Editor's note: An earlier version of this story, published June 4, 2026, described the bill signing as happening that week. Governor Hochul actually signed the bill on November 21, 2025. This version has been corrected and updated.
New York's biggest rewrite of its medical cannabis law since dispensaries opened in 2016 is now fully in force. Governor Kathy Hochul signed Senate Bill S3294A on November 21, 2025. Most of it took effect on February 19, 2026, and the last piece, which needed new regulations, went live on July 22, 2026. This story covers what the law itself changed and why. For the practical side, meaning what patients, caregivers and visiting patients can do at the counter today, see our companion story on New York's new possession limits and out-of-state access.
Update: October 2026
The law is now fully in effect. On July 2, 2026, the Cannabis Control Board voted to adopt the regulations that carry it out. A Notice of Adoption ran in the July 22, 2026 New York State Register (I.D. No. OCM-12-26-00002-A), and the rules took effect that day. According to the Register notice, the Office of Cannabis Management (OCM) received 19 sets of public comments and made no changes to its March proposal.
That means the one provision that couldn't start in February, letting patients registered in other states buy in New York, is now active. OCM's medical program page listed 69,031 registered patients and 4,820 certifying practitioners as of October 1, 2026. The next things to watch are whether that number stops falling and how New York's medical dispensaries handle visiting patients.
What S3294A changed in the Cannabis Law
OCM's section-by-section summary of the amendments lays out the main changes:
- Longer certifications. A practitioner's certification now lasts up to two years instead of one, unless the practitioner sets an earlier end date (Cannabis Law §30).
- Higher possession limits. Patients and caregivers can hold either a 60-day supply or the adult-use limit in Penal Law §222.05 (three ounces of cannabis and 24 grams of concentrate), whichever is greater. In the last seven days of a 60-day period, a patient can also pick up the next period's supply (§31).
- Younger caregivers and home growers. A designated caregiver can now be 18 instead of 21 (§32). Certified patients 18 and older can grow at home for personal medical use (§41).
- Reciprocity. A new §32-a lets patients certified or registered in another U.S. state, territory or Washington, D.C. buy from New York's registered organizations if they show proof of that status and a valid government photo ID.
- No more Prescription Monitoring Program check. Practitioners no longer have to check the state's Prescription Monitoring Program (PMP) before certifying a patient, and dispensaries no longer have to check it before every sale.
Why lawmakers rewrote the medical rules
New York passed its Compassionate Care Act in 2014, and medical sales started in 2016. The 2021 Marijuana Regulation and Taxation Act (MRTA) then opened an adult-use market with looser purchase limits and many more stores. Patients drifted away. State data cited by Ganjapreneur showed 92,967 registered patients on May 1, 2025. By October 2026, OCM counted about 24,000 fewer.
Much of S3294A tries to close that gap. OCM's summary describes the new possession limits as aligning with the adult-use market. Dropping the PMP check also stops treating a cannabis certification like an opioid prescription. "This legislation reflects New York's ongoing commitment to compassion, science, access, and equity," Felicia A.B. Reid, then OCM's acting executive director, said in the agency's announcement.
How the effective dates played out
The law rolled out in stages:
- Nov. 21, 2025: Hochul signs S3294A. OCM announces it on Nov. 25.
- Feb. 19, 2026: After a 90-day wait, the provisions on certifications, possession, caregivers, home growing and the PMP take effect.
- March 2026: The board proposes conforming amendments to Part 113, the medical program regulations. They are published in the State Register on March 25, and public comment closes May 25.
- July 2, 2026: The board adopts the rules.
- July 22, 2026: The rules take effect, and reciprocity starts.
Who feels the change
Patients save money and paperwork because they need to renew less often. Families gain flexibility: a parent can now name an 18-year-old child as caregiver. Practitioners have one less step before certifying. The registered organizations that run medical dispensaries can sell more per visit and serve out-of-state patients. That matters because those companies say they are under serious financial strain, as we reported in New York's medical operators say they can't afford the millions they owe.
The federal backdrop
Federal policy changed after Hochul signed the bill. In April 2026, the Justice Department and DEA placed FDA-approved marijuana drugs, and marijuana sold under qualifying state medical licenses, in Schedule III. Adult-use cannabis stayed in Schedule I, pending a separate rescheduling hearing that opened June 29. Our explainer on medical cannabis moving to Schedule III covers that process. For New York, the timing means the state finished modernizing its medical program just as Washington began treating that kind of program differently from recreational sales.
Medical cannabis requires a practitioner's certification. Adult-use purchases are for adults 21+. This is news, not medical advice.
