Not an easy sell for the woman who is always asking, "But, what about the children?!" But, 2 Chainz--wearing a very professional looking cardigan, white button down and only one chain (a cross)--came prepared with an argument that states legalizing marijuana could help reduce overcrowding in prisons and help keep small time pot enthusiasts from getting criminal records that make it hard for them to get a job.

He also brought up the fact that legalizing marijuana would allow it to be taxed, which would help the economy. "We're in a deficit. We've got to find ways of getting out," he said (watch in the video above). "If we got half of the states legalizing pot, if the rest of the community legalizes pot that frees up taxpayers money, that'll allow us to do something with this extra with these funds from fixing potholes in the street to building stadiums. I'm down with it."

Grace was not as down with it, calling out stories of little kids who were able to get their hands on drugs. But 2 Chainz had a calm, reasonable response to that.

"Anybody that loves their kid definitely knows not to put them in harm's way, I don't agree with that at all," he said. "[The mother] might have mental issues. It may be something deeper than a joint."
