The illegal drug trade is a global
black market consisting of the cultivation, manufacture, distribution and sale of illegal
drugs. While some drugs are
legal to possess and sell, in most jurisdictions laws
prohibit the trade of certain types of drug.The illegal drug trade operates similarly to other underground markets. Various
drug cartels specialize in the separate processes along the
supply chain, often localized to maximize production efficiency. Depending on the profitability of each layer, cartels may vary in size, consistency, and organization. The chain ranges from low-level street dealers who may be individual drug users themselves, through ethnicity-based
street gangs and
contractor-like
middlemen, up to multinational empires that rival governments in size.
