My preference would be to actually focus on those who are exploiting the market of offenders' vulnerability to drugs, who are making a profit on getting those drugs to inmates, and try to focus the enforcement elements on that.
If you're looking at inmates in facilities, many of them are suffering from an illness of addiction. They don't really have capacity to resist that, and they are kind of less criminally responsible, I would say, than those who are feeding that vulnerability for their own profit. I think there is an area for targeting enforcement, but I would prefer to go there than to think that the individual inmates, who don't otherwise have access to something they need, should be penalized.
