Coca

The coca plant resembles a blackthorn bush, and grows to a height of . The branches are curved, and the leaves are thin, opaque, oval, and taper at the extremities. A marked characteristic of the leaf is an areolated portion bounded by two longitudinal curved lines, one line on each side of the midrib, and more conspicuous on the under face of the leaf. The flowers are small, and disposed in clusters on short stalks; the corolla is composed of five yellowish-white petals, the anthers are heart-shaped, and the pistil consists of three carpels united to form a three-chambered ovary. The flowers mature into red berries. The leaves are sometimes eaten by the larvae of the moth Eloria noyesi. == Species and evolution ==

There are two species of coca crops, each with two varieties: • Erythroxylum coca • Erythroxylum coca var. coca (Bolivian or Huánuco coca) – well adapted to the eastern Andes of Peru and Bolivia, an area of humid, tropical, montane forest. • Erythroxylum coca var. ipadu (Amazonian coca) – cultivated in the lowland Amazon Basin in Peru and Colombia. • Erythroxylum novogranatense • Erythroxylum novogranatense var. novogranatense (Colombian coca) – a highland variety that is utilized in lowland areas. It is cultivated in drier regions found in Colombia. However, E. novogranatense is very adaptable to varying ecological conditions. The leaves have parallel lines on either side of the central vein. These plants are called "Hayo" or "Ayu" among certain groups in Venezuela and Colombia. • Erythroxylum novogranatense var. truxillense (Trujillo coca) – grown primarily in the Cajamarca and Amazonas states in Peru, including for the Empresa Nacional de la Coca S.A. and export by Coca-Cola for beverage flavoring. All four of the cultivated cocas were domesticated from Erythroxylum gracilipes in pre-Columbian times, and Bohm suggested that Erythroxylum coca var. coca is ancestral, while Erythroxylum novogranatense var. truxillense is derived from it to be drought tolerant, and Erythroxylum novogranatense var. novogranatense was further derived from Erythroxylum novogranatense var. truxillense in a linear series. In addition, E. coca var. ipadu was separately derived from E. coca var. coca when plants were taken into the Amazon basin. Genetic evidence (Johnson et al. in 2005, Emche et al. in 2011, and Islam 2011) does not support this linear evolution. None of the four coca varieties are found in the wild, despite prior speculation by Plowman that wild populations of E. coca var. coca occur in the Huánuco and San Martín provinces of Peru. Recent phylogenetic evidence shows the closest wild relatives of the coca crops are Erythroxylum gracilipes and Erythroxylum cataractarum, and dense sampling of these species along with the coca crops from throughout their geographic ranges supports independent origins of domestication of Erythroxylum novogranatense and Erythroxylum coca from ancestor Erythroxylum gracilipes. == Distribution and habitat ==

