The Republican presidential debate is taking place tonight in the heartland of the country's legal cannabis industry - Boulder, Colorado. That's a great table-setter for a robust conversation on legalization. Let's hope they deliver. As an appetizer, here's a sampling of quotes from Republican candidates that reflect their views on the issue.

Jeb Bush: "I thought [legalizing cannabis] was a bad idea, but the states ought to have the right to do it. I would have voted no if I was in Colorado," Feb. 27, 2015.

Ben Carson: "I have no problem with medical marijuana. But that is very different from legalizing it for recreational use. I would not do that under any circumstances," Sept. 22, 2015.

Chris Christie: "If you're getting high in Colorado today, enjoy it. As of January 2017, I will enforce the federal laws," July 28, 2015.

Ted Cruz: "When it comes to a question of legalizing marijuana, I don't support legalizing marijuana. If it were on the ballot in the state of Texas, I would vote no. But I also believe that's a legitimate question for the states to make a determination," Apr. 16, 2015.

Carly Fiorina: "The marijuana today is not the same as what Jeb Bush smoked 40 years ago. Drug addiction is an epidemic and it is taking too many of our young people," Sept. 16, 2015.

Mike Huckabee: "This idea of recreational marijuana, let's let Colorado have at it for a few years and let's see how that works out for them. I've been to Amsterdam a few times; I don't want us to look like Amsterdam. And a lot of people in Colorado aren't liking the way that's headed either," Oct. 17, 2015.

John Kasich: "I'm totally opposed to [legalizing cannabis], because it is a scourge in this country," Kasich said. "In my state and across this country, if I happened to be president, I would lead a significant campaign down at the grassroots level to stomp these drugs out of our country," Apr. 21, 2015.

Rand Paul: "One of the problems is the federal government has come into states that have allowed medical marijuana and still harass them so I think the federal government ought to stay out." July 1, 2015.

Marco Rubio: "I think we need to enforce our federal laws. I don't believe we should be in the business of legalizing additional intoxicants in this country for the primary reason that when you legalize something, what you're sending a message to young people is it can't be that bad, because if it was that bad, it wouldn't be legal," Apr. 14, 2015.

Donald Trump: "I think [legalization's] bad, and I feel strongly about that. They've got a lot of problems going on right now in Colorado, some big problems," Feb. 27, 2015.
