Long Island's legal cannabis map looks different from what most people assume. According to the state's Current OCM Licenses list (data.ny.gov, updated October 7, 2026), 17 adult-use dispensaries are operating on the Island, and every one of them is in Suffolk County. Nassau has no operating adult-use storefront, because most of its towns and villages opted out of retail sales when the state allowed them to in 2021. Six of the Suffolk shops opened in 2026 alone, so the roster is still filling in.
That makes Suffolk, and especially the Farmingdale line and the Town of Brookhaven, the center of the Island's licensed market. Below are the shops we think are worth knowing, grouped by area, plus a Queens store just over the city line that Nassau residents regularly use.
How we chose: These are research-based picks. We compiled them from state license records, each shop's own website and posted policies, and public reviews, and we only include stores holding an active license. No shop paid to appear here, and the descriptions are not based on staff visits. Hours, deals and delivery zones change often, so confirm with the shop before you drive.
Western Suffolk: the Farmingdale and Deer Park cluster
Despite the Farmingdale mailing addresses, the three stores below sit in East Farmingdale on the Suffolk side of the county line, along Route 110, Route 109 and Wellwood Avenue. They are the closest licensed options for most Nassau shoppers.
Strain Stars
Strain Stars, at 1815 Broadhollow Road (Route 110), has the earliest opening date of any Long Island store on the state's license list: July 2023, under a conditional (CAURD) license. It is a straightforward, well-stocked counter with pickup and delivery ordering online, and the company's site now lists sister stores in Riverhead and White Plains. State records show it open 9 a.m. to 9 p.m. Monday through Saturday and 10 a.m. to 8 p.m. Sunday. Good for: Route 110 commuters and anyone who wants a long-established Island shop.

Happy Days
A short hop away at 105 Route 109, Happy Days (CAURD license, open since the turn of 2024) is the Island's strongest pick for delivery: it advertises free same-day drop-off to homes and businesses across both Nassau and Suffolk, seven days a week, in unmarked cars. The menu runs past 1,000 products, leashed pets are welcome on the floor, and QR-code pickup has no minimum. Hours are 9 a.m.–9 p.m. Monday through Saturday and 10 a.m.–8 p.m. Sunday. The owners also hold a license for a second store on Western Avenue in Albany. Read our full profile
Planet Nugg
Planet Nugg, at 2043 Wellwood Avenue, is the education-minded option in the cluster. The 5,000-square-foot, space-themed CAURD shop carries roughly 1,700 products sorted by category, and budtenders work from iPads so they can pull up product details at the counter, which helps if you have a lot of questions. Delivery covers about 25 miles around Farmingdale (Fire Island excluded) with a $100 minimum and no fee. The shop also funds scholarships at Farmingdale State College and runs Narcan trainings. Open 9 a.m.–9 p.m. Monday through Saturday, 10 a.m.–8 p.m. Sunday. Read our full profile
Long Island Cannabis Club
A few miles east, Long Island Cannabis Club sits at 94 East Industry Court in Deer Park, close to the Tanger Outlets. The 4,200-square-foot CAURD store opened in November 2024, more than a year after its license was issued. It's a practical pick for deal-watchers: posted specials include 15% off the whole store Tuesday through Friday and pre-roll discounts on Mondays, with no membership required. Delivery reaches a long list of towns, among them Commack, Brentwood, East Islip, Sayville, Patchogue and Bellmore. Open 9 a.m.–9 p.m. Monday to Saturday and 10 a.m.–8 p.m. Sunday.

Central Suffolk: Brookhaven's shops
The Town of Brookhaven has become the Island's second hub, with stores spread across the North Shore, Route 25 and the Long Island Expressway corridor.
Strong Strains
On the North Shore at 19 Technology Drive in East Setauket, Strong Strains (CAURD license, opened June 2025) is built for shoppers hunting a specific brand: its online directory listed 223 New York brands this month, from Ayrloom and MFNY to Florist Farms. It offers both pickup and delivery, with minimums that depend on your address, and stays open until 11 p.m. Thursday through Saturday, which is late for Suffolk. The website shows two slightly different schedules, so check before a late run. Good for: Stony Brook and Three Village locals. Read our full profile
Simply Green
Simply Green, at 406c Middle Country Road (Route 25) in Coram, is a single-location, family-run CAURD shop that opened in November 2025. State records list its trade name as "Peace of Woodstock," which explains the front room of band tees, candles and collectibles that makes it a good stop for gifts. The discounts stack in shoppers' favor: 10% off every day, an extra 10% for seniors, veterans, medical patients and first responders, and a first-visit discount. Note that it does not deliver; online orders are for in-store pickup, and it takes cash, debit and Dutchie Pay. Open until 10 p.m. on Fridays and Saturdays. Read our full profile
The Joint Venture
The Joint Venture, at 2 Munsell Road in Medford near the LIE, opened in February 2026 under a standard adult-use retail license, and its schedule is the headline: 7 a.m. to 11:30 p.m. every day, the widest window on the Island. Delivery covers most of Suffolk with a $75 pre-tax minimum, while pickup has no minimum and runs in one-hour slots. The points program starts new members with 200 points and pays out $600 at 10,000. In-store payment is cash or debit, and the debit and ATM fees add a few dollars, so plan accordingly. Read our full profile
Just over the city line (Queens)
Because Nassau has no adult-use storefront, many western Nassau shoppers cross into Queens. This store is inside New York City rather than Nassau or Suffolk, but it sits right at the county line.
Green Flower Wellness (Glen Oaks)
At 270-01 Hillside Avenue in Glen Oaks, steps from the Nassau line near North New Hyde Park, Green Flower Wellness is the late-night answer: open until 2 a.m. seven nights a week, with a free lot for 30-plus cars. The minority- and women-owned group runs three Queens stores, and its same-day delivery to Queens and Nassau runs out of the Oakland Gardens location. A rewards program adds points and birthday discounts. Read our full profile

Update: October 2026
Suffolk's licensed market grew quickly this year. State records show six adult-use stores opening in the county in 2026, including The Joint Venture in Medford and new shops on the South Fork and in West Babylon. Brookhaven also saw friction: in January, Strong Strains announced an "official reopening" and publicly pointed to the town special use permit and certificate of compliance it already held, after a dispute with the Town of Brookhaven. A large group of additional Suffolk licensees, many in West Babylon, Deer Park and Riverhead, are still listed as non-operational, so expect more openings. Nassau remains closed to adult-use retail.
Shopping tips for Long Island
- Bring a valid 21+ photo ID. Out-of-state licenses and passports are accepted if unexpired.
- Carry cash or debit. Most shops are cash-and-debit only, and debit or ATM fees of a few dollars are common.
- Know the limits. Adults can buy and carry up to three ounces of flower and 24 grams of concentrate; see how much cannabis you can legally buy and carry in New York.
- Verify the license. Unlicensed smoke shops still operate on the Island. Look for the OCM verification sticker at the door, check the state's dispensary verification tool at cannabis.ny.gov, or browse licensed dispensaries on High Today.
- Stack the savings. Several shops above run loyalty points and daily discounts; our guide on how to save at New York dispensaries explains how to combine them.
- Don't drive impaired, and keep purchases sealed in the trunk on the way home.

Pick Happy Days or Planet Nugg if you want delivery from the west end, The Joint Venture for odd hours, Strong Strains for brand depth, and Simply Green for discounts and gifts.
