I suspect there may be a network effects / regulatory arbitrage problem. If only a small number of places decriminalize drugs, that will attract lots of drug addicts without being able to support them. The policies need to be more universal in order for them to bear fruit... Though I realize this sounds like doubling down on failure. It would explain why a country wide program like Portugal could be more successful.
