is a stimulant from the buds or leaves of Catha edulis
that is chewed or drunk as tea.
Stimulants are drugs that relieve mild depression, increase energy and activity, and include cocaine (coke, snow, crack), amphetamines (Desoxyn, Dexedrine), phenmetrazine (Preludin), methylphenidate (Ritalin), and others (Cylert, Sanorex, Tenuate).
Infant mortality rate: The number of deaths to infants under one year of age in a given year per l,000 live births occurring in the same year.
Land use: Human use of the land surface is categorized as arable land—land cultivated for crops that are replanted after each harvest (wheat, maize, rice); permanent crops—land cultivated for crops that are not replanted after each harvest (citrus, coffee, rubber); meadows and pastures—land permanently used for herbaceous forage crops; forest and woodland—land under dense or open stands of trees; and other—any land type not specifically mentioned above (urban areas, roads, desert). The percentage figure for irrigated refers to the portion of the entire amount of land area that is artificially supplied with water.
Leaders: The chief of state is the titular leader of the country who represents the state at official and ceremonial funcions but is not involved with the day-to-day activities of the government. The head of government is the administrative leader who manages the day-to-day activities of the government. In the UK, the monarch is the chief of state and the prime minister is the head of government. In the US, the President is both the chief of state and the head of government.
Life expectancy at birth: The average number of years to be lived by a group of people all born in the same year, if mortality at each age remains constant in the future.
Maritime claims: The proximity of neighboring states may prevent some national claims from being fully extended.
Merchant marine: All ships engaged in the carriage of goods. All commercial vessels (as opposed to all nonmilitary ships), which excludes tugs, fishing vessels, offshore oil rigs, etc. Also, a grouping of merchant ships by nationality or register.
Captive register—A register of ships maintained by a territory, possession, or colony primarily or exclusively for the use of ships owned in the parent country. Also referred to as an offshore register, the offshore equivalent of an internal register. Ships on a captive register will fly the same flag as the parent country, or a local variant of it, but will be subject to the maritime laws and taxation rules of the offshore territory. Although the nature of a captive register makes it especially desirable for ships owned in the parent country, just as in the internal register, the ships may also be owned abroad. The captive register then acts as a flag of convenience register, except that it is not the register of an independent state.
Flag of convenience register—A national register offering registration to a merchant ship not owned in the flag state. The major flags of convenience (FOC) attract ships to their register by virtue of low fees, low or nonexistent taxation of profits, and liberal manning requirements. True FOC registers are characterized by having relatively few of the ships registered actually owned in the flag state. Thus, while virtually any flag can be used for ships under a given set of circumstances, an FOC register is one where the majority of the merchant fleet is owned abroad. It is also referred to as an open register.
Flag state—The nation in which a ship is registered and which holds legal jurisdiction over operation of the ship, whether at home or abroad. Differences in flag state maritime legislation determine how a ship is manned and taxed and whether a foreign-owned ship may be placed on the register.
Internal register—A register of ships maintained as a subset of a national register. Ships on the internal register fly the national flag and have that nationality but are subject to a separate set of maritime rules from those on the main national register. These differences usually include lower taxation of profits, manning by foreign nationals, and, usually, ownership outside the flag state (when it functions as an FOC register). The Norwegian International Ship Register and Danish International Ship Register are the most notable examples of an internal register. Both have been instrumental in stemming flight from the national flag to flags of convenience and in attracting foreign-owned ships to the Norwegian and Danish flags.
Merchant ship—A vessel that carries goods against payment of freight. Commonly used to denote any nonmilitary ship but accurately restricted to commercial vessels only.
Register—The record of a ship's ownership and nationality as listed with the maritime authorities of a country. Also, the compendium of such individual ships' registrations. Registration of a ship provides it with a nationality and makes it subject to the laws of the country in which registered (the flag state) regardless of the nationality of the ship's ultimate owner.
Money figures: All are expressed in contemporaneous US dollars unless otherwise indicated.
Net migration rate: The balance between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (-9.26 migrants/1,000 population).
Population: Figures are estimates from the Bureau of the Census based on statistics from population censuses, vital registration systems, or sample surveys pertaining to the recent past, and on assumptions about future trends.
Total fertility rate: The average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to a given fertility rate at each age.
Years: All year references are for the calendar year (CY) unless indicated as fiscal year (FY).
