I think there was sort of a formalization of territory when the Colombian cartels controlled the entire chain from production in the jungle to the sale in US streets. The violence and territorial wars in Mexico since the early 2000s are as I understand it a direct consequence of the demise of the Colombian Cali and Medellín cartels, with numerous groups trying to fill the power vacuum left. What you describe often is happening on a local level, but there will always be outbursts of violence somewhere as soon as someone threatens the "peace". Getting drugs into the US is just way too lucrative a business. The fighting will just keep shifting places as long as this is the case.
