it looks like california is in a position that if they don't legalize pot, they are going to collapse. It's the number1 cash crop and they aren't getting a dime/quarter from it (no pun intended) and it's clear that since it's the number1 cash crop, that cash is going somewhere, mostly to the local california black market AND/OR mexican drug cartels.
They have a war on their southern border that is partly funded by weed money. Take that away and it helps curb the war, then tax it, let non violent tax paying drug offenders out of jail, quit pushing offenders through the courts (money, time), quit having cops waste their time chasing pot, and BAM, california is back on track.
Only thing is though, it would still be illegal federally, so even if they did legalize it, DEA could still come confiscate that tax money. So Governator would need to tell Obama to back off, and let it be a state choice.
