Certainly.
As I said, detection is a big key. You know you have a good handle on the drug trade when you start seeing lots of brew being made in jail. They make home brew. That's an indication. That's almost, as correctional officers, what we strive for. I say that jokingly, but when you see more brew in jail, you know you're starting to dry up some of the drug trade. That being said, an inmate on brew is probably not that much easier to deal with than an inmate on drugs. Certainly, that's our goal. That's the goal of every officer going into work every day, to stop and find that contraband and those things that they're doing.
In answer to part of your question, in my experience, inmates coming into an institution are predator or prey. I've found that when that inmate hits 40 or 45 years old, if he was a predator, he now sees himself as prey and looks over his shoulder and sees the young guys coming in. That's when he really doesn't want to be in prison anymore. That's when he's tired of being in prison. That's when he's going to say, “I'm going to abstain because I want out.” Until most inmates reach that predator to prey point, wherever they fit in there, it's a little more difficult for them, or the temptation is, when it's there.
