We do know he's tried water, though
I don't really care whether or not Marco Rubio has ever smoked a joint, but it's hilarious how much thought he's put into
explaining why he won't say if he has:
“If you say that you did, then suddenly there are people out there saying, ‘Well, it's not a big deal,’” Rubio said. “On the other side of it is if you tell people that you didn't, they won't believe you.”
Rubio explained that his decision not to answer the question goes back to an encounter he had after publishing his memoir, “American Son.” In the book, Rubio reveals that he was not a disciplined student in his youth and had a 2.1 GPA in high school.
“Someone came up to me and said, ‘You know, I enjoyed your book, but I want you to know, my son came up to me and said he doesn't have to get good grades in high school, because look at Marco Rubio, he didn't do well in high school and look how successful he's been,’” Rubio recalled.
“And that impacted me,” he said of the encounter.
My first reaction to this was that Rubio sure sounds like a guy who has smoked an awful lot of dope and doesn't want to talk about it before a presidential primary. But the more I think about it, I'm wondering if the opposite isn't possible: Maybe Rubio has never smoked a joint and he's too embarrassed to admit it. Then again, maybe he's smoked so much he just can't remember.
