Taking "a drug"! LOL. Such dishonesty. Per the Robert Halleck book that uncovered the full list of drugs being taken by JFK while president for the first time decades after his death.
Kennedy took as many as 12 medications at once, taking more during times of stress.
The medical records reveal that Kennedy variously took codeine, Demerol and methadone for pain; Ritalin, a stimulant; meprobamate andlibrium for anxiety; barbiturates for sleep; thyroid hormone; and injections of a blood derivative, gamma globulin, a medicine that combats infections.
During the Bay of Pigs fiasco in 1961, and the Cuban Missile Crisis in October 1962, Kennedy was taking steroids for his Addison's disease, painkillers for his back, anti-spasmodics for his colitis, antibiotics for urinary tract infections, antihistamines for his allergies, and on at least one occasion, an anti-psychotic drug to treat a severe mood change that Jackie Kennedy believed was brought on by the antihistamines.
This deluge of drugs often had side effects, including grogginess or even depression. To treat this Kennedy took more still anti-anxiety medications.
