Connecticut regulates substance abuse counseling as the practice of alcohol and drug counseling and issues two state credentials under C.G.S.
20-74s: the Certified Alcohol and Drug Counselor (CADC), a certificate with no degree requirement, and the Licensed Alcohol and Drug Counselor (LADC), which adds a master's degree.
Both require 360 education hours, 300 practical training hours, three years of supervised experience and the IC&RC exam administered by the Connecticut Certification Board.
Practice is protected, with exceptions.

The Certified Alcohol and Drug Counselor (CADC), a state certificate, and the Licensed Alcohol and Drug Counselor (LADC), a state licence.
The Connecticut Certification Board separately certifies CAC and AADC credentials.
Both state credentials are issued by the Connecticut Department of Public Health under C.G.S.
20-74s.
The Connecticut Certification Board (CCB), a private IC&RC member board, administers the exam and issues its own separate private credentials.
CADC: no degree required.
LADC: a master's degree in social work, marriage and family therapy, counseling, psychology or a related field approved by the commissioner, including a minimum of 18 graduate semester hours in counseling or counseling-related subjects.
300 hours of supervised practical training plus three years of supervised paid work experience or unpaid internship; a master's degree may be substituted for one year.
No hour total is stated for the three years.
The statute requires a department prescribed examination; DPH verifies successful completion of the IC&RC International Certification Examination for Alcohol and other Drug Abuse Counselors, administered by the CCB and offered four times per year.
The LADC practice definition includes clinical evaluation of substance use and co-occurring disorders, including screening, assessment and diagnosis.
The CADC's own practice definition covers methods that assist individuals or groups and contains no diagnosis language.
20-74s(t) exempts licensees of seven professions β physicians and surgeons, psychologists, marital and family therapists, clinical social workers, professional counselors, APRNs and RNs β when acting within their licences' scope and not holding themselves out as credentialed under 20-74s.
20-74s(w) also exempts paid counselors working under supervision, but 20-74s(x) requires Department of Correction substance abuse counselor and supervisor positions to be credentialed, apart from (u) interns and trainees and people completing the (e) supervised paid work experience.
DPH deems applicants certified by an IC&RC/AODA member board to have met the education, training and experience documentation, and 20-74s(o) allows licensure or certification without examination on substantially similar or higher standards.
CCB, not DPH, is the IC&RC member board.
Both credentials renew under section 19a-88 for a $195 fee.
20-74t requires at least 20 hours of continuing education each 12-month registration period, including cultural competency and veterans' mental health hours.
A state certificate, not a licence: it lets you engage in the practice of alcohol and drug counseling under 20-74s(b), but private practice is allowed only under the supervision of a licensed alcohol and drug counselor (20-74s(c)).
The state licence: its practice definition includes the clinical evaluation of substance use disorders and co-occurring disorders, including screening, assessment and diagnosis, and it is the credential for private practice without supervision (20-74s(a)(4)(A), (c)).
Chapter 376b carries both credentials: the certified alcohol and drug counselor (CADC), a state certificate, and the licensed alcohol and drug counselor (LADC), a state licence, both issued by the Department of Public Health.
The statute is practice-protected, not merely title-protected: outside its exceptions, nobody may practise alcohol and drug counseling without one or the other, and subsection (p) separately protects the titles.
The Connecticut Certification Board, a private IC&RC member board, administers the exam and issues separate CAC and AADC credentials β private certifications, not state credentials, and no substitute for either one.
The same letters mean different tiers in different states; see CADC vs LADC vs LCDC vs CAC.
βExcept as provided in subsections (s) to (x), inclusive, of this section, no person shall engage in the practice of alcohol and drug counseling unless licensed as a licensed alcohol and drug counselor pursuant to subsection (d) of this section or certified as a certified alcohol and drug counselor pursuant to subsection (e) of this section.β
The CADC requires no degree at all β only 360 hours of commissioner-approved education, of which at least 240 must relate to the knowledge and skill base of alcohol and drug counseling practice.
The LADC adds a master's degree from an accredited institution in social work, marriage and family therapy, counseling, psychology or a related field approved by the commissioner, that included at least 18 graduate semester hours in counseling or counseling-related subjects.
One historic substitution survives in the text: an applicant holding certified clinical supervisor status from the Connecticut Certification Board as of October 1, 1998 could substitute that certification for the master's and the coursework.
For which entry tiers take no degree at all, see can you be an addiction counselor without a degree?
