Chemically Dependent Anonymous
Chemically Dependent Anonymous (CDA) is a free, anonymous 12-step fellowship that treats alcohol and all other mind-altering drugs as the same problem — welcoming anyone who wants to stop, whatever their substance.
Battling addiction & ready for help?
What Is Chemically Dependent Anonymous?
Chemically Dependent Anonymous (CDA) is a free, anonymous 12-step fellowship for people recovering from chemical dependency on any mind-altering substance. Its founding idea is simple and freeing: a chemical is a chemical. CDA makes no distinction between street drugs, alcohol, and misused medication, because all of them alter the mind and all of them can take a life over. Whatever you’ve been using, if it has a hold on you, you belong.
CDA grew out of the same soil as Alcoholics Anonymous and built its program on AA’s 12 steps and 12 traditions. It started around 1980 in Maryland and now meets both in person and online, with no dues, no paperwork, and no one turned away. The only requirement for membership is a desire to stop using mind-altering chemicals.
This guide covers what CDA is, how it works, what the evidence says about 12-step recovery, and how to find a meeting, often as soon as today.
Using and not safe to stop on your own, or in crisis? Get medically safe first, then CDA is there for the long haul.
- If you use alcohol, opioids, or benzodiazepines heavily, don’t quit cold turkey. Withdrawal from these can be dangerous, even life-threatening. A medical detox is the safe way to start, and it pairs with CDA rather than replacing it. Call SAMHSA at 1-800-662-HELP (4357) any time for free, confidential help finding one.
- If you’re having thoughts of suicide or self-harm, call or text 988 now.
- CDA meetings are free and anonymous. You don’t have to be clean, or certain, to join, today.
- CDA makes no distinction between drugs, alcohol, and misused medication, so if a chemical has a hold on you, you belong, whatever you’ve been using.
- The only requirement for membership is a desire to stop using.
- It’s built on AA’s program, the 12 steps and 12 traditions, worked with a sponsor, with free and anonymous meetings in person and over Zoom.
- The model is evidence-aligned: 12-step fellowships rank with professional therapy like CBT for staying abstinent[1].
What CDA Is
CDA is a peer fellowship, not a treatment program and not a business. Its purpose, stated plainly, is to stay clean and to help others find recovery. There are no professionals running the rooms and no one to bill. People who’ve been through chemical dependency themselves carry the message to people still in it, the same one-addict-helping-another engine that powers AA and Narcotics Anonymous.
What sets CDA apart is its unifying view of what addiction actually is. Rather than sort people by their drug of choice, CDA treats chemical dependency as one condition with many faces. Street drugs, alcohol, and unnecessary medication all count as mind-altering chemicals, and recovery is about freedom from all of them, not from a single substance. For someone whose use crossed back and forth between, say, drinking and pills, that single front door can be a relief.
How Chemically Dependent Anonymous Works
Like its sister fellowships, CDA runs on two things working together: a program of action (the steps) and a community (the meetings and the people in them).
The 12 Steps and the “All Chemicals” Approach
CDA uses the 12 steps and 12 traditions adapted from Alcoholics Anonymous, and openly credits AA as the source. The steps move a person from admitting they can’t control their use on willpower alone, through self-examination and making amends, to helping others still using.
The defining twist is the “all chemicals” lens. CDA’s First Step is about powerlessness over mind-altering chemicals as a whole, not over one named drug. That’s why people recovering from very different substances work the same program side by side.
Sponsorship, Meetings, and Anonymity
Three things hold the community together:
- A sponsor — someone further along in recovery who guides newcomers through the steps one to one.
- Meetings — held in person and over Zoom, where members share experience and support.
- Anonymity — first names only, and what’s said in the room stays in the room.
That privacy is what makes the rooms safe enough for the kind of plain talk recovery asks for. Because meetings are free and open, there’s nothing to sign and nothing to pay. You can simply show up.
Does Chemically Dependent Anonymous Work?
CDA itself hasn’t been studied much on its own, but it runs on the same 12-step model as AA and NA, and that model has solid evidence behind it.
A 2020 Cochrane review found that getting people engaged in 12-step programs is as effective as, or more effective than, treatments like cognitive behavioral therapy for keeping people abstinent, with benefits that last for years[1]. That research is strongest for alcohol and AA, and CDA applies the same peer-support approach across every mind-altering chemical.
