“You’ve got a 10th Amendment argument but you’ve got a supremacy clause question,” Sandoval said. “And then I don’t know how you distinguish between medical and recreational, at least based on a federal law enforcement perspective, at least as the law is written now.”

But then there’s the whole money issue. States are now making money by taxing weed.

“No absolutely, there’s no doubt,” Sandoval said, who expects to send his education department about $30 million a year from weed money. “It is extra money. But it is. And it’s important to me to continue the quality of education. And you know that’s something they’ve done in Colorado, something they’ve done in Washington, something they’ve done in Oregon.”

Over in Colorado, Democratic Gov. John Hickenlooper opposed legalizing weed, but his state is now reaping about $140 million annually from pot taxes. He still isn’t a fan of pot, but he argued his state is a test case.

“But I think if this works, we will have some revenues to address some of the consequences of drug use—so mental health, addiction counseling, those kinds of things,” he told The Daily Beast.
