In New Hampshire, alcohol and drug use counselors have been the primary providers of addiction services. The purpose of this chapter is to protect and benefit the public by setting standards of qualifications, education, training, and experience for those who seek to obtain a certificate as a certified recovery support worker or a license as a licensed alcohol and drug counselor or a master licensed alcohol and drug counselor and to promote competency in alcohol and other drug use prevention, intervention, and treatment services and in co-occurring disorder treatment services.
