1 of 12 core functions of addiction counselling

Screening is the responsibility of an addiction counsellor to evaluate the client’s physical and mental condition prior to entering a treatment program.  The safety of the client entering the program is of utmost importance.  Thus, the addiction counsellor must assess if the client is mentally and physically capable of participating in all aspects of the treatment program at this time.  The client is screened for suicide risk, potential mental health instability, and potential withdrawal concerns.  This does not exclude the client from attending the rehab program, it just allows a safety check as to the client’s physical and mental stability.  The effects of drugs can last a long time and there is always the concern of withdrawal or mental health episodes such as psychosis.  Opiate withdrawal levels can be determined using a tool called COWS (Clinical Opiate Withdrawal Scale)  For alcohol withdrawal, AWS (Alcohol Withdrawal Syndrome) is a brief tool used, and to screen for suicide risk, the ASQ can be used. If it is found that the client is presenting with any of these challenges, then the counsellor is to notify their supervisor and make plans to refer the client to the appropriate health service agency.

Referring to agencies involved in the continuum of care such as psychiatrists, withdrawal management, hospitals, and mental health resources are imperative if the client is presenting mental or physical symptoms that are too severe for the client to participate in treatment at this time.  Assuming that the client does not have any of the above-mentioned symptoms, the addiction counsellor will move forward into the intake phase.


During the intake process the addiction counsellor will explain the treatment program policies and procedures to the client. These forms include confidentiality, ethics, consent to treatment, emergency contact information, financial contract (if applicable), release of information (family, spouse, insurance providers, health agencies), and waiver.  This is to ensure the client understands the bounds of confidentiality and their rights.

The intake can be the beginning of building trust between the addiction counsellor and the client.  During this time, the client may be hesitant, scared, experiencing anxiety or feel alone.  Therefore, the intake interaction between the addiction counsellor and the client will help further develop trust and the client’s sense of safety and well-being.  Once all intake procedures are explained and documents signed, the addiction counsellor will move forward and provide an overview of what to expect during the treatment program.


The orientation is where the addiction counsellor will provide the client with an in-depth explanation of rules, guidelines, program outline, and personal responsibilities.  Each treatment program will have varying rules and guidelines that must be outlined to the client.  During the orientation the addiction counsellor is required to provide the client with specific details about expectations of conduct i.e.; Wake up time, group time, meal time, free time, bed time, etc. The consequences of guideline infractions must also be conveyed so that the client is aware of any discharge policy or discipline for guideline infractions.

The client will be given a tour of the facility, showing them sleeping quarters, eating area, group rooms, laundry facilities, counsellor rooms, bathrooms, recreation area, exercise room, and administration office. For an outpatient program, the client will be advised of the operating hours, expectations of attending sessions, policy regarding missed sessions, and program length.  Once the orientation has been completed, the addiction counsellor will begin the process of developing a specific treatment plan by completing a comprehensive assessment of the client’s history.


In the assessment the addiction counsellor gathers specific information around the client’s life areas, such as family history, education, employment history, legal involvement, psychological well-being, physical health, relationships, and social functioning.  With the information gathered in the assessment the addiction counsellor will assess the client’s life areas to identify imbalances. Assessments often contain substance use severity tools such as MAST (Michigan Alcohol Screening Test) and DAST (Drug Abuse Screening Test).  These screening tests can help to create awareness for both the addiction counsellor and the client.

The addiction counsellor’s role is to develop a comprehensive overview of the client’s life experiences.  Along with the life areas, the addiction counsellor will ask for a complete substance use history, treatment history, gender identity, cultural beliefs, trauma history, client’s strengths and weaknesses, and any violence (including intimate partner violence).  Through the assessment the addiction counsellor can pinpoint indicators associated with attachment style, possible trauma, mental health status, and maladaptive coping strategies.

Although the addiction counsellor is not trained to diagnose clients with mental health disorders, they are trained to observe certain behaviours that can be the basis of a referral to an appropriate professional for further evaluation.  If a mental health diagnosis has been disclosed by the client, it is the addiction counsellor’s responsibility to request confirmation of diagnosis from the medical professional, with the client’s permission and document it in the assessment.  The assessment is an ongoing process. The information provides the foundation to create an individualized treatment plan.


Treatment planning is a collaborative effort between the addiction counsellor and client. Together they will create solutions to specific barriers, develop realistic goals, identify counselling methods, and formulate a comprehensive therapeutic course of action.

