You must not be in the states then, because those states where it has been legalized recreationally, and is being sold in stores, have regulated it heavily.
Most of the grow houses in the US are owned by corporations who are heavily invested in the science of growing pot, producing better and smoother strains. Organized crime (and those smaller dealers) who were selling in the early 2000s and 90s have basically been pushed out by these companies. Mainly because their dirt weed from Mexico sucks, and for a little more cash, people can buy stuff ten times better. Not to mention that people feel safer buying from a well lit store than some rando in his car in a Walmart parking lot (or worse his shitty apartment).
Now you can still find some "private" unlicensed dealer in my state, but these are guys who have basically been growing pot for fun, for decades, and generally have no ties to the former organized crime dealers. Mostly they only sell to close friends and family, and have never "worked a corner".
So I'm afraid I don't really follow what you are saying. The Cartels certainly haven't thrown on a friendly business suit to start up chains of budhuts, they have just stopped selling pot because they can't compete with the legitimate corporations.
Well, I won't dismiss that it's possible that some criminals have went legit, but they certainly won't be doing any of the things they were doing when they were dealing out of backpacks, because one whiff of criminality in this new legal industry and they are done for. None of these corporations want to lose the cash cow that is legal marijuana, by gaining to much attention from the state government.
And the state is watching, very closely.
