Buying Legally In New York

A few things worth knowing before you visit:

  • You must be 21 or older with a valid government-issued photo ID.
  • New York's adult-use possession limit is commonly cited as up to 3 ounces of flower or 24 grams of concentrate at one time.
  • State cannabis taxes apply at checkout.
  • You can confirm any retailer's license at cannabis.ny.gov, which lists the state's licensed adult-use dispensaries. If a shop doesn't appear there, it isn't licensed.
