The New Prison Currency

From the Web:

You know how in movies and TV shows about prison, inmates use cigarettes as currency? That's apparently not the case in Florida. The preferred jailhouse currency across the Floridapenal system is Mrs. Freshley's Grand Honey Buns.

I think smoking must be illegal in prison so something had to replace cigarettes as a currency.  Students often don't understand that money is fiat.  This article shows that a currency would develop in the absence of government.
