In an interview that aired on CNN Wednesday night, Republican presidential candidate Rick Santorum told Piers Morgan that he had smoked marijuana while in college.

“I admitted back when I was running for the Senate that when I was in college I smoked pot, and that was something I did when I was in college, and it was something that I’m not proud of, but I did it,” he said. “And it is something I wish I hadn’t done, but I did and I admitted it and would encourage people not to do so.”

During the same CNN interview, Santorum defended his stance against same sex marriages.
