Mayor Eric Adams of New York on Wednesday visited a pizzeria in Queens that was once an illegal smoke shop to celebrate the success of his administration’s crackdown on illegal cannabis shops, even as the city is bracing for a potential resurgence.

Mr. Adams said the pizzeria, which is named Salsa and opened in Rego Park in March, demonstrated how the enforcement against illegal weed sellers has paved the way for other small businesses to open and for the legal cannabis industry to thrive.

“We went from illegal items that were harmful to communities to pizza, good food, good-paying jobs and a support system,” he said.

The mayor said his administration has shut down about 1,400 smoke shops since the crackdown started last May. At the same time, the number of licensed cannabis dispensaries in the city has surpassed 160 and generated more than $350 million in sales.

In the wake of state lawmakers’ decision to legalize recreational marijuana in 2021, the number of unlicensed weed shops exploded throughout the city, undercutting licensed dispensaries before they had the chance to open. The move to shutter the renegade shops — which in Manhattan alone vastly exceeded the number of Starbucks coffee shops — was widely applauded.

But the court orders that allowed the city sheriff to seal the illegal businesses with padlocks for one year have begun to expire, requiring the city to remove the locks.
