The first commentary discusses the impact that the proposed shift in the heroin supply curve will have on social costs and drug law enforcement efforts. Because income spent for narcotics is derived largely from clandestine or coercive extraction of money (i.e., criminal activity), it is likely that the larger the percentage increase in the price of heroin achieved by law enforcement activity, the larger the redistributional costs borne by society's non-drug users will be. The author also argues that the institutional pressures and frictions set up by the market surpluses, and shortages generated by the social policy of restricting the drug trade, contribute to a decline in the quality of general law enforcement services. The second response argues that Rottenberg, in his economic analysis, has ignored the unique problems posed by drug addiction. Because punishment for drug offenses does not serve as a deterrent to the drug addict, there are no constraints on drug use, and therefore an unconstrained maximum situation emerges. Therefore, society needs to consider alternatives to reducing drug use, the most effective of which would consist of therapeutic programs, rather than traditional suppression methods.
