California made legal?

California was the first to make medicinal marijuana legal ('96), and now those who pushed for and maintained this exceptional social project are pushing even further in order to obtain an economic boon, and to cut down on crime.
An estimated 60-70% (their numbers, not mine) of the Drug Gang's funding comes from pot, and the logic goes 'remove their income, mitigate the violence'. Legalising has the added perk of potentially netting the 'billions' of dollars (1.5 billion $ at the articles estimate) to help fund state activities.
People are coming around to this line of thought because of a growing perception that 'the war on drugs' has failed miserably. California state Assemblyman Tom Ammiano says that "Prohibition is Chaos, Regulation is Control."
