The situation, like all dodgy situations in the polity, had been worked out in enormous detail. Crude compounds that could stop your heart or scar your liver clearly damaged life expectancy, so their use drew stiff medical penalties. Drugs that warped cognitive processes in tiny microgram quantities did very little metabolic damage, so they were mostly tolerated. The polity was a medical-industrial complex, a drug-soaked society. The polity saw no appeal whatever in any primitive mythos of a natural drug-free existence. The neurochemical battle with senility had placed large and powerful segments of the voting populace into permanently altered states.
