Are cigarettes allowed in jail?

Cigarettes have been largely banned across all prison and jail types. Federal outlawed them over 10 years ago and the states and county jails have mostly followed suit. As we write this, we cannot find any that still allow them. BUT, that doesn't mean that the inmates have stopped smoking. Cigarettes are sold inside for $2.00 each, the penalty for getting caught is a few days in the SHU.
