Substance Abuse Counselor Requirements in Maine: Credentials, Hours and Exams
Maine requires everyone who practises alcohol and drug counseling — or begins an apprenticeship — to hold a licence, certification or registration from the State Board of Alcohol and Drug Counselors, unless an exemption applies.
The ladder runs from alcohol and drug counseling aide to certified alcohol and drug counselor to licensed alcohol and drug counselor, with the certified clinical supervisor credential beside them.
The CADC is a state credential — Maine has no IC&RC counselor-level member board — and private practice belongs to the LADC alone.

At a glance
Alcohol and drug counseling aide (ADCA), certified alcohol and drug counselor (CADC), licensed alcohol and drug counselor (LADC) and certified clinical supervisor (CCS) — all issued by the state board.
State credentials from the Maine State Board of Alcohol and Drug Counselors under 32 MRSA chapter 81 and 02-384 CMR chapters 1 through 7.
The aide is called a licence in the statute but a registration in the rule chapter that implements it.
Maine has no IC&RC counselor-level member board.
Aide and CADC: a high school diploma or its equivalent (the CADC alternatively accepts board-defined course work or an associate degree in a related field).
LADC: an associate, bachelor's or master's degree in clinically based behavioral sciences or addiction counseling.
CADC aide path: a minimum of 4,000 documented hours as an aide.
LADC: 2,000 hours as a CADC, or 4,000 with an associate or bachelor's degree (2,000 with a bachelor's holding at least 18 addiction credit hours; a master's needs 2,000, or 1,500 with at least 12 credit hours).
A board-designated written examination for certification, plus the oral examination for licensure and a case presentation for the LADC.
No specific examination is named in the statute or rule.
The CADC counsels unaided but may not practise independently or privately — all work under a CCS inside an agency.
The LADC practises independently within an agency or in private practice.
Whether any tier may diagnose: Not stated in the sources read.
Professionals qualified by their own field — medicine, psychology, nursing, social work or professional counseling — need no additional certification unless they profess substance use counseling as their sole professional service (§6206(5)); academic-institution, government and program-agency employees are exempt only for activities solely within the agency or under its jurisdiction, where a licence is not a job requirement (§6206(2)).
None to transfer: Maine has no IC&RC counselor-level member board, so IC&RC reciprocity between member boards cannot move a counseling credential into Maine.
Out-of-state licensees use §6220: a discretionary waiver where the board finds standards substantially equivalent or higher, plus a separate endorsement process under Title 10, section 8003-H.
Continuing education every 2 years, odd-numbered year to odd-numbered year: aide 12, CADC 18, LADC 25, CCS 12 contact hours; LADC plus CCS 37; at least 4 in ethics for all but CCS-only licensees.
The statute expires licences annually on November 30th.
The Maine credential ladder
- Alcohol and Drug Counseling Aide(ADCA)Pre-licensure
The entry rung: an apprenticeship status at an agency under a named certified clinical supervisor, and the path through which aide hours toward the CADC are earned.
The statute defines the aide as licensed by the board (32 MRSA §§ 6203-A(2), 6213-B); rule chapter 3 titles the same status a registration.
- Certified Alcohol and Drug Counselor(CADC)Other
A state certification, not a licence: it authorizes individual or group alcohol and drug counseling unaided, but the holder may not engage in independent or private practice — all work must sit under a certified clinical supervisor within an agency (32 MRSA § 6203-A(5)).
- Licensed Alcohol and Drug Counselor(LADC)Independent
The licence: alcohol and drug counseling services independently within an agency or in private practice, with supervision duties available once the holder is also licensed as a certified clinical supervisor (32 MRSA § 6203-A(9)).
- Certified Clinical Supervisor(CCS)Supervisor
A separate credential for supervising aides and CADCs, open to certain licensed mental health professionals and to LADCs; the statute and board rule state different qualification routes for it (32 MRSA § 6214-E; 02-384 CMR ch. 6) — see the supervision section.
Four credentials under one board — and the aide goes by two names
The board issues four credentials: the alcohol and drug counseling aide, the certified alcohol and drug counselor, the licensed alcohol and drug counselor and the certified clinical supervisor.
Practice is protected across all of them, and §6205 separately protects the titles and abbreviations C.A.D.C., L.A.D.C. and A.D.C.A.
The aide carries two status words: the statute defines the aide as licensed by the board (§6203-A(2)), while rule chapter 3 is titled Registration as an Alcohol and Drug Counseling Aide.
The CADC itself is a board-issued state credential, not a private IC&RC certificate, and Maine has no IC&RC counselor-level member board to issue one.
