Organized crime is pretty well purged from Colorado (and likely Oregon and Washington as well). Prior to retail taking effect, the DEA and Colorado law enforcement flushed out anyone with even a remote relationship with, call it, persons of interest. Since then, all participants have been subjected to background checks, where the thoroughness ranges from cursory (for, say, an hourly employee) to proctological (for a license owner). There are currently strict domesticity requirements for all "owners" (broadly defined by the state enforcement agency as anyone with "control"), i.e., at least two years of residency in the state of Colorado. Then of course there is the standard clean background check. New laws under consideration would open the market to out-of-state investors as of Jan 1 2017, but those laws are awaiting the governor's signature.
