NCRS · Get comfortable with the vocabulary.

Tolerance

A need for noticeably larger amounts of a substance to achieve the effect once produced by smaller amounts, or clearly reduced effect when the usual amount is taken. It is a physiological sign of adaptation, not by itself a diagnosis.

Related: Withdrawal, Substance Use Disorder Criteria
Withdrawal

A substance-specific set of physical and psychological symptoms that appear when heavy or prolonged use stops or is reduced. Symptoms cause distress or impairment and are central to assessing physiological dependence and need for medical management.

Related: Tolerance, Medically Managed Detoxification
Substance Use Disorder Criteria

The grouped symptoms spanning impaired control, social impairment, risky use, and pharmacological indicators used to classify severity. Meeting two or three criteria indicates mild, four or five moderate, and six or more severe disorder, guiding level-of-care decisions.

Related: Tolerance, Withdrawal, Screening, Brief Intervention, and Referral to Treatment
Screening, Brief Intervention, and Referral to Treatment

A public-health approach that uses validated short questionnaires to find risky substance use, delivers brief motivational conversations, and refers people who need more care. It is designed for general settings such as primary care and emergency departments.

Related: Substance Use Disorder Criteria, Motivational Interviewing
CAGE Questionnaire

A four-item screen asking about cutting down, annoyance at criticism, guilt about use, and morning eye-openers. It is quick and memorable but has limited sensitivity for lower-risk drinking, so positive results require fuller assessment.

Related: Screening, Brief Intervention, and Referral to Treatment, Clinical Interview
Clinical Interview

A structured or semi-structured conversation that gathers history, current symptoms, functional impact, and risk information. It anchors diagnosis and treatment planning and is supplemented, not replaced, by standardized instruments and collateral reports.

Related: CAGE Questionnaire, Differential Diagnosis, Biopsychosocial Assessment
Differential Diagnosis

The process of systematically comparing conditions that could explain a presentation and ruling alternatives in or out. In addiction work it distinguishes substance effects, psychiatric disorders, medical illness, and medication side effects before settling on a diagnosis.

Related: Clinical Interview, Co-occurring Disorders, Withdrawal
Biopsychosocial Assessment

A comprehensive evaluation of biological, psychological, and social factors that shape a person's substance use and recovery. It covers medical status, mental health, family, employment, legal issues, and supports, forming the foundation for individualized treatment planning.

Related: Clinical Interview, Treatment Plan, Recovery Capital
Assessment Instruments

Standardized tools such as the Addiction Severity Index or AUDIT that quantify problem severity and change over time. They improve reliability and outcome tracking but must be interpreted alongside interview data and cultural context.

Related: Biopsychosocial Assessment, Screening, Brief Intervention, and Referral to Treatment
Treatment Plan

A written, individualized document stating problems, goals, measurable objectives, interventions, responsible staff, and target dates. It is developed collaboratively with the client, reviewed regularly, and revised as needs and progress change.

Related: Biopsychosocial Assessment, Level of Care, Relapse Prevention Plan
Level of Care

The intensity of services matched to a person's clinical needs, ranging from outpatient and intensive outpatient to residential and medically managed inpatient care. Placement considers withdrawal risk, medical and psychiatric stability, and recovery environment.

Related: Treatment Plan, Medically Managed Detoxification, Continuing Care
Motivational Interviewing

A collaborative, person-centered counseling style that strengthens a client's own reasons for change by exploring and resolving ambivalence. It uses open questions, affirmations, reflective listening, and summaries while avoiding confrontation and premature advice.

Related: Stages of Change, Screening, Brief Intervention, and Referral to Treatment, Cognitive Behavioral Therapy
Stages of Change

A model describing movement through precontemplation, contemplation, preparation, action, maintenance, and sometimes termination or relapse. Interventions are matched to stage, so pressuring a precontemplator toward action is usually counterproductive.

Related: Motivational Interviewing, Relapse Prevention
Cognitive Behavioral Therapy

A structured therapy targeting the thoughts, beliefs, and situations that trigger and maintain substance use. Clients learn to identify high-risk cues, challenge permissive thinking, and practice coping skills, often through homework and behavioral rehearsal.

Related: Relapse Prevention, Motivational Interviewing, Coping Skills
Relapse Prevention

A set of strategies that help clients anticipate high-risk situations, recognize early warning signs, and use coping responses before a full return to use. It treats lapses as learning opportunities and includes lifestyle balance and emergency planning.

Related: Relapse Prevention Plan, Coping Skills, Stages of Change
Relapse Prevention Plan

A concrete written plan naming personal triggers, warning signs, coping steps, supportive contacts, and emergency actions. It is created with the client before discharge and shared with family or sponsors when the client consents.

Related: Relapse Prevention, Continuing Care, Recovery Capital
Coping Skills

Learned behaviors and thinking strategies used to manage cravings, stress, and high-risk situations without substances. Examples include urge surfing, delay and distraction, assertive refusal, problem solving, and reaching out for support.

Related: Relapse Prevention, Cognitive Behavioral Therapy
Continuing Care

Ongoing services after an initial treatment episode, such as outpatient groups, recovery coaching, or sober living. It supports gains made in treatment and reduces the likelihood of relapse during the vulnerable transition period.

