The screening and intake process generally takes 1-2 weeks. We recommend booking a session at least one month in advance to allow for adequate preparation.

Our mushroom are sourced from local, licensed manufacturers according to Oregon Health Authority regulations. It has been tested by a licensed laboratory to ensure purity and potency, and allows for precise dosing.

Modern clinical trials and scientific research studies use a dose range of approximately 25-40mg of mushroom active compound, and at Odyssey we use doses within this same range.¹³ We also take into consideration your intentions, preferences, and past experience (or lack thereof) when determining dose.Individuals first take an initial dose of mushrooms, and after approximately 90 minutes, a facilitator offers an optional booster dose, which is approximately one-half of the initial dose.

The optional booster dose allows for a potential deepening of the mushroom experience within a single session, according to an individual’s preference. Based on our experience, the optional booster dose greatly contributes towards maximizing the benefits of a single session.

The choice between a private or group mushroom experience depends on your intentions, preferences, and priorities.

The main advantages of a private session are more personalized, one-on-one time with a licensed facilitator, allowing for more individualized attention and support. This includes more time to connect and build trust with your facilitator before the journey, more time to work on integration with your facilitator post-journey, and receiving your facilitator’s full and unwavering attention during the journey itself. A private session may be the better option if you expect to be working through challenging psychological and emotional material during your journey, or simply would prefer more privacy and regular support.

The advantages of a group retreat include the opportunity to connect with like-minded others, to share in the experience with a sense of community, and to take time away from your ordinary surroundings in a curated retreat setting. An Odyssey retreat includes hospitality elements (accommodations, meals, concierge services) and pre- and post-mushroom journey group programming that a private session does not. While each participant’s mushroom journey on a retreat is inwardly focused, sharing the retreat experience with a group can be a unique opportunity to lean into the joyous and connective aspects of mushrooms.

Explore the benefits of mushroom with a private experience tailored to your intentions, priorities, and preferences. Modeled after entheogenic therapy protocols used in clinical trials, a private experience with Odyssey includes over 14 hours of personalized support from an expert, licensed facilitator. Schedule your session at one of our premium licensed service centers at a time convenient for you.

After you connect with a licensed facilitator, if you and your facilitator agree to work together, you’ll schedule the mushroom session at a time convenient for you.

- Private mushroom journey at a beautiful, licensed facility
- World-class screening & intake process
- Comprehensive preparation & integration program, including four hour-long preparation and integration sessions with your facilitator.

The hospitality elements of an Odyssey group retreat (accommodations, meals, concierge services) are not included in a private session. You’ll be responsible for your own accommodations, transport to and from the airport, and other necessities. We can help with transportation to/from the service center. During the intake process, we’ll share some helpful information around finding accommodations near the service center that match your preferences and budget.

Odyssey private sessions range from $3,500 - $4,500 USD, depending on the facilitator. While all of our licensed facilitators are highly vetted, rates may vary depending on a facilitator’s experience level, credentials, and specializations.

Based on what we learn about you in the screening and intake process, we’ll do our best to match you with a licensed facilitator uniquely suited to working with you. However, if after your initial conversation you don’t feel that this facilitator is a good fit, we’ll be happy to match you with another facilitator to work with instead.

An Odyssey retreat is an immersive, all-inclusive 4-day experience designed to maximize the benefits of mushroom. Enjoy the comfort and serenity of a beautiful, natural setting and rest assured knowing our team of licensed facilitators is here to support you every step of the way. While your mushroom journey will be inwardly focused, sharing the retreat experience with a group can be a unique opportunity to lean into the joyous and connective aspects of mushrooms.

In September 2023, Odyssey made history by running the first-ever legal mushroom retreat in the US.

Please see our Retreats page for upcoming retreat dates.

Odyssey retreats are four days / three nights.

An Odyssey retreat follows this schedule:

Day 1: Arrival & preparation
Day 2: Mushroom experience
Day 3: Reflection
Day 4: Integration & departure

Specifics of preparation and integration activities may vary depending on the licensed facilitators leading the retreat.

Between 8-12 participants attend each retreat.

Generally we have one licensed facilitator for every two participants for each retreat. A high facilitator:participant ratio allows for a deep level of support, even in a group setting.

In the morning of the second day of the retreat, we’ll travel as a group from the retreat center to a nearby licensed service center. The sessions are held in a spacious room, and you will be given a comfortable mattress to lay on and eye shades to wear. You’ll also be invited to bring any other items you may want to be comfortable during the journey (a journal, meaningful personal item or token, water bottle, etc.)

Odyssey’s licensed facilitators are present for the full duration of the session, and retreat guests are never left alone during their experience. If you ever need support during the journey, a facilitator will be there to help you. Facilitators take a non-directive approach, not trying to “guide” your experience but fluidly adapting to your needs as they arise.Music is played over a speaker in the room.

