They don't need to do that. The majority of (monetary) value add in the supply chain is large-scale refinement and transportation of the drug product from a region of lower economic value to a region of higher economic value (i.e smuggling). Both the production and last-mile distribution are very decentralized and limited in terms of monetary compensation. If you've already made 95% of your profit in the central steps of the value chain, taking an increased risk to increase efficiency of last mile distribution is not worth it. Especially when centralization in an uber for drug dealers type of application heavily increases the risk of being neutralized and prosecuted by law enforcement rather than decentralized street level dealers who can never effectively compromise those higher up in the supply chain.
