Tobacco is the name given to the leaves of those varieties of the Nicotiana which are prepared in different forms for use as a narcotic. It is generally manufactured for smoking, but also for chewing and as snuth.
The word tobacco is probably derived from tobaco, the name given to a peculiar Y-shaped instrument used by the old inhabitants of the island of Santo Domingo for inhaling tobacco-smoke through the nostrils. Other authorities claim that the name of the herb is derived from the Mexican word tabacco. Columbus and his party made the earliest European reference to tobacco on their return from the voyage to Cuba in 1492. The tobacco plant was first brought to Europe in 1558 by Francisco Fernandes, a Spanish physician. The wonderful healing properties which the plant was supposed to possess caused the habit of smoking and snuff-taking to spread with great rapidity over almost the whole of Europe. Jean Nicot, French ambassador to Portugal, who gives his name to the genusNicotiana, sent a present of tobacco seeds to Catherine de'Medici, and she initiated in France the snuff-taking habit as a cure for headache. This habit soon spread to Scotland and Ireland, where it remained popular long after the smoking habit had become established in England.
The smoking of tobacco was really started by English example. In 1586, Ralph Lane, the first governor of Virginia, and Sir Francis Drake brought smoking materials and implements to Sir Walter Raleigh, who very rapidly popularised the custom.
Most of the tobacco used in the 17th and 18th centuries was grown in Virginia by English colonists, whose industry was carefully protected by laws prohibiting the production of tobacco in the British Isles.
There are about 50 species of Nicotiana, most of them indigenous to America. Of these, three varieties are in general use by smokers: (1) Nicotiana tabacum, the Virginian variety, originally derived from the South or Central American seed, and now cultivated in almost all temperate and warmer climates. (2) Nicotianarustica, grown principally in Turkey, Syria, and India. This is milder in flavour, and is principally used for the manufacture of cigarettes. It burns too quickly for a pipe tobacco. (3) Nicotiana Persica, or Persian tobacco, which is good for pipe tobacco, but not sufficiently uniform for the manufacture of cigars.
The tobacco plant is a coarse, rank-growing annual. Its stem is simple and unbranched, and grows to a height of about two meters, terminating in a bunch of yellow or rose-coloured flowers. The East Indian variety is slightly different, producing a green tobacco from a smaller plant. It is derived from the Mexican seed, and is also cultivated in Southern Germany and Hungary.
The tobacco plant can be cultivated in every part of the world, but with widely varying measures of success. It is grown in British gardens for the sake of its flowers. Clayey, moist soils produce tobaccos which are dark brown or reddish in colour when cured. Bright and yellow tobaccos are grown on sandy soils, and the leaf of this variety is thinner. The bright tobacco produced in Virginia and North Carolina is all grown in loose sandy soil with a clay subsoil.
The tobacco seeds are generally sown in nursery beds, and set out later. About 3OOOOO to 4000000 go to the ounce, and this produces about 40,000 plants, for which 50 square yards of nursery bed are sufficient. The seeds are sown at the end of March or beginning of April, in rich, heavy soil which has been carefully prepared and fertilised. The seedlings remain in the nursery from fifty to sixty days, during which time the fields are well tilled and manured. Transplanting is done on a warm, rainy day, and the young plants set in ridges varying from one to four feet in width. Ridges of one to one and a half feet are most usual in Cuba and Sumatra, as the wider ridge produces a leaf which is too coarse for the purpose of cigar-making.
The crop takes another two months until it flowers, and at this stage the buds are pinched off or 'topped', and some of the leaves pruned, so that only a certain number are left to ripen. For cigar-tobacco, from 15 to 20 leaves are left on the plant; for the best smoking tobaccos, 10 to 12 leaves. Plants which have been topped form suckers, and in Florida these are left to produce a second, although inferior, sucker crop.
The leaves take about 35 days to ripen after the plants are topped and pruned. The ripening leaf changes from a dark to a lighter yellowish-green colour, and is often mottled and becomes gummy. The ripe leaf cracks and creases when folded. The lower leaves ripen first, and for the best tobaccos the leaves are picked singly ;
as they ripen. For the bulk of the tobaccos, however, the whole plant is cut when the middle leaves are ripe. Warm, cloudy days are best for cutting, and the plants are not gathered in hot sunshine or when they are wet from rain or dew.
