> The skills required to run a legal drugs business are almost entirely different to those required to run an illegal drugs business.
Which, incidentally, doesn't stop at the lower-level employees but goes the whole way to the top, and is one reason it is quite likely that the "newly legal mary jane barons" won't be the same as the pre-legalization illegal barons, they'll be existing ag/pharma megacorps, who are set up to do what a legal business in the field will need to do (including already being plugged in with the applicable regulatory bodies.)
If you run "the happy weed co", violent uneducated thugs are the last people you want doing your customer service.
If this were the case , former drug dealers would be being offered jobs as pharma reps.
