The process of selling drugs - either to a reseller, or the end-user - seems often called "move" in popular (American?) culture - for example in the TV Series, Weeds.
Transcripts from the show are hard to find but here's a synopsis describing an episode:
Nancy wants to move product while working the shop, so she "interviews" all her former Agrestic people to see what they can move. [...]
Where does this originate from? Does it have its roots in a more legitimate field like agriculture, or is this limited to criminal activity? It seems to be used widely in connection with smuggling (Example: Colombian traffickers moving drugs in submarines) but that is not selling.
The word definition at Merriam-Webster doesn't seem to offer any explanation.
