Congressional Budget Office Cost Estimate: H.R. 313: Drug Trafficking Safe Harbor Elimination Act of 2011 [open pdf - 16KB]
"CBO [Congressional Budget Office] estimates that implementing H.R. 313 would have no significant costs to the federal government. Enacting the bill could affect direct spending and revenues; therefore, pay-as-you-go procedures apply. However, CBO estimates that any effects would be insignificant for each year. H.R. 313 would prohibit U.S. entities from assisting, supporting, or engaging in conspiracy with entities engaged in activities outside the United States that would violate the Controlled Substances Act if carried out within the United States. Under current law, it is legal to assist or invest in a manufacturing company with operations outside the United States that produces chemicals that are on the U.S. Controlled Substance list. Thus, the government might be able to pursue new cases under the bill that it otherwise would not be able to prosecute. CBO expects that H.R. 313 would apply to a relatively small number of new cases, however, so any increase in costs for law enforcement, court proceedings, or prison operations would not be significant. Any such costs would be subject to the availability of appropriated funds."
