In a move marijuana advocates hailed as an historic shift, the Obama administration on Thursday began giving U.S. states wide leeway to experiment with pot legalization
Attorney General Eric Holder told the governors of Colorado and Washington Thursday that the Justice Department would not -- at least for now -- block their states from implementing regimes to tax, regulate, and sell marijuana.
An analysis from pro-medical marijuana group Americans For Safe Access found that President Barack Obama's administration has spent nearly $300 million on combatting medical marijuana in states that have legalized the drug.