A unique treatment plan is created for every client.  It will outline treatment goals, and objectives, and the methods of how these goals will be achieved. A treatment plan is an individualized roadmap to recovery.  It will utilize information obtained from the assessment and initial screening to identify the best treatment modalities and methods to address the client’s upcoming treatment. The addiction counsellor is required to identify the most therapeutic treatment plan for each client, so that the client can acquire the best treatment outcome.

The client’s treatment goals will be identified and documented.  Each treatment goal will require the specific methods that will be used to achieve that particular goal. For example, a client’s goal may be to improve their relationship with their child or family member.  The specific methods could include developing functional communication skills, personal boundaries, and conflict resolution skills. The client and addiction counsellor will agree upon these methods in order to empower the client in the treatment planning process.   Supporting the client in achieving their treatment goals will be a primary role of the addiction counsellor.  The client’s acquisition of these goals will help to improve their sense of self and enhance their personal accountability.

Following any results from the screening tools and assessment, other services in the continuum of care may need to be included in the treatment plan, such as mental health professionals; psychologists, psychiatrists, registered clinical counsellor, addiction doctors, sober living facilities, after care services, therapeutic community-based networks, and faith-based services.  A treatment plan is flexible and will likely need to be adjusted throughout the course of treatment.  The addiction counsellor and client will make necessary changes based on progress and information gathered during the counselling sessions.


The goal of counselling is to assist a client in transforming problematic thought and behaviour patterns, and to develop functional coping strategies to manage emotional stressors.  The two primary approaches used in counselling are individual and group therapy.  The addiction counsellor will help the client identify their personal barriers such as guilt, shame, beliefs about self and society, relationships with loved ones and family members, and the impact that their substance abuse has had on themselves and others.  For example, the client may be unable to complete work goals or hold down a job, has strained relationships, lives in an unstable environment, fails to be accountable, and or has an inability to regulate emotions from traumatic experiences.  The goal of the counsellor is to empower the client to make the necessary changes in beliefs, behaviours, priorities, communication skills, and relationship dynamics.  In turn, allowing them to create a balance in previously unbalanced life areas. The addiction counsellor will implement counselling methods derived from the treatment plan such as but not limited to CBT (Cognitive Behavioural Therapy), DBT (Dialectical Behavioural therapy), Solution Focused Therapy ,Motivational Interviewing, CRA (Community Reinforcement Approach), Interpersonal Therapy, Trauma-Informed Practice, and Integrative

It is important to note that during early treatment one of the primary goals is to assist the client in stabilizing and containing difficult emotional disturbances, until such time that the client has developed the emotional stability and coping strategies to manage their emotions more effectively. At this critical time, it is important for the addiction counsellor to provide the client with practical emotional regulation skills, such as grounding techniques and mindful practice.  Client’s may have had traumatic experiences that led to trauma so the treatment should be left for more qualified professionals, such as; Psychologist, Registered Clinical Counsellor (RCC), Master of Counselling (MC), Licensed Clinical Psychotherapist (LCP).  It is vital that the addiction counsellor understand when they have reached the limits of their expertise, and when this occurs they are to consult their supervisor for guidance and direction.

Throughout counselling sessions, the counsellor may want to change counselling methods, and when this occurs it is important discuss the changes with the client and the reason behind the changes. The changes should be documented in case notes so that other staff and professionals working with the client are aware.  Nearing the end of a primary addiction treatment program, the addiction counsellor and client will develop a structured aftercare plan.  The aftercare plan will include a review of potential risk factors the client could face during the post-treatment transition. The aftercare plan will seek to ensure all aspects of a client’s stability will be maintained or further developed once they have returned home. A client may require a solution for finances, employment, education, housing etc. Developing an effective aftercare plan of action is vital to the client preparing for this very vulnerable time. Connecting clients with critical support services is a function of case management.


Case management is the process of the counsellor coordinating a variety of services and other support branches, such as mental health professionals, support workers, medical staff, stakeholders, financial funding agencies, employment agencies, and so forth. During treatment it can become apparent that the client requires medical testing, ongoing mental health support, or legal appointments that must be kept.  The addiction counsellor will communicate with the necessary agencies, ensuring to stay within the guidelines of confidentiality.

Addiction affects many areas of the client’s life and the more support services that are available to assist the client the better chance they have to achieve their recovery goals.  As each treatment plan is different, an addiction counsellor must be knowledgeable with the local services that are in the continuum of care (housing supports, financial aid, employment programs, family counselling services, sober living facilities, and mental health specialists).

