Big Apple smokers have a message for their cigarette-hating coworkers — butt out.

Smokers interviewed by the Post Tuesday were less than pleased with a new study that found the vast majority of New Yorkers don’t want co-workers — or anybody for that matter — lighting up outside their jobs, even as fewer and fewer businesses allow employees to smoke near the entrance.

“I’m outside. It’s free air,” said Annette Rusch, 51, who was puffing away outside Brooklyn’s Woodhull Medical Center. “To each their own. I don’t try to blow smoke on people’s faces, but the air circulates. I’m not trying to harm you. I don’t understand why people have a problem.”

The survey by the nonprofit Public Health Solutions found that nearly 80% of New Yorkers surveyed prefer a smoke-free space outside their workplace — including 58% of folks who currently smoke.

“No one ever told me about this!” exclaimed another grumpy puffer who identified himself only as Derrick. “Anywhere I smoke I’m allowed to. People shouldn’t have any issue with it. You can’t smoke in hotels, you can’t smoke in a lot of places now. But as I get older it doesn’t matter too much now. I don’t care.”

One lifelong smoker said he’s been lighting up since he was four years old and isn’t quitting now.

“I have been smoking 55 years and I don’t agree with smoking, (but) it’s my fault and my decision,” he said. “People can believe what they want but they can also do what they want.”

The Bronx tops the list of job sites that still allow smoking in at least some areas of the workplace, with 33%, among the five boroughs, with Queens second (28%), followed by Brooklyn (27%), Staten Island (26%) and Manhattan (22%).

There are more than 800,000 adult smokers in the state, who account for $10 billion in health care costs every year, according to the city Department of Health and Mental Hygiene.

New York City has increasingly limited where smokers can light up, including last year’s ban on smoking at all NYCHA buildings and grounds.

City law also prohibits smoking in any public indoor spaces, including hotel bars and lobbies, and at any city park, beach, playground or golf course. Smoking is also barred on public transportation vehicles, airports and at sports arenas.

But smokers have occasionally pushed back. In 2011, tobacco aficionados held a “Smoke in the Park Event” to protest the newly enacted ban on public smoking, risking $50 fines by puffing away on the Brighton Beach boardwalk. None were ticketed.

Not all smokers were on fire over the survey results.

“People should respect privacy,” said Adelaida, 61, who was at the hospital for an appointment. “When I’m on a bus stop if somebody’s sitting, I won’t light up a cigarette and they might have health issues. I respect it. Even here, I’ll go down the block.”
