Nevada
Psilocybin is illegal in Nevada as of 16 Aug 2026.1
- Corrected and re-checked against 2 cited sources at this review.
1. What the law is
SB 242 (2023): created the Psychedelic Medicines Working Group (study only). AB 378 (2025), the Alternative Therapy Pilot Program bill, died without passage when the 2025 session ended.1
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.

3. History
The laws behind today’s status, when each took effect, and every review since, in order.
Nevada enacts SB 242, creating the Psychedelic Medicines Working Group within the Department of Health and Human Services to study the therapeutic use of entheogens, including psilocybin. The measure authorizes study only and does not legalize or decriminalize psilocybin.
Illegal status takes effect.
The Psychedelic Medicines Working Group approves its final report, recommending that Nevada develop a future regulated access program and reduce certain penalties. The report is advisory and enacts no change in law.
AB 378, which would have established an Alternative Therapy Pilot Program permitting medically supervised psychedelic use for veterans and first responders, advances through committee but dies without final passage when the 2025 session ends.
The Legislature considers SJR 10, a non-binding resolution urging Congress to boost federal psychedelic research funding.
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.
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.

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. Psilocybin is illegal in Nevada as of 16 Aug 2026. Some laws control the compound and the fungus separately, so this record states the position for psilocybin in Nevada.
