anecdotal evidence: in WA state where weed is legal, I have not heard of anyone buying weed on the street. Why would you risk it when you have good quality stuff that you can buy in a safe location?

so you decriminalize it first and after that you make it straight up legal.

Organized crime is going to move to other things in response. There is a risk/reward curve.

Absolutely, and here the reward for legalizing some drugs seems greater than the risk.

I suppose Meth and Crack are not on the list of legalized drugs, which means that half of all drug offenses will not be affected.

Still, halving drug offenses is not a bad result.
