I'm back. To get your CARN certification ;http://www.intnsa.org/certifications. Some employers will allow you to obtain this within 6 mos etc. There is a very nice detox/rehab hospital in Brighton MI.
It would be to your advantage to have C.A.R.N.. aka; certification in addiction/rehab nursing I'm not sure of the website you need to go to but I'll see if I can find it and get back with you.
