"An additional cocaine-control dollar generates societal cost savings of 15 cents if used for source-country control, 32 cents if used for interdiction, and 52 cents if used for domestic enforcement. In contrast, the savings from treatment programs are larger than control costs: an additional cocaine-control dollar generates societal cost savings of $7.48 if used for treatment."
