Since the start of the psychedelics boom, several U.S. cities have passed various legislation to decriminalize psychedelic drugs. However, don’t confuse this with meaning that these are now technically legal psychedelics.

These measures do not allow for the legal and indiscriminate use of psychedelics. Rather, they offer protection to individuals engaging in practices with psychedelics at home, or for spiritual or therapeutic purposes without commercial intent.

The Difference Between Legalization And Decriminalization

Most psychedelics continue to be Schedule 1 substances under U.S. federal law. This means the term “legal psychedelics” in the U.S. is a bit confusing.

With the exception of ketamine, a controlled substance, most psychedelic drugs continue to be illegal in the United States.

These include the following substances.

• Psilocybin (present in magic mushrooms)
• LSD (acid)
• DMT (the active compound in ayahuasca)
• Mescaline (present in the peyote cacti)
• MDMA, also known as ecstasy or molly, among others

The federal government makes it illegal to produce, buy, possess, or distribute these substances.

However, the U.S. system also allows for certain “sanctuary cities,” to exist. In other words, this is the removal of criminal penalties for the use of psychedelics. It effectively allows for personal use and possession of small amounts of “entheogens” These are plants and fungi that naturally produce psychedelic substances — so, sure, can be referred to as “legal psychedelics.”

In general, these resolutions don’t allow for the development of a large-scale market around the use of psychedelic substances. Use and possession still need to occur in non-commercial contexts to enjoy decriminalization privileges. These often come with at-home use or within small private groups.

Oregon

For the time being, Oregon is the only jurisdiction where psychedelics enjoy decriminalization at the state level. This does not mean these drugs are all legal psychedelics. The use of psychedelics in the state fall under two categories, depending on the substance. Psilocybin is the only one falling into a special category.

In November of 2020, Oregon voters approved Measure 110, also known as the Drug Addiction Treatment and Recovery Act. This removed criminal penalties on the use and possession of all drugs, including psychedelics. The measure made the personal possession of small amounts of drugs a civil violation with a $100 fine. The fine may drop if a person enlists in one of the state’s Addiction and Recovery Centers.

The adoption of Measure 100 is to reduce the use of hard drugs like heroin and cocaine. However, its language also removes tough penalties on the personal use of psychedelic substances.

On the same November ballot, Oregonians approved Measure 109. This establishes a state-licensed psilocybin-assisted therapy system: the first in the country. The ballot set up a two-year development period — currently ongoing — directing the Oregon Health Authority (OHA) to license and regulate the manufacturing, transportation, delivery, sale and purchase of psilocybin products. Likewise, OHA is responsible for supervising the creation of licensed facilities for the delivery of psilocybin treatment.

The development period will end on December 31, 2022, so for now, access to medical treatment psilocybin in Oregon continues to exist informally, falling under the umbrella of Measure 110.

Legal Psychedelics In California: Oakland and Santa Cruz

In California, two cities have passed local reform decriminalizing the personal use of naturally-produced psychedelics.

The Oakland City Council now says that no city funds or resources are available to impose criminal penalties on the use and possession of entheogenic plants by adults. These include psilocybin mushrooms, the peyote cacti, the iboga shrub and the concoction known as ayahuasca.

The resolution declared the planting, cultivating, purchasing, transporting, distributing, using and possessing entheogenic plants or plant compounds among the lowest law enforcement priority and directed the District Attorney to cease prosecution of persons involved in the use of entheogenic plants.

In 2020, Santa Cruz followed suit, passing a similar resolution resolving that the city cannot use resources in the investigation and arrest of persons 21 and older for the personal use, possession, or cultivation of entheogenic plants and fungi.

Legal Psychedelics In Washington State: Seattle

Washington State enjoys reduced penalties on the possession of all drugs, with special decriminalization measures happening in Seattle for psychedelics.

Since July 2021, a senate bill approved in Washington reduces penalties for the possession of any drug from a felony to a misdemeanor. The law will be active for a period of two years, and it encourages law enforcement officers and prosecutors to derive first and second-time offenders charged with possession of drugs to drug treatment rather than arrest.

In October 2021, Seattle became the largest city in the country to decriminalize natural psychedelics. It makes the investigation, arrest, and prosecution of entheogen-related activities among the city’s lowest enforcement priorities.

Approval from the city of Port Townsend, a small jurisdiction across the lake from Seattle, completed a similar resolution in December 2021.

Legal Psychedelics In Colorado: Denver

In May 2019, Denver became the first city in the country to impose decriminalization measures on any psychedelic compound. In Denver, personal possession of psilocybin-producing mushrooms is now the “lowest law enforcement priority.”

This prevents the use of any funds for law enforcement on the personal use and possession of psilocybin mushrooms by adults.

Legal Psychedelics In Michigan: Detroit And Ann Arbor

Michigan houses three jurisdictions where the decriminalization of psychedelic substances exists.