The seeds are sown from December to January in small plots () sheltered from the sun, and the young plants when at in height are placed in final planting holes (), or if the ground is level, in furrows () in carefully weeded soil. The plants thrive best in hot, damp and humid locations, such as the clearings of forests; but the leaves most preferred are obtained in drier areas, on the hillsides. The leaves are gathered from plants varying in age from one and a half to upwards of forty years, but only the new fresh growth is harvested. They are considered ready for plucking when they break on being bent. The first and most abundant harvest is in March after the rainy season, the second is at the end of June, and the third in October or November. The green leaves (matu) are spread in thin layers on coarse woollen cloths and dried in the sun; they are then packed in sacks, which must be kept dry in order to preserve the quality of the leaves. As of 2023, coca cultivation has also rapidly expanded into northern Central America, in the highland areas of Honduras, Guatemala, and Belize. But there is no evidence that coca became a significant or economically important crop in these countries. Asia East Asia • Taiwan (then known as Formosa) became the second-largest producer of coca leaves in Asia before World War II, surpassed only by Java, and played a crucial role in making Japan the world's leading exporter of cocaine. South Asia • Coca has been grown in Sri Lanka (then known as Ceylon) (De Witt, 1967). Southeast Asia • Java (today part of Indonesia) became the world's leading exporter of coca leaf in the early 20th century, surpassing Peru by 1912 and maintaining this position until the late 1920s, except during World War I. Andes Coca is traditionally cultivated in the lower altitudes of the eastern slopes of the Andes (the Yungas), or the highlands depending on the species grown. Coca production begins in the valleys and upper jungle regions of the Andean region, where the countries of Colombia, Peru, and Bolivia are host to more than 98 percent of the global land area planted with coca; Coca production in Colombia takes place predominantly in the departments of Putumayo, Caquetá, Meta, Guaviare, Nariño, Antioquia, and Vichada. Bolivia's regions of Apolo, La Paz and Chapare are known for coca cultivation. Central America In 2014, coca plantations were discovered in Mexico, and in 2020 in Honduras, which could have major implications for the illegal cultivation of the plant. Since then coca production in Central America has surged dramatically. In 2022, authorities destroyed over 6.5 million coca plants in Honduras, 4 million in Guatemala, and more than half a million in southern Belize. By 2024, the number of coca plantations found and eradicated in Honduras had nearly doubled compared to the previous year, and a record number of processing labs were dismantled across the region. Unlike the Andes, where small farmers typically grow coca, cultivation in Central America is controlled by organized crime groups with backing from major foreign cartels. A 2024 study found that coca cultivation suitability increased most in northern Central America, particularly in Honduras, Guatemala, and El Salvador (collectively known as the Northern Triangle of Central America), and Belize. The study also reported that 47% of northern Central America—limited to Honduras, Guatemala, and Belize—has biophysical characteristics highly suitable for coca growing, suggesting that environmental factors are unlikely to limit the crop's spread in those countries. The latitudinal and altitudinal gradients of these countries are especially analogous to the altitudinal diversity of Colombia's coca cultivation zones, though their soils tend to fall near the upper limit of what is considered suitable for coca in Colombia. Other regions Hawaii: In December 2017, Kauai police, working with several state and federal agencies, seized 15 mature coca plants—some up to six feet tall—and one pound of hashish during a two-day operation in Kalalau Valley, on Kauai in the state of Hawaii. The coca plants are notable because they are the source of cocaine's active ingredient. Kauai Police Chief Darryl Perry described the operation as a success in the ongoing fight against illegal drugs on the island. == Pharmacological aspects ==

, the psychoactive constituent of coca The pharmacologically active ingredient of coca is the cocaine alkaloid, which has a concentration of about 0.3 to 1.5%, averaging 0.8%, The coca leaf, when consumed in its natural form, does not induce a physiological or psychological dependence, nor does abstinence after long-term use produce symptoms typical to substance addiction. Due to its alkaloid content and non-addictive properties, coca has been suggested as a method to help recovering cocaine addicts with tapering off the drug. == History ==

