Don't you think selling drugs is a job? It's a business. They employ people. The cartels operate the majority of legal outlets.
You're an idiot if you think that the cartels are running the legal outlets in CO. Not only do they have to have a background check BEFORE they can apply for a permit to grow and sell, but so do their employees, as well as there are many different regulations that must be complied with.
Tell ya what, go to an actual 420 store in CO and ask them how they got started, or, if you can't do that, watch some of the documentaries on the History Channel, MSNBC, or CNN, all of which have done some pretty good reporting on how it is working now.
But, if you choose to live in ignorance, carry on.