In 2020, the City Council of Ann Arbor resolved that planting, cultivating, purchasing, transporting, distributing, engaging in practices with, or possessing entheogenic plants or their derived schedule 1 compounds are the lowest law enforcement priority within the city.

According to the resolution:

• No use of city funds or resources for any investigation, detention, arrest, or prosecution of people who use entheogenic plants.
• It also mandates the District Attorney to “cease prosecution of persons involved in the use of Entheogenic Plants or plant-based compounds.”

In January of 2021, Washtenaw County — where Ann Arbor is — extended a similar policy to the entire county. However, driving under the influence of psychedelic compounds continues to be a crime liable to prosecution.

Later that same year, Detroit became the second largest U.S. city — after Seattle — to decriminalize psychedelics. Detroit voters approved a ballot decriminalizing the personal possession and therapeutic use of entheogenic plants by adults. It now means doing so is the city’s lowest law-enforcement priority.

Sale and distribution of psychedelics continues to be criminalized. Still, the Detroit Police Department (DPD) must cease using resources to investigate and prosecute Detroit residents for personal possession. Likewise, the DPD must do so for therapeutic use of these substances as well.

Washington DC

The nation’s capital is one of a few U.S. cities where decriminalization of the non-commercial use of psychedelics exists.

In November 2020, residents in Washington DC approved an initiative making the investigation and arrest of persons 18 years of age or older among the Metropolitan Police Department’s “lowest enforcement priorities.”

This is true for the following when discussing entheogenic plants and fungi.

• Non-commercial planting
• Cultivating
• Purchasing
• Transporting
• Distributing
• Engaging in practices with or possessing

Massachusetts: Boston Suburbs

Psychedelic substances continue to be criminalized in the city of Boston — again, this doesn’t make them legal psychedelics. However, residents of the city are within walking distance from two jurisdictions where the non-commercial use of psychedelics is decriminalized.

The City Councils of Somerville and Cambridge are both part of the Boston Metro Area. These cities decriminalized entheogenic plants and fungi in early 2021. However, the agreement states no use of city funds or resources in the enforcement of criminal penalties . This includes the use and possession of entheogenic plants by adults.

The investigation and arrest of adults for planting, cultivating, purchasing, transporting, distributing, engaging in practices with, or possessing entheogenic plants is amongst the lowest law enforcement priority. The District Attorney must cease prosecution of persons involved in the use, possession, or distribution of these substances.

Also in 2021, Northampton and Easthampton, both located about 100 miles west from Boston, took on similar resolutions. Each effectively now allow the personal use and possession of natural psychedelic substances.

The Legal Psychedelic Landscape in Mid-2026: What Has Changed

This article’s title references 2024 — but the legal landscape for psychedelics has moved faster than the publication cycle can capture. This update covers the state of U.S. psychedelic law as of June 30, 2026, including significant new regulatory frameworks, federal signals, and one development that would have been unthinkable when this article was first published: LSD moving toward FDA approval as a prescription drug.

Oregon and Colorado: regulated access is now real. Oregon’s Measure 109, which Oregon voters passed in 2020, created the nation’s first legal supervised psilocybin service framework. Psilocybin service centers began opening in 2023, and as of mid-2026, more than 300 facilitators have been licensed through the Oregon Health Authority. Sessions typically cost $500–$2,500 and require no medical diagnosis — Oregon’s framework positions psilocybin as a wellness and healing service rather than a medical treatment. Colorado’s Proposition 122 (the Natural Medicine Health Act, passed November 2022) is the nation’s broadest state psychedelic legislation: it legalized personal possession of psilocybin, DMT, ibogaine, and mescaline (not peyote) statewide as of December 2022, and created a regulated “healing center” framework that began operating in 2024. Colorado’s list of covered substances is meaningfully broader than Oregon’s — ibogaine and DMT are explicitly included. Session costs in Colorado healing centers run similarly to Oregon at $500–$2,500.

LSD is now moving toward FDA approval as a prescription medicine. Perhaps the most significant legal development since 2024: Delix Therapeutics’ DT120 (an LSD analog with modified pharmacology) reported positive Phase 3 trial results for Major Depressive Disorder in June 2026. This marks the first positive Phase 3 data for an LSD-derived compound in a large randomized trial. If DT120 achieves FDA approval, it would be rescheduled from Schedule I to Schedule II or lower — making it a legal prescription drug available through licensed prescribers. This follows the broader pattern of psychedelics entering the prescription drug pipeline: Spravato (esketamine/ketamine) was approved in 2019, and psilocybin via Compass Pathways is advancing through a rolling NDA process with FDA approval potentially in 2027. The April 2026 executive order, which designated psilocybin, MDMA, and ibogaine as national research priorities for veteran PTSD and TBI, further accelerated federal research investment and DEA scheduling review for these compounds.

