At a Glance
Maine licenses substance abuse counselors at three levels through the Board of Alcohol and Drug Counselors: the Alcohol & Drug Counseling Aide (ADCA), the Certified Alcohol & Drug Counselor (CADC), and the Licensed Alcohol & Drug Counselor (LADC). The CADC requires supervised practice within an agency. The LADC permits independent work and private practice. Both the CADC and LADC require passing IC&RC exams and accumulating supervised experience hours.
Maine peaked at 723 drug overdose deaths in 2022, nearly all driven by opioids, before declining to 607 in 2023 and 490 in 2024, according to state data. While the trend has improved, the state’s overdose death rate remains above the national average, and demand for qualified addiction counselors across Maine, from community health centers in Portland to rural treatment programs in Aroostook County, has stayed strong. If you’re considering this path, Maine’s credentialing system is more accessible than most states. You don’t need a bachelor’s degree to get started, and there’s a clear pathway from entry-level aide to fully independent practice.
Credentialing for substance abuse counselors in Maine is overseen by the Board of Alcohol and Drug Counselors, a division of the state’s Office of Professional and Occupational Regulation (OPOR). The Board issues three credential levels, each with distinct education, experience, and exam requirements. Requirements vary considerably across neighboring New England states, so if you’re weighing options, it’s worth comparing before committing to a program.

CADC: Certified Alcohol & Drug Counselor
The Certified Alcohol & Drug Counselor credential is Maine’s mid-level license. It qualifies you to practice within an agency setting under the supervision of a Certified Clinical Supervisor (CCS) or LADC. You can’t open a private practice or work independently with a CADC, but the credential is sufficient for most treatment centers, outpatient, and community health positions.
Education Requirements
To apply for the CADC, you must meet one of the following:
- An associate degree or higher in clinically based behavioral sciences, addiction counseling, or a related field from a regionally or nationally accredited institution
- A minimum of 30 college credit hours (10 courses total) in clinically based behavioral sciences, addiction counseling, or a related field
- A full (not provisional) MHRT/C certificate from the University of Maine at Augusta or the University of Southern Maine
- 4,000 hours of licensed supervised work experience in alcohol and drug counseling services, obtained while holding a Maine Alcohol & Drug Counseling Aide (AD) license and supervised by a Maine Certified Clinical Supervisor (CCS)
All applicants must be at least 18 years old and pass a criminal background check.
Experience Requirements
CADC applicants must complete 4,000 hours of supervised work experience working directly with clients facing alcohol or drug addiction. The experience must cover at least three of the following core counseling functions: clinical evaluation, treatment planning, individual or group counseling, case management, or client and family education. All hours must be supervised by a Maine Certified Clinical Supervisor (CCS) within a licensed agency. The CADC does not permit independent or private practice. All work must be performed under supervision within an agency.
Exam
The CADC requires passing the Alcohol & Drug Counselor (ADC) Exam, administered by the International Certification and Reciprocity Consortium (IC&RC). You can now register directly with IC&RC without prior Board exam approval, a process change from earlier years. Study materials, candidate guides, and practice exams are available on the IC&RC website. You must pass the exam before submitting your full licensure application to the Board.
LADC: Licensed Alcohol & Drug Counselor
The Licensed Alcohol & Drug Counselor is Maine’s highest addiction counseling credential. Per the Board’s licensing page, the LADC authorizes providing “individual or group alcohol and drug counseling services independently within an agency or in private practice,” something the CADC does not allow. If your goal is to eventually run your own practice or take on clinical supervision duties, the LADC is your target credential. Some counselors at this level also pursue the Licensed Professional Counselor (LPC) credential to broaden their scope of practice.
Education Requirements
The LADC requires the same educational baseline as the CADC: at a minimum, an associate degree in addiction counseling or clinically based behavioral sciences from an accredited institution.
Experience Requirements
The required supervised hours depend on your credential history and degree level:
- No prior credential: 6,000 hours of licensed supervised work experience
- Associate or bachelor’s degree: 4,000 hours
- Master’s degree: 2,000 hours
- Active CADC holder: 2,000 hours
All hours must be obtained while holding a qualifying license type and supervised by a CCS licensee or, for other clinical mental health licensees, a full clinical mental health licensee or CCS.
Exam
The LADC requires passing the Advanced Alcohol & Drug Counselor (AADC) Exam, also administered through IC&RC. As with the CADC, you now register directly with IC&RC for the exam. After passing and receiving Board approval, your license is issued by email the following morning, and your status on the Board’s online portal changes from “pending” to “active.”
ADCA: Alcohol & Drug Counseling Aide
The Alcohol & Drug Counseling Aide credential is Maine’s entry point. It requires only a high school diploma or GED, no prior experience, and no IC&RC exam. The ADCA lets you begin working in an agency setting under supervision while you accumulate the hours needed for the CADC. It’s how most people enter the field in Maine without a college degree already in hand.
According to Maine statute (Title 32, Chapter 81), ADCA holders “may facilitate individual and direct group counseling or assume other facilitation duties under supervision and may supervise nonclinical activities.” They may also write treatment chart notations, provided the notations are co-signed by a Certified Clinical Supervisor. All work must be performed within a licensed agency. Independent or private practice is not permitted at this level.