prepared coca leaves. This product was mainly traded in Amsterdam, and was further processed into cocaine (Dutch East Indies, before 1940). Traces of coca leaves found in northern Peru dates the communal chewing of coca with slaked lime 8,000 years back. Beginning with the Valdivian culture, , there is an unbroken record of coca leaf consumption by succeeding cultural groups on the coast of Ecuador until European arrival as shown in their ceramic sculpture and abundant caleros or lime pots. Lime containers found in the north coast of Peru date around 2000 BC as evidenced by the findings at Huaca Prieta and the Jetetepeque river valley. Extensive archaeological evidence for the chewing of coca leaves dates back at least to the 6th century AD Moche period, and the subsequent Inca period, based on mummies found with a supply of coca leaves, pottery depicting the characteristic cheek bulge of a coca chewer, spatulas for extracting alkali and figured bags for coca leaves and lime made from precious metals, and gold representations of coca in special gardens of the Inca in Cuzco. Coca chewing may originally have been limited to the eastern Andes before its introduction to the Inca. As the plant was viewed as having a divine origin, its cultivation became subject to a state monopoly and its use restricted to nobles and a few favored classes (court orators, couriers, favored public workers, and the army) by the rule of the Topa Inca (1471–1493). As the Incan empire declined, the leaf became more widely available. After some deliberation, Philip II of Spain issued a decree recognizing the drug as essential to the well-being of the Andean Indians but urging missionaries to end its religious use. The Spanish are believed to have effectively encouraged use of coca by an increasing majority of the population to increase their labor output and tolerance for starvation, but it is not clear that this was planned deliberately. Andean people first started chewing coca leaf (Ertyhroxylum) and its popularity has been spread throughout the Northern and Central Andes, making its way down to Southern Central America, including areas like Bolivia, Chile, and Argentina. The coca leaf itself includes the active cocaine alkaloid which may be released through chewing or consumed in a powder-like form. This powder is usually extracted and made from burnt plant ashes, limestone or granite, and seashells. Andean people living in Central America have used a method to withdraw the lime from the coca plant using containers with sticks and have been able to indicate whether the coca leaves were either chewed historically even though many coca leaves haven't been discovered by archaeologists. There have been numerous effects that have been noted from the coca leaf as they are milder and more concentrated compared to pure cocaine. When Andean people began to first use the coca leaf, they noticed that it could produce a "high" and can be very addictive compared to tobacco if consumed in large quantities. Many Andean and Inca civilizations used to chew the coca leaf instead of consuming it as it provided a better "high" experience. Because of its strong addiction and high, the Incas only allowed this substance within honorary celebrations and rituals. Workers dealing with rigorous tasks such as long-distance travels, and more were allowed to take the substance as it eased their hardships along the way. There is little history before Andean people and the Incas to indicate if coca was restricted before these times and what instances it was initially used in. Sometimes coca leaves from the plant were used as offerings in rituals. Due to the nature of politics and religion in the Inca Empire, wealthy inhabitants handed out coca leaves during ritual ceremonies. Coca was first introduced to Europe in the 16th century, but did not become popular until the mid-19th century, with the publication of an influential paper by Dr. Paolo Mantegazza praising its stimulating effects on cognition. This led to the invention of coca wine and the first production of pure cocaine. Coca wine (of which Vin Mariani was the best-known brand) and other coca-containing preparations were widely sold as patent medicines and tonics, with claims of a wide variety of health benefits. The original version of Coca-Cola was among these. These products became illegal in most countries outside of South America in the early 20th century, after the addictive nature of cocaine was widely recognized. In 1859, Albert Niemann of the University of Göttingen became the first person to isolate the chief alkaloid of coca, which he named "cocaine". In the early 20th century, the Dutch colony of Java became a leading exporter of coca leaf. By 1912 shipments to Amsterdam, where the leaves were processed into cocaine, reached 1000 tons, overtaking the Peruvian export market. Apart from the years of the First World War, Java remained a greater exporter of coca than Peru until the end of the 1920s. The Japanese had significant success growing coca in Formosa, and other colonial powers made relatively unsuccessful attempts, including the British in India. In recent times (2006), the governments of several South American countries, such as Peru, Bolivia and Venezuela, have defended and championed the traditional use of coca, as well as the modern uses of the leaf and its extracts in household products such as teas and toothpaste. The coca plant was also the inspiration for Bolivia's Coca Museum. ==Coca use by the Incas==

Ethnohistorical sources While many historians are in agreement that coca was a contributing factor to the daily life of the Inca, there are many different theories as to how this civilization came to adopt it as one of its staple crops and as a valued commodity. The Incas were able to accomplish significant things while stimulated by the effects of coca. The Incas did not have a graphical written language, but used the quipu, a fiber recording device. Spanish documents make it clear that coca was one of the most important elements of Inca culture. Coca was used in Inca feasts and religious rituals, among many other things. It was a driving factor in the labor efforts that Inca kings asked of their citizens, and also used to barter for other goods. Coca was vital to the Inca civilization and its culture. The Incas valued coca so much that they colonized tropical rain forests to the north and east of their capital in Cuzco so that they could increase and control their supply. The Incas colonized more humid regions because coca cannot grow above 2600 meters in elevation (coca is not frost-resistant). Coca use in labor and military service One of the most common uses of coca during the reign of the Inca was in the context of ''mit'a labor, a labor tax required of all able-bodied men in the Inca empire, and also in military service. Pedro Cieza de León wrote that the indigenous people of the Andes always seemed to have coca in their mouths. Mit'a laborers, soldiers, and others chewed coca to alleviate hunger and thirst while they were working and fighting. The results of this are evident in monumental construction and the successful expansion of the Inca empire through conquest. By chewing coca, laborers and soldiers were able to work harder and for longer periods. Some historians believe that coca and chicha'' (fermented corn beer) made it possible for the Incas to move large stones in order to create architectural masterpieces, especially ones of monolithic construction such as Sacsayhuamán. Coca use after the Spanish invasion and colonization After the Spanish invasion and colonization of the Inca Empire, the use of coca was restricted and appropriated by the Spaniards. By many historical accounts, the Spaniards made haphazard attempts to eradicate the coca leaf from Inca life. Although the Spaniards reported state-controlled storage facilities that the Inca had built to distribute to its workers, The Spanish allowed local communities to continue to use coca to endure the labor associated with working conditions. After seeing the effects and powers of the coca plant, many Spaniards saw another opportunity and started growing and selling coca themselves. == Traditional uses ==

