I often encounter situations when people are not exactly unaware of the withdrawal syndrome, but they underestimate it very much. After prolonged use, the body and its systems need time to adjust to work without an agent constantly coming from outside and changing the neurochemistry of the brain. And to us, confident up to a certain point in the strength of our will and patience, it seems that we will overcome this challenge without any problems. Well, withdrawal syndrome can be very severe and unpleasant in all respects. However, for obligate changes, it does not become the main obstacle. The one that follows comes on the scene – Post-acute withdrawal syndrome (PAWS).

What is Post-Acute Withdrawal Syndrome?

What is Post-Acute Withdrawal Syndrome?

Post-acute withdrawal syndrome (PAWS) refers to a collection of symptoms that can occur after the acute phase of withdrawal from certain substances, particularly drugs or alcohol. It is a protracted withdrawal syndrome that can persist for weeks, months, or even years after the individual has stopped using the substance.

PAWS is believed to arise from the neuroadaptations that occur in the brain during chronic substance use. When a person uses drugs or alcohol over an extended period, the brain undergoes changes to compensate for the presence of the substance. These changes include alterations in neurotransmitter activity, receptor density, and overall brain circuitry.

When the person abruptly discontinues or significantly reduces their substance use, the brain needs time to readjust to the absence of the substance. This process can result in a variety of physical, psychological, and emotional symptoms, which collectively constitute PAWS.

Why do we experience PAWS in recovering?

Why do we experience PAWS in recovering?

The underlying mechanisms contributing to PAWS are not fully understood but are believed to involve several factors, including:

Neurochemical imbalances: Substance abuse disrupts the delicate balance of neurotransmitters in the brain, such as dopamine, serotonin, and gamma-aminobutyric acid (GABA). During withdrawal, these neurotransmitter systems may take time to return to their pre-substance use equilibrium, leading to mood swings, anxiety, and depression.

Receptor changes: Chronic substance use can cause alterations in the number, density, and sensitivity of neurotransmitter receptors in the brain. When substance use is abruptly discontinued, the brain needs time to restore these receptor systems to their normal state, which can contribute to various withdrawal symptoms.

Stress response dysregulation: Substance abuse can impact the brain’s stress response systems, including the hypothalamic-pituitary-adrenal (HPA) axis. During withdrawal, these systems may be dysregulated, leading to heightened stress, irritability, and emotional instability.

Cognitive changes: Prolonged substance use can affect cognitive functions such as memory, attention, and decision-making. When substances are removed, the brain needs time to repair and restore these cognitive processes, resulting in cognitive difficulties during PAWS.

It’s important to note that not everyone who recovers from substance abuse will experience PAWS, and the severity and duration can vary widely among individuals.

When does post-acute withdrawal syndrome occur?

When does post-acute withdrawal syndrome occur?

PAWS typically occurs after the acute phase of withdrawal from substances, usually following a period of sustained and heavy substance use. The exact timing and duration of PAWS can vary among individuals, depending on many factors.

The acute phase of withdrawal typically lasts for a few days to a couple of weeks, during which individuals experience immediate and intense withdrawal symptoms as the substance clears from their system. These acute symptoms can include physical discomfort, cravings, insomnia, anxiety, and mood swings.

After the acute phase, PAWS may emerge, characterized by a more protracted and milder set of symptoms that can persist for a really long time. PAWS can occur regardless of the substance, but it is commonly associated with substances that heavily impact the brain’s reward and neurotransmitter systems, such as alcohol, opioids, benzodiazepines, and stimulants.

The onset of PAWS can vary, but it often begins within a few weeks after substance cessation. However, in some cases, PAWS may emerge later, especially for substances that produce long-lasting changes in the brain. For example, PAWS related to alcohol can manifest several weeks or months after quitting, while PAWS associated with benzodiazepines may take longer to develop.

How long do PAWS symptoms usually last?

How long do PAWS symptoms usually last?

The duration of Post-Acute Withdrawal Syndrome can vary significantly among individuals. In general, PAWS symptoms can last for weeks, months, or even years, as I have already mentioned. It’s important to note that the severity and duration of PAWS can be influenced by several factors, including:

Substance abused: Different substances can have varying impacts on the brain and body, leading to differences in the duration and intensity of PAWS symptoms. For example, PAWS associated with alcohol or benzodiazepine withdrawal can last longer compared to PAWS related to marijuana or stimulant withdrawal.

Duration and intensity of substance use: Individuals who have engaged in prolonged and heavy substance use may experience more pronounced and longer-lasting PAWS symptoms compared to those with shorter or less intense substance use histories.

Individual factors: Biological, psychological, and environmental factors can also influence the duration of PAWS. Each person’s unique physiology, genetics, overall health, and stress levels can impact how long PAWS symptoms persist.

It’s important to remember that PAWS is a dynamic process, and symptoms may fluctuate in intensity and frequency over time. Initially, symptoms may be more pronounced and gradually diminish as recovery progresses. However, some individuals may experience intermittent or lingering symptoms throughout their recovery journey.

