Civilization A has a fixed population; so they need armies from outside sources to protect themselves. After many years of reign over a nearby civilization (Civilization B) to supply armies for A, several uprisings have cut into the population of A. A therefore decides to impregnate B with a religion where certain "signs" or "prophecies" would make B act predictably if A forced these signs. Control from A was covertly maintained by this religious impregnation and drugging the city's water supply.

What drug would A use to force chemical dependency on B; so they don't just leave B?

Drug specifications:

  • Must be water miscible
  • Must induce mild torpor
  • Must induce mild euphoria
  • Must be effective at low concentrations
  • Must maintain effectiveness after repeat exposure

Answers will be evaluated by which drug has the largest effect while going unnoticed by the user. (e.g. drugs with few side-effects will be favorable to drugs with severe or many side-effects)
Bonus points for drugs which include other qualities to help make users impressionable.

    $\begingroup$ I still think this is too broad/sounds like idea generation. Also something to consider...how would you define the criteria for an answer to be accepted? I had an idea for a clever answer: dihydrogen monoxide. City B would be completely chemically dependent on it, and if there was none of it elsewhere, they couldn't leave. And as you imply, City A already has control of the water supply. But, I doubt this is the type of answer you're looking for. $\endgroup$ – Seth Aug 13 '15 at 17:05