The playlists we use consist of mostly instrumental music and are curated to deepen and enhance the entheogenic experience. Participants are encouraged to focus on their own inner experience, and to allow others the space to do the same. We ask that participants not interact with one another during the session. Everyone is in the same physical space, having their own private journey.

This combination of laying down with music, eye shades, and focusing inward with non-directive support is the format used research studies at Johns Hopkins, Imperial College London, NYU, and other institutions. See our Science page for more on how Odyssey’s session format draws on scientific research protocols.

Our retreats include one mushroom session, done on the second day of the retreat.

Odyssey retreats range from $3,500 - $6,500 USD for one participant, depending on choice of accommodation. Primarily private room accommodations are available, with a few shared rooms.

Mushroom experiences can vary widely between individuals, and the specifics of any particular experience are often unpredictable. However, there are commonalities across most experiences.

You may experience visual effects, color saturation, and solid objects may appear as if they’re moving or breathing. You may experience physical sensations differently, feel hot or cold, feel parts of your body in a different way or feel parts of your body you’ve never felt before. Your sense of time may become distorted, and it may seem to become compressed or expanded throughout the journey.

You may experience strong emotions – positive and negative – and you may experience two or more seemingly contradictory emotions at the same time. You may experience a deep and healing emotional release.You may see, imagine or remember people in your life, past and present, in particular those you have close relationships with.

You may confront and work through personal issues or past traumas. You may visit archetypal realms featuring figures, symbols or imagery from various cultures and mythological traditions. You may be visited by animals, or you may yourself transform into an animal.You may have the experience of everything as divine or holy, or of the alternate reality you perceive as being somehow “more real” than normal waking reality. You may lose your sense of being a separate self, and feel yourself dissolve into the universe or the cosmos. You may have a sense of deep interconnectedness and unity.

These are only some of the many possible aspects of a entheogenic journey. An experience can be overwhelming, and it can be underwhelming. Upon consuming mushrooms, your experience may not be what you expect at all. Consensus among researchers, practitioners, and the broader community is that it’s beneficial to enter a journey with openness, and let go of expectations or desires for a specific experience or outcome.

Mushroom offers a range of potential benefits that can profoundly impact our mental and emotional well-being. It can provide us with insights into our core beliefs and sense of identity, and help us break out of negative patterns and habits. It can facilitate deep healing through emotional release. It can help us process and work through personal challenges and past traumas. It can lead to greater self compassion, and increased compassion for others, leading to better relationships.

Mushroom has been shown to induce profound mystical-type experiences, often rated by study participants as among the most spiritually significant and personally meaningful of their lives.^1,2,3 These experiences involve a dissolving of our normal sense of self and a sense of vast interconnectedness with all that exists. This can lead to an inner sense of renewal and revitalization, and a new, deepened appreciation for everyday life.

Mushrooms, when administered with psychological support, has demonstrated great potential in the treatment of major depressive disorder and treatment resistant depression.^4,5,6 Mushrooms has also been shown to reduce depression and anxiety in cancer patients.^7,8 Mushrooms may also hold promise for the treatment of smoking addiction and alcohol dependence.^9,10,11,12

An entheogen experience has much in common with embarking on a journey. There’s an initial call, away from the comfortable and familiar and towards the unknown. It may require courage to follow the call. Although what lies ahead cannot be known, it will likely be filled with a great variety of fantastic new sights, deep emotions, intense sensations, and novel experiences.

A mushroom journey unfolds over several hours (although it can sometimes feel like much more, or much less) and there’s often a sense of traveling through phases: embarkation, escalation or “come-up”, peak, de-escalation or “come-down”, and finally a return to normal waking consciousness. By the end you may feel like you’ve lived a lifetime in a single day. The result can be a glorious return to the present, returning “home” to the familiar world, transformed in both obvious and subtle ways.

Odyssey doesn’t attempt or claim to treat any medical or mental health condition. While it’s common for people to have therapeutic experiences with mushrooms, an Odyssey experience is not a substitute for medical services, psychotherapy, or any other form of treatment.

At the same time, our protocols are based on best practices used in clinical trials and research studies. In particular for our private sessions, the experience is similar to that of the entheogenic therapy process used in clinical trials.

We encourage viewing a mushroom experience as part of an ongoing process, and not a “quick fix” or “silver bullet”. While certain research has shown significant, lasting benefits from a single session, it’s impossible to predict the exact outcome of a particular entheogenic experience for any individual.<sup>5

‍</sup>Ideally, a mushroom experience takes place in the context of broader psychological and emotional work. This may include psychotherapy, which we recommend engaging in before and after your experience. It may also include practices such as meditation or journaling, which have been shown in research to support personal work with entheogens.¹⁸

Certain research has shown significant, lasting benefits from a single mushroom session.⁵ Our experience matches this, and we’ve found that it’s common for individuals to receive substantial psychological and emotional benefits from a single mushroom session. Immediately following the experience, these individuals often don’t feel like they need (or even would like) another strong entheongen experience for some time. However, it’s impossible to predict the exact outcome of a particular experience for any individual.

