He's not demented. Jack is retired and actually quite serene in his new job as senior Budtender. He considers himself a gentleman horticulturist and retired "magic carpet" cosmologist. There's nothing backbreaking about being high especially here since he acquires his high by osmosis, in symbiosis with the Universe. His daily routine includes dropping in on the people who populate the planet, catching bits and pieces of their conversations. He's cryptic in his diaries, chronicles and hallucinations but only because his typing can't keep up with his fantasies. "I am the man who wants to know everything and I've had to adapt my way of thinking to that of a chameleon philosophy ready to bear the colors of all tartans."