βthree hundred sixty hours of commissioner-approved education, at least two hundred forty hours of which relates to the knowledge and skill base associated with the practice of alcohol and drug counselingβ
Both credentials rest on the same experience floor: 300 hours of supervised practical training in alcohol and drug counseling that the commissioner deems acceptable, plus three years of supervised paid work experience or unpaid internship that entailed working directly with alcohol and drug clients.
A master's degree may be substituted for one year of the three.
The statute states no hour total for the three years and no minimum hours per year; the implementing regulations were not among the sources read, so confirm with DPH how part-time work counts before you plan a timeline around it.

βcompleted three years of supervised paid work experience or unpaid internship that the commissioner deems acceptable that entailed working directly with alcohol and drug clients, except that a master's degree may be substituted for one year of such experienceβ
The statute asks for a department prescribed examination.
DPH's requirement pages name the test: verification of successful completion of the International Certification Examination for Alcohol and other Drug Abuse Counselors of the IC&RC/AODA, administered by the Connecticut Certification Board.
Once DPH finds a candidate eligible, CCB schedules the exam, which is offered four times per year; the application is online only with a $190 fee and a photograph attached.
DPH cautions that the results count for state certification and licensure and will not necessarily qualify the examinee for CCB certification β passing the exam is not the same as holding the private board's credential.
βVerification of successful completion of the International Certification Examination for Alcohol and other Drug Abuse Counselors of the International Certification & Reciprocity Consortium/Alcohol & Other Drug Abuse, Inc.β
Supervision is a defined term in 20-74s(a)(7), and the definition is demanding: regular on-site observation of the counselor's functions and activities by a licensed alcohol and drug counselor or another licensed behavioral health professional whose scope of practice includes screening, assessment, diagnosis and treatment of substance use and co-occurring disorders, including review of records, reports, treatment plans or recommendations.
What that definition means for the experience requirement is not settled by the sources read: DPH's requirement pages say the three years are as defined in Sec. 20-74s-l of the Regulations of Connecticut State Agencies, and those regulations were not among them.
Confirm with DPH how a supervisor's credentials and arrangement are evaluated before you count on a placement.
βthe regular on-site observation, by a licensed alcohol and drug counselor or other licensed behavioral health professional whose scope of practice includes the screening, assessment, diagnosis and treatment of substance use disorders and co-occurring disorders, of the functions and activities of an alcohol and drug counselor in the performance of his or her duties and responsibilities to include a review of the records, reports, treatment plans or recommendations with respect to an individual or groupβ
The statute defines LADC practice as clinical evaluation of substance use disorders and co-occurring disorders β screening, assessment and diagnosis, treatment planning, counseling, therapy, trauma-informed care and psychoeducation with individuals, families and groups.
The CADC's practice definition is narrower: professional application of methods that help individuals or groups understand dependency problems, define goals and plan action, with no diagnosis language in it.
Private practice is restricted to the LADC, or to a CADC practising under the supervision of a licensed alcohol and drug counselor, so a CADC cannot build an independent practice.

βno person shall engage in the private practice of alcohol and drug counseling unless (1) licensed as a licensed alcohol and drug counselor pursuant to subsection (d) of this section, or (2) certified as a certified alcohol and drug counselor pursuant to subsection (e) of this section and practicing under the supervision of a licensed alcohol and drug counselorβ
The commissioner may license or certify without examination an applicant who, at application, holds a credential from a governmental agency or private organization elsewhere whose standards are, in the commissioner's opinion, substantially similar to or higher than Connecticut's.
DPH operationalizes IC&RC membership: applicants certified by an IC&RC/AODA member board are deemed to have met the education, training and experience documentation, and need only arrange verification of that certification.
CCB, not DPH, is Connecticut's IC&RC member board, so the reciprocity network runs through the private board while the state credential itself still comes from DPH.
For what IC&RC reciprocity transfers, and why NAADAC credentials do not, see IC&RC vs NAADAC.
βIndividuals who are certified by a board that is a member of the IC&RC/AODA shall be deemed to have met these requirements.β
Both the licence and the certificate renew under section 19a-88 for a $195 fee.
Each registration period β defined as the twelve-month period for which the credential has been renewed and is current and valid β requires a minimum of 20 hours of continuing education, including at least one contact hour on cultural competency.
The veterans' hours run on their own clock: not less than two contact hours during the first renewal period in which continuing education is required and not less than once every six years thereafter, on mental health conditions common to veterans and family members of veterans β including determining whether a patient is a veteran or family member of a veteran, screening for conditions such as post-traumatic stress disorder, risk of suicide, depression and grief, and suicide prevention training.
