Like Carl Sagan, another very smart person who enjoyed banging the gong and hitting the bong and was able to make it work, whether in the lab or on the islands. The cultural anthropologist became an avid toker after contracting a disease and using the boo medicinally, at first. She later testified before Congress to legalize the stuff because of the relief she received from smoking weed. Congress said no deal, but gave her the Medal of Freedom after she passed on to her special isle in the sky in 1978. - Margaret Mead
