Manhattan’s top federal prosecutor hinted this week at plans to possibly shut down the city’s two safe injection centers, which he said are illegal and “unacceptable” under a longstanding federal law.

“I have repeatedly said that the opioid epidemic is a law enforcement crisis and a public health crisis. But I am an enforcer, not a policymaker,” Damian Williams, the U.S. attorney for the Southern District of New York, told The New York Times of the OnPoint NYC overdose prevention centers (OPCs) in East Harlem and Washington Heights.

“My office is prepared to exercise all options — including enforcement — if this situation does not change in short order,” he added.

One parent — whose child attends a school across the street from the group’s East Harlem site — immediately cheered Williams’ comments.

“That just made my day — I hope they do close it,” parent Francesca Barreiro told The Post. “There should never be a drug facility across the street from kids. This would never happen in another area.”

“We want them gone,” another parent added.

The OnPoint centers, which opened in November 2021, allow visitors to use illegal drugs like meth and cocaine while supervised by licensed workers in hopes overdoses will be spotted before it’s too late. But some critics say there is no proof they actually work.

Williams said the safe injection centers are “unacceptable” due to the so-called “crack house statute,” a provision of the 1986 Anti-Drug Abuse Act that prohibits individuals or organizations from maintaining a property for the purpose of making, selling, or using a controlled substance.

When reached by The Post Wednesday, Williams’ office declined to comment on whether it planned to shut down the OnPoint centers in the near future.

OnPoint’s OPCs were authorized via an executive action by former Mayor Bill de Blasio in November 2021.

Earlier this year, Mayor Eric Adams pledged that the city would have five new safe injection sites by 2025.

“As the Biden administration funds a study into the operations of our OPCs as a potential tool to help combat our nation’s overdose crisis, OnPoint is proud to continue its work with city, state and national officials to save lives and strengthen New York’s response to a devastating health crisis,” OnPoint executive director Sam Rivera told The Post in a statement Wednesday.

“Our successful partnership with the New York Police Department highlights the effectiveness of responding to this crisis with love and care, rather than enforcement. As always, we welcome a continued dialogue with government leaders.”

The injection sites have their critics, however, such as Staten Island Republican and City Council Minority Leader Joe Borelli.

“Not only are safe injection sites counterproductive to bettering our drug crisis, they’re illegal plain-as-day under federal law,” Borelli told The Post. “The DOJ should remind the Health Department about federal law.”

Despite this, the organization says it’s saving lives — in the 20 months since OnPoint’s doors opened, workers have prevented more than 1,000 overdose deaths, a spokesperson said.

“No one has to die of a drug overdose. Harm reduction isn’t a radical and untested experiment. The data and evidence are clear. There are thousands of beautiful souls that are still with us today because of the intervention of our OPC staff,” Rivera argued.

Because the OnPoint staff can intervene quickly, most overdoses are remedied by administering oxygen, the organization explained to The Times.

One OnPoint employee — who declined to give her name — told The Post she hopes the center stays open because it’s helping the community.

“Hopefully we can convince them otherwise,” she said. “I just want to keep my community alive. I want these young men to go home and not overdose. Education, case management, so many elements that keep them alive.”

OnPoint’s clients are similarly fond of the place.

“This is a safe haven for people, and for someone to want to take it away is foolish,” Aaron, a 55-year-old recovering addict, told The Post. “This place is helping people in many ways with meals, clean needles … they even teach you how to use Narcan if someone needs.”

“There’s no reason why they should stop this — unless they’re set on just making arrests,” he continued. “People make assumptions about what’s going on — but it’s helping people.”

“The centers are licensed by the state and closely monitored by the city health department,” City Hall spokesperson Kayla Mamelak told The Post.

“Ultimately, like the US Attorney, we are awaiting state or federal policy to definitively set out a regulatory framework for these lifesaving supports,” Mamelak said.

The centers’ standards and expectations are being codified, a source with the mayor’s office said. And they’ll eventually be available to the public.

The debate about the centers comes as New York City and the rest of the country battle an increasingly dire drug overdose crisis.

In 2021, 2,668 people died from overdoses in the city alone, according to the Health Department.

Last year, Gov. Kathy Hochul declined to use some of the state’s $2 billion settlement from opioid manufacturers to open more supervised consumption centers, Gothamist reported.

Efforts to permit OPCs have also failed at a state and city level, The Times said.

And not everyone is thrilled with the street environment the centers’ clients create.

Outside the East Harlem site, the addicted clogged the block and intimidated those passing by — throwing fuel on a fire kept warm by parents who steadfastly maintain the centers should close.

“You have to move out the way because they’re dozing off, they’re passing out,” parent Francesca Barreiro said.

“Down on the corner, my kid will see someone with a needle in their arm,” she continued. “Why do I have to explain to my kid why that guy has a needle in his arm?”