Medicine Traditional medical uses of coca are foremost as a stimulant to overcome fatigue, hunger, and thirst. It is considered particularly effective against altitude sickness. It also is used as an anesthetic and analgesic to alleviate the pain of headache, rheumatism, wounds and sores, etc. Before stronger anaesthetics were available, it also was used for broken bones, childbirth, and during trepanning operations on the skull. Religion Coca has also been a vital part of the religious cosmology of the Andean peoples of Peru, Chile, Bolivia, Ecuador, Colombia and northwest Argentina from the pre-Inca period through to the present. Coca leaves play a crucial part in offerings to the apus (mountains), Inti (the sun), or Pachamama (the earth). Coca leaves are also often read in a form of divination analogous to reading tea leaves in other cultures. As one example of the many traditional beliefs about coca, it is believed by the miners of Cerro de Pasco to soften the veins of ore, if masticated (chewed) and thrown upon them Chewing In Bolivia bags of coca leaves are sold in local markets and by street vendors. The activity of chewing coca is called mambear, chacchar or acullicar, borrowed from Quechua, coquear (Northwest Argentina), or in Bolivia, picchar, derived from the Aymara language. The Spanish masticar is also frequently used, along with the slang term "bolear," derived from the word "bola" or ball of coca pouched in the cheek while chewing. Typical coca consumption varies between 20 and 60 grams per day, and contemporary methods are believed to be unchanged from ancient times. Coca is kept in a woven pouch (chuspa or huallqui). A few leaves are chosen to form a quid (acullico) held between the mouth and gums. Doing so may cause a tingling and numbing sensation in the mouth, in similar fashion to the formerly ubiquitous dental anaesthetic novocaine (as both cocaine and novocaine belong to the amino ester class of local anesthetics). Chewing coca leaves is most common in indigenous communities across the central Andean region, , Peru). One option for chewing coca is with a tiny quantity of ilucta (a preparation of the ashes of the quinoa plant) added to the coca leaves; it softens their astringent flavor and activates the alkaloids. Other names for this basifying substance are llipta in Peru and the Spanish word lejía, bleach in English. The consumer carefully uses a wooden stick (formerly often a spatula of precious metal) to transfer an alkaline component into the quid without touching his flesh with the corrosive substance. The alkali component, usually kept in a gourd (ishcupuro or poporo), can be made by burning limestone to form unslaked quicklime, burning quinoa stalks, or the bark from certain trees, and may be called llipta, tocra or mambe depending on its composition.

Tea '' served in a coffee shop in Cuzco, Peru Although coca leaf chewing is common only among the indigenous populations, == Commercial and industrial uses ==

In the Andes, commercially manufactured coca teas, granola bars, cookies, hard candies, etc. are available in most stores and supermarkets, including upscale suburban supermarkets. Coca is used industrially in the cosmetics and food industries. A decocainized extract of coca leaf is one of the flavoring ingredients in Coca-Cola. Before the criminalization of cocaine, however, the extract was not decocainized, and hence Coca-Cola's original formula did indeed include cocaine. Coca leaves are also found in a brand of herbal liqueur called "Agwa de Bolivia" (grown in Bolivia and de-cocainized in Amsterdam), and a natural flavouring ingredient in Red Bull Cola, that was launched in March 2008. New markets Coca has figured more prominently in the politics of Bolivia and Peru in the early 21st century. President Morales asserted that "la coca no es cocaína"—the coca leaf is not cocaine. During his speech to the General Assembly of the United Nations on September 19, 2006, he held a coca leaf in his hand to demonstrate its innocuity. Alan García, former president of Peru, has recommended its use in salads and other edible preparations. A Peruvian-based company has announced plans to market a modern version of Vin Mariani, which will be available in both natural and de-cocainized varieties. In Venezuela, former president Hugo Chávez said in a speech in January 2008 that he chews coca every day, and that his "hook up" is Bolivian president Evo Morales. Chávez reportedly said "I chew coca every day in the morning... and look how I am" before showing his biceps to his audience, the Venezuelan National Assembly. On the other hand, the Colombian government has recently moved in the opposite direction. For years, Bogotá has allowed indigenous coca farmers to sell coca products, promoting the enterprise as one of the few successful commercial opportunities available to recognized tribes like the Nasa, who have grown it for years and regard it as sacred. In December 2005, the Paeces – a Tierradentro (Cauca) indigenous community – started to produce a carbonated soft drink called "Coca Sek". The production method belongs to the resguardos of Calderas (Inzá) and takes about of coca per 3,000 produced bottles. The drink was never sold widely in Colombia and efforts to do so ended in May 2007 when it was abruptly banned by the Colombian government. Coca Colla is an energy drink which is produced in Bolivia with the use of coca extract as its base. It was launched on the Bolivian markets in La Paz, Santa Cruz, and Cochabamba in mid-April 2010.{{cite news == Literary references ==

