I, too, am generally in favor of the proposal but in addition to, and complementary of, Certified AOD Counselor's comments...The problem, if Prop. 19 passes (and I am one of the "YES" votes!), will be that EVERY city and county in the state will have to make a decision as to whether marijuana can be sold or cultivated or possessed, within their local jurisdiction! That means ALL 58 Counties, PLUS ALL 481 incorporated cities in CA, will have to decide if marijuana is "legal" at a SPECIFIC local level. Some cities will still say no to it, for the revenue that citing people for possessing it, or growing it "illegally" will bring.
It will be interesting to see WHERE in CA, marijuana will be "legal" 1 year after Election Day!
I'm not too sure it will eliminate the black market or criminal element of marijuana cultivation or sales as well. It may in California, but I believe every deliberate Tom, Dick, and Harry from California, not to mention criminal enterprises, will try exporting it to the other 49 states-- and their law enforcement agencies and DA's will be going nuts over this weed explosion from the West. Fed Ex, UPS, and the USPS will be also be going nuts inspecting packages from California-- and making referrals to their local law enforcement.
We're permissive here in this state but they certainly aren't in others-- where even the smallest amount in possession or transportation will land you in the clink (think Nevada and Arizona, for example).
