Ann Arbor Decriminalizes Psychedelics: What It Means for Mycology Enthusiasts and Mushroom Growers


In an unprecedented move, on September 21, 2020, the city of Ann Arbor officially joined a growing roster of U.S. cities that have decriminalized the use of naturally occurring entheogenic plants and fungi, which include psychedelic mushrooms. This decision positions Ann Arbor as the third city in the nation to pass such a resolution, following the trail blazed by cities like Oakland and Santa Cruz. For mycology enthusiasts, psychedelic activists, and mushroom growers, this development is more than just a bureaucratic shift—it's an opportunity that paves the way for exciting new explorations in the fields of mental wellness, fungi cultivation, and drug policy reform. But with all these developments come questions: What does this recent change actually mean in practical terms? Who stands to benefit, and are there still limitations to be aware of?

This article will dive deep into Ann Arbor's decriminalization, explore what this means for residents passionate about fungi, explain the restrictions in place, and discuss how this resolution reflects the broader shift toward more progressive drug policies in the U.S. Ultimately, this article seeks to shed light on the growing psychedelic renaissance and its significant cultural, spiritual, and scientific implications.

What Does Decriminalization Actually Mean in Ann Arbor?

It’s important to understand what decriminalization entails, especially in contrast with legalization. While this may seem like legal semantics, the implications are critical.

In Ann Arbor's case, decriminalization means that the possession, consumption, and cultivation of naturally occurring entheogenic substances (including psilocybin mushrooms, ayahuasca, ibogaine, and San Pedro cactus) have been designated as the lowest priority for law enforcement. What this means is that, although these substances remain illegal under state law and federal law, local authorities are instructed not to allocate resources or effort to prosecuting individuals who use or grow these substances for personal, non-commercial purposes.

Crucially, there are several caveats:

  • Commercial activities such as selling these substances remain prohibited.

  • Users cannot consume psychedelics in public spaces like schools or while operating a motor vehicle.

  • Cultivation can be done for personal use, but broader distribution or activities that involve significant public exposure are not protected.

Is It “Anything Goes” for Magic Mushrooms in Ann Arbor?

No, it isn’t. The decriminalization law acts as a form of legal leniency but doesn’t grant the same legal status as, say, recreational cannabis use in states such as Colorado or California. You cannot walk into a store and legally purchase psilocybin mushrooms, nor can you advertise them. Essentially, decriminalization in Ann Arbor serves to reduce the risk of legal repercussions for individuals who cultivate and personally use these psychedelic substances, avoiding arrest or prosecution, but without granting the kind of wide commercial freedoms associated with conventional legalization.

How Ann Arbor's Decriminalization Compares to Oakland, Santa Cruz, and Denver

Ann Arbor’s decision to decriminalize these substances places it in line with other U.S. cities that have made similar legislative strides. However, there are key differences that distinguish it from the policies in Oakland, Santa Cruz, and Denver.

  • Oakland: Oakland was the first city in the nation to pass similar legislation in June 2019, effectively making law enforcement's pursuit of crimes involving entheogenic plants and fungi the lowest priority for city police. However, Oakland’s legislation also emphasized the importance of respecting the traditional Indigenous practices associated with these substances, putting a particular focus on communal and ceremonial use.

  • Santa Cruz: Passed in January 2020, Santa Cruz’s resolution focused on the personal possession and cultivation of psychedelic mushrooms, similar to Ann Arbor’s decision. What makes Santa Cruz distinct is its emphasis on promoting education and public awareness around the risks and benefits of entheogenic substances.

  • Denver: Denver’s decriminalization is narrower in scope, focusing solely on psilocybin mushrooms. As the first U.S. city to decriminalize these mushrooms back in May 2019, Denver’s decriminalization law doesn't extend to other entheogens like San Pedro cactus or ayahuasca, which are covered under Oakland, Santa Cruz, and Ann Arbor legislation.

Each city has taken a slightly different approach to entheogen decriminalization, but the common denominator is clear: a reduced focus on criminal penalties and an increased openness to the potential therapeutic benefits of these substances. Ann Arbor’s policy fits comfortably within this spectrum but, like elsewhere, still leaves open questions about how broader state and federal law will intersect with local regulations moving forward.

A Milestone for Mushroom Enthusiasts and Growers

For mycologists (those who study fungi) and home cultivators, Ann Arbor’s new resolution presents a huge development. Put simply, the ability to grow psychedelic mushrooms in one’s own home without the looming fear of legal consequences is transformative. This change is poised to ignite a renaissance within the mycology community.

The Practical Benefits for Mushroom Growers

While the generalized cultivation of mushrooms has always been of interest to hobbyists, the ability to explore psychedelic mushrooms like Psilocybe cubensis—one of the most commonly consumed species with psychoactive effects—without legal jeopardy opens the door to experimentation in new realms. Grow kits, substrate materials, and spore syringes, which are readily available for legal cultivation of non-psychoactive mushrooms, can now also be utilized for psilocybin mushrooms for personal use.

The Role of Personal Psychedelic Cultivation

Many individuals who microdose or use psychedelic mushrooms for mental health have raised concerns about the purity and safety of formulations. The ability to grow mushrooms at home allows for greater control over the cultivation process, providing users with organic, pesticide-free alternatives to what’s available on the black market. This increased control correlates with the growing trend of self-sufficient health monitoring and the development of DIY wellness approaches.

