Pres. JFK was a junkie. His poor medical condition and dependence on drugs has been covered up for a long time, but a number of details just leaked out. The NY Times reports:

In December 1962, after Jacqueline Kennedy complained that he seemed "depressed" from taking antihistamines for food allergies, he took a prescribed antianxiety drug, Stelazine, for two days. At other times he took similar medications regularly.

The records show that Kennedy variously took codeine, Demerol and methadone for pain; Ritalin, a stimulant; meprobamate and librium for anxiety; barbiturates for sleep; thyroid hormone; and injections of a blood derivative, gamma globulin, presumably to combat infections.

In the White House, Kennedy received "seven to eight injections of procaine in his back in the same sitting" before news conferences and other events, Dr. Kelman said. ...

For much of his life, Kennedy also suffered from severe and potentially dangerous bouts of diarrhea, which doctors suspected might have been from ulcerative colitis. Repeated examinations did not confirm that. Their ultimate diagnosis was spastic colitis, which today would be described as irritable bowel syndrome.

Kennedy took antidiarrheal drugs like Lomotil for relief, and he lost so much weight and strength from his ailments that he received the male hormone, testosterone, to build up his muscles. He also had high blood cholesterol, often in the range of 300, once at 410, which is twice the level now considered desirable.

Some of these are serious drugs. I doubt that Kennedy would have been elected if the public knew the facts.
