While I like the savings in law enforcement, court resources, and the lessening of people's lives being ruined by the draconian war on drugs laws, my main concern is getting the industrial hemp, like Canada, legal here in California.
Canadian hemp farming history so far:

The State legislature has approved hemp growth a few times but the Governor veto pen killed it a few times.
Maybe if Prop 19 passes and Jerry Brown wins it will open a door.
