And now, for something completely different. Peter Hecht reports in the SacBee:

The Canna Care medical marijuana dispensary has a truck driving around Sacramento with a sign telling people to vote "no" on the state ballot initiative that would legalize pot for recreational use.

George Mull, a lawyer for several Northern California pot shops, is fighting Proposition 19 on claims it threatens protections put in place for medical pot users with the 1996 passage of California's medical marijuana law.

And a Humboldt County dispensary operator complains that the new pot measure simply isn't needed. "They say they're legalizing marijuana," said Stephen Gasparas, who runs the iCenter pot dispensary in Arcata. "It's already legal. All they're doing is taxing it."

California's landmark initiative to legalize marijuana use for adults over 21 and permit local governments to tax retail pot sales is backed - and bankrolled - by leaders in California's medical cannabis movement.

And yet some of its more stubborn opposition comes from a vocal segment of the same community who worry their dispensary operations may be negatively affected.

On a more predictable note, six former "drug czars" from both Republican and Democratic administrations have this LA Times op-ed opposing the marijuana legalization proposition.  Politics makes strange bedfellows, as the saying goes.  Doug Berman at SL&P has this post on the op-ed.
