The state could remove said law. Lol. Prop 19 allows for a market, but that doesn't mean there will be one in most of california. Prop 19 does not remove any law regarding trade as far as I know, unless your county supports cannabis sales, it will still be illegal.
but cultivation and possession will.
if you go to the next county and buy it your county looses the revenue.
of course that is one of the great parts of 19. it does not impose a one size fits all regulation on a population as diverse as california.
it leaves it where it should be in the hands of the communities (as opposed to a central state government)
how much easier is it to effect change at a local level?
ive said it before in smaller counties millages and resolutions pass by ONE VOTE at times!
city council members and county commissioners are outed with a well organized local campaign as opposed to well funded by lobbyists state bureaucrat fat cats who are entrenched.
shit you can take a councilman's seat for a few grand!