The statute waives the CE requirement at the first renewal; qualifying activities include hospital-sponsored offerings, accredited institutions and courses from CCB-approved providers.
βa minimum of twenty hours of continuing education each registration periodβ
Connecticut's practice protection carries a wide exception with a hard edge.
Under (w), paid alcohol and drug counselors working under supervision sit outside the statute, as do uncompensated self-help groups including Alcoholics Anonymous and Narcotics Anonymous.
Under (s), clergy are exempt within regular or specialized ministerial duties for no separate charge, or under an established church's auspices while remaining accountable to its authority.
Under (t), licensees of seven professions β physicians and surgeons, psychologists, marital and family therapists, clinical social workers, professional counselors, APRNs and RNs β are exempt only within scope, not holding out as credentialed under this section.
Under (u), students are exempt only as supervised, designated interns or trainees in an accredited course of study. (x) applies the section to Department of Correction employees: substance abuse counselors and their supervisors hired on or after October 1, 2002 must be credentialed β earlier hires had until October 1, 2007 β apart from (u) interns and trainees and (e) supervised-paid-work-experience completers.
Two limits on this page: the 2026 Supplement and the implementing regulations were not read.
βNothing in this section shall be construed to apply to the activities and services of paid alcohol and drug counselors who are working under supervision or uncompensated alcohol and drug abuse self-help groups, including, but not limited to, Alcoholics Anonymous and Narcotics Anonymous.β
This page summarizes the Connecticut statute, rules, board pages and other documents cited above, as read for this state-by-state substance abuse counselor requirements series, current as of September 2026.
It does not list application forms, fees beyond those cited above, or processing times, and it is not a substitute for the instructions the Connecticut Department of Public Health publishes.
Nor does it cover peer specialist certification in Connecticut.
Hour totals, exams and supervision rules change by statute and by board rule; for why the same letters mean different tiers from state to state, see CADC vs LADC vs LCDC vs CAC.
Confirm every requirement with the Connecticut Department of Public Health before you count hours, register for an exam or apply β and before you take one of the substance abuse counselor jobs in Connecticut that asks for it.
For the practice of alcohol and drug counseling, yes: the statute bars practice unless you hold the LADC licence or the CADC certificate, subject to subsections (s) to (x).
The widest, (w), covers paid alcohol and drug counselors working under supervision, so some agency roles are exempt β but not at the Department of Correction, where (x) requires the credential, except (u) interns and trainees and (e) supervised-paid-work-experience completers.
Students qualify only as supervised, designated interns or trainees in an accredited course of study, and licensees of seven professions β physicians, psychologists, marital and family therapists, clinical social workers, professional counselors, APRNs, RNs β only within scope, not holding out.
Yes.
The CADC has no degree requirement: 360 hours of approved education, at least 240 of them on alcohol and drug counseling knowledge and skills, plus 300 hours of supervised practical training, three years of supervised paid work experience or unpaid internship, and the exam.
A master's degree substitutes for one year of the three.
The master's enters at the LADC, which requires one with at least 18 graduate semester hours in counseling or counseling-related subjects.
Only under supervision.
Private practice is restricted to licensed alcohol and drug counselors, or to CADCs practising under the supervision of an LADC, so a CADC cannot open an independent practice.
For that you need the LADC, which adds a master's degree with at least 18 graduate semester hours in counseling or counseling-related subjects on top of the certification requirements.
Check DPH's licensure page for the current application documents.
Connecticut handles this two ways.
The commissioner may license or certify without examination when an applicant holds a credential from a governmental agency or private organization whose standards are substantially similar to or higher than Connecticut's.
Separately, DPH deems applicants certified by an IC&RC/AODA member board to have met the education, training and experience documentation.
The Connecticut Certification Board is the IC&RC member board; the state credential comes from DPH, so apply there.
Both the licence and the certificate renew under section 19a-88 for a $195 fee.
Each twelve-month registration period requires at least 20 hours of continuing education, including at least one contact hour of cultural competency.
The two veterans' mental health hours are due during the first renewal period in which continuing education is required and at least once every six years thereafter, and the topics include identifying veteran or veteran-family patients, screening for PTSD, suicide risk, depression and grief, and suicide prevention.
The statute waives CE at the first renewal, and courses from CCB-approved providers qualify.
