States With Pending Legislation
As of March 2026, bills related to psilocybin have been introduced in over 20 state legislatures. Most propose therapeutic-only access, research authorization, or decriminalization of personal possession.
Texas approved ibogaine research funding in 2025. Virginia's governor vetoed a therapeutic authorization bill in 2025.
Frequently Asked Questions
Are mushroom supplements with "psilocybin" in the name legal?
It depends on the actual contents. Functional mushroom supplements containing lion's mane, reishi, cordyceps, and similar species are legal everywhere — even if marketing language references 'microdosing' or 'brain health.' If the product contains actual psilocybin or psilocin compounds, it's a controlled substance in most jurisdictions. Check the label and COA carefully.
Are psilocybin mushroom spores legal?
Psilocybin mushroom spores do not contain psilocybin or psilocin — the controlled substances develop only during mushroom growth. Spores are legal to possess in most states, with three exceptions: California, Georgia, and Idaho specifically prohibit spore possession. However, cultivating spores into psilocybin-producing mushrooms is illegal everywhere except Colorado (for personal use).
Can I use psilocybin for mental health treatment?
Legal therapeutic access currently exists only in Oregon (service centers), Colorado (legal personal use and developing therapeutic framework), and New Mexico (medical program launching by 2027). Clinical trials are active through Johns Hopkins, NYU, and MAPS. The FDA has granted 'breakthrough therapy' designation to psilocybin for treatment-resistant depression, but full FDA approval has not been granted.
