Harvesting opium

To harvest opium, the skin of the ripening pods is scored by a sharp blade. The slashes exude a white, milky latex, which dries to a sticky brown resin that is scraped off the pods as raw opium.

Opium has powerful narcotic properties. Its constituents and derivatives are used as painkillers in extreme circumstances, such as in terminal stages of cancer. Therefore, a small amount of legal production is discretely conducted under strict supervision by law enforcement. The leading legal producers of opium are France and Australia. The French company Francopia produces 20% to 25% of the world's total, with total sales of approximately 60 million € (1 Euro (EUR) = 1.2085 Dollar (USD)).

Opium preparation

Raw opium must be processed and refined (called "cooking") before it is suitable for smoking. The raw opium is first dissolved in water and simmered over a low heat. The brown solution is then filtered to remove the insoluble vegetable waxes and then evaporated over a low heat. The result is a smokable form of opium with a considerably higher morphine content percentage-wise than the raw latex. This is then pressed into bricks and either transported to heroin laboratories or used as is.

Although opium is used in the form of paregoric to treat diarrhea, most opium imported into the United States is broken down into its alkaloid constituents. These alkaloids are divided into two distinct chemical classes, phenanthrenes and isoquinolines. The principal phenanthrenes are morphine, codeine, and thebaine, while the isoquinolines have no significant central nervous system effects and are not regulated under the Controlled Substances Act. Opium is also processed into heroin, and most current drug use occurs with processed derivatives rather than with raw opium.

Seed Capsules

The seed capsules also contain morphine, codeine, and other alkaloids. These pods can be boiled in water to produce a bitter tea that induces a long-lasting intoxication. Addiction to poppy tea is rare, but does occur.

Chemical properties and physiological effects

Opium resin contains two groups of alkaloids: phenanthrenes (including morphine and codeine) and benzylisoquinolines (including papaverine). Morphine is by far the most prevalent and important alkaloid in opium, consisting of 10%-16% of the total. It binds to and activates μ-opioid receptors in the brain, spinal cord, stomach and intestine. Regular use, even for a few days, invariably leads to physical tolerance and dependence. Various degrees of psychological addiction can occur, though this is relatively rare when opioids are used for treatment of pain, rather than for euphoric effects. These mechanisms result from changes in nervous system receptors in response to the drug. In response to the drug, the brain creates new receptors for opiates. These receptors are "pseudo" receptors and do not work. When the opiates are out of the body, the brain has more receptors than before the use of the drug, but only the same amount of endogenous opiate (endorphins) to fill these receptors.

MODERNIZATION AND REVOLUTION IN CHINA: From the Opium Wars to World Power, Third Edition
From Pacific Affairs, 4/1/05 by Askew, Joseph Benjamin

MODERNIZATION AND REVOLUTION IN CHINA: From the Opium Wars to World Power, Third Edition. By June Grosso,Jay Corrin and Michael Kart. Armonk (New York): M.E. Sharpe. 2004. xii, 353pp. US$79.95, doth, ISBN0-7656-1446-4; US$29.95, paper, ISBN 0-7656-1447-2.

In this book June Grasso, Jay Corrin and Michael Kort, three scholars with varied interests, have produced an interesting introduction to modern Chinese history. For the new third edition, Grasso, Corrin and Kort have added chapters dealing with Jiang Zemin and the "fourth generation" of leaders. As an introductory text this book covers the material and is a convenient size for students. Like many introductory texts it does not use any particularly new evidence nor does it produce any especially new interpretations. In many ways this is a disappointment. Jay Corrin has written excellent books on twentiethcentury Catholic intellectuals in Britain, but this text does not contain, as a reader might hope, a comparison of the struggles Chinese and Catholic intellectuals have had with democracy and modernity. Michael Kort has written extensively on the Soviet Union, yet this book does not compare the Soviet experience with that of the People's Republic.

As an introductory text this book's failings are mostly mainstream ones. A typical statement (pp. 28-29) is: "All foreigners had to adhere to strict regulations imposed by the cohong. They also had to live in designated areas called 'factories' outside Guangzhou itself, lest these foul-smelling barbarians-whom the Chinese called 'big noses,' 'hairy ones,' and similar epithets-contaminate the civilized Chinese."

No evidence is provided to prove that the Manchus feared contamination or even that they thought foreigners smelt bad. An echo of past prejudice is allowed to displace any discussion of the potentially rational reasons the Qing might have had for imposing the Canton system.

This book is also marred by errors of fact. Tibet does not, for example, share a border with any country of the former Soviet Union, much less with Russia (p. 301). Perhaps the most outstanding example of this sloppiness is the claim (p. 75) that the 1911 Revolution began in Wuchang, a city in Sichuan. An introductory text ought to be able to identify correctly the province in which a major event like the Xinhai Revolution began. The authors describe (p. 128) the "so-called 'three-thirds' system of government in CCP-controlled regions. Rather than establishing a CCP political monopoly, positions in local government were apportioned by thirds: one each for the CCP, for the [Guomindang], and for independents." The Guomindang did not, of course, hold any positions in the base areas. The authors imply an incorrect date for the purge of Gao Gang. The discussion of Tibet (pp. 301-302) misses important events and is generally very weak.

There are also problems of interpretation that do not reflect recent studies of the Communists. Chiang Kai-shek is roundly and thoroughly condemned. The book describes the Guomindang severing ties with the masses, of "harsh" repression and the like (pp. 100-102). This would not matter if the book took an even-handed approach to the Communists. There is no suggestion that a pro-Party writer was at more risk in CCP-controlled areas than in GMD-controlled ones. A simple count of the number of writers killed or imprisoned by both parties would have made the point neatly. The Communists are routinely given the benefit of the doubt; the Nationalists are not. The chapters on the post-Deng era rely heavily on the British Guardian and the New York Times. The more interesting commentary and analysis in the right-wing and neo-conservative Western press is ignored.

In a sense this book is overshadowed by what it could have been. It is not an ideal introduction to modern Chinese history. In spite of its deficiencies, if used with caution, it could provide an acceptable and compact introductory text.
