Jail is a piece of piss mate. All inmates can have their cells fully equipped with all the latest gadgets. Everyone can have a mobile phone smuggled in but it costs £500, people on the outside usually pay it. Subby's or Subatex tablets are what the majority of inmates take to get through jail, especially heroin addicts. These generally cost £2.50 but in jail it's £40 just for one. I know that not even 6 months ago a parcel was going over the wall at Durham, on a Tuesday night full of drugs. People can make a hell of a lot of money in jail.
