Obama talked about legalization yesterday

What you’re seeing now is Colorado, Washington, through state referenda, they’re experimenting with legal marijuana.  The position of my administration has been, we still have federal laws that classify marijuana as an illegal substance.  But, we’re not going to spend a lot of federal resources trying to turn back decisions that have been made on the state level on this issue.  My suspicion is that you’re going to see other states start looking at this. — President Obama on YouTube yesterday
