One of the tactics Bishop used in his attempts to persuade people to lead healthier lives was to equate addiction with slavery. In this leaflet he describes smoking tobacco and drinking coffee as physical acts of self-poisoning. Bishop’s language mirrors a common fear of the Cold War era: sleeper agents. As in Richard Condon’s The Manchurian Candidate, sleeper agents were individuals brainwashed and used as spies, unaware that their thoughts and actions were under the control of a foreign power. Bishop tried to wake up Americans to the brainwashing effects of tobacco and caffeine advertising, whose power he felt conditioned people to believe in the glamour of their products.
