Is doing drugs a requirement to be a US President?

George W. Bush = Admits to doing drugs and drinking.

Look no further than President Bush, a recovering alcoholic who, when asked about illegal substance use in a misbegotten past that extended well into his 30s, would say no more than, "When I was young and irresponsible I was young and irresponsible."

Bill Clinton = Said he smoked marijuana.

The famous kerfuffle when then-candidate Bill Clinton said that he'd tried marijuana but didn't inhale began on March 29, 1992 - nearly 15 months later in the election cycle than this story has hit the national media.

Barack Obama = Admit to doing illegal drugs and drinking.

Long before the national media spotlight began to shine on every twist and turn of his life's journey, Barack Obama had this to say about himself: "Junkie. Pothead. That's where I'd been headed: the final, fatal role of the young would-be black man. . . . I got high [to] push questions of who I was out of my mind."
