With medicinal marijuana licenses in hand, New York dispensaries are finally gearing up to sell cannabis legally beginning Thursday.

Columbia Care arguably has one the buzziest dispensary locations in New York City’s Union Square neighborhood. The state in July granted five medicinal marijuana licenses.

Nicholas Vita, a former Goldman Sachs investment banker, runs Columbia Care. He’s gearing up to open his shop on 14th Street. Business neighbors include a CityMD office and a Chickpea restaurant.

“Almost every subway line in the city touches Union Square, which makes the location incredibly accessible,” said Vita, Columbia Care’s chief executive.
