Social network and sociocultural approaches generally dominate current research on illicit drug markets. The main argument of these perspectives is that networks and social norms are more important elements than organization in drug markets. However, there is a need to understand aspects of interaction in drug markets that actors explicitly make decisions about - aspects that are the result of organization - alongside the emergent aspects emphasized in the social network and sociocultural approaches. In this conceptual article, we argue that partial organization theory offers a much-needed complement to existing approaches, and is useful in understanding how different groups, gangs, networks, states and market organizers in drug markets use decisions to organize their activities and the market as such.
