Well there is a federal bill in the works right now for the taxation and legalization of mary jane but it won't pass. Imagine if it did though that would be so funny. Right now in Cali we've got some thing that is going to increase taxes on medical pot and try to legitamize the way the system works a little more, because right now its pretty much wild west shit.
If its just a decriminalization bill, even if it passes, it won't really do anything probably. Weed is decriminalized in west hollywood, but if you don't get pulled over specifically by WHPD, so its CHP or LAPD or whatever, you are screwed anyway. Some sort of thing going on in Denver I think.
