Picking a Psychedelic Lawyer by the Work Each Firm Lists

Pick a psychedelic lawyer by the work. For state psilocybin licensing, look at Vicente LLP, Harris Sliwoski, McAllister Law Office, Loney Law Group and Baker Law Group. For drug development, look at Husch Blackwell, Dickinson Wright and Phillips Lytle. For ketamine clinics, look at Nelson Hardiman. For cannabis operators expanding into psychedelics, look at Rudick Law Group. At Mind Medicine Law, we read each firm's own psychedelics or psilocybin practice page and recorded what each page lists. Directories and lawyer rankings were not sources.

A firm made the list only if its own website carries a psychedelics or psilocybin practice page. One firm from earlier research is absent because its own site says it is closing. The table below lists each firm's stated focus, its offices and what it publishes about fees.

What Each Firm Says It Handles

Vicente LLP's Psychedelics & Emerging Therapies page names founding partner Joshua Kappel as a lead drafter of Colorado's NMHA. Beyond state license applications, Vicente LLP lists FDA and DEA compliance guidance, compliance for federally and state-licensed facilities, and corporate formation and financings. For IND exemptions, NDAs and current good manufacturing practice (cGMP), Vicente LLP describes a strategic alliance with a Washington, D.C. firm concentrated on FDA-regulated products.

Harris Sliwoski's psilocybin law page lists entity formation, corporate governance, intellectual property, contracts and technology agreements, licensing requirements and regulatory counsel. Harris Sliwoski lists United States offices in Denver, Los Angeles, Phoenix, Portland and Seattle, plus Barcelona, Lisbon, Madrid, Sydney and Mexico City. Its ketamine page says corporate practice of medicine rules require relationships between ketamine-providing physicians and their management services organizations to comply with state limits.

In Husch Blackwell's own words, its Psychedelics & Emerging Therapies group launched in March 2022 as "the first Am Law 100 firm to establish such a practice." The page covers research, development, commercialization and clinical practice for psilocybin, MDMA and ketamine. It also lists securities, tax, products liability, employment, immigration and litigation work. Husch Blackwell lists Kimberly I. Chew (Senior Counsel) and Karen Luong (Partner) as contacts, and its offices include Denver, Chicago, Washington, DC, Los Angeles and Austin.

McAllister Law Office has a Denver office at 4035 E 3rd Ave, and Sean McAllister is the only attorney named on its homepage. Beyond the license defense, religious-exemption, DEA and Colorado work listed above, McAllister Law Office lists general business contracts and civil litigation. A "Schedule a Free Consultation" button sits on the homepage.

Loney Law Group is a Portland, Oregon firm whose Psilocybin Law page lists criminal defense, regulatory compliance, trademarks, lease negotiations, employment agreements, and administrative reviews and appeals. Loney Law Group also lists land use, zoning and jurisdictional compliance, plus product labeling requirements. The page names no attorneys and offers a "Schedule Consultation" form with no published fee.

Nelson Hardiman says it has advised clients on ketamine for close to two decades. Its page lists ketamine clinic development, pharmacy issues for infusion, reimbursement and FDA compliance, plus guidance on psilocybin, ibogaine, ayahuasca and MDMA. Some content on Nelson Hardiman's psychedelics page is dated, including predictions written around 2022, so read it for what is current before you call.

Its homepage publishes general firm prices that are not specific to psychedelics. A Strategy Consultation costs $850 per session.

What Oregon and Colorado Licensing Adds

Oregon and Colorado each run a state license program for psilocybin businesses and the people who work in them. Oregon voters passed Ballot Measure 109 in November 2020, and it is now codified as Oregon Revised Statutes (ORS) 475A. The Oregon Health Authority licenses and regulates psilocybin manufacturing, transportation, delivery, sale and purchase.

Oregon began accepting license applications on January 2, 2023. Service centers began serving clients in summer 2023. Oregon issues five credential types: worker permits, facilitator licenses, manufacturer licenses, service center licenses and laboratory licenses.

An Oregon facilitator applicant pays a non-refundable $150 application fee and a $2,000 annual license fee, or $1,000 with the reduced fee, according to the facilitator application guide. Our Oregon facilitator certification guide covers that pathway.

