Traditional Treatment vs Psilocybin for Alcohol Use Disorder

A Guide to Compare Traditional Alcohol Use Disorder Treatments with Psilocybin

Alcohol use disorder is a pattern of problematic drinking, in which someone finds it difficult to control or stop their alcohol use, despite the harmful effects it’s causing. An estimated 400 million people worldwide, or 7% of those 15 and older, struggle with alcohol use disorder. It is the most common type of substance use disorder.

Traditional treatment for alcohol use disorder includes behavioral therapy, FDA-approved medications, rehab, and support groups – typically in combination – to achieve abstinence or reduced drinking. While traditional treatments can be highly effective for many, others may find them insufficient, or they work, but they don’t prevent relapse.

Because of the high rates of relapse, with around 70% of people relapsing after recovering from alcohol or substance use disorder, there is a need for other options.

Psilocybin for alcohol use disorder is emerging as a promising treatment, as psychedelic therapy tackles problematic alcohol and substance use in a way that may offer better protection against the risk of relapse.

In this article, we’ll be defining alcohol use disorder, describing what traditional treatment involves, and what makes psilocybin for alcohol use disorder unique, as well as the evidence in favor of it.

What is Alcohol Use Disorder?

Alcohol use disorder is a medical condition included in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The previous iteration of the DSM, the DSM-IV, included two distinct disorders: alcohol abuse and alcohol dependence, with criteria for each. The DSM-5 integrates these two disorders into a single disorder, which can be mild, moderate, or severe.

The condition involves difficulty controlling or stopping alcohol use despite its negative health, social, or work-related consequences. It is characterized by identifiable brain changes that perpetuate the cycle of problematic thinking. This includes changes in brain regions involved in motivation, memory, decision-making, impulse control, and sleep regulation. These lasting alterations also make people vulnerable to relapse.

A healthcare provider can judge whether a person suffers from alcohol use disorder by finding out if they:

• Often drink more or longer than intended
• Tried to stop or cut down on drinking, but couldn’t
• Spend a lot of time drinking or recovering from its aftereffects
• Craved drinking so much they couldn’t think of anything else
• Find that drinking gets in the way of family, home, work, or educational responsibilities
• Continue to drink even if it causes interpersonal issues
• Cut back on hobbies or activities they used to enjoy so they could drink more
• Continue to drink even if it worsens their mental or physical health
• Experience a high tolerance to alcohol, making their alcohol intake high
• Experience noticeable withdrawal symptoms when the effects wear off

What Traditional Treatment for Alcohol Use Disorder Includes

A conventional treatment plan for alcohol use disorder includes one or more of the following:

• Behavioral therapy: The most common approach is cognitive behavioral therapy (CBT). This involves working with a therapist to identify and change patterns of thought and beliefs that perpetuate alcohol use disorder.

• FDA-approved medications: These include naltrexone (Revia, Vivitrol), which blocks the pleasant effects of alcohol and reduces cravings; acamprosate (Campral), which is thought to balance chemicals affected by alcohol use disorder; and disulfiram (Antabuse), which causes severe, unpleasant reactions if alcohol is consumed, such as flushing and nausea.
• Rehab: A rehabilitation center for alcohol use disorder helps patients recover through a structured plan of medical detoxification, intensive therapy (e.g., CBT), group discussions, personalized care, and being removed from the possibility of drinking.
• Support groups: Peer-led support groups, such as Alcoholics Anonymous (AA), help people with alcohol use disorder achieve abstinence through shared experience, accountability, emotional support, and spiritual principles.

What Psilocybin-Assisted Treatment for Alcohol Use Disorder Involves

Using psilocybin for alcohol use disorder involves using this psychedelic with therapeutic intentions, such as resolving the negative past experiences, beliefs, and thought patterns that drive problematic drinking.

Poor mental health is not only a potential outcome of alcohol use disorder; it often underlies the condition. Alcohol is initially used to soothe and cope with emotional distress, even though it eventually worsens it.

