Big Apple health officials unveiled a new street vending machine Monday that swaps out candy bars and potato chips for free doses of Narcan and drug-testing strips.

Designed to combat the surge in overdoses in the five boroughs, the new machine in Brownsville, Brooklyn, is the first of four set to pop up in some of the city’s most drug-infested neighborhoods in the coming months, officials said.

“Every three hours, we’re losing a New Yorker [to drugs]. And it looks like 2022 is on track to be our highest year ever in overdoses,” Health and Mental Hygiene Commissioner Ashwin Vasan said at a press conference next to the machine, which is parked outside a nonprofit aimed at offering housing and other support for those in need.

“We have a rising tide of fentanyl, and now we have other substances entering our drug supply, which is really putting us behind the eight ball,” Vasan said.

He specifically noted the increasing presence of Xylazine, a veterinary drug known as “Tranq” or the “zombie drug” that can leave users in a catatonic state and with conditions that eat their flesh off.

“We’re looking to stock these machines with those [test strips] as well,” Vasan said.

The contraption looks like a typical snack vending machine but is stacked with potential life-saving tools instead.

The available goods include the overdose-busting drug Naxolone, commonly known by the brand name Narcan, drug-test strips that detect fentanyl and other opioids, safe-smoking kits with a heavy stem pipe and assorted items such as condoms, tampons, nicotine gum and first-aid kits.

People don’t have to pay for the items; they simply punch in their zip code to get access.

While the first machine does not include syringes, future ones may include them, Vasan said.

The machines, which cost $11,000, will be installed in areas most plagued by drug overdoses, he said.

“This is an important arrow in our quiver,” Vasan said of the vending machines. “It’s not the be-all and end-all solution, but it’s an important tool that says to New Yorkers, ‘Hey, we are going to bring the tools that saves lives to you.’ “

Officials first announced early last year that they were moving ahead with the pilot program, as drug overdoses spiked in the city.

According to Big Apple data, 2021 was a record year for fatal overdoses in the five boroughs, with 2,668 drug deaths.

Although 2022 numbers have not yet been completely compiled, health officials said the yearly figure is expected to eclipse the 2021 record. The first half of last year alone saw 1,370 fatal overdoses, the stats show.

About 80% of those were fentanyl overdoses.

But with the US Drug Enforcement Administration now calling Tranq “the deadliest drug threat” in the US, “we have new Xylazine test strips similar to the fentanyl test strips [which] allow people who use drugs to identify whether there is Tranq in whatever they’re using” and they could be added to the vending machines, too, Vasan said.

While the anti-drug vending machines will be new to New York City, Vasan said they have already been installed elsewhere, including in Philadelphia and Nevada in the US and in Australia and in Denmark in Europe.

“The answer to the opioid crisis is more,” the commissioner said. “More tools, more education, more harm-reduction, more stigma-busting, more treatment.

“We are up against an ever-growing crisis and we need to get our arms around it, which is what we’re doing here today,” he said.
