Obama is only 1 in three groups of lawmakers. In regards to marijuana policy congress has much more influence than the president. There will be no change unless it is through congress and judiciary first. The drug companies spend massive amounts of money in order to keep their business running as usual. Unless we get some decent, honest politicians(becoming an oxymoron) the freedoms and liberties intially intended for us will never be achieved. Frankly, the only change I think we will see is the value of the dollar.