Safe and effective preparation also involves screening for contraindications, learning techniques for navigating altered states, setting realistic expectations for the experience, and understanding the potential benefits and risks involved. Before psilocybin therapy, it is also essential to wean off alcohol under medical supervision, as stopping drinking abruptly can be deadly in severe cases of alcohol use disorder.

Psilocybin for alcohol use disorder typically includes psychological support, provided by one or more trained psychotherapists or facilitators who are experienced in supervising people during psychedelic experiences. These supported psilocybin sessions take place in clinical settings, healing centers, or retreats.

During the dosing session, a participant typically takes a moderate-to-high dose of psilocybin (synthetic or as mushrooms). They usually then lie down during the acute effects, with pre-selected music playing and an eye mask on to facilitate an inward experience. This process creates an inward psychedelic experience that can address the root causes of alcohol use disorder, such as healing childhood trauma.

Psilocybin for alcohol use disorder also must include post-session integration sessions with a psychotherapist or facilitator who provides psychological support, in a one-on-one or group setting. This helps people gain clarity about insights, lessons, messages, and visions relevant to their alcohol use disorder, such as its cause and how to overcome it. As a participant in one study on psilocybin for alcohol use disorder said:

“I would’ve responded to any challenge by drinking, sadness, anger, boredom, frustration, fear, pretty much anything. My answer would’ve been to drink. So, in that regard, it’s changed my reactions completely because that is no longer how I respond to strong emotions. Now I just try to process things in a healthier way. I’m trying to be more patient, trying to be calmer, trying to be more loving, trying to be more accepting.”

Traditional Treatment vs Psilocybin for Alcohol Use Disorder: Key Differences

The main differences between traditional treatment and psilocybin for alcohol use disorder can be summarized as:

• Traditional treatment does not work with altered states of consciousness.
• While traditional treatment, through the use of psychotherapy and support groups, can lead to therapeutic insights, psilocybin therapy tends to catalyze these insights, with potentially many lessons occurring during a single dosing session, which may otherwise be inaccessible within ordinary states of consciousness.
• Traditional treatment may last longer than psilocybin therapy: the former can last months or years in terms of long-term therapy or AA meetings, whereas the latter may involve a treatment plan lasting up to 12 weeks. Psilocybin therapy is a short-term, intensive option. Psilocybin retreats involve a shorter time commitment, lasting 2-8 days, depending on the number of sessions offered.
• Psilocybin differs from FDA-approved medications for alcohol use disorder in that it can repair receptor function and promote neuroplasticity, which may help restore damaged brain areas.
• The 12-step program, as part of AA, may act as a source of spirituality, meaning, and purpose for attendees through its principles. Psilocybin therapy commonly achieves the same through direct spiritual experiences. The latter have also been associated with improved clinical outcomes.
• Traditional treatment is legal worldwide, whereas psilocybin therapy is only legal in certain countries and jurisdictions.

What Current Research Says About Psilocybin for Alcohol Use Disorder

There is a growing body of scientific literature supporting the efficacy of psilocybin in treating alcohol use disorder.

Clinical Efficacy and Behavioral Outcomes of Psilocybin for Alcohol Use Disorder

Research indicates the efficacy of psilocybin in producing positive behavioral outcomes:

• A 2015 study published in the Journal of Psychopharmacology showed that psilocybin led to sustained abstinence from drinking, with intensity of psilocybin effects predicting changes to drinking, and no serious adverse events were reported.
• A 2022 study published in JAMA Psychiatry found that “psilocybin administered in combination with psychotherapy produced robust decreases in percentage of heavy drinking days over and above those produced by active placebo and psychotherapy.”
• A 2025 study published in the Journal of Psychopharmacology showed that psilocybin helped reduce heavy drinking days, drinks per day, and cravings in patients with alcohol use disorder.

