for me the biggest reason to have gange legal is it frees policing resources up from processing fairly ridiculous prosecutions of people dealing in what is basically just plant material.
so while it is nice to see there is no real impact on "other crime" the fact they missed the impact of freeing up resources directly related to weed is a major ommission.
and also.
god damn you americans pay a lot for it. $250 an ounce. that's ridiculous. like more than three times the price I used to pay as a teenager for prime amsterdam skunk.