After their first experience, many people find it helpful to undergo a entheogenic experience once every few months, or a few times a year, as each session often provides something new and useful. Others find more, or less, frequent experiences are best for them. For some, a single session may provide so much that they don’t feel a need to do another.

Whether once a month, year, or decade - what feels right is up to you. In general, we recommend engaging in a thorough integration process following a msuhroom session, before planning another session.

It depends what you’re looking for. Advantages of a mushroom session with Odyssey include professional guidance from licensed facilitators, curated preparation and integration support, a licensed service center setting designed for entheogenic experiences, and legality under Oregon’s state-level framework.Some individuals are comfortable taking mushroom alone, but this can pose greater risk.

The experience is likely to be more unpredictable and may lead to unforeseen, potentially severe challenges. A survey study of over 600 lifetime entheogen users found that factors such as lack of preparation, interactions with contraindicated prescription medications, lack of psychological support, and negative physical setting were associated with challenging experiences.<sup>17

‍</sup>Our view is that a mushroom experience can be one of the most transformative and meaningful experiences of an individual’s life, and should not be taken lightly. Many find that accessing mushroom services with professional support helps ensure the safest, most beneficial experience possible, and is more than worth the cost.

Safety is our highest priority. Stanford and Harvard-trained psychiatrists helped design our screening process and review applications. Our team follows the latest developments in entheogens science, and updates our screening and intake processes based on the published literature.

The mushroom is generally safe and well-tolerated, especially when administered in a controlled setting with professional supervision.¹⁴ Researchers in the UK deemed mushrooms to be safer than alcohol, tobacco, cannabis, and over a dozen other substances.¹⁵Certain prescription medications and supplements may interact with mushrooms.<sup>19

‍</sup> Most of these interactions are not dangerous, however they may impact the experience in other ways (e.g. diminishing or blunting mushroom's  effects). Potential interactions with prescription medications and supplements are addressed in detail in our screening and intake process. Mushrooms can moderately increase heart rate and blood pressure.²⁰ Individuals with a history of serious cardiac conditions or unmanaged high blood pressure should exercise caution. These potential risks are addressed in detail in our screening and intake process.

A strong entheogen experience may exacerbate or trigger the onset of certain psychiatric disorders, such as schizophrenia.²⁰ Individuals with a personal or family history of these conditions should exercise caution. These potential risks are addressed in detail in our screening and intake process.The greatest risk that a mushroom experience poses for most people is that it may uncover psychological and emotional material that needs to be processed, which can lead to challenging experiences during the processing period.²¹

Through preparation, journey, and integration with support from licensed facilitators, Odyssey group retreats and private sessions are designed to provide the support needed for anyone to work through these challenges.

Intense emotions such as sadness, anger, and fear can be and often are a part of a experience. Commonly, challenges experienced during the journey are later viewed as positive, and ultimately felt to have been necessary or worthwhile.In one study analyzing over 200 challenging entheogenic experiences, more than 67% of respondents regarded the long-term consequences of their experience to be either positive or mostly positive, while less than 4% regarded the consequences to be either negative or mostly negative.<sup>16

‍</sup>Challenging experiences are also much less likely to occur when intentional preparation, integration, “set and setting”, professional support, and other considerations are taken into account. A survey study of over 600 lifetime entheogen users found that factors such as lack of preparation, interactions with contraindicated prescription medications, lack of psychological support, and negative physical setting were associated with challenging experiences.<sup>17

‍</sup>When you book a group retreat or private session with Odyssey, we’ll send you a comprehensive package of resources to help prepare you for the journey. On a group retreat, you’ll participate in programming to further support this process. In a private session, you’ll have two hour long preparation calls with your facilitator before the journey. In both cases, your session will take place in a licensed service center designed for entheongenic experiences, with supervision from Odyssey’s highly vetted licensed facilitators.Although rare, some individuals do encounter challenges that endure beyond the session.

We’re committed to supporting you in working through whatever arises, even if that means extending additional services and support to you, at no additional cost.We take every measure to ensure each individual’s experience is safe, comfortable, and positive in both the short and long term. However, mushroom experiences are not for everyone. Our screening and intake process is professionally designed to help us and you determine if a journey with Odyssey is a good fit for you.

We recommend Michael Pollan’s bestseller How to Change Your Mind for a well-researched, approachable introduction to entheogen science, or the Netflix series of the same name (episode 2 focuses on mushrooms). During an exploratory call or anytime throughout your experience with Odyssey, our team will also be happy to answer any questions you have.
