It was unsuccessful partly due to the fact that instead of being a drug rehab facility it was instead a drug maintenance facility.  It was completely up to you weather or not you wanted to titrate off or not and for a drug abuser with the drug right in front of them, that is a difficult thing to do.  The other reason why it failed is because you are required to go to the clinic everyday to receive your medication and I lived fairly far away and it was completely the opposite way from where I worked.  So it was a huge inconvenience.  I actually believe if I was given a prescription that I could have with me I might have had a better chance of success.
