Who Treats Addiction: Types of Substance Use Specialists

What kinds of clinicians treat addiction?

Addiction medicine physicians are doctors (often trained in family medicine, internal medicine, or another specialty, then board-certified in addiction medicine) who diagnose substance use disorders, manage detox and withdrawal, and prescribe medications such as those used for alcohol or opioid use disorder.

Addiction psychiatrists are psychiatrists with extra training in substance use. They are especially helpful when addiction sits alongside another mental health condition — depression, anxiety, bipolar disorder, PTSD — because they can treat both at once.

Licensed therapists and addiction counselors (LCSWs, LPCs, psychologists, and certified alcohol and drug counselors) deliver the behavioral treatments — counseling, relapse-prevention skills, and structured therapies — that are the backbone of recovery.

Primary care clinicians are often the most accessible starting point. Health systems increasingly use a model called SBIRT — Screening, Brief Intervention, and Referral to Treatment — an evidence-based public-health approach that combines screening, a short counseling conversation, and a referral when more help is needed 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2025).SBIRT: Screening, Brief Intervention, and Referral to Treatment.SBIRT is an evidence-based, integrated public health approach combining universal screening, brief intervention, and referral to treatment for people with or at risk of substance use disorders..

What does 'addiction medicine' actually mean?

Addiction medicine is a recognized medical subspecialty. A clinician with this training treats the full range of substances — alcohol, opioids, stimulants, nicotine — and understands the medical side of dependence: how withdrawal works, when it is dangerous, and which FDA-approved medications can reduce cravings or block a drug's effects.

The field's screening-and-referral framework grew out of decades of public-health work. SBIRT is now used across primary care, emergency departments, and specialty clinics as an integrated way to catch problems early and connect people to the right level of care 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2025).SBIRT: Screening, Brief Intervention, and Referral to Treatment.SBIRT is an evidence-based, integrated public health approach combining universal screening, brief intervention, and referral to treatment for people with or at risk of substance use disorders.. Some of the most-studied brief screening questions were first developed and rigorously validated in adolescent care and later adapted more broadly 2Ref 2Knight JR, Sherritt L, Shrier LA, Harris SK, Chang G (2002).Validity of the CRAFFT substance abuse screening test among adolescent clinic patients.Brief substance-use screening instruments were rigorously developed and validated to identify substance-related problems, disorders, and dependence using a defined scoring cut point..

How is addiction treatment usually organized?

Addiction care is delivered at different intensities — sometimes called levels of care. These range from a single primary care visit, to weekly outpatient counseling, to intensive outpatient programs, to residential or inpatient treatment, which insurance may or may not cover, for people who need round-the-clock support or a medically supervised detox.

Most people do not start at the most intensive level. A clinician matches the setting to your situation, and the plan can step up or down over time. Effective treatment is also tailored to the person — what works for one individual or age group may differ for another, which is why national treatment guidance emphasizes individualized care matched to a person's needs 3Ref 3National Institute on Drug Abuse (NIDA) (2014).Principles of Adolescent Substance Use Disorder Treatment: A Research-Based Guide.Effective substance use disorder treatment should be individualized and tailored to a person's developmental and clinical needs rather than one-size-fits-all..

Why see a clinician for addiction?

A clinician adds value that self-help alone usually cannot. First, a trained provider can use a validated screening tool — like the brief, well-studied questions used in SBIRT and related screeners — to gauge how serious the problem is rather than guessing 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2025).SBIRT: Screening, Brief Intervention, and Referral to Treatment.SBIRT is an evidence-based, integrated public health approach combining universal screening, brief intervention, and referral to treatment for people with or at risk of substance use disorders.2Ref 2Knight JR, Sherritt L, Shrier LA, Harris SK, Chang G (2002).Validity of the CRAFFT substance abuse screening test among adolescent clinic patients.Brief substance-use screening instruments were rigorously developed and validated to identify substance-related problems, disorders, and dependence using a defined scoring cut point.. Second, a physician can rule out or manage the medical side: certain withdrawals (especially from alcohol or sedatives) can be dangerous and may need medical supervision. Third, clinicians can offer evidence-based treatment — counseling plus, when indicated, FDA-approved medication — matched to your needs 3Ref 3National Institute on Drug Abuse (NIDA) (2014).Principles of Adolescent Substance Use Disorder Treatment: A Research-Based Guide.Effective substance use disorder treatment should be individualized and tailored to a person's developmental and clinical needs rather than one-size-fits-all.. Fourth, they coordinate the practical pieces: connecting you to the right level of care, looping in mental health treatment when a co-occurring condition is present, and helping with work or family communication. If you are not sure where to begin, telling your primary care clinician 'I want help with my drinking or drug use' is enough to start the process.
