I think that the new tools have made it more difficult for people who want to bring drugs into the institutions. I sincerely believe that the drug-detecting dogs, the Ionscan detection devices and the urine tests are tools that make it more difficult to bring drugs in.
But, by doing that, are we going to resolve the problem completely? No. Even in our own society on the outside, we are spending billions of dollars on the war against drugs. Have we managed to eliminate it completely? No.
