Great comeback. You threw out the Constitutional Republic bit. Now, I can read the Constitution to you line by line and I am 100% sure we won't come across any mention of smoking.
Oh, are you talking about the "life, liberty, and pursuit of happiness" rights? If you are, then let me get out my copy of the Declaration of Independence so we can go over that document also.
It's my LIFE, and I take the LIBERTY to smoke because it brings me HAPPINESS!
