1. What the law is
Nevada commissioned advice and then left it there. SB 242 (2023) created a Psychedelic Medicines Working Group, whose December 2024 report recommended a future regulated access program, and nothing has been enacted since. AB 378 (2025) would have opened a supervised psychedelic therapy pilot for veterans and first responders; it died when the 2025 session ended. Possession is a crime statewide and psilocybin is Schedule I.
Psilocybin is illegal in Nevada. It is classified as a Schedule I controlled substance under the state's controlled-substances code (NRS Chapter 453), and unauthorized possession is a criminal offense statewide under NRS 453.336. Nevada has enacted no law authorizing the medical, therapeutic, or recreational use of psilocybin, and no decriminalization measure is in effect.
Nevada has studied, but not authorized, psilocybin. In 2023 the Legislature enacted SB 242, which created the Psychedelic Medicines Working Group within the Department of Health and Human Services to study the therapeutic use of entheogens, including psilocybin, during the 2023-2024 interim. That working group approved a final report on December 13, 2024 recommending that the state develop a future regulated access program and reconsider penalties; the report is a recommendation only and changed no law. In the 2025 session, AB 378 proposed an Alternative Therapy Pilot Program that would have permitted medically supervised use of psilocybin and other psychedelics for veterans and first responders with certain conditions; the bill advanced through committee but died without passage when the session ended. A separate 2025 measure, SJR 10, was a non-binding resolution urging Congress to increase federal psychedelic research funding. Because neither the working group's report nor any 2025 bill created legal access, psilocybin remains illegal in Nevada now, and the biennial Legislature does not reconvene in regular session until 2027.
2. Trials in Nevada
Interventional psilocybin trials with at least one site in Nevada, as their sponsors filed them with ClinicalTrials.gov, EU CTIS and ISRCTN. Each row links to the registry record, which sets out who may take part.
Recruiting or opening counts trials recruiting now, not yet recruiting, or enrolling by invitation. Closed counts trials terminated, suspended, withdrawn or left unverified by their sponsors.

5. Common questions
Is psilocybin legal in Nevada?
No. Psilocybin is a Schedule I controlled substance under Nevada's controlled-substances code (NRS Chapter 453), and possession is a criminal offense statewide under NRS 453.336. Nevada has enacted no law authorizing its use.
Did SB 242 legalize psilocybin in Nevada?
No. SB 242 (2023) created the Psychedelic Medicines Working Group to study the therapeutic use of entheogens during the 2023-2024 interim. It authorized a study only and did not legalize, decriminalize, or create any access to psilocybin.
What happened to Nevada's AB 378 psychedelic therapy bill?
AB 378 (2025) would have created an Alternative Therapy Pilot Program allowing medically supervised psychedelic use for veterans and first responders. It advanced through committee but died without passage when the 2025 session ended, so no pilot program was created.
Is psilocybin decriminalized anywhere in Nevada?
No. Nevada has not enacted any statewide or local measure decriminalizing psilocybin. Possession remains a criminal offense under NRS 453.336, and the Working Group's December 2024 recommendation to reduce penalties has not been adopted into law.
Could psilocybin become legal in Nevada soon?
The Psychedelic Medicines Working Group recommended a future regulated access program in its December 2024 report, but that recommendation is advisory and no enabling law has passed. Nevada's Legislature meets biennially and does not reconvene in regular session until 2027, so no legislation is pending as of June 2026.
Are magic mushrooms ("shrooms") legal in Nevada?
"Magic mushrooms" and "shrooms" are common names for fungi that contain psilocybin, and this entry states the law on psilocybin itself, which some laws treat separately from the fungus. Psilocybin is illegal in Nevada.

Nevada's entry was checked again on 16 August 2026. The state health department's own page confirms the 2023 working group is a study body. The legislature's website could not be reached, so the bill history is queued for a manual check.
Nevada had been recorded as mixed on the strength of a working group that only studies the question. With the AB 378 pilot dead at the end of the 2025 session, nothing enacted opens access, so the status moved to illegal.
