Re:don't really know the answer but,

maybe in the minds of the all powerful DEA they rake it in.Think of all the properties they confiscate throughout the year.That has to be one of the incentives to keep these Draconian laws in effect.

The reason that cali is worth that much in bud is because they are going by what it costs "street value" right now. If it were legal that number would be a fraction of that. That means everyone who sells for profit would be losing out. Putting our mom and pop smaller grow ops out of business. Replacing our bud with marlboro og kush and Newport menthol bubba. Do you really wanna smoke that? Does it suck that we have to live in fear? HELL YEAH! But do I wanna lose my income? NOPE! Decriminalization for small amounts would be cool, but full legalization is crazy.