Case management is an ongoing process throughout the treatment program.  Ensuring that the client receives all the support they require is imperative for them to have success at completing goals and maintaining recovery.  Once primary addiction treatment is complete, the client should have a solid after-care plan in place.  Leaving treatment for many clients can be scary and bring up self sabotaging behaviours.  This is where crisis intervention training becomes essential.


Crisis intervention requires the addiction counsellor to intervene when a client becomes emotionally or physically destabilised.  De-escalation is the most crucial part of crisis intervention as some crisis’ can escalate to a more severe situation such as violence or self-harm.  That being said, an addiction counsellor will experience a client in crisis.  These crisis’ can range from psychological, physical or psychiatric.  Regardless of the crisis, the addiction counsellor needs to intervene to ensure the safety of the client and others. The implementation of Crisis Intervention practices will address acute emotional and physical distress.

One of the most severe crises’ is if the client is experiencing suicidal ideations and has thought out plans to follow through on it.  This requires immediate reporting to supervisor and a call to the police and ambulance services.  No matter the crisis, it is the addiction counsellor’s job to act quickly and implement a strategic plan of action to help the client re-stabilize.  The safety of the client, other clients and staff is the priority, and proper procedural protocols must be followed and documented with a crisis report.


Client education includes information about alcohol and drug use, additional services available to the client, and other resources that will assist in the client having a more complete recovery plan.  Psychoeducational is an evidence-based therapeutic component of treatment to help clients deal with their addiction and mental health. Through an inpatient program, substance abuse education will be presented during group classes and individual counselling sessions.  During an outpatient program, along with counselling sessions, clients may be referred to additional programs such as therapeutic community-based support programs, SMART Recovery and other self-help groups, employment programs, and housing supports.

Making the client aware of these services is duty of the addiction counsellor, as many clients are not aware of what services might be available to them.  The referral process will begin to connect the client to these support services.


The referral process is implemented when the client needs additional support that the counsellor cannot provide.  Being able to match the clients with the appropriate agency will help address any of the client’s unmet needs.  The addiction counsellor must have a solid understanding of the program they are referring the client to, so this will demand ongoing research on the part of the addiction counsellor.

The addiction counsellor should have access and contact information for relevant resources to provide the client. Having the ability to seek out resources the addiction counsellor will be better able to support the client in the continuum of care.  Any referrals made will be documented according to the treatment programs policies and tracked with case notes in the clients’ file.  Often the addiction counsellor will need to provide a summary of why the client requires additional services which is the function of report and record keeping.


Report and record keeping involves administrative and documentation skills. The record keeping will allow for clear communication among other staff members who may or may not have direct contact with the client.  Staff such as support workers, financial aid office, outreach workers, medical staff and other professionals who have authorized access to ongoing report and record keeping.

Reports such as assessment, mid-term reviews, progress reports, after-care planning reports, and discharge summaries often need to be sent to certain stakeholders, i.e. insurance agencies, lawyers, medical physicians, and case managers that may be working with the client. Many staff members will be tracking client progress through case notes. Client completion of various stages of treatment will need to be reviewed and summary reports generated.  Clients will be granted access to any documented information contained in their file upon request.

Tracking of client progress allows the client and counsellor to see the progress of goals set earlier in the treatment planning function.  As stated above, there are several other agencies that will be involved in a clients’ treatment plan. Report and record keeping will provide the addiction counsellor with the ability to convey status of pertinent information when consulting other colleagues and professionals.


Consultation with other professionals can happen during regular staff meetings or case management reviews. In other circumstances there will be other outside professionals that will be consulted.  Consultation will be made with mental health agencies, medical support and various other support networks.  The addiction counsellor, staff or service agencies will get together to review a client’s case.  Again, this is where the addiction counsellor needs to be aware of any issues outside of their professional ability.  The clients well being is the most important goal for an addiction counsellor.  When the treatment program concludes, the service provided to that client does not.  The report and record keeping function keeps the communication and collaboration exchange in place in order to assist the client in their ongoing addiction recovery.

Alcohol and drug addiction rehabilitation is an ever evolving science, therefore, it is essential that the addiction counsellor keep their skills and training up to date with current treatment modalities. This will ensure that the addiction counsellor is providing the best practices and services to their clients.
