You're in prison and have 2 cigarettes, what are you spending then on?

I cut them in half and sell them for 1.5x their equal. I now have a starting point of 6 cigarettes to trade from. I get my boy Greg, who is a little slow in the mind, but large in body to take the cigarettes back. I pay him 12.5 %. 12.5% goes to my outside source of cigarettes. I pocket 25% and keep the economy going.
