The Daily Mail first reported that Cruz had used the drug.
"Teenagers are often known for their lack of judgment, and Sen. Cruz was no exception," a Cruz spokesman told the British paper. "When he was a teenager, he foolishly experimented with marijuana. It was a mistake, and he's never tried it since."
The admission makes Cruz the latest presidential candidate to own up to trying the drug. Former Florida Gov. Jeb Bush (R) recently copped to smoking pot while in high school as well.
