Corrections has spent an inordinate amount on interdiction measures to try to prevent drugs from going into penitentiaries. We have spent hundreds of millions of dollars on all sorts of initiatives, and those initiatives have not yielded the results that we would expect.
The evidence shows, for example, that random urinalysis tests that are positive have not changed dramatically or significantly since we spent this inordinate amount. It's usually around 6% or 7% of all random urinalyses that come back positive, despite all the money that has been spent on interdiction measures.
I agree with you that more has to be done in world-class programming and treatment for addiction in prison, as well as much better harm reduction strategies, including health care driven needle exchanges in prisons.