Probably the earliest reference to coca in English literature is in "Pomona", the fifth book of Abraham Cowley's posthumously published Latin work, Plantarum libri sex (1668; translated as Six Books of Plants in 1689). In the series of Aubrey–Maturin novels by Patrick O'Brian, set during the Napoleonic wars, Dr. Stephen Maturin, a naval physician, naturalist, and British intelligence agent discovers the use of coca leaves on a mission to Peru, and makes regular use of them in several of the later novels in the series. == International prohibition of coca leaf ==

Coca leaf is the raw material for the manufacture of the drug cocaine, a powerful stimulant and anaesthetic extracted chemically from large quantities of coca leaves. Today, since it has mostly been replaced as a medical anaesthetic by synthetic analogues such as procaine, cocaine is best known as an illegal recreational drug. The cultivation, sale, and possession of unprocessed coca leaf (but not of any processed form of cocaine) is generally legal in the countries – such as Bolivia, Peru, Chile, and Argentine Northwest – where traditional use is established, although cultivation is often restricted in an attempt to control the production of cocaine. The prohibition of the use of the coca leaf except for medical or scientific purposes was established by the United Nations in the 1961 Single Convention on Narcotic Drugs. The coca leaf is listed on Schedule I of the 1961 Single Convention together with cocaine and heroin. The Convention determined that "The Parties shall so far as possible enforce the uprooting of all coca bushes which grow wild. They shall destroy the coca bushes if illegally cultivated" (Article 26), and that, "Coca leaf chewing must be abolished within twenty-five years from the coming into force of this Convention" (Article 49, 2.e). The historic rationale for international prohibition of coca leaf in the 1961 Single Convention comes from "The Commission of Enquiry on the Coca Leaf study" published in 1950. It was requested of the United Nations by the permanent representative of Peru, and was prepared by a commission that visited Bolivia and Peru briefly in 1949 to "investigate the effects of chewing the coca leaf and the possibilities of limiting its production and controlling its distribution." It concluded that the effects of chewing coca leaves were negative, even though chewing coca was defined as a habit, not an addiction. The report was sharply criticised for its arbitrariness, lack of precision, and racist connotations. Despite the legal restriction among countries party to the international treaty, coca chewing and drinking of coca tea is carried out daily by millions of people in the Andes as well as considered sacred within indigenous cultures. Coca consumers claim that most of the information provided about the traditional use of the coca leaf and its modern adaptations is erroneous. Bolivia also made a formal reservation to the 1988 Convention, which required countries to adopt measures to establish the use, consumption, possession, purchase or cultivation of the coca leaf for personal consumption as a criminal offence. Bolivia stated that "the coca leaf is not, in and of itself, a narcotic drug or psychotropic substance" and stressed that its "legal system recognizes the ancestral nature of the licit use of the coca leaf, which, for much of Bolivia's population, dates back over centuries." However, the International Narcotics Control Board (INCB) – the independent and quasi-judicial control organ for the implementation of the United Nations drug conventions – denied the validity of article 14 in the 1988 Convention over the requirements of the 1961 Convention, or any reservation made by parties, since it does not "absolve a party of its rights and obligations under the other international drug control treaties." The INCB stated in its 1994 Annual Report that "mate de coca, which is considered harmless and legal in several countries in South America, is an illegal activity under the provisions of both the 1961 Convention and the 1988 Convention, though that was not the intention of the plenipotentiary conferences that adopted those conventions." It implicitly also dismissed the original report of the Commission of Enquiry on the Coca Leaf by recognizing that "there is a need to undertake a scientific review to assess the coca-chewing habit and the drinking of coca tea." Nevertheless, the INCB on other occasions did not show signs of an increased sensitivity towards the Bolivian claim on the rights of their indigenous population, and the general public, to consume the coca leaf in a traditional manner by chewing the leaf, and drinking coca tea, as "not in line with the provisions of the 1961 Convention." The Board considered Bolivia, Peru and a few other countries that allow such practises to be in breach with their treaty obligations, and insisted that "each party to the Convention should establish as a criminal offence, when committed intentionally, the possession and purchase of coca leaf for personal consumption." In reaction to the 2007 Annual Report of the INCB, the Bolivian government announced that it would formally issue a request to the United Nations to unschedule the coca leaf of List 1 of the 1961 UN Single Convention. Bolivia led a diplomatic effort to do so beginning in March 2009, but eighteen countries out of a total of 184, those 18 being, listed chronologically: the United States, Sweden, United Kingdom, Latvia, Japan, Canada, France, Germany, Bulgaria, Slovakia, Denmark, Estonia, Italy, Mexico, Russian Federation, Malaysia, Singapore, and Ukraine, objected to the change before the January 2011 deadline. A single objection would have been sufficient to block the modification. The legally unnecessary step of supporting the change was taken formally by Spain, Ecuador, Venezuela, and Costa Rica. In June 2011, Bolivia moved to denounce the 1961 Convention over the prohibition of the coca leaf. At Bolivia's initiative, organized by Colombia and Bolivia with the support of Canada, Czech Republic, Malta, Mexico, Switzerland and OHCHR, the World Health Organization (WHO), is conducting a 'critical review' of the coca leaf. In 2025, based on its findings, the WHO may recommend changes in coca's classification under the UN drug control treaties. Since the 1980s, the countries in which coca is grown have come under political and economic pressure from the United States to restrict the cultivation of the crop in order to reduce the supply of cocaine on the international market. This effort has been politically controversial, with proponents claiming that the production of cocaine is several times the amount needed to satisfy legal demand and inferring that the vast majority of the coca crop is destined for the illegal market. As per the proclaimed view, this not only contributes to the major social problem of drug abuse but also financially supports insurgent groups that collaborate with drug traffickers in some cocaine-producing territories. Critics of the effort claim Boliviana negra, a genetically engineered type of coca, resists glyphosate herbicides and increases yields. == Legal status ==

