Last I heard around the time Colorado legalized the cartels started investing into heroin and cocaine because just a handful of states alone was enough to completely wreck their shit. They tried to invest in meth, but apparently they can't compete with the US gangs already producing it since meth is a cheap drug.
It won't have an effect since they'll just move on to other criminal avenues. As more and more things get legalized, it'll eventually eat away at their power, but one plant is like a car that needs an oil change.
