text: It all depends on which facility they are at.  Usually this is brought up at their trial & sentencing hearing so they can serve out their time at a facility that can meet their needs.  Once you are in, there are a range of various programs to attend after you have "proven yourself" by following daily rules & regulations that are required.  Many inmates are required to attend daily meetings inside & outside of jail according to the wishes of the Court, or their parole and probation officers.  You usually do enough time to come out "clean".  Most "offenders" are released to "Half Way Houses", where they get 24/7 counseling, with mandatory participation.  If they fail to comply, they are returned to prison to serve out the remaining time they would have spent in the Half Way House Program.
