Alcoholism Recovery & Treatment

my girlfriend was convicted for possession of meth 7 years ago. she did some time in prison and finished a 2 year treatment program for substance abuse. she has been clean and sober now over 6 years and currently works as a residential technician at a treatment facility. she very much wants to go back to school and become a certified counselor specializing in addiction issues. she has turned her life completely around and wants to invest all of her time and knowledge into helping other addicts find recovery. what are the steps she should take to become a drug and alcohol counselor? is there a specific course outline to become one?
thanks in advance.
there is no need for negative comments concerning her past. i just want to be able to help her get into school to pursue what she calls her ‘mission in life’ to help other addicts.

I have been sober for almost 3 years and am now attending college, I am getting ready to transfer to an Univerisity and I cannot figure out my major, because of my state jail felony. I get off probation in 6 months and so far have completed probation successfully and will not be convicted, so what are my options then. I want to teach 1st grade, or become a nurse, can I totally forget about either one of those professions? What about drug and alcohol counseling???? Help!!
