"I can remember the night that I suddenly realized what it was like to be crazy, or nights when my feelings and perceptions were of a religious nature. I had a very accurate sense that these feelings and perceptions, written down casually, would not stand the usual critical scrutiny that is my stock in trade as a scientist. If I find in the morning a message from myself the night before informing me that there is a world around us which we barely sense, or that we can become one with the universe, or even that certain politicians are desperately frightened men, I may tend to disbelieve; but when I'm high I know about this disbelief. And so I have a tape in which I exhort myself to take such remarks seriously. I say "Listen closely, you sonofabitch of the morning! This stuff is real!" I try to show that my mind is working clearly; I recall the name of a high school acquaintance I have not thought of in thirty years; I describe the color, typography, and format of a book in another room and these memories do pass critical scrutiny in the morning. I am convinced that there are genuine and valid levels of perception available with cannabis (and probably with other drugs) which are, through the defects of our society and our educational system, unavailable to us without such drugs. Such a remark applies not only to self-awareness and to intellectual pursuits, but also to perceptions of real people, a vastly enhanced sensitivity to facial expression, intonations, and choice of words which sometimes yields a rapport so close it's as if two people are reading each other's minds."

"This spectacular species is the most famous of all pitcher plants. Known to catch rats, frogs and lizards as well as insects, the huge pitchers of N. rajah are unmistakable. This species was named in honour of Sir James Brooke, one of the White Rajahs of Sarawak's past. It grows only on Mount Kinabalu and Mount Tambuyukon in Sabah, though it is not rare in this area. Legend has it that this species grows only in the spray zones around waterfalls, on ultramafic soils. Although it is true that it grows on ultramafic soils, it is certainly not found in the spray zones of waterfalls, but grows in open, grassy areas within its altitudinal distribution. Generally these areas are land slips or flat ridge tops, where the soil is loose. Although rainfall may be very high in these places, excess water seems to drain away quickly, and the plants are most common at seepages which are less prone to drying out. The stems of N. rajah tend to be decumbent rather than climbing. The leaves are distinctive, as the tendril is inserted about 2 cm from the apex. Although this characteristic is more pronounced in N. rajah and N. clipeata than in other species, it is not necessarily exclusive, as mature plants of many species have slightly peltate leaves. The lower pitchers are tub-shaped and do not sit upright, but lean back against other objects. Up to one litre of fluid may be contained in a pitcher. The peristome is wide and distinctly scalloped. The lid is vaulted and very large relative to the rest of the pitcher. The exterior parts of the pitcher are scarlet to purple, while the inside is yellow to purple. All other parts are yellow-green. Upper and intermediate pitchers are rarely produced, but are smaller, less brightly coloured, and more funnel-shaped than the lower pitchers. The flowers are usually brownish-yellow in colour and, like those of many Nepenthes, have a strong sugary smell. This species seems to flower at any time of the year and hybrids between it and all other Nepenthes species on Mount Kinabalu, except N. lowii, have been recorded. There is no noticeable variation within N. rajah, and no forms or varieties have been described."

"The most famous of all pitcher plants is the giant N. rajah, found only on Mount Kinabalu and neighbouring Mount Tambuyukon in Sabah. The pitchers are unmistakable in appearance, being large (≤35 cm high) and ovoid in shape with a huge, vaulted lid. The peristome is expanded and scalloped at the outer edge, while the inner margin is lined with short, sharp teeth. The pitchers rest on the ground and are often reclined, leaning against surrounding objects for support. The tendril joins the leaf blade just below the tip, which is a distinctive feature. The pitchers are usually dark purple in colour while the peristome ranges from red to purple. Nepenthes rajah grows in open, grassy vegetation in sites which are permanently moist. It always grows terrestrially in serpentine soils. There are no habitats of this type along the main summit trail of Mount Kinabalu, so it is not seen by most visitors. However, a small population persists near the newly opened Mesilau Resort, and interested visitors are sometimes taken to see these plants by the staff of Kinabalu Park. Some populations of N. rajah were seriously depleted by over collection in the 1970's. However, most populations are now off-limits to visitors and lie in remote parts of Kinabalu Park. Artificial propagation of plants in Western countries has helped reduce demand for plants collected from the wild, so the long term outlook for the survival of N. rajah in the wild is comparatively good."

