The new federal crackdown on medical marijuana announced October 7 by the four California U.S. Attorneys sent chills throughout the industry. It was a stunning reversal by the Obama administration. Only two years ago, Deputy U.S. Attorney General David Ogden wrote his infamous "Ogden Memo," announcing that the feds wouldn't bother businesses in compliance with their own state laws. It proved a dose of Miracle-Gro to California, where pot-selling stores have multiplied since voters approved the state's 1996 medical marijuana law. By late last year, California reportedly had more dispensaries than Starbucks outlets.