Application Process
All three credentials follow the same general process. CADC and LADC applicants register directly with IC&RC for the required exam, pass it, and then submit a full licensure application to the Board. The ADCA skips the exam step entirely.
Step 1: Gather Documentation
Collect proof of education (diploma, transcripts, or degree), documentation of supervised work experience hours, and proof that you’re at least 18 years old.
Step 2: Submit Background Check
All applicants undergo a criminal background check through the state. Check the Board’s licensing and forms page for current fee amounts, as fees may change.
Step 3: Register for and Pass the IC&RC Exam (CADC and LADC only)
Register directly with IC&RC for the ADC Exam (CADC) or AADC Exam (LADC). You no longer need prior Board exam approval. This process changed from earlier requirements. Pass the exam before submitting your licensure application to the Board.
Step 4: Submit Licensure Application
Submit your completed application with all supporting documentation through the Board’s online portal. Faxed applications are not accepted. The Board asks that applicants not call to check status, as it slows processing. Once approved, your license is issued by email.
Renewal and Continuing Education
All Maine alcohol and drug counselor credentials renew annually by November 30, according to the Board’s licensing page. A $50 late fee applies if you miss the deadline. Continuing professional education (CPE) is required on a biannual cycle, every two years, measured from one odd-numbered-year renewal date to the next, with at least four hours covering professional ethics.
CPE requirements by credential level:
- ADCA: 12 contact hours per renewal cycle
- CADC: 18 contact hours per renewal cycle
- LADC: 25 contact hours per renewal cycle
- LADC + CCS: 37 contact hours per renewal cycle (combined requirement)
The Maine Board accepts NAADAC-approved distance learning courses for continuing education. However, distance learning courses are not currently accepted for initial licensure. Contact the Board for programs that satisfy initial certification requirements. Online renewal applications are available through the Board’s online portal.
Career Advancement: Certified Clinical Supervisor
Once you hold an active LADC, you can apply for the Certified Clinical Supervisor (CCS) credential. The CCS authorizes you to supervise counselors who are working toward their CADC or LADC, the same supervisory role you relied on during your own credentialing process.
Per Title 32 §6214-E and the Board’s licensing requirements, all CCS applicants must complete at least 24 hours of training in clinical supervision, including at least 6 hours in each of the following areas: skills assessment and evaluation; counselor development; management and administration; and professional responsibility.
Applicants who do not already hold an active LADC license must also accumulate 1,000 hours of licensed supervised work experience in alcohol and drug counseling services, while holding a qualifying clinical mental health license and supervised by a full clinical mental health licensee or CCS. Active LADC holders are exempt from this additional experience requirement. Counselors who hold or are pursuing a clinical social work credential may also want to review Maine social work licensure requirements, as both pathways can qualify for the CCS supervision role.
Salary and Job Outlook
According to the Bureau of Labor Statistics Occupational Outlook Handbook, substance abuse, behavioral disorder, and mental health counselors earned a national median annual wage of $59,190 as of May 2024. Employment in this occupation is projected to grow 17 percent from 2024 to 2034, much faster than the average for all occupations, with about 48,300 openings expected nationally each year over the decade.
Maine’s sustained focus on opioid response has kept demand for qualified counselors strong, particularly in rural and underserved parts of the state. Credential level matters for earnings: LADC holders, who can practice independently and serve private-pay clients, generally earn more than CADC holders working in supervised agency settings.

Frequently Asked Questions
Can I practice independently with a CADC in Maine?
No. The CADC requires ongoing clinical supervision and an active Supervision Agreement on file with the Board. You must work within a licensed agency under the oversight of a Certified Clinical Supervisor (CCS) or LADC. Independent practice, including private practice, requires the LADC credential.
How long does it take to become a CADC in Maine?
It depends on your starting point. If you pursue an associate degree, plan on 18 to 24 months of full-time study plus several months for exam preparation and application processing. If you take the 30-credit-hour route, expect 12 to 18 months. The 4,000 supervised hours can be accumulated concurrently while you’re completing an ADCA apprenticeship, which can significantly compress your timeline.
What’s the difference between the ADCA and the CADC?
The ADCA is an entry-level apprenticeship credential. It requires only a high school diploma, no exam, and lets you begin working in an agency under supervision. The CADC is a full professional credential requiring an associate degree or 30 credit hours, 4,000 hours of supervised experience, and the IC&RC ADC Exam. The ADCA is how many people begin building their hours toward the CADC.
Does Maine offer licensure by endorsement for counselors licensed in other states?
Yes. Under Maine statute (Title 32 §6220), the Board may waive licensure requirements for applicants who hold authorization to practice from another U.S. jurisdiction, provided that jurisdiction maintains professional standards substantially equivalent to Maine’s. Contact the Maine Board of Alcohol and Drug Counselors directly to inquire about endorsement eligibility, as the Board evaluates each application individually.
What are the education requirements to become an LADC?
The LADC requires at minimum an associate degree in addiction counseling or clinically based behavioral sciences from an accredited institution. The supervised experience requirement (ranging from 2,000 to 6,000 hours) depends on your degree level and whether you already hold an active CADC credential.