"In addition to such wholly separable types of causation, science has still to deal with the interaction of vitalistic and mechanistic causes. It is in the discussion of influences interacting between complex and simple energy units that the greatest confusions and conflicts of scientific analysis arise. For instance, let us suppose that science is called upon to describe the plant growing in a field. It can be shown definitely that the soil is delivering a continuous series of chemical stimuli to the plant. It is equally ascertainable that the plant reacts to these stimuli with a series of reactions peculiar to its own inherent nature. Some of these plant responses will result in the delivery of counter stimuli to the soil and some will not. Those influences which are exercises by the plant over the soil will, for the most part, alter the soil in ways determined by the chemical power of the plant. In so far, therefore, as soil and plant interchange influences, it may fairly be said that the more complex units of energy composing the plant will dominate the interplay of causal forces. But, as we have noted, there will be many changes in the plant, as a result of reactions to soil stimuli, which will not direct any influence back toward the earth. Where these plant changes directed by the soil to its own ultimate benefit, then we might clearly assume that the simpler form of energy was in causal control of the more complex energy unit. That is to say if the soil were able to use the more complex energy of the plant to effect its own enlargement, simply by stimulating the plant to act according to the plant’s own principles of action, we might conclude that, after all, the balance of control lay with the simpler unit of energy. This would amount to the philosophical admission that mechanistic causation holds the balance of power. But such does not appear to be the case. Though stimulated to action by the soil, the plant reacts with its own energy according to its own innate principles of action, and with reaction tendencies designed for its own ultimate benefit. With innate power to develop spontaneously throughout its own life cycle, with a balance of power of interaction capable of changing the soil more radically than the soil can change it, and, finally, with a structure designed in such a way as always to react for its own benefit when stimulated to action by the soil, we are forced to conclude that the plant is a more potent generator of effective causes than the soil."

"As the most powerful state, the U.S. makes its own laws, using force and conducting economic warfare at will. It also threatens sanctions against countries that do not abide by its conveniently flexible notions of "free trade." In one important case, Washington has employed such threats with great effectiveness (and GATT approval) to force open Asian markets for U.S. tobacco exports and advertising, aimed primarily at the growing markets of women and children. The U.S. Agriculture Department has provided grants to tobacco firms to promote smoking overseas. Asian countries have attempted to conduct educational anti-smoking campaigns, but they are overwhelmed by the miracles of the market, reinforced by U.S. state power through the sanctions threat. Philip Morris, with an advertising and promotion budget of close to $9 billion in 1992, became China's largest advertiser. The effect of Reaganite sanction threats was to increase advertising and promotion of cigarette smoking (particularly U.S. brands) quite sharply in Japan, Taiwan, and South Korea, along with the use of these lethal substances. In South Korea, for example, the rate of growth in smoking more than tripled when markets for U.S. lethal drugs were opened in 1988. The Bush Administration extended the threats to Thailand, at exactly the same time that the "war on drugs" was declared; the media were kind enough to overlook the coincidence, even suppressing the outraged denunciations by the very conservative Surgeon-General. Oxford University epidemiologist Richard Peto estimates that among Chinese children under 20 today, 50 million will die of cigarette-related diseases, an achievement that ranks high even by 20th century standards."

"Indeed, without tobacco it is doubtful whether the Virginia colony could have survived at all. Initially all the authorities, at home and abroad, were against tobacco farming, largely because King James I hated the “weed,” thinking it “tending to general and new Corruption both of Men’s Bodies and Manners.” Governor Dale actually legislated against it in 1616, ordering that only one acre could be laid down to tobacco for every two of corn. It proved impossible to enforce. By the next year tobacco was being laid down even in Jamestown itself, in the streets and market-place. Men reckoned that, for the same amount of labor, tobacco yielded six times as much as any other crop. It was grown close to the banks of many little rivers, such as the James, the York, and the Rappahannock. Every small plantation had its own riverside wharf and boat to get the crop to a transatlantic packet. Roads were not necessary. Land would yield tobacco only for three years: then a fresh set of fields had to be planted. But the real problem was labor—hence slavery. The increasing supply of cheap, high-quality slave-labor from Africa came (as the planters would say and believe) as a Godsend to America’s infant tobacco industry. So it flourished mightily. James I himself signaled his capitulation as early as 1619 when he laid a tax of a shilling in the pound (5 percent) on tobacco imports to England, though he limited the total (from Bermuda as well as Virginia) to 55,000 lb a year. But soon all such quantitative restrictions were lifted and tobacco became the first great economic fact of life in the new English-speaking civilization growing up across the Atlantic. It continued to be counted as a blessing over four centuries until, in the fullness of time, President Bill Clinton brought the wheel back full circle to the days of James I, and in August 1996 declared tobacco an addictive drug."

"Persistent infection, wherein a pathogen is continually present in a host individual, is widespread in virus–host systems. However, little is known regarding how seasonal environments alter virus–host interaction during such metastability. We observed a lineage-to-lineage infection of the host plant Arabidopsis halleri with Turnip mosaic virus for 3 years without severe damage. Virus dynamics and virus–host interactions within hosts were highly season dependent. Virus accumulation in the newly formed leaves was temperature dependent and was suppressed during winter. Transcriptome analyses suggested that distinct defence mechanisms, i.e. salicylic acid (SA)-dependent resistance and RNA silencing, were predominant during spring and autumn, respectively. Transcriptomic difference between infected and uninfected plants other than defence genes appeared transiently only during autumn in upper leaves. However, the virus preserved in the lower leaves is transferred to the clonal offspring of the host plants during spring. In the linage-to-linage infection of the A. halleri–TuMV system, both host clonal reproduction and virus transmission into new clonal rosettes are secured during the winter–spring transition. How virus and host overwinter turned out to be critical for understanding a long-term virus–host interaction within hosts under temperate climates, and more generally, understanding seasonality provides new insight into ecology of plant viruses."
