Family.

Grand Street Cannabis Co. is a family-owned and operated, licensed New York State adult-use cannabis producer. Based in Westchester, we bring more than a decade of legacy experience into the legal market, with a deep connection to the culture, the people, and the plant that brought us here.

Our focus is simple: exceptional flower. We specialize in unique cultivars, modern classics, and elite cuts from some of the world’s foremost breeders. We source directly from breeders because genetics matter. No shortcuts, no chasing trends, no compromise.

No shitheads philosophy.

We have one simple rule: no shitheads. We work with people we actually want to be around. Talent, character, perspective, energy—all of the above. We show up, we do what we say we’re going to do, and we don’t quit when things get difficult.

That’s the standard. Find good people. Keep good people. Be a good person to work with. And never compromise.

Honor among thieves.

There’s an honor among thieves—an unspoken bond built on loyalty, trust, and standing by your people when it matters most. We carry that same code into everything we do: a commitment to each other, a promise to never compromise on quality, and a dedication to putting products into the marketplace that we can stand behind with pride.

Our strength comes from the people beside us. We move as one, hold each other accountable, and keep our word— when our name is on the product, there is no room for anything less than solid.
