This Denver Post interview suggests that Mitt Romney is not taking a hard line on medical marijuana, a hot-button issue in Colorado.

Romney also was hazy about the future of Colorado's medical marijuana industry, which reaps more than $5 million a year in state sales taxes, saying his administration would enforce federal drug laws, that prohibit marijuana for any use.

"I oppose marijuana being used for recreational purposes and I believe the federal law should prohibit the recreational use of marijuana," he said.

But whatever his reason was for singling out "recreational" use in that interview, Romney's position on pot hasn't changed.
