Modern usage

In many countries, cocaine is a popular recreational drug. Cocaine use is prevalent across all socioeconomic strata, including age, demographics, economic, social, political, religious, and livelihood.

In the United States, the development of "crack" cocaine introduced the substance to a generally poorer inner-city market. The use of the powder form has stayed relatively constant, experiencing a new height of use across the 1980s and 1990s in the U.S. However, from 2006 to 2010 cocaine use in the US declined by roughly half before again rising once again from 2017 onwards. In the UK, cocaine use increased significantly between the 1990s and late 2000s, with a similar high consumption in some other European countries, including Spain.

The estimated U.S. cocaine market exceeded US$70 billion in street value for the year 2005, exceeding revenues by corporations such as Starbucks. Cocaine's status as a club drug shows its immense popularity among the "party crowd".

In 1995 the World Health Organization (WHO) and the United Nations Interregional Crime and Justice Research Institute (UNICRI) announced in a press release the publication of the results of the largest global study on cocaine use ever undertaken. An American representative in the World Health Assembly banned the publication of the study, because it seemed to make a case for the positive uses of cocaine. An excerpt of the report strongly conflicted with accepted paradigms, for example, "that occasional cocaine use does not typically lead to severe or even minor physical or social problems." In the sixth meeting of the B committee, the US representative threatened that "If World Health Organization activities relating to drugs failed to reinforce proven drug control approaches, funds for the relevant programs should be curtailed". This led to the decision to discontinue publication. A part of the study was recuperated and published in 2010, including profiles of cocaine use in 20 countries, but are unavailable as of 2015.

In October 2010 it was reported that the use of cocaine in Australia has doubled since monitoring began in 2003.

A problem with illegal cocaine use, especially in the higher volumes used to combat fatigue (rather than increase euphoria) by long-term users, is the risk of ill effects or damage caused by the compounds used in adulteration. Cutting or "stepping on" the drug is commonplace, using compounds which simulate ingestion effects, such as Novocain (procaine) producing temporary anesthesia, as many users believe a strong numbing effect is the result of strong and/or pure cocaine, ephedrine or similar stimulants that are to produce an increased heart rate. The normal adulterants for profit are inactive sugars, usually mannitol, creatine, or glucose, so introducing active adulterants gives the illusion of purity and to 'stretch' or make it so a dealer can sell more product than without the adulterants, however the purity of the cocaine is subsequently lowered. The adulterant of sugars allows the dealer to sell the product for a higher price because of the illusion of purity and allows the sale of more of the product at that higher price, enabling dealers to significantly increase revenue with little additional cost for the adulterants. A 2007 study by the European Monitoring Centre for Drugs and Drug Addiction showed that the purity levels for street purchased cocaine was often under 5% and on average under 50% pure.
