What is Cocaine?

Cocaine is the purified chemical cocaine hydrochloride from the leaves of the coca plant, native to South America. When ingested, the chemical causes the release of dopamine in the body which gives off a feeling of euphoria. Other effects of cocaine can be an increase in confidence, energy, a rise in social abilities as well as give off a strong feeling of accomplishment. This is one of the reasons why cocaine is popular amongst Wall Street Executives. Cocaine is the most powerful central nervous stimulant found in nature.

The chemical in cocaine was only first extracted from the leaves in 1859 and began becoming popular in medical communities in the 1880s. It began being used widely in the early 1900s as the main ingredient in a lot of medical tonics to treat a wide array of diseases and was even an ingredient in an earlier version of Coca Cola. However, since it has been recognized as a highly addictive substance with a potential for abuse, it has been classified as a class 2 drug and many laws are being implemented towards preventing its use and distribution in most countries. 

In the United States, the official ban on cocaine was passed in 1922 after thousands of reported deaths each year due to cocaine use.

How Does Cocaine Work?

Cocaine essentially blocks dopamine that is released by one’s nervous system from re-dispersing itself naturally. Usually, when dopamine is released it is transferred from one neuron to another and then sent back. Cocaine blocks the dopamine from being returned to the transmitting neuron. This results in a heightened sense of Euphoria that lasts longer than nature intended. Dopamine is naturally released during the body during enjoyable activities such as eating or engaging in sexual activity. 


Cocaine can be ingested in several ways. The most common method is inhalation through the nose where the drug is absorbed into the nasal tissue and then into the bloodstream. Other methods involve rubbing the powder into the gums, smoking it in a crack form, or dissolving the cocaine in water and injecting it directly into the bloodstream. 

Cocaine use

The detectable remnants of cocaine stay in your body for different amounts of time depending on how long cocaine was used. After last use, cocaine can typically show up on a blood or saliva test for up to 2 days, a urine test for up to 3 days, and a hair test for months to years. A heavy user can test positive on a urine test for up to 2 weeks. Other factors can also influence how long cocaine stays in your system. The factors include body weight, metabolism, and frequency of use. Drinking alcohol while using cocaine may also make cocaine stay in your system longer. It is important to note that mixing alcohol and cocaine is a very dangerous combination as it increases the effects of both substances on the body. Ingesting both cocaine and alcohol causes more deaths than any other drug combination.

Is Cocaine Addictive?

When someone is not under the influence of any substances, the natural state of the body is in homeostasis. When something exciting happens dopamine is released which creates the feeling of happiness. When one uses cocaine regularly, the body becomes accustomed to the extra feeling of euphoria and acts as such. Therefore, when you are not in a state of euphoria, your body will crave to get there. This is the main reason for the highly addictive quality of cocaine. According to a 2007 study, cocaine was found to be the second most addictive drug behind heroin.

In addition to being addictive, frequent users of the drug generally need to increase their ingestion of cocaine to maintain the same high. Smoking cocaine in the form of crack (named for the sound it makes when lit) is the most addictive form of cocaine.
