Yep. But that may be understanding the case. If you're part of the anti-drug-war-industrial-complex, the worse thing in the world would be for enforcement to "go way down."

Look at state and local cops, federal prison guards and the BOP, state and local prison guards, federal prosecutors, state and local prosecutors, privately owned prisons operated under contract, government employee unions, state and local police departments receiving billions in tax dollars via "drug war" grants and gear from FedGov, companies manufacturing battering rams for those 4am no-knock SWAT drug raids, etc. Let's not forget the U.S. military and border police.

At least at the federal level, over half of prisoners are there for "drug offenses": http://www.bop.gov/news/quick.jsp

What would happen to all those jobs if non-violent "drug offenders" were released from prison? That would be a tragedy, really.
