A medical marijuana dispensary will open this month a few blocks from the U.S. Capitol, which McClatchy Newspapers calls “one of the boldest moves yet for the nation's marijuana movement, which is in full bloom this spring.” It will be one of three that are expected to be operating soon in Washington, D.C. Illinois legislators just passed a law legalizing medical marijuana, though it has yet to be signed by the governor, and New Hampshire and Vermont may be close behind. “Medical marijuana has been a Trojan horse, really, for decriminalization and legalization. It's the slippery slope toward legalization,” said former Rep. Patrick Kennedy of Project SAM (Smart Approaches to Marijuana), a national group that opposes legalization. Stuart Taylor of the Brookings Institution said allowing the D.C. dispensary is “totally inconsistent with federal law.” “It seems as though the administration wants to pretend nothing's happening, and one way to pretend nothing's happening is to have marijuana being sold right under their noses in the middle of D.C. and not do anything about it,” he said.