More broadly, taking part in mutual-aid groups is linked to better recovery outcomes, including abstinence, for people coming off drug use[2]. A free, peer-led fellowship is a serious form of support, not a fallback.
CDA was built on the belief that the substance doesn’t matter, the dependency does. Where some fellowships organize around a single drug, CDA puts everyone, drinkers, pill users, people who used several things at once, in the same room as equals. That shared identity is part of why it works: recovery gets rebuilt alongside people who genuinely understand, without anyone having to decide which “kind” of addict they are first.
How CDA Compares to NA and AA
CDA, Narcotics Anonymous, and Alcoholics Anonymous are close cousins built on the same 12-step foundation. The differences come down to scope and language.
| Chemically Dependent Anonymous | Narcotics Anonymous | Alcoholics Anonymous | |
|---|---|---|---|
| Focus | any mind-altering chemical | any drug | alcohol specifically |
| View of substances | drugs, alcohol, and misused meds are all chemicals | makes no distinction between drugs | centered on drinking |
| First Step | powerless over mind-altering chemicals | powerless over “addiction” | powerless over alcohol |
| Requirement | a desire to stop using chemicals | a desire to stop using | a desire to stop drinking |
| Cost | free | free | free |
In practice, the three overlap a lot, and plenty of people attend more than one. CDA’s “all chemicals” framing tends to suit people whose use spanned both drugs and alcohol and who don’t want to split their recovery across rooms. Someone recovering mainly from drugs may feel most at home in Narcotics Anonymous, and someone recovering mainly from alcohol often starts with Alcoholics Anonymous, though every one of these fellowships welcomes anyone with the desire to stop.
How to Find a CDA Meeting and Get Started
Getting started is low-stakes. Meetings are free, you can stay quiet, and you can leave if it isn’t for you. You don’t need a referral, insurance, or any clean time to walk in, just the willingness to stop using. CDA’s official website lists in-person and online (Zoom) meetings, so you can find one to join from anywhere.
If you use alcohol, opioids, or benzodiazepines, the safest first step is a medical detox, which runs right alongside the fellowship rather than replacing it. Talk to a doctor or call SAMHSA at 1-800-662-HELP (4357) to find one. Withdrawal handled with medical support is far gentler than the ordeal most people fear, and it clears the way to start the steps. If you’re in crisis or having thoughts of self-harm, call or text 988.

Frequently asked questions
What is Chemically Dependent Anonymous?
Chemically Dependent Anonymous (CDA) is a free, anonymous 12-step fellowship for people recovering from dependency on any mind-altering substance. Its founding idea is that a chemical is a chemical, so it makes no distinction between street drugs, alcohol, and misused medication. CDA is built on the 12 steps and 12 traditions adapted from Alcoholics Anonymous and meets both in person and online.
What is the only requirement to join CDA?
The only requirement for membership is a desire to stop using mind-altering chemicals. There are no dues or fees, no paperwork, and no referral needed. You don’t have to be clean already, or even sure you’re ready, to attend a meeting, and you can stay quiet and just listen.
How is CDA different from NA and AA?
All three are 12-step fellowships built on the same foundation. Alcoholics Anonymous focuses on alcohol and Narcotics Anonymous focuses on drugs, while CDA treats drugs, alcohol, and misused medication as one category, mind-altering chemicals. That “all chemicals” framing tends to suit people whose use spanned both drugs and alcohol and who don’t want to split their recovery across separate rooms.
Does CDA cost anything?
No. CDA meetings are free. Like other 12-step fellowships, it is self-supporting through its own members’ voluntary contributions and is not a business or a treatment program. There is nothing to pay and no insurance to file, you can simply show up to an in-person or online meeting.
Does the 12-step approach actually work?
The 12-step model has strong evidence behind it. A 2020 Cochrane review found that engaging people in 12-step programs is as effective as, or more effective than, treatments like cognitive behavioral therapy for staying abstinent, with benefits lasting years[1]. CDA itself is studied less than AA, but it applies the same peer-support program across every mind-altering chemical.
Is it safe to stop using before my first meeting?
Not always on your own. Withdrawal from alcohol, opioids, or benzodiazepines can be dangerous and sometimes life-threatening, so don’t quit cold turkey to “get ready” for a meeting. A medical detox is the safe way to stop, and it pairs with CDA rather than replacing it. Call SAMHSA at 1-800-662-HELP (4357) for free, confidential help, and if you’re in crisis, call or text 988.