City decriminalization and the federal picture. City-level psychedelic decriminalization continues to expand beyond the early movers (Denver decriminalized psilocybin in 2019; Oakland decriminalized a broad range of entheogens in 2019). Santa Cruz, Ann Arbor, Washington D.C., Seattle, Portland, and San Francisco have all passed various decrim measures for psilocybin or broader entheogen categories, with varying scope and enforcement implications. Critically, decriminalization at the city level does not mean “legal” — it means local law enforcement has deprioritized prosecution, and federal law remains unchanged. Federal law continues to classify psilocybin, LSD, MDMA, DMT, mescaline, and ibogaine as Schedule I substances. The April 2026 executive order does not change scheduling but signals a meaningful federal policy shift toward research access and potential rescheduling following FDA approval. Ketamine remains the only psychedelic-adjacent substance that is fully legal (Schedule III) and widely clinically available — IV ketamine off-label and Spravato FDA-approved for depression.

Frequently Asked Questions

Is psilocybin legal in the United States?

Psilocybin remains a Schedule I controlled substance under federal law — it is not legal at the federal level. However, state and local law creates meaningful access in limited contexts. In Oregon, supervised psilocybin service centers operate legally under Oregon Health Authority oversight; sessions are legal for any adult, no diagnosis required, but must occur at a licensed service center with a licensed facilitator. In Colorado, personal possession of psilocybin and psilocybin mushrooms is legal statewide for adults, and regulated healing centers offering supervised psilocybin experiences opened in 2024. In multiple cities (Denver, Oakland, Santa Cruz, Ann Arbor, Washington D.C., Seattle, Portland, San Francisco, and others), local ordinances have decriminalized psilocybin — but decrim is not the same as legal; it means police have been directed to deprioritize enforcement, not that possession or use is lawful. For the overwhelming majority of U.S. residents, psilocybin access outside of Oregon and Colorado service centers or legal possession in Oregon/Colorado remains a federal criminal offense, regardless of local decrim measures.

What states have decriminalized psychedelics?

As of mid-2026, the clearest state-level changes are Oregon (legal supervised psilocybin service centers under M109, operational since 2023) and Colorado (personal possession of psilocybin, DMT, ibogaine, and mescaline legal statewide since December 2022, healing centers open 2024). Beyond those two states, psychedelic decriminalization has largely occurred at the city rather than state level. Cities with notable entheogen decriminalization measures include: Denver, CO (psilocybin, 2019); Oakland, CA and Santa Cruz, CA (broad entheogens including psilocybin, DMT, iboga/ibogaine, 2019); Ann Arbor, MI (2020); Washington D.C. (Initiative 81, 2020, broad entheogen decrim); Seattle, WA (psilocybin and other plant medicines, 2021); Portland, OR (city decrim alongside Oregon state framework); San Francisco, CA (entheogen decrim, 2022). Massachusetts, Vermont, and several other states have introduced but not yet passed statewide decrim or access legislation. None of these city measures create legal markets — only Oregon and Colorado have done that.

Is LSD becoming legal as a medicine?

LSD is moving through clinical trials as a pharmaceutical candidate — and as of June 2026, it has cleared the largest scientific hurdle. Delix Therapeutics’ DT120 (a pharmacologically modified LSD analog) reported positive Phase 3 trial results for Major Depressive Disorder in June 2026 — the first LSD-class compound to achieve this milestone. If DT120 achieves FDA approval (which would require FDA review, a PDUFA date, and potential scheduling by the DEA), it would likely be rescheduled from Schedule I to Schedule II or lower, making it a legal prescription drug available through licensed psychiatrists and prescribers. This would be the first Schedule I psychedelic ever rescheduled to a prescription drug status. The timeline from positive Phase 3 to FDA approval typically runs 1–2 years. Recreational LSD remains Schedule I and would not be affected by DT120’s approval — that approval would cover the specific Delix compound under its approved indication, not LSD broadly.

Can you legally access psychedelic therapy in the US right now?

Yes — in several specific forms. The clearest legal pathways as of mid-2026: (1) Oregon psilocybin service centers — legal for any adult; supervised sessions with licensed facilitators; $500–$2,500; no diagnosis required; search the Oregon Health Authority facilitator directory. (2) Colorado healing centers — legal for Colorado residents and visitors; supervised psilocybin (and broader substance list) sessions; operational since 2024. (3) Ketamine clinics — IV ketamine is off-label but completely legal (Schedule III); 700+ clinics operating nationwide; $400–$800/infusion. (4) Spravato (esketamine) — FDA-approved for TRD and suicidal ideation; administered at licensed mental health providers and infusion centers; insurance-covered with prior auth for qualifying diagnoses. (5) Clinical trials — psilocybin, MDMA, ibogaine, and LSD-class compounds are all in active trials; clinicaltrials.gov lists recruiting studies; participation is typically free and provides medically supervised access. These are the legitimate legal pathways; underground or decrim-jurisdiction use is a separate category with a different legal risk profile.