Related: Level of Care, Relapse Prevention Plan, Recovery Capital
Medically Managed Detoxification

Supervised withdrawal management with medical monitoring and medication for people at risk of dangerous withdrawal, such as from alcohol, benzodiazepines, or opioids. It stabilizes the person but is not by itself sufficient treatment for the disorder.

Related: Withdrawal, Level of Care
Informed Consent

A client's voluntary agreement to assessment or treatment after receiving understandable information about purpose, risks, benefits, alternatives, and the right to refuse. It is an ongoing process, not a one-time signature, and must be documented.

Related: Confidentiality, Mandated Reporting, Professional Boundaries
Confidentiality

The ethical and legal duty to protect client information from unauthorized disclosure. In substance use treatment it is reinforced by federal rules that generally require written consent before sharing identifying information, with limited exceptions.

Related: Informed Consent, Mandated Reporting, Duty to Warn
Mandated Reporting

The legal obligation to report suspected child abuse or neglect, and in some jurisdictions other harm to vulnerable adults, to designated authorities. Counselors must know their jurisdiction's rules and inform clients of limits to confidentiality early.

Related: Confidentiality, Duty to Warn
Duty to Warn

A legal and ethical obligation, where recognized, to take protective action when a client poses a serious threat of violence to an identifiable person. Actions may include warning the intended victim and notifying authorities, following jurisdiction-specific standards.

Related: Mandated Reporting, Confidentiality
Professional Boundaries

The limits that keep the counselor-client relationship focused on the client's welfare. They prohibit sexual or exploitative relationships, discourage dual roles, and guide self-disclosure, gifts, and contact outside sessions to prevent harm and role confusion.

Related: Informed Consent, Clinical Supervision
Clinical Supervision

Ongoing oversight and guidance of a counselor's work by a qualified supervisor, supporting skill development, ethical practice, and self-awareness. It includes case review, feedback, and attention to countertransference and burnout.

Related: Professional Boundaries, Countertransference
Countertransference

The counselor's own emotional reactions, biases, and unresolved issues stirred up by a client. Recognizing it through supervision prevents it from distorting assessment, boundaries, and treatment decisions.

Related: Clinical Supervision, Professional Boundaries
Cultural Humility

An ongoing stance of openness, self-reflection, and curiosity about clients' cultural identities and how these shape their experience of substance use and services. It reduces bias and supports adapting interventions rather than applying one template.

Related: Biopsychosocial Assessment, Person-Centered Care
Recovery Capital

The total resources a person can draw on for recovery, including social supports, physical health, housing, employment, skills, and hope. Assessment of recovery capital guides strengths-based planning and identifies gaps to address.

Related: Recovery-Oriented Systems of Care, Peer Recovery Support, Continuing Care
Recovery-Oriented Systems of Care

A coordinated network of services and community supports organized around long-term recovery, not only acute treatment. It emphasizes person-centered goals, choice, continuity, and partnerships among clinical, peer, housing, and employment resources.

Related: Recovery Capital, Peer Recovery Support, Continuing Care
Peer Recovery Support

Assistance delivered by trained people with lived experience of recovery who offer hope, practical help, and connection to community resources. Peers complement clinical care and follow clear role boundaries and supervision structures.

Harm Reduction

Practical strategies that reduce the health and social harms of substance use without requiring abstinence, such as naloxone distribution, sterile supplies, and safer-use education. It meets people where they are and can serve as a bridge to further care.

Related: Overdose Prevention, Motivational Interviewing
Overdose Prevention

Education and supplies that reduce overdose death, including recognizing signs, calling emergency services, and administering naloxone for opioids. Counselors also address polysubstance use and teach clients to avoid using alone.

Related: Harm Reduction, Medication for Opioid Use Disorder
Medication for Opioid Use Disorder

Use of medications such as buprenorphine, methadone, or naltrexone, combined with counseling, to reduce cravings, prevent withdrawal, and lower overdose risk. These medications are evidence-based treatment, not a substitute for recovery.

Related: Overdose Prevention, Withdrawal, Co-occurring Disorders
Co-occurring Disorders

The presence of a substance use disorder together with one or more mental health conditions in the same person. Best practice is integrated treatment that addresses both conditions at once rather than sequentially.

Related: Integrated Treatment, Differential Diagnosis, Trauma-Informed Care
Integrated Treatment

A single coordinated program that combines mental health and substance use interventions, delivered by a consistent team with one plan. It avoids fragmented referrals and is associated with better engagement and outcomes for co-occurring conditions.

Related: Co-occurring Disorders, Treatment Plan, Trauma-Informed Care
Trauma-Informed Care

An approach that assumes widespread trauma, prioritizes safety, trust, choice, and empowerment, and avoids practices that retraumatize. Staff recognize trauma symptoms, build supportive relationships, and prevent coercive or shaming interactions.

Related: Co-occurring Disorders, Person-Centered Care, Integrated Treatment
Person-Centered Care

Treatment shaped by the client's values, preferences, and goals, with the client as an active partner in decisions. It supports autonomy, respects cultural context, and tailors interventions to the individual rather than to a fixed program script.

Related: Cultural Humility, Trauma-Informed Care, Treatment Plan
Adolescent-Specific Considerations

Factors that shape assessment and treatment for young people, including developmental stage, family involvement, legal consent rules, school context, and peer influence. Confidentiality limits and family engagement require careful, transparent negotiation.