The same letters mean different tiers in different states; see CADC vs LADC vs LCDC vs CAC.
“Unless exempted under section 6206, a person may not practice alcohol and drug counseling or begin an apprenticeship in this State unless that person has first obtained a license, certification or registration as provided in this chapter”
A high school floor for the CADC; a qualifying degree for the LADC
The aide must be at least 18, hold a high school diploma or its equivalent, be employed at an agency and have a certified clinical supervisor named (§6213-B).
The CADC builds from the same diploma: either the aide-experience path, or board-defined course work or an associate degree in behavioral sciences, addiction counseling or a related field — the rule counts an associate degree from a listed field or a minimum of 30 credit hours in listed subject areas, and deems the University of Maine at Augusta's Substance Abuse Rehabilitation Technician Certificate and the MHRT/Community certificate to meet the requirement (rule ch. 4 § 2).
The LADC requires an associate, bachelor's or master's degree in clinically based behavioral sciences or addiction counseling or a related field, plus course work defined by board rule.
For which entry tiers take no degree at all, see can you be an addiction counselor without a degree?
“At a minimum, course work as defined by board rule or an associate degree from an accredited college or university in behavioral sciences, addiction counseling or a related field as defined by board rule.”
4,000 hours on the CADC's aide path; the LADC total falls as education rises
The CADC's experience route takes a minimum of 4,000 hours of documented clinically supervised work experience as an aide, spanning at least 3 of 5 statutorily listed treatment functions — clinical evaluation, treatment planning, counseling of individuals, groups, couples or families, case management, and client and family education.
The LADC accepts three routes: 2,000 hours of documented supervised practice as a CADC; 4,000 hours with an associate or bachelor's degree in a qualifying field, cut to 2,000 for a bachelor's holder with at least 18 credit hours of course work in addiction counseling; or 2,000 hours with a master's, cut to 1,500 with at least 12 credit hours.
Course work shortens hours; it never replaces them.

“a minimum of 4,000 hours of documented clinically supervised work experience as an alcohol and drug counseling aide”
A written exam for the CADC; the LADC adds an oral exam and a case presentation
Both credentials turn on board-designated examinations: the CADC needs a passing score on the written examination for certification (rule ch. 4 § 5), while the LADC needs passing scores on that written exam and on the oral examination for licensure, supported by a case presentation that stays valid for up to 2 years after the board approves it (rule ch. 5 § 4).
Chapter 4 requires CADC passing scores within 1 year after the initial application is submitted; chapter 5 allows 2 years for LADC scores.
No specific examination is named in the statute or rule — §6216 has the board prepare the exam and lets it cooperate with any organization in preparing, administering and grading it.
“The applicant shall achieve passing scores as determined by the board on the written examination for certification and the oral examination for licensure designated by the board.”
One supervision hour per 20 client-contact hours, and the CCS beside it
The ratio is identical for the CADC's aide path and every LADC route: 1 hour of supervision for each 20 hours of direct client contact, verified by a signed affidavit.
The CCS credential is licensed by the board to provide supervision (§6203-A(6)).
The statute's CCS routes (§6214-E, PL 2019) both set 24 hours of clinical supervision training including at least 6 hours in each of four areas; its named professions — psychologist, physician, clinical nurse specialist, clinical professional counselor, clinical social worker, mental-health professional, LMFT and pastoral counselor — must also show 1,000 hours of practice under their qualifying license or co-occurring-disorders experience plus at least 3 years supervising clinicians in a licensed co-occurring program, while the LADC route names training only — no practice hours, no exam.
Rule chapter 6 (effective 2004) differs: 30 didactic hours, an exam, and LADC-route practice hours graded by degree — 4,000, 2,000 or 1,000 as an LADC.
The sources disagree on hours, exam and experience; confirm current CCS requirements with the board before counting training hours.
“1 hour of supervision for each 20 hours of direct client contact”
Agency practice under supervision for the CADC; private practice for the LADC
The CADC counsels unaided but cannot go independent: the statutory definition bars independent or private practice and puts all work under a certified clinical supervisor within an agency.
The LADC practises independently within an agency or in private practice, and may assume clinical supervision duties once also licensed as a CCS.
The aide is confined to agency work under CCS supervision and may not engage in independent or private practice.
Nothing read states whether any of these credentials may diagnose.
The exemptions have conditions: professionals in medicine, psychology, nursing, social work or professional counseling are exempt only if qualified by their profession's requirements and not professing substance use counseling as their sole professional service (§6206(5)), and academic-institution, government and program-agency employees only for activities performed solely within the agency or under its jurisdiction where a licence is not a requirement of employment (§6206(2)).
