New Hampshire offers a wide and comprehensive array of substance use disorder treatment services across the state including evaluations, withdrawal management (detoxification), outpatient counseling, residential services, and recovery support services. Prior to accessing treatment, a thorough evaluation should be conducted by a licensed alcohol and drug counselor or a behavioral health specialist who has addiction training.

Below are examples of assessments that may be used to help identify the severity of an alcohol and/or drug problem and some of the many behavioral therapies that can be used to promote behavior change across different populations, gender, ages, and other needs.  For additional information, visit the Substance Abuse and Mental Health Services Administration (SAMHSA) and their National Registry of Evidence-based Programs and Practices (NREPP).

Co-Occurring Disorders

A co-occurring disorder is the combination of one or more mental health disorders and one or more substance use disorders. Co-occurring disorders are most effectively treated when interventions are integrated. Examples of integrated interventions include:

  • Integrated screening and assessment processes
  • Dual recovery mutual self-help meetings
  • Dual recovery groups in which recovery skills for both disorders are discussed
  • Motivational enhancement interventions that address issues related to mental health and substance use
  • Group interventions for persons with a triple diagnosis of mental health disorder, substance use disorder, and trauma, or which are designed to meet the needs of persons with co-occurring disorders and another shared problem such as homelessness or criminality
  • Combined psychopharmacological interventions in which an individual receives medication designed to reduce cravings for substances as well as medication for a mental health disorder
