Microdosing Legalization: The Current Landscape

Did you know? Since the start of 2025, 12+ states have introduced psychedelic-related bills. 

With huge momentum building in America, we often get asked microdosing-specific policy questions like:

• Where is microdosing legal in the U.S.?

• In which states are we seeing positive progress?

• How can I help push for microdosing legalization?

In this newsletter, we’ll answer these questions and give a snapshot of the current state of microdosing (and psychedelic) legalization.

✅ In 2020, Oregon became the first state to legalize psilocybin for therapeutic use through Measure 109.

Since then, 27 service centers have opened, with over 300 licensed facilitators, many offering both microdosing and macrodosing programs.

However, access to microdosing remains limited, as the program was designed to be a supervised care model.

Barriers to microdosing access include:

• Psilocybin use is restricted to service centers and must be supervised by a facilitator.

• Long wait times before accessing the medicine.

• The requirement to go to a clinic for any dose of psilocybin.

• Transportation requirements, such as needing a designated driver, to and from the clinic.

Given that microdosing protocols usually recommend 2-3 doses a week, these requirements make access difficult for many.

Progress is Happening: In December 2024, our advocacy successfully supported the reduction of microdosing session stay requirements, with the first visit reduced to 30 minutes, and all subsequent sessions to 15 minutes.

✅ In 2022, Colorado became the second state to legalize psilocybin for personal and therapeutic use through Proposition 122.

The 2022 voter initiative decriminalized the personal cultivation, possession, consumption, and sharing of psychedelic mushrooms as well as DMT, ibogaine, and mescaline for adults 21 years and older. This means Colorado is the only state that has decriminalized microdosing for adults.

However, a safe access model has yet to be developed. Those who want to microdose in Colorado under the personal use model need to grow their own or have it gifted to them.

Next, Colorado is in the process of approving licenses for psilocybin healing centers, with the first one set to open late Spring 2025.

Based on our work, the most recently adopted regulations in Colorado have reduced the minimum session time from 3 hours to 1 hour for low-dose psilocybin and psilocin. This is a huge win for allowing microdosing in a supervised care setting.

👀 Gaining Momentum: California

Last year, we hosted our first-ever Lobby Day in Sacramento, where our executive team met with 12 lawmakers, including Senator Scott Wiener and representatives from Gov. Newsom’s office. We left feeling optimistic about microdosing in California. 

We are currently searching for a sponsor to introduce a limited microdosing bill in California this session. Please reply to this email if you can support with connecting us to elected officials in California.
