Two-thirds of a million people who were put in jail for something that's relatively safe to use, not dangerous to others (barring the black market of supply created by its illegality), and presently legal in two of the fifty states (18 if you count medical).
That's over 650-thousand new "patients" being "referred" to drug and alcohol treatment facilities. The number of people put in jail for imbibing a plant is larger than entire the population of Vermont or Wyoming.
The number of people who's job applications will be haunted with criminal charges for the next seven to ten years, at least, is larger than the populations of all but the 19 largest cities -- larger than the populations of Boston, Seattle, Denver, Portland, Ore. and Washington D.C.
This is the prohibition your government is pursuing despite your majority opinion. Any questions?
