There are a number of solutions. Nobody has an easy answer to drug addiction. It's a major problem for society that we spend a lot of time trying very hard not to address, because it is a big problem to resolve. But it needs to be recognized that drug addition is an illness, so addicts need to be put into proper programs to try to prevent use. I think that one has to accept that use is going to occur, and clearly it is occurring in the prisons. People are injecting in very unhealthy circumstances. We need to address that.
Europeans have addressed that with needle exchange schemes in prisons, and it's very interesting that most European countries are now adopting this. There's a pilot scheme in Russia. Iran has a needle exchange scheme. Kazakhstan has a needle exchange scheme. Even Moldova, which most people haven't heard of, has a needle exchange scheme in their prisons. There is no English-speaking country in the world that has a needle exchange scheme in its prisons, even though we have major drug problems.
