A surge in medical marijuana in California has left communities trying to regulate or ban the drug. This wine country town has welcomed a dispensary as a strong source of tax revenue during the recession.

Peace in Medicine marijuana dispensary is a clean, modern operation in a former auto dealership, and has more registered patients than the town has residents. It could easily be mistaken for a doctor's office, if not for the three security guards and overwhelming skunky smell of pot.

"I guess I had my prejudices that it was going to have bars on the windows and be something very obvious and unappealing to the public," longtime city councilman Larry Robinson said.

Now the dispensary is about to open a second location, next to a Starbucks.

"I'm the luckiest guy in the world to be leading this thing," said Peace in Medicine's operator, Robert Jacob.

In Los Angeles - the marijuana dispensary capital of the country - about 800 dispensaries are estimated to have opened despite a 2007 order halting new pot operations.

The explosion is blamed on a loophole in the City Council's moratorium. Final regulations are still not in place.

The struggle has been linked to the vagueness of the ballot initiative that California voters passed in 1996 legalizing medical use of the drug. The measure makes no mention of how or where the drug can be sold.
