Addiction Counselor Credentials Compared: CADC vs. CDCA vs. CASAC vs. LCDC
- by Everett Wolf
If you’ve searched for “certified addiction counselor certification” and landed in a sea of acronyms, you’re not alone. CADC. CDCA. CASAC. LCDC. CSAC. Each one is a legitimate credential, but they are not interchangeable. They belong to different states, different credentialing bodies, and different education thresholds. Trying to hold all of them in your head at once leads to confusion and wasted research time.
This post is not a deep dive into each credential. Those guides exist separately. This is the decision tool that points you to the right one for your situation.

The Alphabet Soup: Why Counselors Get Confused
The credentialing landscape in addiction counseling is fragmented by design. Each state controls its own workforce requirements, which means two neighboring states may use completely different acronyms for similar roles. Add in the national credentialing bodies, IC&RC and NAADAC, and you get a layered system where one credential may satisfy requirements in 30 states while another is accepted only in one.
Three things cause most of the confusion:
- State-specific credentials (CDCA in Ohio, LCDC in Texas, CASAC in New York, CADC (formerly CSAC) in North Carolina) are issued by each state’s board and are not portable without a separate reciprocity application.
- Multi-state credentials (CADC through IC&RC member boards) are designed with reciprocity built in. They travel more easily.
- Similar names, different bodies. NAADAC issues the NCAC I and NCAC II. IC&RC issues the ADC (Alcohol and Drug Counselor). State boards may call their credential a “CADC,” a “CASAC,” or something else entirely, sometimes using IC&RC exams, sometimes not.
The fastest way to cut through the noise is to start with geography.
The First Question: What State Will You Practice In?
Your practice state determines everything. Some states have one dominant certification pathway. Others accept multiple credentials. A few require a state-issued license rather than a certification. Before researching requirements, confirm that the credential you’re eyeing is accepted in your target state.
| State | Primary Certification | Issuing Body |
|---|---|---|
| Ohio | CDCA (Chemical Dependency Counselor Assistant) | Ohio Chemical Dependency Professionals Board (OCDP) |
| Texas | LCDC (Licensed Chemical Dependency Counselor) | Texas Health and Human Services Commission (HHSC) |
| New York | CASAC (Credentialed Alcoholism and Substance Abuse Counselor) | New York Office of Addiction Services and Supports (OASAS) |
| North Carolina | CADC (Certified Substance Abuse Counselor) | NC Substance Abuse Professional Practice Board (NCSAPPB) |
| Most other states | CADC (Certified Alcohol and Drug Counselor) | IC&RC member board for that state |
If your state is not on this list, look for your state’s IC&RC member board at internationalcredentialing.org/icrc-credentials/. Most states use an IC&RC-affiliated ADC or CADC credential as the primary entry point.
At-a-Glance Comparison: Four Major Credentials
| Credential | State / Body | What the Name Means | Minimum Education Hours |
|---|---|---|---|
| CADC | Multi-state via IC&RC member boards | Certified Alcohol and Drug Counselor | Varies by board (often 270+ education hours) |
| CDCA | Ohio (OCDP) | Chemical Dependency Counselor Assistant | 40 hours (Preliminary phase); 30 hours additional (Renewable phase) |
| CASAC | New York (OASAS) | Credentialed Alcoholism and Substance Abuse Counselor | 350 education hours (CASAC-T path) |
| LCDC | Texas (HHSC) | Licensed Chemical Dependency Counselor | 270 education hours |
| CADC | North Carolina (NCSAPPB) | Certified Alcohol and Drug Counselor (formerly CSAC: Certified Substance Abuse Counselor, renamed Jan 1, 2020) | 270 education hours |
Two important notes on reading this table. First, “education hours” refers to pre-credential training completed before you apply for the credential. This is not CE. These are required education hours completed upfront as part of initial qualification. Second, supervised practice hours are a separate requirement on top of the education hours. Every credential listed above also requires hundreds or thousands of supervised work hours. The table above shows only the education-hour component.
NAADAC offers its own credential track through the National Certification Commission for Addiction Professionals (NCC AP), which issues the NCAC I, NCAC II, and the Master Addiction Counselor (MAC). These are national credentials with their own eligibility tracks and are accepted in some states as a primary credential or as a reciprocity pathway.