Can post-acute withdrawal syndrome be avoided?

PAWS is a natural part of the recovery process for many individuals who have experienced problems with substances. While it may not be entirely avoidable, there are strategies that can help minimize its impact and promote a smoother recovery journey. We will elaborate on the steps to alleviate and prevent the PAWS at the end of the article.

What are the most common symptoms of PAWS?

Can post-acute withdrawal syndrome be avoided?

The most common symptoms of Post-Acute Withdrawal Syndrome can vary depending on the substance abused and the individual. However, there are several commonly reported symptoms associated with PAWS:

Mood swings: Fluctuations in mood are a hallmark of PAWS. This can include periods of anxiety, irritability, depression, or emotional instability. These mood swings may be unpredictable and intense.

Sleep disturbances: Many individuals experience disrupted sleep patterns during PAWS. This can manifest as difficulty falling asleep, staying asleep, or experiencing restful sleep. Insomnia, vivid dreams, or nightmares are commonly reported.

Cognitive difficulties: PAWS can affect cognitive functions such as memory, attention, concentration, and decision-making. Individuals may experience difficulties with remembering things, staying focused, or making sound judgments.

Fatigue and low energy: Persistent fatigue, low energy levels, and feelings of lethargy are common during PAWS. Individuals may struggle with daily activities and lack motivation.

Physical discomfort: Various physical symptoms can occur during PAWS. These may include headaches, muscle tension, tremors, gastrointestinal disturbances (such as nausea or diarrhea), and general malaise.

Cravings and drug obsession: Intense cravings for the substance and preoccupation with drug-related thoughts can persist during PAWS. These cravings may come and go but can be powerful triggers for relapse if not managed effectively.

Not all individuals will experience every symptom, and the severity and duration of symptoms can vary. Additionally, individuals may experience symptoms specific to the substance they were using.

PAWS for Different Drugs

PAWS following LSD use is less common compared to other substances. However, individuals who have used LSD extensively or in high doses may experience persisting effects, sometimes referred to as hallucinogen persisting perception disorder (HPPD). Symptoms can include:

  • Visual disturbances, such as seeing trails, halos, or geometric patterns.
  • Distorted perception of time and space.
  • Emotional lability and mood changes.
  • HPPD is relatively rare, and the exact mechanisms are not well understood. If someone experiences persistent LSD-related symptoms, it is important to seek medical evaluation and support.


PAWS associated with MDMA withdrawal are less well-documented compared to other substances. However, some individuals may experience the following symptoms:

  • Mood changes, such as depression, anxiety, or irritability.
  • Sleep disturbances and fatigue.
  • Difficulty with concentration and memory.
  • MDMA affects the serotonin system, and withdrawal symptoms may be related to temporary disruptions in serotonin function. Engaging in a healthy lifestyle, including regular sleep patterns and exercise, can help support recovery.

It’s important to note that individual experiences with PAWS may vary. Substance use history, duration and intensity of use, and individual factors can influence the severity and duration of PAWS symptoms.

Managing PAWS

Managing PAWS

Post-Acute Withdrawal Syndrome treatment means start working on yourself even before the syndrome develops and involves a combination of self-care strategies, support systems, and professional guidance. Here are some detailed and structured approaches to managing PAWS:

0. Gradual tapering:

When discontinuing certain substances, such as benzodiazepines or opioids, a gradual tapering schedule under medical supervision can help reduce the severity of withdrawal symptoms, including PAWS. Slowly decreasing the dosage over time gives the brain and body a chance to adjust more gradually.

Regularly communicate with healthcare professionals, stay engaged in supportive activities, and seek professional help when needed.


PAWS Summary

Post-Acute Withdrawal Syndrome is a phenomenon that occurs during the recovery process from substance abuse. While acute withdrawal symptoms typically subside within a few weeks, PAWS can persist for a longer duration, ranging from weeks to months or even years for some individuals.

PAWS is characterized by a range of symptoms that can vary in intensity and duration. Common symptoms include mood swings, sleep disturbances, cognitive difficulties, fatigue, physical discomfort, cravings, and drug obsession. These symptoms can have a significant impact on an individual’s emotional well-being, daily functioning, and overall recovery journey.

The severity and duration of PAWS can be influenced by factors such as the substance abused, duration and intensity of substance use, individual biology, and overall health. Different substances, such as alcohol, opioids, benzodiazepines, and stimulants, can produce unique PAWS profiles.

Managing PAWS involves a comprehensive approach that may include gradual tapering, medication-assisted treatment, healthy lifestyle habits, social support, counseling or therapy, and long-term aftercare. Each person’s experience with PAWS is unique, and seeking professional guidance is essential to develop an individualized plan for managing symptoms effectively.

While PAWS can be challenging, it’s important to remember that it is a normal part of the recovery process. With proper support and treatment, individuals can navigate through PAWS, improve their overall well-being, and achieve long-term recovery from a disbalanced relationship with substances.