Colorado's Natural Medicine Division, part of the Department of Revenue, licenses healing centers, cultivations, manufacturers, testing facilities, and their owners and employees. As of October 9, 2026, its site lists 11 standard and 35 micro healing centers, 15 standard cultivations, 8 product manufacturers and 1 testing facility. Its site also lists 128 approved owners and 206 handlers.

Vicente LLP says it prepares applications under Colorado's NMHA. A Colorado Healing Center is a licensed facility where a Facilitator provides and supervises Natural Medicine Services, and a micro-tier center stores no more than 750 milligrams of total psilocin on site. A Healing Center application must show local zoning approval and premises at least 1,000 feet from schools and child care facilities, with limited exceptions.

Every Colorado natural medicine business application also needs an Owner application for each person with an ownership interest. Vicente LLP says it prepares NMHA applications, and Loney Law Group lists zoning and permit work for its Oregon clients.

Colorado changed its rules and fees in summer 2026, according to the Natural Medicine Division site. Emergency rules for Limited Regulated Natural Medicine Sales Licenses and the current fees both took effect August 12, 2026, and the current rules took effect July 1, 2026. Vicente LLP, Loney Law Group and Baker Law Group each list compliance work.

Questions to Ask Before You Hire a Firm

Seven questions help you compare these firms before you hire one.

1. Does the firm's practice page cover your state and license type? Vicente LLP's page names Oregon, Colorado and New Mexico, while Loney Law Group's page addresses Oregon and Baker Law Group's page addresses Colorado.
2. Who at the firm will do the work? Loney Law Group's page names no attorneys, while Dickinson Wright names Scot C. Crow as its contact.
3. How is the fee set, and will there be a written fee agreement? Harris Sliwoski's contact form says no attorney-client relationship forms until you enter a written fee agreement, and that submitting the form is not a request for legal advice.
4. Are you hiring for a one-time application or for ongoing compliance? Rudick Law Group's plans carry minimums, so the Essentials Plan runs at least three months and the Premier Plan at least six months at the monthly prices listed.
5. Does the firm say it handles license defense? McAllister Law Office is the only one of the ten whose page lists defending professional licenses tied to psychedelic-assisted therapy.
6. How current is the practice page? Nelson Hardiman's page includes predictions written around 2022, and one firm from earlier research has since said it is closing.
7. Does the firm advise on federal law as well as state law? The DEA defines Schedule I drugs as having no currently accepted medical use and a high potential for abuse, and Vicente LLP and Dickinson Wright both list DEA compliance work.

Who Should Look Elsewhere

These ten firms list business, licensing, drug-development and clinic work, and three kinds of reader should start somewhere else.

A person facing a personal possession charge outside the Oregon or Colorado programs should look for a criminal defense lawyer. Loney Law Group is the only one of the ten whose page lists criminal defense, and that page is about Oregon. Your state's bar association is the place to ask for a lawyer referral.

Someone deciding whether psilocybin or ketamine treatment is right for them should talk with a clinician. Oregon clients must be 21 or older, need no prescription or referral and need not live in Oregon, and service centers set their own prices, according to the Oregon client access page. Our psilocybin guide and ketamine guide cover the treatments.

Underground facilitators and sellers should not read this list as a route to legitimacy. Oregon and Colorado each run a license program for that work, described in the licensing section above. The state-by-state legal status tool shows each state's legal status.

What Would Change This List

Four kinds of change would add or remove firms here: a closure, a removed practice page, a new practice page, or a new state program.

A closure already removed one firm. Emerge Law Group's site says most of its attorneys joined Vicente LLP effective December 15, 2025.

A firm comes off the list if its psychedelics or psilocybin practice page disappears. A firm goes on when its own site adds one, because that page is the only source we use. The order is not a ranking, so a newly published fee would update that firm's fee entry and profile while its position stays the same.

State rules can also change which firms fit a situation. Colorado's Natural Medicine Division lists rule changes effective July 1 and August 12, 2026. A new state program would add a client situation above for each firm whose page names that state.
