Some of my finest hours have been spent sitting on my back verandah, smoking hemp and observing as far as the eye can see.

~ Thomas Jefferson ~

Snope's say this quote isn't true or proven, howvever there are various diary entries by Thomas Jefferson where he refers to sorting out of the male and female hemp plants.  This plant has so many uses indeed and there is no reason why he wouldn't have a choof if he was a smoker.   His sorting of the plants is key to this statement being seen as true.
