The Feds agreed to stop raiding clubs in Cali, but one just got raided recently right after they said that.
To me growing buds is like brewing beer. Different methods create different flavors, and buzz's. Sure if MJ was legalized corporations would sell it, but small brewers make great beer and do very well, even though Budweiser (piss imo) is around.
Plus mass produced always sucks compared to small batches that have more care put into them. Prices may drop, but you will be able to grow and sell with immunity.
As far as Obama is concerned. He said everything he thought he needed to get himself elected. It's not a surprise that a Politician is going back on his word, it's been going on for years. I'm more concerned about the "New World Order", socialism and globalization. Wait until we have one world bank, currency, IRS etc.. Capitalism will be dead, and only a handfull of the wealthiest bankers will run the world.