When Each Credential Travels: Reciprocity Logic
If you are licensed in one state and move to another, portability matters. Here is the core distinction:
IC&RC credentials (CADC and equivalents) are built for reciprocity. IC&RC maintains member boards across the U.S. and internationally. A counselor who earns an IC&RC ADC credential through one member board can often transfer to another member board in a new state through a streamlined reciprocity process rather than starting over. The exam is the same; the supervised hours still count.
State-specific credentials (CDCA, CASAC, LCDC, CSAC) require state-level reciprocity applications, and the outcome depends on whether the receiving state’s board accepts the sending state’s credential. Texas and Ohio, for example, have their own evaluation processes. A Texas LCDC moving to Ohio may apply for reciprocity but will go through OCDP’s review, not an automatic transfer.
If you plan to practice in multiple states or move frequently, an IC&RC-based credential gives you the most flexibility. If you will practice only in Ohio, Texas, New York, or North Carolina, the state-specific credential is often the faster and cheaper first step because you do not need to meet any higher multi-state minimums.
One more reciprocity note: some states that do not have a robust state-specific credential still operate through IC&RC but use the name “CADC” for the IC&RC ADC. Others use the name “LADC” (Licensed Alcohol and Drug Counselor) or “LCADC.” The underlying exam and competency framework are the same. If you encounter an acronym not listed here, check whether the issuing board is an IC&RC member board before assuming it is a completely separate system.
Picking by Education Level
Your highest completed degree can narrow the decision quickly. Some credentials require a bachelor’s or master’s degree. Others are accessible with a high school diploma and supervised experience. Here is a practical guide:
High school diploma or GED:
- Ohio CDCA (Preliminary phase requires 40 education hours, no degree required)
- CADC-I through many IC&RC boards (no degree required; education hours and supervised hours carry the weight)
Associate’s degree:
- CASAC-T in New York (an associate’s degree in a behavioral health field qualifies, alongside 350 education hours)
- CADC-I in most IC&RC boards
Bachelor’s degree:
- LCDC in Texas (a higher degree — bachelor’s or master’s — satisfies the LCDC academic prerequisite but does NOT substitute for the 270 chemical-dependency-specific education hours, which all candidates must complete)
- CASAC in New York (full credential, shorter education-hour path available for bachelor’s holders)
- CADC in North Carolina (bachelor’s required for the standard pathway)
- CADC-II in many IC&RC boards
Master’s degree:
- Qualifies for expedited or advanced tracks in most credentials listed above
- Required for the MAC (Master Addiction Counselor) through NAADAC’s NCC AP
If you hold a bachelor’s or master’s in counseling, social work, or psychology, you likely qualify for multiple credentials simultaneously. The deciding factor returns to your state of practice.
Once You’ve Decided: Where to Go Next
Each credential has its own application, exam, supervision, and renewal requirements. The summaries above are starting points. For the full picture on each, use the guides below:
- CADC (multi-state): Full requirements, cost breakdown, exam structure, and application steps are in the CADC certification requirements guide.
- CDCA (Ohio): Ohio-specific education phases, OCDP application process, and the 2026 education requirement changes are covered in the CDCA certification in Ohio guide.
- CASAC (New York): OASAS pathways, the CASAC-T to CASAC progression, and supervised hour requirements are detailed in the CASAC certification in New York guide.
- LCDC (Texas): TCB education requirements, the 4,000 supervised hours requirement, and the IC&RC ADC exam are covered in the LCDC certification in Texas guide.
- CADC (North Carolina): NCSAPPB requirements, the 270 education hours, and the 6,000 supervised hours are detailed in the CADC certification in North Carolina guide.
If you need a step-by-step overview of the general process from education hours to exam to credentialed status, the step-by-step guide to getting your drug and alcohol counselor certification walks through the full sequence without credential-specific detours.
Once you have your credential in hand, CE becomes your ongoing responsibility. Each credential above requires CE hours at renewal, and the approved providers differ by credential and state. CEU Matrix is approved across all major credentialing bodies, including NAADAC Provider #6310, NBCC Provider #94564, and IC&RC approved, as well as state-specific approvals for Ohio (OCDP #50-19236), Texas (TCB #1758-07), and North Carolina (NCSAPPB). NAADAC-credentialed counselors can browse the NAADAC-approved course library; IC&RC-credentialed counselors will find matching content in the IC&RC-approved catalog. When your credential renewal comes due, CEU Matrix covers the CE requirement regardless of which credential you hold.
Start with your state. Match your education level. Then go read the credential guide that applies to you.
