An East Harlem deli owner was arrested Thursday for letting New Yorkers use taxpayer-funded food stamps to buy illegal drugs and cigarettes, authorities said.

Yousif Mosleh, who operates a deli at 125th Street and Lexington Avenue and owns another one nearby, was charged in Manhattan federal court with distributing controlled substances and violating US laws governing food stamps. He faces up to 45 years in prison.

The feds said he let government cooperators buy “K2,” a synthetic form of marijuana, using their EBT cards, a type of debit card for low-income families.

In arresting Mosleh, 26, NYPD recovered 1,396 packages labeled “Xtreme” that appear to be K2, according to the complaint.
