The detox symptoms timeline progresses in stages, typically worsening before improving. Generally, it lasts about a week with symptoms gradually dissapating after three days. However, the duration of the severity of symptoms can change depending on the extent of the addiction and various health factors.
Key Takeaways
- Knowing what happens during withdrawal can help clear up misunderstandings so people feel more comfortable with the detox process.
- During withdrawal, people’s bodies attempt to adjust to functioning without drugs or alcohol in their systems, causing unpleasant withdrawal symptoms. Typically, symptoms onset after a few hours, peak within 1-3 days, and dissipate within a week.
- While withdrawal symptoms are unpleasant, medications make them more manageable. Once stabilization is achieved, clients enter rehab, addressing the underlying cause of addiction.

Introduction
According to SAMHSA 2024 research, 80% of people who needed substance use disorder treatment didn’t get it. To get a handle on the big picture, 42 million people went without care.

The reasons people don’t get the help they need vary, but for many, it’s a fear of the unknown or of the detox process itself. And we’re not gonna lie. Detox is not easy. But once you understand the stages, timeline, and severity, you’ll be prepared for what’s ahead.
Moreover, one week (the typical detox timeline) is a small price to pay for getting your life back. And Encino Detox Center will guide you every step of the way, ensuring the process is as comfortable as possible.
What Happens To The Body During Detox?
Different drugs affect the body in different ways, but most drugs cause an imbalance of chemicals in your body. For example, opioids elevate the feel-good chemical dopamine, while alcohol boosts the calming neurotransmitter GABA.
With chronic use, your body adjusts to operating at these higher levels. Once the substance is taken away, it struggles to operate at normal levels, and you experience withdrawal symptoms. These vary by drug type, but often include mood swings, digestive issues, muscle pain, and flu-like symptoms.
What Does the Detox Timeline Look Like?
The detox timeline is generally divided into three stages, as follows:
- Stage 1: Early Withdrawal: Onset begins several hours after the last use with mild symptoms.
- Stage 2: Acute Withdrawal: (Typically 24-72 hours after the last use): Severe symptoms appear.
- Stage 3: Post-Acute Withdrawal Symptoms (PAWS): After severe withdrawal, symptoms will begin to dissipate over the course of the week. However, for some, symptoms can last for months or even a year, developing into PAWS. This is more likely to happen with heavy use.
What Is the Detox Timeline by Substance Use Disorder?
The detox timeline varies by substance use disorder as follows:
Alcohol Withdrawal
- Onset: 6-12 hours
- Peak: 24-72 hours
- Resolves within 5-7 days
- Alcohol Withdrawal Symptoms: Anxiety, tremors, excessive sweating, nausea, vomiting, elevated heart rate and high blood pressure, detox headache symptom, insomnia, hallucinations, risk of seizures, and delirium tremens at peak.
Opioid Withdrawal
- Onset: 8-24 hours
- Peak: 36-72 hours
- Resolves within 5-7 days
- Opioid Withdrawal Symptoms: muscle aches, goosebumps, sweating, runny nose, nausea/vomiting/diarrhea, restlessness, insomnia, intense cravings
Note: The timeline above is for short-acting opioids. With longer-acting opioids, onset may be 36-48 hours, and withdrawal may last 2-3 weeks.
Stimulant Withdrawal
- Onset: Within hours
- Peak: 1-3 days
- Resolves within a week
- Stimulant Withdrawal Symptoms: Extreme fatigue and hypersomnia, depression, irritability, increased appetite, strong cravings, cognitive fog; psychological symptoms can persist for weeks
Benzodiazepine Withdrawal
- Onset: Varies by formulation, with short-acting benzos, onset can occur within 24 hours, and long-acting benzodiazepines can take several days
- Peak: 1-4 days
- Can take several weeks of tapering before resolution
What Factors Shape the Detox Timeline?
These previous sections indicate a typical detox timeline. However, the timeline may be prolonged, and symptoms of withdrawal may be more severe, depending on the following factors:
- Consumption Habits: People who used drugs heavily over long periods of time will experience drawn-out and more severe symptoms.
- Age/Physical Health: Individuals with physical health conditions, whether age-related or not, may have a hard time overcoming symptoms due to their bodies’ compromised state.
- Mental Health Conditions: Withdrawal produces psychological effects, causing mood swings, anxiety, depression, and irritability, which can especially impact a person with pre-existing emotional disorders.
- Substance Type: Some substances have faster onsets and resolutions, while others produce prolonged withdrawal symptoms
- Biological Factors: Various biological factors can impact the detox duration. For example, people with fast metabolisms will get through withdrawal quicker than those with slow metabolisms.
What Is Withdrawal Management in the Recovery Process?

Detox isn’t pleasant, but medical professionals and addiction specialists at treatment centers manage withdrawal symptoms to make the process more tolerable. Typically, a medical detox approach is integrated.
Medical detox is necessary in managing severe alcohol withdrawal, minimizing the risk of dangerous symptoms and life-threatening complications. Medications are also often prescribed for opioid withdrawal symptoms for a more balanced approach. While there are no FDA-approved medications for stimulant withdrawal, comfort medicines may be integrated into care.
Detox vs. Rehab
It is important to note the difference between detox and rehab. After the physical symptoms of withdrawal subside with detox, clients move on to psychological care, or rehab, addressing the underlying causes of addiction. Encino Detox Center applies an evidence-based approach, teaching clients coping mechanisms so they can deal with their emotions without turning to drugs and alcohol.
While medication is necessary in some instances, it is also possible to recover with a social detox approach. With this strategy, clients overcome drug and alcohol addiction purely through therapy and holistic methods. It is cost-effective, focuses on mental well-being, and helps with long-term sobriety.

Alcohol and benzodiazepine withdrawal are associated with the most dangerous withdrawal symptoms, including seizures, hallucinations, and delirium tremens. A medically supervised approach is always recommended in management.

While detoxing at home is possible, it is not recommended, especially not for severe addictions and benzodiazepine and alcohol withdrawal. It is best to seek professional help when overcoming these substance use disorders.
