Barack Obama's drug history

"You know, I made some bad decisions that I've actually written about. You know, got into drinking. I experimented with drugs," he said. "There was a whole stretch of time that I didn't really apply myself a lot. It wasn't until I got out of high school and went to college that I started realizing, 'Man, I wasted a lot of time."'

Obama has written about his drug use in his memoir, "Dreams from My Father."

"Junkie. Pothead. That's where I'd been headed: the final fatal role of the young would be black man," Obama wrote. Mostly he smoked marijuana and drank alcohol, Obama wrote, but occasionally he would snort cocaine when he could afford it.

Drugs, Obama wrote, were a way he "could push questions of who I was out of my mind, something that could flatten out the landscape of my heart, blur the edges of my memory."

Blur the edges of my what now? I forgot what I was reading.
