Podcast king Joe Rogan said the mysterious drones buzzing around the tristate area left him “genuinely concerned” Sunday after watching a video that promoted an unconfirmed theory about unmanned devices detecting harmful substances.

John Ferguson, the CEO of a remote-controlled aircraft systems company in Kansas, claimed in a lengthy TikTok video on Saturday that the drones were trying to “smell” either a gas leak, “radioactive material” or something else on the ground.

“The only reason you would ever fly an unmanned aircraft at night is if you’re looking for something,” Ferguson said in the clip, noting that he doesn’t believe the drones are nefarious.

“So I think they’re trying to smell something on the ground – gas leaks, radioactive material, whatever,” the CEO said.

Ferguson added that the theory was his best guess based on his expertise and simply his opinion of the drone mystery gripping the East Coast, admitting, “I haven’t told anyone about this yet.”

“So if you think it’s bulls-t, whatever, that’s cool. “I don’t want to spread misinformation because we know there’s a lot of it going around,” he said in the TikTok video.

But his theory resonated with many online, including Rogan, who offered his dime for the drones that have been unnerving residents of New Jersey and New York for weeks.

“This is the first video about these drones that really concerns me,” he wrote on X on Sunday.

The popular podcast host previously called the US government’s claims “sus” after White House National Security Council spokesman John Kirby said the drones were not a public safety issue and that many of the reported sightings were actually manned aircraft .

Department of Homeland Security Secretary Alejandro Mayorkas also downplayed concerns about the drones on Sunday, claiming some of the drone sightings were due to relaxed regulations that allow the devices to fly at night.

“Some of these drone sightings are actually drones,” he said. “Some are manned aircraft, which are often confused with drones. And we’re seeing double coverage.”

Mayorkas also emphasized in an interview with ABC News on Sunday that the department has deployed personnel and technology “and if there is cause for concern, if we identify foreign involvement or criminal activity, we will communicate with the American people accordingly.”

“We are not aware of any at the moment. If something comes to our attention, we will communicate accordingly and take appropriate action,” he added.

The Post has reached out to DHS for comment on the latest theory.

A wide range of politicians – both Republicans and Democrats – made noise about the seemingly endless drone sightings in the tri-state area. New York Senator Chuck Schumer called on the government to use radar technology to identify the drone swarms.

Schumer, along with New York Sen. Kirsten Gillibrand, New Jersey Sen. Cory Booker and New Jersey Sen. Andy Kim, sent a letter last week to the FBI, Homeland Security and the Federal Aviation Administration demanding an explanation about what they do “Identify and address the source of these attacks.”