After harvesting the plants are left in the open to wilt, and are then conveyed to the drying-house or ventilating-barn, where they are straddled across tiers of poles and dried in a temperature which is raised to 170° F for four to five days. On damp days the moisture is allowed to penetrate into the drying-house to make the leaves pliable.
The plants are then taken down and stripped, and the leaves sorted into firsts, seconds, and lugs - the name given to the inferior leaves. They are formed into hands containing ten to twelve leaves, and these are left in heaps and fermented at a temperature of about 130° F for from three to four weeks. The heaps are shuffled from time to time, to allow all the leaves to assume a uniform brown tint. This process is called the fermenting or sweetening process. In the non-fermenting processes the leaves are simply sun-cured, or sun-dried, and this tobacco is used chiefly for chewing tobaccos. In the fermenting process the starch and sugar in the leaf are decomposed, but they are retained in the sun-dried process. Lastly, the leaves are packed carefully in hogsheads for shipment.
Tobacco leaf is used for making into various smoking mixtures, roll tobacco, cake or plug, cigars, cigarettes, and snuff. For snuff the leaf requires very careful fermentation during several weeks. It is ground up and flavoured so as to produce the greatest possible amount of free ammonia, free nicotine, and other aromatic scents. Syria produces and manufactures a smoking tobacco which is known as Latakia. It is similar to Turkish-grown tobacco, but differently treated. The plants are not topped. The seeds as well as the leaves are included in the curing, this taking place in the smoke of a fire of evergreen-oak, which gives a black colour and a peculiarly strong flavour to the tobacco.
Tobacco for pipe-smoking is mostly grown in the USA, the chief states being Kentucky, North Carolina, and Virginia. Louisiana grows a dark, almost black, and very strong tobacco known as perique. Cigarette tobaccos are principally imported from Virginia, and Turkish and Egyptian cigarettes are also in great demand. The Egyptian cigarette is made from Turkish leaf, as the cultivation of tobacco in Egypt was prohibited in 1891. The best cigar tobaccos are grown in Cuba. A very good cigar leaf is also produced in Jamaica, Sumatra and North Borneo.
Since the introduction of tobacco into England, it has been subject to continuous legislation and import duties. In the early days a certain quantity of tobacco was grown in England for domestic consumption, and quite a considerable trade was done with Turkey, which, at that time, imported her tobacco supplies from England. Queen Elizabeth imposed a tax of 2d per Ib on imported tobacco. In 1621 James I increased this to 6s. lOd. per Ib.
During the American War of Independence, England's source of supply and the revenue there from were temporarily suspended, and tobacco was again widely planted in England, although the prohibition laws had not been repealed. These laws had never applied to Scotland, and to reimburse themselves for the loss of revenue during the non-importation of American tobacco, the Government purchased the Scotch tobacco crops at the fixed price of 4d. per Ib., thus temporarily creating a Government monopoly in tobacco. The ban on the growing of tobacco in the British Isles, renewed in 1782 in England, and in 1830 in Ireland, was modified later in the 19th century, and tobacco can now be cultivated under licence.
During the late 20th century an American-led ban on tobacco smoking supposedly because of the connection with lung cancer, but more likely under pressure from the pharmaceutical lobby, in public places slowly extended to Britain, with Scotland banning the smoking of tobacco in pubs and clubs in 2005.

Opium is the dried, milky juice (latex) of unripe capsules of the white poppy also known as the opium poppy (Papaver somniferum), a plant probably indigenous in the south of Europe and western Asia, but now so widely cultivated that its original habitat is uncertain.
The medicinal properties of the juice have been recognized from a very early period. It was known to Theophrastus and appears in his time to have consisted of an extract of the whole plant, since Dioscorides about 77 AD draws a distinction between different types of opium, one of which he describes as an extract of the entireherb, and the more active form derived from the capsules alone. From the 1st to the 12th century the opium of Asia Minor appears to have been the only kind known in commerce. In the 13th century opium thebaicum is mentioned by Simon Januensis, physician to Pope Nicholas IV.
In the 16th century opium is mentioned by Pyres in 1516 as a production of the kingdom of Cous (Kuch Behar, south-west of Bhutan) in Bengal and of Malwa. Its introduction into India appears to have been connected with the spread of Islam. The opium monopoly was the property of the Great Mogul and was regularly sold. In the 17th century Kaempfer describes the various kinds of opium prepared in Persia, and states that the best sorts were flavoured with spices and called theriaka. These preparations were held in great esteem during the Middle Ages, and probably supplied to a large extent the place of the pure drug.
