Coca Plants Cocaine is one of the most popularly used illicit drugs in the U.S., second only to marijuana. But unlike marijuana, cocaine is not produced in the U.S. All cocaine is imported. Cocaine comes from coca plants. The plants grow almost exclusively in the Northern and Western areas of South America. Most of the cocaine found in the U.S.
Comes from Colombia, but some cocaine also comes from Peru, Bolivia and Chile. There are nearly 200 species of coca plants, but only two coca varieties have significant amounts of the alkaloid used to make cocaine. These are the varieties that grow in the highest mountain altitudes. The alkaloid is contained in the coca plant's leaves. Workers continuously harvest the leaves, leaving the plant to hopefully produce more for a later harvest.
The leaves are dried and transported to secret laboratories for processing. The leaves must be transported quickly and carefully, because wet or rotting leaves cannot be used to make cocaine.
Cocaine Processing Labs The coca plants grow naturally in many regions of South America and are therefore not illegal in those areas. However, the clandestine laboratories are. A clandestine lab is a secret laboratory used to make illegal substances. Clandestine labs are often simple, makeshift operations.
The cocaine labs are hidden in the remote jungle areas of the coca growing regions. The labs are used to extract cocaine from the dried coca leaves. There are two main types of cocaine processing labs. The first is called a pozo pit lab.
It uses acidic solutions to extract cocaine from coca leaves. The second is called a metal drum lab. It uses metal drums and gasoline to extract cocaine from coca leaves and is the most common type of cocaine processing lab.
In both types of labs, the goal is to pull the cocaine alkaloid from the coca leaves. This results in cocaine base, or cocaine paste, which is a gummy substance typically containing about 50% cocaine. It's a complicated and tedious process.
Let's take a quick look at the differences in the labs. In the pozo pit labs, the leaves are put into a pit with a sulfuric acid solution. Workers then stomp on the leaves for a few hours. In the metal drum labs, the leaves are chopped up, mixed with lime and soaked in kerosene or diesel fuel. This mixture is placed in a metal drum and left for around three days but stirred often.
In both labs, the process creates cocaine sulfate. The entire mixture must still be heated, filtered, curdled and processed with sulfuric acid in order to form the cocaine base. The base is poured into brick molds and pressed to remove all liquid. The bricks are dried, resulting in hard, yellowish cocaine blocks that can be individually packaged and shipped. Though this is not the type of cocaine you'll find on the streets of the U.S. These bricks are headed to yet another lab.
The cocaine base bricks must be processed into a form that can be ingested. Processing Powder Cocaine Cocaine base bricks are shipped all over the world, wherever there is a market for cocaine. Cocaine base is often processed in the same country where the drug will be sold and used. First, let's look at how cocaine base is processed into powder cocaine. Powder cocaine is also known as crystal cocaine, or cocaine hydrochloride, and was most recently popular in the 1970s and 1980s.
This is the white, dusty form of cocaine that is usually snorted. However, it can also be injected or ingested. Cocaine base must first be dissolved in some sort of solvent, such as acetone or ether. It's then heated, mixed with another solvent and added to hydrochloric acid. It's ultimately dried to form clear or whitish cocaine hydrochloride crystals, hence the term 'crystal cocaine.'
This is a salt form of cocaine, which is water-soluble. This means it's easily absorbed into the blood stream and can be injected. This type of cocaine is usually cut, meaning it's mixed with another substance, such as cornstarch, sugar or another drug. This dilutes the cocaine and can give the final product another color. Drugs are cut in order to make more of the product and increase profits for the drug dealers. Processing Crack Cocaine Cocaine hydrochloride can be further processed to produce crack cocaine. Crack cocaine is a solid form of freebase cocaine and the most potent form of the street drug.
Crack is made by cooking powder cocaine. This evaporates the hydrochloride out of the cocaine. The residue is then dried into jagged, brownish rocks. The rock is used as a freebase, meaning it is smoked, usually by heating in a glass pipe and inhaling the vapor.
Freebase drugs often produce a faster and more intense high. Crack cocaine is thought to be cheaper, yet more addictive, than powder cocaine. By the late 1980s, the U.S.
Recognized a nationwide crack epidemic centered in lower income, urban neighborhoods. Crack is currently the most popularly used form of cocaine in the U.S. Lesson Summary Cocaine is made from coca plants, which grow almost exclusively in the Northern and Western areas of South America.
Coca leaves are plucked, dried and then processed in clandestine laboratories. A clandestine lab is a secret laboratory used to make illegal substances. Some labs are pozo pit labs, which use acidic solutions to extract cocaine from coca leaves. Most labs are metal drum labs, which use metal drums and gasoline to extract cocaine from coca leaves.
Both labs produce cocaine base, or cocaine paste, which is a gummy substance typically containing about 50% cocaine. The base is poured into molds, pressed and dried into bricks. The base can be dissolved, heated and dried to form powder cocaine. Powder cocaine is also known as crystal cocaine, or cocaine hydrochloride, and was most recently popular in the 1970s and 1980s. Powder cocaine is usually cut before being sold on the street.
This means it's mixed with another substance, such as cornstarch, sugar or another drug. Powder cocaine can be made into crack cocaine.
Crack cocaine is a solid form of freebase cocaine and the most potent form of the street drug. It's made by cooking the powder, evaporating the hydrochloride out and drying the residue into a rock. Crack is a freebase drug, meaning it's most often smoked, usually by heating in a glass pipe, and inhaling the vapor.
Learning Outcomes Once you are finished, you should be able to:. Recall where the coca plant is found. Name and describe the two types of clandestine labs used to process coca plants into cocaine. Describe how cocaine base is made into powder cocaine and crack cocaine.
Abstract Aims. To compare the prices of cocaine powder and crack cocaine in the United Stales, Design. Retail prices for crack and powder cocaine are compared for 14 US cities between 1986 and 1991 using regression analysis and t-tests. Prices are estimated from the United States Drug Enforcement Administration's System to Retrieve Information from Drug Evidence (STRIDE) database. On average, crack is neither more nor less expensive per pure unit than powder cocaine.

Prices are not equal in every city in every year, but crack is equally likely to be more or less expensive, and the differences are not large relative to -variation in prices of both forms of cocaine between cities and over time. Crack has been widely believed to be cheaper than powder cocaine, and this “fact” has been used to help explain why US drug problems worsened in the 1980s. However, crack is not, in fact, cheaper per pure unit than powder cocaine. Other explanations must be sought for why crack spread so rapidly relative to powder cocaine.
