ABSTRACT
In the previous chapter we briefly indicated the most common organizational characteristics of crime-enterprises involved in the underground economy of illicit psychoactive substances: criminal trading networks. This common type does not exclude the existence of hierarchic organizations along the lines of patriarchal family enterprises or other types of crime-organizations, like the Sicilian or the Calabrian Mafia. These rough denotations do not provide much insight into the various ways of organizing this trade, the constraints within which the market players have to operate and the ways they cope with them. It is to these we now turn.
