California isn't Colorado. Our legal system is different to Colorado's, and our constitutional protections for citizens' initiatives are apparently far stronger. Every conservative part of California has at one time or another tried to modify, limit or otherwise fuck with mmj here, and our Supreme Court has bitch-slapped every one of them. They will do the same with attempts to derail personal mj cultivation, possession and use by adults if Prop 19 passes.

That said, Prop 19 does permit local gov'ts to INCREASE the minimums allowed, just not to curtail them.