For what an addiction credential does and does not let you diagnose or bill, see can a certified addiction counselor diagnose or bill insurance?
“A certified alcohol and drug counselor may not engage in independent or private practice. All work performed must be under the supervision of a certified clinical supervisor within an agency.”
Moving to Maine: endorsement, and no IC&RC counselor bridge
Maine has no IC&RC counselor-level member board — the state's IC&RC participation covers prevention — so IC&RC reciprocity, which runs between member boards, cannot move a counseling credential into Maine.
Section 6220 has two parts.
Under (1), the board may waive chapter requirements and grant a registration, certificate or license to an applicant authorized to practise in another US jurisdiction or country whose professional standards are substantially equivalent to or higher than Maine's, as long as no cause for denial exists under §6217-B or Title 10, section 8003, subsection 5-A, paragraph A.
Under (2), the board must maintain a separate licensure-by-endorsement process under Title 10, section 8003-H, which carries no equivalence test on its face.
The provision dates from PL 2021, chapter 642.
For what IC&RC reciprocity transfers, and why NAADAC credentials do not, see IC&RC vs NAADAC.
“substantially equivalent to or higher than those set forth in this chapter”
CE every 2 years by tier — on top of an annual November 30 expiry
Board rule sets continuing professional education every 2 years, measured from one odd-numbered-year renewal to the next: 12 contact hours for aides and CCSs, 18 for CADCs and 25 for LADCs, everyone except licensees licensed solely as CCSs must include at least 4 contact hours in professional ethics, and the initial licence term is exempt (ch. 7 § 4).
The statute runs on a different clock: all licenses issued under the chapter expire annually on November 30th, with renewal due by that date and a 90-day late-renewal window (§6219).
Read together, the licence renews each year while the CE certification comes due in odd-numbered years — confirm your own cycle with the board before planning CE.
“LADCs who are also certified clinical supervisors need to complete 37 contact hours in total.”
A 2025 privacy re-enactment and a 2025 re-formatting of the CCS rule; tiers untouched
Public Law 2025, chapter 111 re-enacted §6207-B, which makes the address and telephone number of an applicant or licensee that are in the board's possession confidential.
The saved copy of rule chapter 6, the certified clinical supervisor standards in effect since November 1, 2004, carries a July 18, 2025 stamp for APAO word-format conversion and an accessibility check — a re-formatting, not an amendment.
No changes to the tiers, hour totals or examinations appear in the sources read for 2023 through 2026.

Frequently Asked Questions
Do you need a license to be a substance abuse counselor in Maine?
Yes.
Section 6207-A bars anyone from practising alcohol and drug counseling or beginning an apprenticeship without a license, certification or registration from the board, unless an exemption applies.
The aide status and the CADC cover supervised agency practice; the LADC is the credential for independent or private practice.
Professionals qualified in fields like medicine, psychology, nursing, social work and professional counseling are exempt under §6206(5) unless they profess substance use counseling as their sole professional service.
Is the Maine CADC an IC&RC credential?
No. Maine's CADC is issued by the State Board of Alcohol and Drug Counselors, and Maine has no IC&RC counselor-level member board — the state's IC&RC participation is on the prevention side — so IC&RC reciprocity cannot transfer a counseling credential into or out of Maine.
Counselors licensed elsewhere apply under 32 MRSA §6220: the board may waive its requirements for credentials it finds substantially equivalent to or higher than Maine's, and a separate endorsement process runs under Title 10, section 8003-H.
Can a certified alcohol and drug counselor open a private practice in Maine?
No. The CADC's statutory definition states that the holder may not engage in independent or private practice, and that all work must be performed under a certified clinical supervisor within an agency.
Private practice — inside an agency or out — requires the LADC.
The aide is similarly restricted to agency work under supervision.
How many supervised hours do you need to become an LADC in Maine?
It depends on the route: 2,000 hours of documented supervised practice as a CADC; or 4,000 hours with an associate or bachelor's degree in a qualifying field, reduced to 2,000 with a bachelor's plus at least 18 credit hours in addiction counseling; or 2,000 hours with a master's, reduced to 1,500 with at least 12 credit hours.
Every route also requires the written exam, and LADC applicants add the oral exam and a case presentation.
How often do Maine alcohol and drug counselors renew, and how much CE is required?
Continuing education runs every 2 years, measured from one odd-numbered-year renewal to the next: 12 contact hours for aides and CCSs, 18 for CADCs and 25 for LADCs; an LADC who is also a CCS needs 37 in total, and everyone except CCS-only licensees needs at least 4 hours in professional ethics.
The statute itself expires licenses annually on November 30th, so confirm your renewal date with the board.
