So here is an intersting conundrum, if you look at the distribution of money in the illegal drug business vs the legal drug business, the illegal side provides more jobs for people that the legal drug business won't hire. Ex-felons in general are a case which was recently called out in Richmond California.
Economics aside though, if you use the end of prohibition as an example of what might happen, you might over estimate the speed of commercialization. This is because prior to prohibition there was a thriving liquor business, and that business simply returned (within one generation so people who had run legal liquor stores before where around to run them again). This situation does not exist for drugs, medical pot clubs not withstanding.