What the Law Means for Mushroom Growers in Ann Arbor

Many local enthusiasts wonder exactly how the new law will impact their ability to grow psychedelic mushrooms. Here are the key points to keep in mind:

  1. Personal Cultivation for Individual Use: Those interested in cultivating psychedelic mushrooms for personal use can do so in their own private spaces, effectively removing the need for black-market transactions. However, growers should proceed with caution in public because although prioritization of enforcement is low, displaying psychedelic mushrooms publicly could draw unwanted attention.

  2. Commercialization Is Not Allowed: Any attempt to sell psychedelics, whether mushrooms, plants, or any other entheogen, remains a strong legal no-no. If mushrooms are given away or shared in a social context, no money or barter should be involved.

  3. No Public Use Allowed: While individuals can grow for personal consumption, public behavior remains highly regulated. This includes consuming psychedelics in schools, businesses, or other highly visible places.

Could Mushroom Cultivation Become More Popular?

Given the growing curiosity surrounding medicinal, culinary, and psychedelic fungi, this decriminalization could spark a significant increase in individuals growing their own mushrooms, for both psychoactive and non-psychoactive purposes.

The Mental Health Revolution

Psychiatric research into psychedelics demonstrates the promise these substances hold for treating depression, PTSD, mental health disorders with anxiety, and more. Even microdosing—the practice of taking small, sub-perceptual doses of psychedelic mushrooms throughout the week to enhance mood or cognition—has garnered increasing attention in wellness circles. The studies suggest that these substances may:

  • Help reduce symptoms of treatment-resistant depression.

  • Ease social anxiety and end-of-life distress in terminally ill patients.

  • Assist those with substance dependency and aid in confronting the root causes of addiction.

Given these preliminary results, Ann Arbor’s choice to decriminalize psychedelic fungi might not just inspire more local hobbyists to begin growing mushrooms—it could also lead to new research partnerships between growers, clinicians, and scientists exploring these benefits further.

Culinary and Medicinal Mushroom Growing

Additionally, even non-psychoactive varieties of mushrooms like Lion's Mane or Reishi, which are renowned for their cognitive and immune-boosting effects, could gain greater prominence as the public fascination with fungi grows. The move towards decriminalization may stimulate curiosity and education about the vast kingdom of mushrooms, encouraging people interested in wellness to learn more about mycology.

Why Teaching Mushroom Cultivation Matters More Than Ever

One of the ripple effects of psychedelic decriminalization is the increased access to mycological education. Teaching individuals not only about growing mushrooms but also about responsible usage and dosage is critical in the post-decriminalization phase. Furthermore, instructional courses on identifying and foraging for psychedelic mushrooms could become essential for ensuring public safety, given the danger of misidentifying toxic, non-psychoactive species.

Connecting With Nature Through Fungi

The ability to cultivate mushrooms—whether psychedelic or medicinal—also feeds into a broader cultural movement of reconnection with nature. This philosophy is as old as time for Indigenous peoples, who have historically used psychedelics as a sacred, holistic path to healing, spiritual insight, and mindful growth.

Many in the West are finding a path towards self-healing through these mindful engagements with nature, and Ann Arbor’s law reflects these growing communities of advocates. Once educated, mushroom enthusiasts can not only grow fungi but can also contribute to broader conversations about the eco-friendly and symbiotic relationship fungi foster with the environment.

The Role of Indigenous Wisdom in Psychedelic Plants

It’s impossible to discuss psychedelic decriminalization without paying homage to the Indigenous wisdom that has long centered entheogenic substances as sacred medicines. In fact, Ann Arbor’s resolution explicitly acknowledges these cultural roots, referencing the historic and ceremonial uses of certain natural psychedelics by Indigenous tribes.

Ayahuasca (a psychoactive brew derived from specific South American vines), for example, has been used by Indigenous shamans for centuries in healing ceremonies aimed at spiritual insight and emotional relief. Similarly, San Pedro cactus, rich in mescaline, has found its way into sacred Indigenous rituals stretching back well over a millennia.

In the process of advocating for psychedelic decriminalization or legalization, it’s vital that we approach these substances with respect and cultural sensitivity, recognizing and honoring the tradition from which modern interest emerged. Many Indigenous communities express valid concerns that corporate commercialization of psychedelics could distort the deep spiritual relationships Indigenous peoples have with these substances or worse, lead to their exploitation.

Stay Informed: The Future of Psychedelic Legalization

As the psychedelic movement gains momentum and cities like Ann Arbor issue groundbreaking resolutions, many are left wondering: What does the future hold for psychedelic substances in the U.S.?

Will Federal Legalization Follow?

We’re witnessing a grassroots movement, with more cities, states, and localities inching toward decriminalization or even legalization of substances like psilocybin. Already, cities like Washington D.C., Chicago, and Portland are considering similar moves, with Oregon being the first state to formally decriminalize all drugs in 2020. These trends make it clear that psychedelics are on political and social radars in ways they haven’t been in over half a century. However, a large padlock remains at the state and federal levels—where the Controlled Substances Act continues deeming psilocybin mushrooms a Schedule I drug, classifying it on par with heroin.

As conversations develop in other state legislatures, mushroom cultivators and enthusiasts would be wise to continue advocating for scientific rigor, policymaker education, and public health protections while remaining keenly aware of the patchwork of legal landscapes in progress.
