Free base (freebase, free-base) is a descriptor for the neutral form of an amine commonly used in reference to illicit drugs. The amine is often an alkaloid, such as nicotine, cocaine, morphine, and ephedrine, or derivatives thereof. Freebasing is a more efficient method of self-administering alkaloids via the smoking route.
In South America, coca paste, also known as cocaine base and, therefore, often confused with cocaine sulfate in North America, is relatively inexpensive and is widely used by low-income consumers. The coca paste is smoked in tobacco or cannabis cigarettes and use has become widespread in several Latin American countries.
Methylecgonidine (anhydromethylecgonine; anhydroecgonine methyl ester; AEME) is a chemical intermediate derived from ecgonine or cocaine.. Methylecgonidine is a pyrolysis product formed when crack cocaine is smoked, making this substance a useful biomarker to specifically test for use of crack cocaine, as opposed to powder cocaine which does not form methylecgonidine as a metabolite.

Drug precursors, also referred to as precursor chemicals or simply precursors, are substances used to manufacture illicit drugs. Most precursors also have legitimate commercial uses and are legally used in a wide variety of industrial processes and consumer products, such as medicines, flavourings, and fragrances.
In 2005, scientists found surprisingly large quantities of benzoylecgonine in Italy's Po River and used its concentration to estimate the number of cocaine users in the region. [4] In 2006, a similar study was performed in the Swiss ski town of Saint-Moritz using wastewater to estimate the daily cocaine consumption of the population. [ 5 ]
About 1.9% (2.3 million) of young adults (15–34 years old) have used cocaine in the last year (latest data available as of 2018). [160] Usage is particularly prevalent among this demographic: 4% to 7% of males have used cocaine in the last year in Spain, Denmark, the Republic of Ireland, Italy, and the United Kingdom.
