an artificial arm, metal teeth, electronic eyes: these are the 3 stigmata of Palmer Eldritch
The 3 Stigmata of Palmer Eldritch by Philip K. Dick
Earth is so warm as to be mostly inhabitable. the world government (U.N.) is drafting many to colonize the solar system planets and moons. the conditions for the colonists are brutal: intense physical labor, crowded conditions, and hardly no material goods. thank the goddess for CAN-D!
CAN-D is a drug that makes the user enter the miniature world of the Perky Pat Layouts(tm); these tiny setups, with their miniature dolls, furniture, and goods are the only escape for the colonists. Perky Pat Layouts(tm) are sold exclusively by PP Layouts (Ltd); PP Layouts (Ltd) also (secretly) controls the supply of CAN-D.
Palmer Eldritch, presumed dead, when rescued from his travels past Pluto brings CHEW-Z a drug he claims is different and much more powerful than CAN-D.
