I have to say "crutch for a crutch".
Your giving the users something else to get hooked on.  So many flaws with this program.  I don't want my hard earned money being wasted on inmates because they have an addiction problem.  I don't want my hard earned money being wasted on low income people going to the doctor with their medicaid....which i am paying for.............so they can get their next fix in a more economical fashion for their budgets.  My opinion doesn't come from lack of education.  I'm very educated on this issue.  Inmates should have no special treatment.  They are in there for a crime not to be waited on hand and foot.  Users should have to go to a treatment facility to detox.  There are enough programs out there that can take ANYBODY of any income level to assist with this.  Stop with all the band-aids to try and fix an issue.  Stop pushing for the pharmaceutical companies.