The primary organization authorized to purchase coca leaves is ENACO S.A., headquartered in Peru. Outside of South America, most countries' laws make no distinction between the coca leaf and any other substance containing cocaine, so the possession of coca leaf is prohibited. In South America coca leaf is illegal in both Paraguay and Brazil. Netherlands In the Netherlands, coca leaf is legally in the same category as cocaine, as both are List I drugs of the Opium Law. The Opium Law specifically mentions the leaves of the plants of the genus Erythroxylon. However, the possession of living plants of the genus Erythroxylon is not actively prosecuted, even though they are legally forbidden. United States Like cocaine, coca is controlled under the Controlled Substances Act (CSA) as a Schedule II drug meaning it is a restricted drug and is illegal to process without a prescription or a DEA registration. In the United States, a Stepan Company plant in Maywood, New Jersey is a registered importer of coca leaf. The company manufactures pure cocaine for medical use and also produces a cocaine-free extract of the coca leaf, which is used as a flavoring ingredient in Coca-Cola. Other companies that have registrations with the DEA to import coca leaf according to 2011 Federal Register Notices for Importers, include Johnson Matthey, Inc, Pharmaceutical Materials; Mallinckrodt Inc; Penick Corporation; and the Research Triangle Institute. Analysts have noted the substantial importation of coca leaf into the United States, but the actual quantity is unknown because much of it is illegally imported, and there are many reports of coca leaves and coca teas being sold in the United States and being seized by the Drug Enforcement Administration throughout the States and Territories of the United States. Canada Coca leaf is listed as a Schedule I drug (most dangerous) according to the Controlled Drugs and Substances Act of Canada (S.C. 1996, c. 19) alongside Opium (Heroin) and synthetic opioid analgesics. Specifically, it lists Coca (Erythroxylon), its preparations, derivatives, alkaloids, and salts, including:(1) Coca leaves (2) Cocaine and (3) Ecgonine. Possession of a Schedule I substance is illegal and trafficking can result in punishment of up to life imprisonment. Australia Coca leaf is considered a Schedule 9 prohibited substance in Australia under the Poisons Standard (October 2015). A Schedule 9 substance is a substance which may be abused or misused, the manufacture, possession, sale or use of which should be prohibited by law except when required for medical or scientific research, or for analytical, teaching or training purposes with approval of Commonwealth and/or State or Territory Health Authorities. India Coca leaf is a controlled narcotic drug in India by the Narcotic Drugs and Psychotropic Substances Act, 1985 which is the principal legislation governing the subject. While its scientific and medical purposes are permissible in accordance with law, any other indulgence including cultivation, possession, sale, consumption, transportation, import, export, are prohibited. == See also ==
