More than a dozen U.S. Air Force airmen faced disciplinary action — including court martial — after a drug ring was found operating at a base that controls America's nuclear missiles, the Associated Press reports .

Military investigators cracked the ring in 2016, after one of the service members made the mistake of posting material to social media that suggested the drug use.

Nearly half of the airmen were convicted of using or distributing LSD – a drug for which the Pentagon had stopped testing, the AP says. Citing records obtained under the Freedom of Information Act, the AP reports that the drug ring operated at Francis E. Warren Air Force Base, just outside of Cheyenne, Wyoming.

The airmen took the drugs — which also included ecstasy, cocaine and marijuana — during their off-duty time, but at least one airman admitted that while under the influence of LSD, he wouldn't have been able to respond properly if he had been suddenly called to duty.

Evidence in the airmen's cases showed that they did the drugs state parks or at parties in Denver — where a group went longboarding on the streets after taking LSD, the AP says. It also includes quotes from some service members who recalled having "bad trips" – and others who said their experiences had been positive.

"Minutes felt like hours, colors seemed more vibrant and clear," Airman Basic Kyle S. Morrison is quoted saying. "In general, I felt more alive."

But Air Force prosecutors had a different view, saying that taking the powerful hallucinogenic drug can produce "paranoia, fear and panic, unwanted and overwhelming feelings, unwanted life-changing spiritual experiences, and flashbacks."

Warren is the headquarters of the 20th Air Force, which oversees three missile wings. While the personnel there are held to a high standard because of their work securing Minuteman 3 intercontinental ballistic missiles, the AP notes that the assignments are sometimes seen as a "backwater."

More than 400 Minuteman missiles, each capable of delivering devastating nuclear blows, are deployed around Warren and other bases, the Air Force says .

Six of the airmen were convicted of drug offenses in courts martial. They're among 14 service members who faced disciplinary measures over the investigation — which came on the heels of other scandals involving the U.S. missile corps.

Those recent incidents include the use of narcotics by officers with launch authority , and rampant cheating on proficiency exams – which was seen as both manipulating the promotion process and masking security lapses .

Revelations about drug use at Warren also come less than five years after the Air Force's No. 2 missile commander, Maj. Gen. Michael Carey — who led the 20th Air Force that is headquartered at Warren — was relieved of command over "drunken and inappropriate behavior while leading a security delegation to Moscow."

Reporting on the recent drug case, the AP quotes Capt. Charles Grimsley, a lead prosecutor in some of the courts martial, saying, "Although this sounds like something from a movie, it isn't."
