Carl Sagan, astronomer/visionary, was a stoner! I have recently come to know the wonders that are the ideas of Sagan but I’m very intrigued with the ideas that came into this man’s head while tripping. His penname, Mr. X allowed him to contribute to Marijuana Reconsidered, a writing about the lighter side of being high. I would love to read his books sometime. Has anyone else had the pleasure?
