Cocaine

Cocaine (benzoylmethyl ecgonine) is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant. The name Cocaine comes from "coca" in addition to the alkaloid suffix -ine, forming cocaine. Cocaine is both a stimulant of the central nervous system and an appetite suppressant. Specifically, it is a dopamine reuptake inhibitor, a norepinephrine reuptake inhibitor and a serotonin reuptake inhibitor. Because of the way cocaine affects the mesolimbic reward pathway, cocaine is addictive. Nevertheless, cocaine is used in medicine as a topical anesthetic, even in children, specifically in eye, nose and throat surgery. See also cocaine use and cocaine addiction.

Coca leaf

For over a thousand years South American indigenous peoples have chewed the coca leaf (Erythroxylon coca), a plant that contains vital nutrients as well as numerous alkaloids, including cocaine. The leaf was, and is, chewed almost universally by some indigenous communities—ancient Peruvian mummies have been found with the remains of coca leaves, and pottery from the time period depicts humans, cheeks bulged with the presence of something on which they are chewing. There is also evidence that these cultures used a mixture of coca leaves and saliva as an anesthetic for the performance of trepanation.

Appearance

Cocaine in its purest form is a white, pearly product. Cocaine appearing in powder form is a salt, typically cocaine hydrochloride. Street market cocaine is frequently adulterated or “cut” with various powdery fillers to increase its weight; the substances most commonly used in this process are baking soda; sugars, such as lactose, dextrose, inositol, and mannitol; and local anesthetics, such as lidocaine or benzocaine, which mimic or add to cocaine's numbing effect on mucous membranes. Cocaine may also be "cut" with other stimulants such as methamphetamine. Adulterated cocaine is often a white, off-white or pinkish powder.

The color of “crack” cocaine depends upon several factors including the origin of the cocaine used, the method of preparation – with ammonia or baking soda – and the presence of impurities, but will generally range from white to a yellowish cream to a light brown. Its texture will also depend on the adulterants, origin and processing of the powdered cocaine, and the method of converting the base. It ranges from a crumbly texture, sometimes extremely oily, to a hard, almost crystalline nature.

Forms of cocaine

Cocaine sulfate is produced by macerating coca leaves along with water that has been acidulated with sulfuric acid, or an aromatic-based solvent, like kerosene or benzene. This is often accomplished by placing the ingredients into a vat and stomping on them, in a manner similar to the traditional method for crushing grapes.

Freebase is the base form of cocaine, as opposed to the salt form of cocaine hydrochloride. Whereas cocaine hydrochloride is extremely soluble in water, cocaine base is insoluble in water and is therefore not suitable for drinking, snorting or injecting. Whereas cocaine hydrochloride is not well-suited for smoking because the temperature at which it vaporizes is very high and close to the temperature at which it burns; cocaine base vaporizes at a much lower temperature, which makes it suitable for inhalation.

Crack cocaine in its creation process, due to the dangers of using ether to produce pure freebase cocaine, cocaine producers began to omit the step of removing the freebase cocaine precipitate from the ammonia mixture. Typically, filtration processes are also omitted. The end result of this process is that the cut, in addition to the ammonium salt (NH4Cl), remains in the freebase cocaine after the mixture is evaporated.

Chewed/eaten coca leaves are typically mixed with an alkaline substance (such as lime) and chewed into a wad that is retained in the mouth between gum and cheek (much in the same as chewing tobacco is chewed) and sucked of its juices.

Insufflation (known colloquially as "snorting," "sniffing," or "blowing") is the most common method of ingestion of recreational powdered cocaine in the Western world. The drug coats and is absorbed through the mucous membranes lining the sinuses. When insufflating cocaine, absorption through the nasal membranes is approximately 30–60%, with higher doses leading to increased absorption efficiency.

Drug injection provides the highest blood levels of drug in the shortest amount of time. Upon injection, cocaine reaches the brain in a matter of seconds, and the exhilarating rush that follows can be so intense that it induces some users to vomit uncontrollably.

Smoking freebase or crack cocaine is most often accomplished using a pipe made from a small glass tube, often taken from "Love roses," small glass tubes with a paper rose that are promoted as romantic gifts. These are sometimes called "stems", "horns", "blasters" and "straight shooters".

Coca herbal infusion (also referred to as Coca tea) is used in coca-leaf producing countries much as any herbal medicinal infusion would elsewhere in the world. The free and legal commercialization of dried coca leaves under the form of filtration bags to be used as "coca tea" has been actively promoted by the governments of Peru and Bolivia for many years as a drink having medicinal powers.

Oral cocaine has been used medically and informally as an oral anesthetic. Many users rub the powder along the gum line, or onto a cigarette filter which is then smoked (called a "hoolie"), which numbs the gums and teeth - hence the colloquial names of "numbies", "gummers" or "cocoa puffs" for this type of administration. This is mostly done with the small amounts of cocaine remaining on a surface after insufflation. Another oral method is to wrap up some cocaine in rolling paper and swallow it. This is sometimes called a "snow bomb."
