Precursor chemicals pose an unprecedented challenge for governments and multilateral organizations seeking to mitigate the development, manufacturing, production, and distribution of illicit synthetic drugs. As opposed to most legacy drugs -- which rely on plants, harvests, favorable weather, significant and varied manual labor, and transport of bulk amounts of illicit substances across heavily-policed terrain -- synthetic drugs can be produced in laboratories all year-round using a wide variety of mostly sparsely or unevenly regulated chemicals, which can be employed at different stages of the process in rudimentary laboratories and transported in large or small amounts, often without the knowledge of the transporters themselves. The sources for these chemicals span the globe. They are currently concentrated in China, where a relatively small number of companies appear to be producing precursor chemicals, in mainly two provinces. These chemicals are marketed and sold on the internet, where an army of online providers offer well-regulated and unregulated chemicals via the Clearnet and the dark web. These marketers are sometimes extensions of these same production companies and sometimes independent. Some are also clans, which appear to own numerous production and marketing companies. The precursors are transported to Mexico via cargo ships or air cargo, traveling direct or via circuitous routes. Cargo is often mislabeled, camouflaging the contents, purpose, or amount of their shipment. In Mexico, brokers and independent buyers facilitate this trade, filing paperwork, creating fictitious companies, or bribing officials.
