Weed was legalized in New York on March 31, 2021, when the MRTA became law. The Legislature passed the bill on March 30, 2021, and Governor Cuomo signed it the next day.
The law legalized adult-use cannabis for people 21 and older, rewrote the criminal penalties in Penal Law Article 222, and created the Office of Cannabis Management and the Cannabis Control Board to license and regulate the market.
Possession and personal use were lawful right away. Nothing needed to open first, which is why the signing date is the one most people mean when they ask when marijuana was legalized in New York.

Was weed decriminalized before it was legal?
Yes. Decriminalization and legalization are different steps, and New York took the first one decades before the second. The 1977 law and the 2019 law cut penalties but still treated possession as a violation, usually with a fine.
Legalization in 2021 went further. It removed the fine for lawful amounts, allowed licensed sales and made adult use a legal activity rather than a tolerated one.
When did weed become legal in New York for medical use?
Medical use came first. The Compassionate Care Act of 2014 let certified patients with qualifying conditions use cannabis products. The MRTA later folded the medical program into the Cannabis Law, and adults 21 and older no longer need a medical card to buy at a licensed adult-use store.
What can adults legally have today?
Adults 21 and older can carry up to 3 ounces of cannabis flower and 24 grams of concentrate. At home, Penal Law § 222.15 allows up to 5 pounds, which is how the law treats home-grown harvests. Selling without a license is still illegal.
| Item | Limit for adults 21+ |
|---|---|
| Cannabis flower, on you | 3 ounces |
| Concentrate, on you | 24 grams |
| Plants at home | 3 mature and 3 immature per person, 6 and 6 per household |
| Cannabis stored at home | Up to 5 pounds |
Did the 2021 law clear old marijuana convictions?
Yes. The MRTA provided for expungement of past convictions for conduct that is now legal, along with resentencing for some people. An expunged record generally cannot be used against you for housing, student loans or jobs.
What is still not legal now that weed is legal in New York?
- Possession or use by anyone under 21 (certified medical patients follow separate rules).
- Selling cannabis without a license, with civil and criminal penalties depending on the amount.
- Using cannabis in a motor vehicle on a public highway under
Vehicle and Traffic Law § 1227. - Smoking or vaping cannabis anywhere tobacco smoking is banned.
- Possession on federal property or in federally funded housing, because federal law still applies.
New York City note: The city follows the same state timeline. Possession became legal in all five boroughs on March 31, 2021. City smoke-free rules and housing restrictions still limit where you can use it.
How does New York compare with nearby states?
