Well, that didn't take long.

Federal agents executed search warrants at three medical marijuana dispensaries on Wednesday as part of a broad investigation into marijuana trafficking in San Francisco, setting off fears among medical marijuana advocates that a federal crackdown on the drug's use by sick people was beginning.

About 20 residences, businesses and growing sites were also searched, leading to multiple arrests, a law enforcement official said. Agents outside a club in the Ingleside neighborhood spent much of the afternoon dragging scores of leafy marijuana plants into an alley and stuffing them into plastic bags.

[...]

The raids and arrests were the first large-scale actions against marijuana clubs and providers since the Supreme Court upheld federal authority over marijuana on June 6, even in states like California, where its use for medicinal purposes has been legal since 1996. The raids involved agents from federal agencies including the Drug Enforcement Administration, the Internal Revenue Service and the Secret Service.

"We will not turn a blind eye to serious and flagrant disregard of federal law," Gordon Taylor, an assistant special agent in charge of Drug Enforcement Administration office in Sacramento, said in a statement. "There may be those who think we can disregard the court and Congress. D.E.A. will not be among them."

More delightful details here.

I, for one, am glad that the D.E.A. is on the scene to show everyone who's in charge. Crystal meth is a scourge all over America, there's even an apparent resurgence in the popularity of crack cocaine, but the jackbooted thugs brave souls at the D.E.A. are making sure that sick Californians can't get their medicine. Well done, folks.