Opium is said to have been introduced into China, probably by the Arabs around 1280-1295, during the reign of Taitsu, and its use seems to have temporarily ceased in 1368. It appears to have been commonly used in that country as a medicine before the trade with India started. In a Chinese herbal compiled prior to the 17th century both the plant and its inspissated juice are described, together with the mode of collecting it, and in the General History of the Southern Provinces of Yunnan, revised and republished in 1736, opium is noticed as a common product up to this date, however, it was imported in comparatively small quantity by the Chinese solely as a remedy for dysentery, diarrhoea, and fevers, and was usually brought from India by junks as a return cargo.
In 1757 the monopoly of opium cultivation passed into the hands of the East India Company through the victory of Clive at Plassey. Up to 1773 the trade with China had been in the hands of the Portuguese, but the quantity annually exported to that country rarely exceeded 200 chests. In that year the East India Company took the trade under their own charge, and in 1776 the annual export reached 1000 chests, and 4054 chests in 1790. Although the importation was forbidden by the Chinese emperor Keaking in 1796, and opium-smoking punished with severe penalties, which were ultimately increased to transportation and death, the trade continued and had increased during 1820-1830 to 16,877 chests per annum. In 1839 a proclamation was issued threatening hostile measures if the English opium ships serving as depots were not sent away. The demand for removal not being complied with, 20,291 chests of opium (of 149.3 Ib each), valued at 2,000,000 pounds sterling, were destroyed by the Chinese commissioner Lin; but still the British sought to smuggle cargoes on shore, and some outrages committed on both sides led to an open war, which was ended by the treaty of Nanking in 1842. From that time until the end of the 19th century, in spite of the remonstrances of the Chinese Government, the exportation of opium from India to China continued, having increased from 52,925 piculs (of 133.3 Ib) in 1850 to 96,839 piculs in 1880. It appears to be certain, however, that, while the court of Peking was endeavouring to suppress the foreign trade in opium from 1796 to 1840, it did not or could not put a stop to the home cultivation of the drug, since a Chinese censor in 1830 represented to the throne that the poppy was grown over one-half of the province of Chekeang, and in 1836 another, Cho Tsun, stated that the annual produce of opium in Yunnan could not be less than several thousand piculs.
In 1885 it was estimated that south-western China, including Szechuen, produced not less than 224,000 piculs, while the entire import from India did not exceed 100,000 piculs. Opium was then produced in nine out of the eighteen provinces of China. The comparative cheapness of the Chinese opium, the lighter duties levied upon it, and the increasing care taken in its cultivation were enabling it to compete successfully with the Indian drug even in eastern China, where, however, it was hitherto chiefly used to mix with and cheapen the foreign article.
The amount of opium imported into Great Britain in 1861, 1871, and 1881 was 284,005, 591,466, and 793,146 lbs respectively, and the exports for the same years 290,120, 307,399, and 401,883 lb.
The method of cultivationa nd manufacture varies between countries, but generally the opium poppy is cultivated from seeds sown between November and March, and successive crops are ready from May to July. The flowers are white or purplish, there being different varieties of opium poppies; and a few days after the petals have fallen, when the capsules are about 25 mm. in diameter, they are cut round the middle with a knife, and left overnight for the juice to flow out and harden. After further drying on poppy leaves, the dark, plastic masses are made into lumps for sale.
Opium is bitter, and has a characteristic smell. Its properties depend upon the nineteen or twenty alkaloids it contains. The chief of these are: Morphine (9 per cent); narcotine (5 per cent); papaverine (0.8 per cent) ; thebaine (0.4 per cent); codeine or methylmorphine (0.3 per cent); narceine (0,2 per cent.). Morphine, the most important alkaloid, is separated from the others by extracting the opium with hot water, and boiling the extract with milk of lime. Alcoholic tincture of opium is known as laudanum. It contains about 0.75 per cent, of morphine.
Opium is used medicinally, mainly to relieve pain and to produce sleep, and for this purpose is best given hypodermically as morphine. It is also employed to relieve vomiting and to stop diarrhoea, to lessen distressing coughing, to stop bleeding in the stomach and intestines; while it is valuable in heart disease, diabetes, in cystitis and other inflammatory conditions, for haemoptysis, and, as Dover's powder, to cause perspiration in, for instance, common cold.
A conference of the Powers at the Hague in January 1912, drew up a convention of twenty-five articles by which they agreed to control the supply of and gradually suppress the manufacture of opium. Research Opium
