When someone stops using a substance they’ve become physically or psychologically dependent on, they may experience withdrawal. This is the body’s reaction to the absence of a drug it has grown used to. Withdrawal causes discomfort, and in some cases, it is dangerous, but it’s a necessary step toward recovery. Many people wonder, How long does withdrawal last? The answer depends on several factors, including the type of abused substance, the length and intensity of use, and the individual’s health and metabolism.

What is Withdrawal?

Withdrawal is the symptoms that occur when substance use is reduced or stopped altogether. People may experience mild to severe symptoms that vary depending on the substance involved.

Common symptoms include:

  • Anxiety or depression
  • Sweating or chills
  • Insomnia or fatigue
  • Nausea and vomiting
  • Muscle aches or tremors
  • Cravings
  • Irritability or agitation

General Withdrawal Timelines by Substance

Each situation is unique, although there are general timelines that most people typically experience.

Alcohol

  • Symptoms begin: 6–12 hours after the last drink
  • Peak: 24–72 hours
  • Duration: 5–7 days
  • Note: Severe alcohol withdrawal can lead to delirium tremens (DTs), a life-threatening condition. Medical supervision is recommended.

Opioids (e.g., heroin, oxycodone, fentanyl)

  • Symptoms begin: 8–24 hours after last use (short-acting); 24–48 hours (long-acting)
  • Peak: 2–3 days
  • Duration: 5–10 days
  • Note: Post-acute withdrawal symptoms (PAWS) such as mood swings or sleep issues can persist for weeks or months.

Benzodiazepines (e.g., Xanax, Ativan, Valium)

  • Symptoms begin: 1–4 days
  • Peak: 1–2 weeks
  • Duration: Weeks to months
  • Note: Withdrawal from benzodiazepines can be dangerous and should be done under medical supervision with a tapering plan.

Stimulants (e.g., cocaine, methamphetamine)

  • Symptoms begin: A few hours to 1 day
  • Peak: 2–4 days
  • Duration: 1–2 weeks
  • Common symptoms: Fatigue, depression, sleep issues, and increased appetite

Nicotine

  • Symptoms begin: Within a few hours
  • Peak: 2–3 days
  • Duration: 2–4 weeks
  • Common symptoms: Cravings, irritability, anxiety, and trouble concentrating

Cannabis (Marijuana)

  • Symptoms begin: 1–3 days after last use
  • Peak: 2–6 days
  • Duration: 1–2 weeks (sometimes longer for heavy users)
  • Common symptoms: Irritability, sleep disturbances, anxiety, and appetite changes

Factors That Influence Withdrawal Duration

The length and severity depend on several individual factors. The type of substance used, the length of use, and the dosage are significant factors. How the substance is consumed, for example, smoking versus injecting, impacts withdrawal when relevant.

Overall health and even metabolism play a role in withdrawal duration. Co-occurring physical or mental health conditions and even poly-substance use impact how long withdrawal can last.

Managing Withdrawal Safely

Some withdrawal symptoms can be intense or even life-threatening. It’s important to seek medical help, especially for substances like alcohol, benzodiazepines, or opioids. Options include:

  • Medical detox programs for 24/7 monitoring and symptom management
  • Medication-assisted treatment (MAT) for opioid and alcohol withdrawal
  • Outpatient support, including therapy, peer support, and monitoring
  • Hydration, nutrition, and rest help your body recover
