Detoxing from alcohol or other substances is often the first step in addiction treatment. In fact, many people have their first-ever encounter with the treatment system through detox. And as with any first step, this stage of recovery can profoundly impact the rest of your journey.
As you plan for treatment, you may find yourself asking these questions:
Do I even need to detox?
Where do I detox?
Where can I get help planning my detox?
That’s why we’ve created this guide to drug and alcohol detox, which covers the need-to-know information.
We’ll start by examining the purpose of detox and how it fits into your recovery journey.
The U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) defines detox for substance abuse treatment as “a set of interventions aimed at managing acute intoxication and withdrawal.”1
During detox, your body withdraws from alcohol or drugs. For this reason, some medical bodies like the American Society of Addiction Management (ASAM) have actually replaced the term “detoxification” with “withdrawal management.” Alcohol withdrawal can potentially be life-threatening, so we can’t discuss detox without stressing the importance of safety.2 It’s safest to detox under medical supervision, with the support of specialized, experienced professionals.
It’s also important to note that while detox is often the first step towards sobriety, it’s not a lasting solution to changing addictive behaviors.
According to SAMHSA’s Detoxification and Substance Abuse Treatment manual, “Detoxification, in and of itself, does not constitute complete substance abuse treatment.” Additionally, it stresses that proper treatment involves “ongoing therapeutic services ultimately intended to promote recovery for substance abuse patients.”
Followed by a comprehensive treatment plan aimed at sustainable sobriety, safe detox can serve as a crucial first step towards lasting recovery.
Whether or not you need detox depends on the history of your substance use, including the length, level of use, and type of substance used.
Receiving an evaluation from a medical professional is recommended, especially if using benzodiazepines or alcohol as withdrawal from these substances can be life-threatening. You can ask your primary care doctor or psychiatrist to connect you to the right resources. Rehabs also offer over-the-phone detox assessments as part of the intake process, then a more in-depth evaluation with a clinician.
As a rule of thumb, if you notice signs of substance or alcohol abuse as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), you may want to consider getting an evaluation for detox. Some signs of substance abuse include:
Because of the physiological effects of frequent exposure to substances, it’s always recommended to consult with a medical professional before attempting to detox.3
When you consult with a medical practitioner, they’ll determine your safest detox option by performing assessments such as:
Most residential rehabs require you to be substance-free for a certain number of days before coming in. You can find out if detox is recommended for you during your initial assessment during the admissions process.
Your substance use history will affect the withdrawal experience, how long you can expect to detox, and whether or not you’ll need medication-assisted treatment (MAT).

Here’s what you can expect from detox:
A few hours after you stop using, your body begins to adjust to substances leaving your system. This adjustment process can lead to the development of withdrawal symptoms. It might sound daunting, but keep in mind that the purpose of a supervised detox is to minimize the severity of these symptoms and ensure you’re safely clearing your body of substances.
Substance withdrawal occurs in stages, which are categorized as early, peak, and late stages.4
Early Stage
Depending on the substance, this occurs 6 to 12, or up to 30 hours after you’ve stopped using. Milder symptoms like anxiety and irritability will start to show.
Peak Stage
This stage occurs 24 to 48 hours after you’ve stopped drinking, or 72 hours for opiates. Symptoms are at their worst and can include tremors, chills and vomiting. Relapse is most likely at this stage, so having a strong support system and medical supervision is advised.
Late Stage
The body is getting used to the absence of substances and withdrawal symptoms begin tailing off. If you’ve been on a medical detox, medication can be tapered down.
On average, detox takes 3 to 7 days. Opiates and benzodiazepines are known to take the longest to withdraw from and it can take up to 14 days for withdrawal symptoms to peak.
In more serious cases, your doctor might recommend medication-assisted treatment: medication combined with counseling and behavioral therapy.5
Withdrawal effects vary by substance, with some posing more dangerous side effects than others. We explore detoxing from different substances below.
Detoxing From Alcohol
Alcohol detox poses a high risk with potential for severe withdrawal side effects like delirium tremens (DT), a life-threatening side effect of alcohol withdrawal that can cause seizures.6 Delirium tremens symptoms usually show up 2 to 3 days after someone last ingested alcohol.
Detoxing From Benzodiazepines
Benzodiazepines detox carries a high risk with potential for severe withdrawal side effects. Unsupervised withdrawal from benzodiazepines can result in lethal side effects, including seizures.7
Detoxing From Opiates
Australia’s National Drug and Alcohol Research Centre published that opiate withdrawal can be lethal.8
Detoxing From Cocaine
Cocaine withdrawal is known to be more psychological than physical.
You have several options for detox, so it helps to know what each entails.
After a medical evaluation, your doctor will suggest the best course of treatment. Usually, family and friends aren’t allowed to visit during substance abuse detoxes. However, clinical staff are there to soothe your symptoms and offer round-the-clock support. They should also keep you informed of the status of your progress.
When you contact an inpatient rehab, you’ll complete an over-the-phone assessment during the intake process. This is usually followed by an in-depth evaluation with a clinician, during which they’ll recommend a detox plan. Some on-site detox centers offer counseling during detox to ease you through its discomforts. And when you’re finished detoxing, you’ll have a smoother transition into treatment.
Many rehabs don’t have in-house detox facilities, but will refer you to a detox center and help you with transfers and other necessary logistics. Admissions staff at private centers can provide an assessment and answer your questions about cost, what to expect in treatment, and your estimated length of stay. Private detox centers are fully equipped to handle everything related to detox, and some may specialize in certain types of cases.
If you have a strong support system at home and your condition doesn’t require hospitalization, you may be able to opt for outpatient detox.10 Similarly to the other options, you’ll go through an initial assessment and outline your detox plan with a health professional. You’ll then visit a hospital or clinic daily (weekdays only), either during the day or evening. Outpatient detox programs usually range from 3 to 14 days, with sessions that run from 15 to 30 minutes. However, if your detox program includes a day hospital program, your sessions may last several hours.11 Keep in mind that outpatient detox is only done under the supervision of a medical professional working at the treatment facility you’ve signed up with.
This arrangement works for people who want to keep up with work or family responsibilities while getting the addiction treatment they need.
For many people, detoxing is a crucial part of the recovery journey. Given the importance of this step, it’s best to be equipped with accurate, up-to-date information surrounding it. The good news is, our understanding of detox from substance abuse has grown tremendously. Today, a number of different detox programs are available across the globe and it’s easier than ever to find one that fits your needs. And the more you understand about how detox works and what options are available to you, the more equipped you’ll be to find a solution.
