Quick answer for Long Island
Yes — adult-use cannabis is legal in New York, including on Long Island, for adults 21 and older, under the Marijuana Regulation and Taxation Act (MRTA) and rules from the Office of Cannabis Management (OCM).
You can buy from licensed dispensaries (like Top Grass in Bellport), possess limited amounts, and — if you follow the rules — grow a small number of plants at a private residence. Public consumption is restricted, driving high is illegal, and buying from unlicensed shops is not protected under state law.
Who can buy
- Age: 21+ for adult-use purchase and possession.
- ID: Valid physical government-issued photo ID. Digital/photo-of-ID is generally not enough at licensed counters.
- Medical card: Not required for adult-use.
- Out-of-state adults: Licensed retailers typically accept valid out-of-state government IDs when they clearly show you are 21+ — bring the physical card.
Possession limits (the numbers people actually search)
Per OCM / NY Penal Law Article 222 guidance for adults 21+:
| Situation | Limit (current guidance) |
|---|---|
| On your person (carrying) | Up to 3 ounces of cannabis flower and up to 24 grams of concentrated cannabis (edibles, oil, etc.) |
| At a private residence | Up to 5 pounds of cannabis flower (or OCM-defined concentrate equivalent) |
Going over those limits can bring penalties under Article 222. Always re-check cannabis.ny.gov — this page is a snapshot, not a statute book.
Buying at a licensed dispensary
Retailers post allowable purchase limits. In practice, the state possession ceiling (3 oz flower / 24 g concentrate) is the outer edge of what a shop may sell in a transaction; a store can set a lower cap. Inventory systems enforce it at checkout.

Where you can (and can’t) consume
OCM’s public guidance: adults 21+ may consume in a private home or in most places tobacco smoking is allowed, with important carve-outs. You generally cannot consume in:
- Motor vehicles (driver or passenger)
- Businesses, restaurants (including patios), hookah/cigar bars
- Federal property, including public housing
- Most public and state parks and beaches
Landlords, co-ops, and condos may restrict smoking/vaping inside a unit even when possession is otherwise legal. When in doubt, treat “public” as a no.
Driving and transporting purchases
Do not drive impaired by cannabis. OCM states you can be charged with a DUI. Passengers also may not consume in a vehicle. Keep products sealed and stored so the driver cannot access them while the car is in use — think trunk or similar, the same way you’d treat an open alcohol container.
Crossing state lines with cannabis is illegal, even if both states have adult-use laws — that is a federal issue.
Home cultivation (adult-use)
Adult-use home grow opened under OCM rules (adult-use cultivation available since June 26, 2024 per OCM FAQ). High-level limits for adults 21+:
| Rule | Limit |
|---|---|
| Per person | 3 mature + 3 immature plants |
| Per private residence | 6 mature + 6 immature plants |
| Home flower possession | Up to 5 pounds (see OCM FAQ for concentrate equivalents) |
Plants must be secured and not plainly visible from public view. You cannot sell home-grown cannabis. Gifting without compensation to another adult 21+ is limited to the same personal amounts (up to 3 oz / 24 g). Full detail: OCM Adult-Use Home Cultivation FAQ (PDF).
Why licensed shops matter on Long Island
Only OCM-licensed retailers must sell tested, labeled New York products and follow the state’s rules. Unlicensed storefronts and gray-market delivery are enforcement targets and offer none of those consumer protections. Legal shops display license information and OCM’s dispensary verification tool.
Top Grass Bellport license (site footer): OCM-CAURD-25-000286. Verify retailers via cannabis.ny.gov.
Gifting vs selling
Adults 21+ may transfer limited amounts without compensation. Selling, bartering, or “gifting” cannabis while requiring purchase of something else is treated as an illegal sale outside the licensed market.
