Whether you live in Nassau or Suffolk County, from Hempstead to Huntington or all the way out in the Hamptons, you have probably been wondering about the new cannabis rules. It can be a little confusing, and you might be asking the same big question: Is weed legal in Long Island? We are here to tell you that the answer is absolutely YES!

Weed is legal for adults on Long Island. However, our island has a very unique and sometimes tricky situation when it comes to buying it. This guide will explain everything in a simple way.

The Foundation: Long Island Follows New York State Law

The first thing to know is that there are no special Long Island cannabis laws. Both Nassau and Suffolk counties have to follow the same big law as the rest of New York State.

The main law is called the Marihuana Regulation & Taxation Act (MRTA). It’s the law that made cannabis legal for all adults in New York. The most important rule in the whole law is that you must be 21 years old or older to have, use, or buy cannabis.

What’s Legal to Have, Use, and Grow

The state law gives everyone clear rules on what is okay and what is not okay. These rules apply to every single town on Long Island, from Valley Stream to Montauk Point.

Possession Limits (What you can carry)

When you are out and about on Long Island, there is a limit to how much cannabis you can have with you. You are allowed to carry up to 3 ounces of cannabis flower and up to 24 grams of cannabis concentrates, like vape oils.

This means you can have your legal amount of cannabis with you, whether you are heading to the city for the day or driving out to the beach for the weekend.

Public Consumption Rules (Where you can’t smoke)

This is a very important rule for all Long Islanders. The general rule is simple: you can smoke or vape cannabis in most places where you can smoke a cigarette.

However, there are many places where you CANNOT smoke. Think about all the public places you visit. You can’t smoke at Jones Beach, on the Long Island Rail Road, or in any public parks like Eisenhower Park or Heckscher State Park. You also cannot smoke inside a car that is on a road, like the LIE or the Southern State Parkway.

Home Cultivation

The law also allows you to grow your own cannabis plants right at home. Any adult can grow up to 6 plants for their own personal use. Only 3 of these plants can be mature, flowering plants at one time.

If you have more than one adult living in your home, the house can have a maximum of 12 plants. This is a great way to have your own supply without ever having to go to a store.

The Big Long Island Twist: Why Is It So Hard to Find a Dispensary?

Here is where things get a little different for us on Long Island. Even though weed is legal to have, it can be very hard to find a place to buy it legally.

The state law allowed every town and village to make a choice. They could either “opt-in” and allow legal recreational dispensaries to open, or they could “opt-out” and ban them. Unfortunately, the vast majority of towns that opted out on Long Island said no to dispensaries.

This means that even though is weed legal in Long Island is a yes, finding a legal recreational shop in Nassau or Suffolk is very, very difficult. There are very few of them compared to other parts of New York.

Medical vs. Recreational: The Smart Choice for Long Islanders

This difficulty in finding a recreational shop is a big reason why the medical marijuana program is still the best and smartest choice for people on Long Island. A medical card is like a key that unlocks better, easier, and more affordable access.

Here is why having a medical card is the better path on Long Island:

• You Can Actually Find a Dispensary: Medical dispensaries have been open on Long Island for years. They are established and easy to find, so you have consistent and reliable access to your medicine.

• You Save a Lot of Money: Recreational cannabis has a high 13% tax. But medical cannabis patients do not have to pay this tax. This can save you a huge amount of money over the year.

• You Get More and Better Care: With a NY Medical Marijuana Card, you can have a “60-day supply,” which is often much more than the 3-ounce recreational limit. You also get products that are made for your specific medical conditions.

Frequently Asked Questions (FAQs) for Long Island Residents

Living on the island comes with its own unique set of questions. Here are a few common ones that Long Islanders ask.

Can I smoke weed on a boat in the Great South Bay?

You have to be very careful with this. It is illegal to operate a boat while under the influence of cannabis, just like with alcohol. The public smoking rules also still apply on the water, so it’s best to avoid it.

If I buy legal weed in NYC, can I bring it home on the LIRR?

Yes, you can. As long as you are 21 or older and you are carrying an amount within the legal limit, you can bring it home with you. Just remember, you absolutely cannot smoke or use it on the train.

Which towns on Long Island have dispensaries?

The list of towns with legal recreational Suffolk County dispensaries and Nassau County weed rules for sales is very short and changes slowly. The best way to know for sure is to check the official New York State Office of Cannabis Management (OCM) website. They have a dispensary location finder that is always up to date.
