How Long Does It Take for Detox to Work?

What Detox Really Means in Recovery

Detoxification is the body’s way of eliminating drugs or alcohol after a period of use. For people struggling with drug addiction or long-term alcohol use, it’s often the first step in a broader treatment plan. Detox is not a cure, but it does clear the way for meaningful addiction treatment to begin.

This process is especially important for those dealing with substance use disorders, as the body may have developed a strong physical dependence on certain substances. Safely managing drug withdrawal requires more than willpower—it often needs medical supervision.

Factors That Influence Detox Duration

The length of time to detox from drugs can vary widely from one person to the next. While timelines are important to understand, the experience is rarely predictable down to the day.

A few key factors determine how long it takes:

• The type of substance used
• Duration and frequency of use
• Age and physical health
• Co-occurring mental health conditions
• Whether a person is using medical assistance or going cold turkey

There’s no universal clock for detox. Each person’s experience depends on the complexity of their situation, their overall health, and the level of support they receive.

General Detox Times for Different Drugs

The specific drug involved plays a large role in determining how long detox might take. Below is a general outline of detox times for different drugs:

Alcohol

Withdrawal symptoms usually begin within 6 to 12 hours after the last drink. Symptoms may peak around 72 hours, with the worst effects—such as tremors, nausea, and anxiety—often improving within 5 to 7 days. Severe cases may involve hallucinations or seizures and need medical supervision.

Opioids (heroin, oxycodone)

Symptoms often start within 12 to 24 hours after the last dose. Early signs include muscle aches, sweating, and restlessness. More intense symptoms—such as vomiting, diarrhea, and cravings—may last up to 10 days, though some people feel lingering effects beyond that.

Benzodiazepines (Xanax, Ativan)

Detox from benzos tends to take longer, often beginning within a few days of stopping use and lasting 10 to 14 days or more. Symptoms can include insomnia, anxiety, muscle tension, and in some cases, seizures. This detox should always be done with medical assistance due to potential complications.

Stimulants (cocaine, methamphetamine)

Withdrawal usually begins within a few hours and can peak in 1 to 3 days. Common symptoms include fatigue, depression, and strong cravings. Most people start to feel better by day 7 to 10, but mental health symptoms like anxiety or mood swings may last longer.

Cannabis

Though often overlooked, cannabis withdrawal is real. Symptoms—such as irritability, sleep problems, and decreased appetite—typically start within 1 to 3 days and can last up to 2 weeks. For heavy, long-term users, the detox process may take even longer.

These numbers offer a general sense of the detox process, but the severity of withdrawal symptoms and the need for medical detox can stretch or shorten these timelines.

What the Detox Process Looks Like

The detox process usually unfolds in three important stages: evaluation, stabilization, and preparation for ongoing treatment. Each stage plays a vital role in helping the body and mind adjust to functioning without drugs or alcohol.

• Evaluation involves a full medical and psychological assessment. Clinicians check what substances are in the person’s system, look for any co-occurring mental health conditions, and create a personalized treatment plan based on the severity of drug use and overall health.
• Stabilization focuses on managing withdrawal symptoms, keeping the person comfortable, and reducing cravings. This may include medications, hydration, nutrition, and emotional support. Medical supervision is crucial during this phase, especially for substances with high-risk withdrawal symptoms like alcohol, opioids, or benzodiazepines.
• Preparation for treatment comes once the individual is medically stable. This stage sets the foundation for the next step in recovery, whether that’s residential care, outpatient therapy, or another form of addiction treatment.

Whether it’s detox for drug abuse or alcohol use, professional support helps make the process safer and more manageable—reducing risks and improving comfort as the body adjusts.

Risks of Cold Turkey

Some individuals attempt to quit substances abruptly without medical support—a method often called going cold turkey. While the desire to stop is commendable, doing so without guidance can lead to serious health risks.

Withdrawal from substances like alcohol or benzodiazepines can cause life-threatening complications, including seizures or cardiac issues. Even when symptoms are less severe, the emotional distress can be overwhelming. Medical detox is strongly recommended for anyone with a history of heavy or long-term use.

Does Detox Work For Drug Tests?

Detox helps remove drugs from the body, but it’s not a guaranteed way to pass a drug test—especially if the test is soon after use. Some substances stay in your system long after withdrawal symptoms fade. Detox supports recovery, not quick fixes.

Here’s how long drugs can usually be found in the body depending on the type of test:

Urine Tests

These tests check for recent drug use and are used most often.

• Marijuana: up to 30 days
• Cocaine: 2–4 days
• Heroin: 1–3 days
• Benzos: 3–7 days
• Meth: 2–5 days

Blood Tests

Blood tests show very recent use, often within hours.

• Most drugs: a few hours to 2 days
• Not used often because of short detection times

Saliva Tests

These detect recent use but not long-term drug history.

• Marijuana: 1–3 days
• Cocaine, meth, heroin: up to 2 days

Hair Tests

These tests go back months but won’t catch very recent use.

• Most drugs: up to 90 days
• Doesn’t show very recent use (1–2 days)

While detox can help your body clear substances naturally, it’s not meant to help someone pass a drug test quickly. Its real purpose is to start the recovery process in a safe and supportive way.

Importance of Medical Assistance in Detox

Professional detox programs provide a level of care that makes a real difference. With medical supervision, individuals can receive medications to ease discomfort, reduce complications, and stabilize both physical and mental health.

Medical assistance during detox is particularly important for those with co-occurring disorders or severe substance dependence. Trained staff monitor for complications, adjust care as needed, and offer the emotional support that can make detox more manageable.
