The whole issue of eliminating illicit drugs from our institutional environment is a major task that we undertake constantly. We pour many resources towards interdiction as well as intervention. In recent years, we've been making focused efforts to eliminate drugs inside our institutional environments, by improving our technology, our intelligence, and everything from dealing with enhanced scrutiny during visits and at our principal entrances, to engaging more detector dogs, to searching and seizing contraband, and even to our intervention strategies to detect the presence of drugs, and also by reducing demand for drugs through our treatment programs. Probably the heaviest participation rate in our correctional programs is in the area of substance abuse. As we know, a significant portion of our population comes in with issues regarding alcohol and drug abuse, and we provide direct interventions to reduce the demand for those as well.
So it's a major focal point for correctional efforts, both in terms of security and case management and correctional rehabilitation and community supervision afterwards. This is always an area where we constantly need to work. To achieve results, we need to continue to strengthen our efforts in this regard and continue to look for new ways of tackling this problem.
