A common criticism of medical marijuana is how it's dispensed. Why, enemies of the drug like to say, is cannabis sold in shady storefronts by budtenders with tattoos if it's such a lovely and wonderful wonder drug?

The answer is that tattoos are popular — and the Supreme Court believes cannabis is still highly dangerous and medically worthless.

Hard at work while the rest of the federal government takes a break, the nation's war against the plant continued Monday when the high court denied an appeal of the Drug Enforcement Administration's classification of cannabis as no use to the health profession.
