Possession was legal.

Manufacture, sale, and transportation were illegal ... that's plenty of prohibition.

Doctors could prescribe whiskey as "medicine."

Doctors can prescribe cocaine and opiates. Does that prove there's no real War on Drugs?

Low alcohol beer was legal. Law enforcement officers couldn't enter establishments that were serving it.

Not even with probable cause? Have any evidence for that claim?

No it's not, which is why the Libertarians and pot addicts want the same loopholes in order to break the prohibition on pot.

Plenty?

The manufacture, sale, and transportation of marijuana is illegal in California. How's that prohibition workin' out there slim?
