In reply to balmybaldwin:
I think the problem is insoluble. We need to lock people up in prison to keep them away from the rest of society, but I imagine being inside is both very depressing, and very, very boring. In which case, it's entirely rational to want to be off your face for as much of that time as possible. That's exactly what I would do.
So, there's a massive demand for drugs in prisons, for completely rational reasons. The cheaper and stronger and more easily available the better, hence 'spice' (synthetic cannabis) being the drug of choice these days. I think it's fair to assume that you don't want party drugs that make you sociable and horny when you're in prison, you want something that's going to take you away from the grim external reality into some different, internal world. Heroin would be ideal but it's expensive. Spice will do the trick as it's just weird, and gets you fully out of it for a bit. I'm surprised strong benzos aren't more in vogue (they probably are, but the press haven't picked up), as not giving a f*ck, and being asleep would be very desirable states to achieve in that environment.
If you think it's easy to keep drugs out of prisons, you're naive. If you think people won't desperately want to be f*cked up all day in jail, then you're naive. There's no money to keep the drugs out. You can't reduce demand without making prison an enjoyable holiday camp. The problem is intractable.
