I have heard that prisoners use cigarettes as their currency in prison. Also some prisons have
shops inside. Prisoners dont have cash, but they have money on balance. Mostly prisoners use shop to either buy food or hygiene products. Btw, did you know, that prisoners earn while doing
prison labour? Extremely low, but still they have got some money. Money gives them variety of opportunities and things to do in prison.
It's true but based on the things they say, at least where I live some Prisoners have more money than the same people who live in society, of course the prisoners who are Older , those who enter through gangs obviously have the Financial support of those who have been under pressure for a long time, those who don't, have to find money however they can , through their family or something, sometimes even working what they earn is taken away by others.
