||Coca paste, called basuco in Spanish, is an intermediate step between coca leaves and purified cocaine HCl, produced by extracting coca leaves with an alkaline material such as sodium carbonate and kerosine. It is tannish, chunky, and putty-like in consistency.|
Coca paste is rarely seen outside of South American cocaine producing countries. Because it takes less processing time to create, and is both less concentrated and pure, it is sold to poorer cocaine users in these countries, similar to the way crack is the dominant form of cocaine in poor areas in the US. Basuco use/abuse is also rampant among cocaine processing plant workers.
