Call 1–800-BITE-ME." Billboards with that piquant message on behalf of Kick were posted in three Ohio communities. A spokesman for the company explained that its intent had been to be tasteless and tacky to attract the soda’s targets market of high school and college men. The telephone number, by the way, isn’t real: It lacks the requisite eleventh digit.

  caffeine culture and le fin de millénaire

  1. Laboratory studies to date, in which subjects are challenged with larger single doses, shed little light on the ways in which most people actually use caffeine, that is, ingesting it in small amounts throughout the day and taking relatively little after dinner.

  4. In terms of dollars, coffee, cacao, and tea are each important agricultural products. In terms of dollar value, coffee is the largest agricultural commodity in the world, and it is second only to oil among all commodities. In 1985 the world value of trade in coffee every year was more than $15 trillion, that of cacao exceeded $7 trillion, and that of tea topped $2.5 trillion, with a total world value of these three caffeine crops of near $25 trillion annually.

  2. Before Boyle, the Greek philosopher Empedocles had taught that four underived and indestructible substances, fire, water, earth, and air, were the constituents from which all other things are compounded, and this theory had reigned unchallenged since ancient times.

  5. Jack E.James, Caffeine and Health, p. 81. On caffeine’s slowing of the metabolization of alcohol, James cites J.George et al., “Influence of Alcohol on Caffeine Consumption and Caffeine Elimination,” Clinical and Experimental Pharmacology and Physiology 13 (1986): 731–36; M.C.Mitchell et al., “Inhibition of Caffeine Elimination by Short Term Ethanol Administration,” Journal of Laboratory and Clinical Medicine 101 (1983): 826–34. James also notes that Nash's speculative antagonistic effect between caffeine and alcohol may occur, but if it does, is probably clinically insignificant, citing R.Fudin and R.Nicastro, “Can Caffeine Antagonize Alcohol-Induced Performance Decrements in Humans?” Perceptual and Motor Skills 67 (1988): 375–91.

  6. Richard Gilbert, Caffeine: The Most Popular Stimulant, p. 62. Gilbert states, “Some of the variability in the rates of caffeine metabolism is inherited. Asians, for example, appear to metabolism caffeine differently and more slowly than Caucasians. Some of the variability, however, may be the result of experience with caffeine. Regular caffeine users may metabolize caffeine more quickly, though this has not yet been proven.”

  7. Jack James, Caffeine and Health, p. 81. Caffeine’s ability to antagonize alcohol-induced drowsiness is the one antagonism which he finds the most credible.

  8. Jacob, Epic of a Commodity, p. 22.

  9. Another related theory, of questionable probative value, is that caffeine achieves its effects by benzodiazepine receptors that regulate the activity of GABA (gamma-amino butyric acid), an amino acid highly concentrated in the central nervous system that has a very powerful depressant effect on neuronal discharge. An antagonistic effect on these receptors, by inhibiting the action of GABA, could account for caffeine’s stimulant effect. However, although the antagonism between caffeine and benzodiazepines in vitro and in vivo is clearly established, the concentrations of caffeine reached after coffee consumption leave doubts about the significance of this effect in dietary doses of caffeine.

  13. For the median values for tea prepared from tea bags of black tea, averages among all brands, see the 1979 study by Bunker and McWilliams, published in the Journal of the American Dietetic Association. The same study found that the amount of caffeine in tea increases with brewing time and that the finer the particles of tea leaves, the more caffeine is extracted into the cup. The mean caffeine contents for all brews of regular black bag tea per cup were 28 mg for one-minute brews, 44 mg for three-minute brews, and 47 mg for five-minute brews. Black tea contained more caffeine than green teas.

  8. Ibid. De Clieu’s heroic husbandry has been glorified in prose and poetry by his admiring countrymen. Joseph Alphonse Esménard (1769–1811), a Creole poet of indifferent gifts who delighted in maritime themes, describes his devotion through the dreadful calm, writing that the officer, though parched by the broiling sun,

  Yet does not slake his own consuming thirst,

  But drop by drop revives the sapling first,

  His suffering eased by what his visions show,

  Who from this shoot sees great plantations grow.

For example, when boiling water is poured over the curling leaves in a pot, and they release their caffeine and tannin, this is luridly called the “agony of the leaves” by those in the tea business.

  29. Phillips reports an unusual use for the wood: “It is from the wood of this tree that our most esteemed German flutes have for some years past been made, as they are not so subject to swell by using as those made from Box-wood; which swelling often causes a variation of half a note, as after being played on for short time the tone become sharper. The cacao flutes have also an objectionable quality, viz., as they are subject to crack by use, and will not stand the breath of different persons. A respectable professor of this instrument, among other instances, informed us of a gentleman who after having played on a cacao flute for seven years without accident, sold it to a friend, by whose breath alone three joints were split, in the course of a few months practice.” (Phillips, Orchard, p. 71)

  19. Ibid., p. 163. Studies in the 1980s by David Robertson profiled the tolerance to caffeine’s hemodynamic and neurohumoral (of or pertaining to a chemical transmitted by a neuron, such as acetylcholine, serotonin, dopomine, or epinephrine) effects among people with normal and high blood pressure. He concluded that, while his study confirmed the moderate pressor effect of caffeine, it “demonstrated rapid and essentially complete tolerance to the hemodynamic and neurohumoral effects over as short a period as three to four days.”
