        Returning Spanish conquistadores introduced it to Europe. Coca was touted as "an elixir of life". In 1814, an editorial in Gentleman's Magazine urged researchers to begin experimentation so that coca could be used as "a substitute for food, so that people could live a month, now and then, without eating..."

        The active ingredient of the coca plant was first isolated in the West around 1860. Freud described cocaine as a magical drug. He wrote a song of praise in its honour. He also practised extensive self-experimentation. To Sherlock Holmes, cocaine was "so transcendentally stimulating and clarifying to the mind that its secondary action is a matter of small moment". Doctors dispensed cocaine as an antidote to morphine addiction. Unfortunately, some patients made a habit of combining both.

         Cocaine was soon sold over-the-counter. Until 1916, one could buy it at Harrods. It was widely used in tonics, toothache cures and patent medicines; and in chocolate cocaine tablets. Prospective buyers were advised - in the words of pharmaceutical firm Parke-Davis - that cocaine "could make the coward brave, the silent eloquent, and render the sufferer insensitive to pain".

        When combined with alcohol, the cocaine alkaloid yields a further potently reinforcing compound, now known to be cocaethylene. Thus cocaine was a popular ingredient in wines, notably Vin Mariani. Coca wine received endorsement from prime-ministers, royalty and even the Pope. Frédérick-Auguste Batholdi observed that if only he had used Vin Mariani earlier in his life, then he would have engineered the Statue of Liberty a few hundred meters higher.

        Coca-cola was introduced in 1886 as as "a valuable brain-tonic and cure for all nervous afflictions". It was promoted as a temperance drink "offering the virtues of coca without the vices of alcohol". The new beverage was invigorating and popular. Until 1903, a typical serving contained around 60mg of cocaine. Sold today, it still contains an extract of coca-leaves. Coca Cola imports eight tons from South America each year. Nowadays the leaves are used only for flavouring since the drug has been removed.

        A coca leaf typically contains contains between 0.1 and 0.9 percent cocaine. If chewed in such form, it rarely presents the user with any social or medical problems. When the leaves are soaked and mashed, however, cocaine is extracted as a coca-paste. The paste is 60 to 80 per cent pure. It is usually exported in the form of the salt, cocaine hydrochloride. This is the powdered cocaine most common, until recently, in the West. Drug testing for cocaine aims to detect the presence of its major metabolite, the inactive benzoylecgonine. Benzoylecgonine can be detected for up to five days in casual users. In chronic users, urinary detection is possible for as long as three weeks.

        Yet old-fashioned cocaine hydrochloride still wasn't good enough. Sensation-hungry thrill-seekers have long sought the ultimate high from the ultimate "rush". They haven't been satisfied with the enhanced mood, sexual interest, self-confidence, conversational prowess and intensified consciousness to be derived from just snorting cocaine. Normally, only the intravenous route of administration could be expected to deliver the more potent and rapid hit they have been seeking. Yet there are very strong cultural prejudices against injecting recreational drugs. So a smokeable form was developed.

        Since the hydrochloride salt decomposes at the temperature required to vaporise it, cocaine is instead converted to the liberated base form. Initially, "free-base" cocaine was typically produced using volatile solvents, usually ether. Unfortunately, this technique is physically dangerous. The solvent tends to ignite. Hence a more convenient method of producing smokeable free-base became popular. Its product is crack. To obtain crack-cocaine, ordinary cocaine hydrochloride is concentrated by heating the drug in a solution of baking soda until the water evaporates. This type of base-cocaine makes a cracking sound when heated; hence the name "crack". Base-cocaine vaporises at a low temperature, so it can be easily inhaled via a heated pipe.

        Crack-cocaine delivers an intensity of pleasure completely outside the normal range of human experience. It offers the most wonderful state of consciousness, and the most intense sense of being alive, the user will ever enjoy. (S)he will access heightened states of being whose modes are unknown to chemically-naïve contemporaries. Groping for adequate words, crack-takers sometimes speak of the rush in terms of a "whole-body orgasm". Drug-naive virgins - slightly shop-soiled or otherwise - cannot be confident (unless in thrall to ill-conceived logical behaviorist theories of meaning) that they have grasped the significance of such an expression. For to do so, it would be necessary to take the drug via its distinctive delivery-mechanism oneself. This is at best very imprudent.

         Ultimately, the emotional baseline, and affective analogue of Absolute Zero, characteristic of post-humanity in its hedonically enriched modes of awareness may be greater than anything we can now grasp. It may be higher than the rapturous transports of the most euphoric coke-binge in paleo-human history. In the meantime, a drug which induces a secular parody of Heaven commonly leads the user into a biological counterpart of Hell.

When Is It Best To Take Crack Cocaine?
As a rule of thumb, it is profoundly unwise to take crack-cocaine. The brain has evolved a truly vicious set of negative feedback mechanisms. Their functional effect is to stop us from being really happy for long. The initial short-lived euphoria of a reinforcer as powerful as crack will be followed by a "crash". This involves anxiety, depression, irritability, extreme fatigue and possibly paranoia. Physical health may deteriorate. An intense craving for more cocaine develops. In heavy users, stereotyped compulsive and repetitive patterns of behaviour may occur. So may tactile hallucinations of insects crawling underneath the skin ("formication"). Severe depressive conditions may follow; agitated delirium; and also a syndrome sometimes known as toxic paranoid psychosis.
        The social consequences of heavy cocaine use can be equally unpleasant. Non-recreational users are likely eventually to alienate family and friends. They tend to become isolated and suspicious. Most of their money and time is spent thinking about how to get more of the drug. The compulsion may become utterly obsessive. The illusion of free-will is likely to disappear. During a "mission", essentially a 3-4 day crack-binge, users may consume up to 50 rocks a day. Whereas "empathogens" such as ecstasy - which trigger the release of far more serotonin than dopamine - will typically promote empathy, trust, compassionate love and sociability, mainly dopaminergic drugs, if taken on their own and to excess, can easily have the reverse effect. Simplistically, cocaine tends to be a "selfish" drug.

        There is perhaps a single predictable time of life when taking crack-cocaine is sensible, harmless and both emotionally and intellectually satisfying. Indeed, for such an occasion it may be commended. Certain estimable English doctors were once in the habit of administering to terminally-ill cancer patients an elixir known as the "Brompton cocktail". This was a judiciously-blended mixture of cocaine, heroin and alcohol. The results were gratifying not just to the recipient. Relatives of the stricken patient were pleased, too, at the new-found look of spiritual peace and happiness suffusing the features of a loved one as (s)he prepared to meet his or her Maker.

        Drawing life to a close with a transcendentally orgasmic bang, and not a pathetic and god-forsaken whimper, can turn dying into the culmination of one's existence rather than its present messy and protracted anti-climax.

        There is another good reason to finish life on a high note. In a predominantly secular society, adopting a hedonistic death-style is much more responsible from an ethical utilitarian perspective. For it promises to spare friends and relations the miseries of vicarious suffering and distress they are liable to undergo at present as they witness one's decline.

        A few generations hence, the elimination of primitive evolutionary holdovers such as the ageing process and aversive experience will make the social institutionalisation of the hedonistic death advocated here redundant. In the meanwhile, one is conceived in pleasure and may reasonably hope to die in it.
