A real cigarette makes 3 to 4 'jail' cigarettes (squares), rolled with 'papers' cut from the toilet paper wrappers (like Scott brand out in the real world). If a guard don't like you or is bucking for sergeant, he will pull off the wrapping before giving you the roll. Blazing trees or brown is smoking tobacco, green is the word for weed, at least up 'round these parts. A real cigarette is also referred to as a 'pearl'. Depending on the pod, scarcity, etc. A square runs from 1 to 3 ramens or 1 honeybun, a wee tiny joint can fetch 10 ramens or 4 to 5 honeybuns.
DISCLAIMER: For reference use ONLY :angel: Items and prices cited were in the Allegheny County Jail 10 years ago, almost. Adjust for inflation and amount guards charge to run the tobacco in.
