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»
