Pot Initiatives Likely To Spark a Battle With the Feds

Former Obama drug official says his old colleagues won;t back down

With measures to legalize pot leading in Washington and Colorado polls, one of the president's former senior drug policy advisers is predicting the initiatives will incite a war between the feds and the states.

"Once these states actually try to implement these laws, we will see an effort by the feds to shut it down," Kevin A. Sabet told NBC News in a report published Sunday. "We can only guess now what exactly that would look like. But the recent U.S. attorney actions against medical marijuana portends an aggressive effort to stop state-sponsored growing and selling at the outset."