How Psilocybin May Affect the Brain in Alcohol Use Disorder

Researchers have also highlighted how psilocybin-induced brain changes help drive these benefits:

• A 2021 study published in Science Advances found that psilocybin repairs glutamate receptors damaged by alcohol. Alcohol-induced damage to these receptors in the prefrontal cortex is associated with impaired executive function and cravings, so this benefit of psilocybin could help aid recovery and prevent relapse.
• A 2024 study published in Scientific Reports discovered psilocybin-induced brain changes in patients with alcohol use disorder, which, as the researchers note, are linked to “enhanced goal-directed action, improved emotional regulation, and diminished craving.”

Psychological and Emotional Changes Linked to Psilocybin for Alcohol Use Disorder

It is not just neurological changes but also shifts in self-image and emotional health that help facilitate recovery:

• A 2018 study published in Frontiers in Pharmacology highlighted reports from patients enrolled in a clinical trial of psilocybin-assisted therapy for alcohol use disorder. Authors state that patients “experienced acute and lasting alterations in their perceptions of self, in the quality of their baseline consciousness, and in their relationship with alcohol and drinking. In these cases, experiences of catharsis, forgiveness, self-compassion, and love were at least as salient as classic mystical content.”
• A separate 2018 study published in Frontiers in Pharmacology also involved reports from participants about the therapeutic changes that occurred during and after psilocybin sessions, which helped them recover from alcohol use disorder.
• A 2023 study published in Psychology of Addictive Behaviors showed that psilocybin increases self-compassion in patients with alcohol use disorder while also diminishing shame-based and self-critical thought patterns and reducing cravings.

Limitations of Current Psilocybin Research for Alcohol Use Disorder

While we should be optimistic about the direction of research so far, not all studies show that psilocybin therapy is effective in treating alcohol use disorder, although there are important caveats:

• A 2025 study published in eClinicalMedicine offers more tentative findings: “A single dose of psilocybin combined with five psychotherapy sessions may not be sufficient to reduce relapse rates and alcohol use in severely affected AUD patients following withdrawal treatment. However, given the limited sample size of our study, larger trials are needed in the future to confirm these findings.”

This study also reported more adverse events in the psilocybin group than in the placebo group. However, “adverse events” within the clinical research of psilocybin are often conflated with healthy (albeit uncomfortable) processes that are natural to psilocybin therapy, such as nausea or transient anxiety.

Taken together, the growing body of evidence suggests that psilocybin is effective at treating alcohol use disorder by reducing cravings, shame, self-criticism, and the desire to numb negative emotions through drinking. Benefits also arise from psilocybin’s ability to promote self-compassion, a healthier perception of self, and greater self-control.

What To Consider Before Exploring Treatment Options for Alcohol Use Disorder

Before exploring traditional treatment or psilocybin for alcohol use disorder, it’s crucial to establish if any safety considerations may make psychedelic use unwise. This means being aware of common psilocybin contraindications, such as a personal or family history of psychosis or bipolar disorder, high blood pressure, and the use of medications such as SSRIs and MAOI antidepressants. In some cases, traditional treatment is the safer route.

Even if psilocybin is deemed physically safe, it’s still essential to develop personal readiness for the experience, so that it’s as psychologically safe as possible. This should include an awareness of possible effects, benefits, and risks; a willingness and ability to confront difficult psychological material and emotions; and resources and support in place after the experience.

Regarding this last point, while post-session integration can help clarify many psychedelic insights, alcohol use disorder often requires continuing support in the form of psychotherapy and support groups. The risk of relapse is always possible, and so it’s important for people to continue developing and maintaining the emotional health and skills necessary for long-term recovery.

With safety and readiness in mind, psilocybin can act as a powerful catalyst in the treatment of alcohol use disorder. It helps to address the psychological and neurological roots of the condition, and gives people new perspectives on how to manage emotional difficulties without drinking.
