Psilocybin, or 'magic mushrooms,' are seeing a surge in public interest, with over 11 million adults in the U.S. using them in the past year. However, the rapid growth of the psilocybin market is outpacing the development of necessary regulations and research to understand the potential benefits and risks. Researchers aim to bridge this gap by studying real-world psilocybin use, as current clinical trials focus on isolated, synthetic psilocybin rather than the full mushroom compound.

Why it matters

The growing popularity of psilocybin mushrooms mirrors the early days of cannabis legalization, where commercialization quickly outpaced regulations to protect public health. Without sufficient research and guidelines on safe use, consumers are left to navigate an unregulated market with little information on potency, dosage, and potential harms.

The details

Psilocybin is a prodrug that is converted into psilocin, the compound responsible for the psychoactive effects. Psilocin resembles serotonin and alters brain function, including synaptic plasticity. Psilocybin mushrooms also contain other tryptamine compounds, but research is limited as federal regulations require the use of isolated, synthetic psilocybin in clinical studies. The legal status of psilocybin mushrooms varies across the U.S., with some cities and states decriminalizing or legalizing supervised use, leading to an expanding and largely unregulated market. This has resulted in increased product variety and potency, raising concerns about consumer safety as people may inadvertently ingest higher doses than intended.

  • In 2019, Denver, Colorado became the first U.S. city to decriminalize psilocybin mushrooms.
  • Over the next two years, several other U.S. cities followed suit in decriminalizing psilocybin.
  • In 2020, Oregon legalized psilocybin for supervised use in licensed settings, and Colorado did the same in 2022.

What’s next

Researchers aim to study real-world psilocybin use by having people use their own mushroom products at home and provide data through app-based surveys. Independent labs can also help by analyzing the potency of the mushroom products people are using.

The takeaway

As psilocybin mushrooms become more accessible, the lack of research and regulation poses risks to consumers who are left to navigate an unregulated market with little guidance on safe use. Bridging the gap between public enthusiasm and scientific evidence is crucial to ensure the responsible and informed use of psilocybin.
