This paper synthesizes prevailing theories on optimal crime control, recidivism, and analyses of the determinants of drug use and offers suggestions to improve correctional efficiency through alternative means of drug prohibition punishments. It is likely that reduced crime rates, recidivism rates, inmate populations, and correctional costs without significant negative externalities could result from alterations in drug prohibition laws and enforcement policies. The decriminalization of all or most illicit drugs is suggested to be the most efficient means of controlling illicit drug use and should reduce the resources necessary for the maintenance of drug control policy.
