Because there are other reasons extremely valid reasons why we shouldn't drug dealers and organized crime besides that they drugs they sell are ussually adulterated? I mean you couldn't even get these legal/clean drugs directly before buying something from a street dealer under this scheme? Why? IMHO that's just beyond absurd we might just as well provide direct cash subsidies to drug cartels instead if that's your goal.
