A new study shows the NYPD disproportionally arrests minorities for marijuana possession.

It was conducted by the Drug Policy Alliance, which hosted a rally outside of City Hall.

According to the study, 86 percent of those arrested for low-level possession were black or Latino.

The report also claims the NYPD has targeted nonwhite residents for marijuana arrests in neighborhoods that are predominantly white.

The organization says the numbers show a disconnect with Mayor Bill de Blasio's promise to end racially-biased policing.

"It is time to stop the racial disparity. It is time to stop this administration, that thinks it's a liberal administration, from continuing to arrest and destroy the lives of black and brown people," said Juan Cartagena, president and general counsel of Latino Justice.

"Today we stand here not only because we demand an end to the marijuana arrests, but we are also demanding that New York also join the rest of the country and legalize marijuana. Because it is time," said Kassandra Frederique, New York State director of the Drug Policy Alliance.

A spokesperson for the mayor referred NY1 to the NYPD for comments on the report.

The department did not immediately respond.
