For one, even traditional treatment centers are incredibly ineffective by most people's standards with roughly 60% of all addicts relapsing at least once. Assuming that these centers are funded by public taxes, then I am simply wondering whether or not that kind of return is something which will be accepted by the general public. Especially when compounded by the fact that these people would be in prison and yet be prisoners second. It isn't hard for me to imagine the backlash this could have among the general public.
Don't get me wrong though. I wish the UAE the best of luck with this program but it also seems like they may not fully understand the people they are going up against. Addicts aren't rational when it comes to their dependence. There's a reason most don't make it in recovery and that's because all of the treatment in the world won't make a difference if the patient simply can't stop no matter how much they may want to. After all, the most important part of any program is that we are willing to change.
