Police seized more than 800 lbs of marijuana with a street value of more than $6 million at a Deer Park warehouse on Wednesday.
Rolando Morris, 39, of Newburgh, and Johana Velez, 30, of Central Islip, were both arrested when they received a shipment of the marijuana, New York State police said.
They were charged with criminal possession of marijuana.
Morris was also charged with criminal possession of a weapon after police say they found a loaded handgun at the time of his arrest.
They will be arraigned Thursday at First District Court in Central Islip.
