Coca and cocaine

Coca is not a drug, it’s food.

Coca, scientifically known as Erythroxylon Coca is a medicinal and ceremonial plant traditionally used by Andean cultures.
It is a medium height bush that grows in hot, humid climates on the lower slopes of mountains. Since ancient times coca leaves were, and still are, used due to its medicinal and ritual purposes. They are chewed, ingested or prepared in infusion.
Coca leaves are actually an essential dietary supplement in the social and ecological conditions of the Andes. They contain a considerable proportion of the requirements of vitamins and minerals. They also supress hunger, improving life in the jungle and mountain environments where the availability of protein may be limited by local or seasonal factors. Another property of coca, related to its alkaloid content is its stimulating effect, it also facilitates  efforts in conditions of the low oxygen content of the mountain heights.
Coca leaf tea or «mate de coca» is also consumed in Peru and Bolivia to relieve altitude sickness or «altitude sickness» and as a digestive. The medicinal properties of coca resemble to some extent the Mapuche “boldo”.
During colonial times, Spanish authorities used these stimulant and appetite suppressant properties of coca to improve workers performance in the difficult silver miners conditions.
Coca trade provided considerable income to the colonial authorities. In 1583 more than one millon kilos of coca leaves were brought to the mines of Upper Peru.

Coca alkaloids
Coca contains numerous alkaloids which give its known therapeutic properties. The best known alcaloid is cocaine that has stimulant and digestive effects. Other alkaloids contained in coca include atropine, egnomina, the pecticina, papain, hygrine, globulin, quinoline, conina, cocamine, reserpine, benzoin, inulin and pyridina.

Cocaine
Cocaine is structurally to Solanaceae alkaloids such as belladonna, henbane, mandragora and datura.
Its usual formula is cocaine hydrochloride, and apparently,it prevents the absorption of certain transmitters that have been released by other means.
Minimum active dose of nasal application is about 20-30 mg while the lethal dose is 1 to 1.5 grams. It has a high tolerance and some people have ingested 4-5 grams daily without lethal effects.
This alkaloid was first isolated in 1859 by Florentine researcher Paolo Mantegaza and Austrian Karl Cherence.
In those days it was considered as an almost miraculous substance.
It was at this time that Dr Frances Angelo Mariani visiting Potosí, Bolivia, observed the natives chewing coca and upon his return to France developed a product which he called Mariani Wine. This “wine” was sold with great success.
In the late nineteenth century, coca and cocaine became popular and prestigious European intellectuals and professional classes became regular consumers.
Sigmond Freud himself stated:
At present it is impossible to assess with certainty the extent to which coca can potentially increase human mental powers. I have the impression that prolonged use of cocaine can lead to a lasting improvement if the inhibitions expressed before it is consumed only to be physical causes or exhaustion. Of course, the instantaneous effect of a dose of cocaine can not be compared with an injection of morphine; But from the positive point of view, there is no danger of damage to the body generally as is the case with chronic use of morphine."
Then Freud himself would deny such early claims.
Enthusiasm generated by coca and cocaine in Western society led to their use in medicine and to the preparation of various elixirs which achieved wide acceptance.
This habit spread among the population and markets for cocaine expanded.
When the prohibitionist ideology succeeded en the United States. and arguing that cocaine had addictive character and that was potentially harmful (with prolonged administration in high doses) a political movement proposing its banning developed.
In 1906, through the Poor Food and Drug Act, this alkaloid, as well as heroin, were banned in the United States.
It was the beginning of a process that would continue throughout the century.
Despite its illegality, cocaine consumption gradually spread. As a result, coca cultivation in their areas of origin as well as clandestine laboratories for the manufacture of cocaine grew in many Latin American countries. Simultaneously transportation networks for its distribution were organized. The highly unsuccessful war on cocaine had started.

Coca derivatives
Coca leaves are usuallty processed though stepping and maceration with kerosene. Then the dry mixture is dilluted in sulfuric acid achieving a first product commonly called «coca paste» (PBC). This paste is purified by washing, particularly with ether, hydrochloric acid and acetone until obtaining cocaine hydrochloride which is the main product smuggled and commercialized in consumer countries..
Cocaine is a tropane related to Solanaceae alkaloids related (nightshade, henbane, mandragora, etc). In its usual form it is not affected by changes in temperature orlight, but requires dry environments.
It is a substance with relatively high tolerance that generates little addiction. For the nasal route the minimum active dose is about 20 to 30 milligrams, while the lethal dose is 1 to 1.5 grams.
Cocaine administered by this route has strong stimulant effects. It generates « a permanent activity without fatigue, verve and brilliance in social life, exalted and megalomania ego foolproof, attitudes preferred by executives and risk takers searches risks which is sold as a model advertising the contemporary society»
