A top Drug Enforcement Administration agent slammed Mayor de Blasio’s stance on marijuana during an interview Sunday.

DEA Special Agent in Charge of New York James Hunt said that as long as anti-weed laws are on the books, he “won’t stop enforcing them.”

Hizzoner announced last month that he wants the NYPD to stop busting public pot smokers, but as Hunt said on John Catsimatidis’ AM 970 radio show, “It’s still against the law federally.

“It’s still a Schedule 1 substance not approved by the FDA . . . We will not stop enforcing, because Congress makes these laws,” he said.

“As long as it’s illegal, the federal government will enforce the laws,” Hunt added.

Some residents are worried de Blasio’s edict could lead to more widespread public drug use, but the mayor has maintained the city needs new drug policies as the state is studying legalizing recreational pot.
