Guess Newt Gingrich forgot about marijuana's American history...

"Hemp is of first necessity to the wealth & protection of the country."
~ Thomas Jefferson, U.S. President quote on Hemp

"Make the most of the Indian hemp seed, and sow it everywhere!"
~ George Washington in a note to his gardener

"If a law is unjust, a man is not only right to disobey it, he is obligated to do so."
~ Thomas Jefferson
