I don't think gangs are just going to dump their drug-distributing ways, let alone their spats of violence, because their goods are available over the counter. If anything, there's a risk of more active gangs to retaliate against businesses to protect their "supply chain" and "profit margins" or the gang will just switch to a less reputable drug to push, one that's not legal. It's difficult to say in those regards as California, borrowing your locale, only just recently passed its legalization; it'd be better to check back in a few months and evaluate the situation then.
I'm very much wary to these "taking everything on itself to make things cheaper" arguments because I've yet to see anyone actually explain how they'd do this. They give a vague answer about "cutting waste and fraud," as if the amount of waste and fraud in the system must be so great that it dwarfs the output of the system by many times. Or that optimizing these factors will lead to (in the case of health care) more survival stories as opposed to "the ones that got away." Additionally, do you realize how many business jobs can be killed through optimization without actually affecting productivity?
