Are there any great books out there that cover the history of drug production and distribution and its prevalence in societies? In ancient Greece, Rome or Egypt, China or India? The middle ages, 18th centuries, etc.?
As well, was it necessarily always illegal? Were people relatively more accepting of drugs throughout history than in the modern day? (I'm talking more the widely illegal forms of hallucinogens or narcotics, not drugs like alcohol or caffeine or nicotine, so there's no confusion.)
Did most people even know such narcotic substances existed before the modern day, or what their consequences to a person's well being may be?
If so, was crime (not drug trafficking obviously, if it was legal then there was no crime associated with that. I mean like murder rates and such) associated with such civilizations and drugs also far lower, or deaths from overdose or rival drug producers higher or at the same rate as in the modern day?
The subreddit has an FAQ section about drugs. Most of the answers there are by /u/Lukeintheskywith. "Narcotics" is a narrower category than "illegal drugs", but both have fluctuated over time.
