My son has done the short private rehabs (30 days) a few times and relapsed shortly after. Then we sent him to a private 30 day program that was wonderful. And they recommended he go to another state for a long term program. He was in that program a year. Some allowed smoking but no coffee some allowed both. Long story short he relapsed and now is in a state run rehab for a year. I don't know if it was the hitting bottom (I hope) or the fear of going to jail if he screws up but he is getting a lot out of this program and seems to be thriving in the strict environment. We have spent thousands on rehabs and this one is just as good as any of them. One thing we have learned is they need a long term program and it is best if they do not come home. They should be in a sober living house with other people in recovery. They will find the support they need there. There is no short cuts to recovery they have to want it and be willing to do the work.
