Considering Ellen LeMotte's take on

*The Ethics of Opium* from 1924. About halfway through, and it's certainly interesting, with plenty of stats from various countries, both opium producing and non, and also gives figures on users in those countries, both smokers and eaters.

Also takes short detours to give some insight to the trade and use of cocaine and hashish. Anyone else ever taken a dive into the realities of the opium trade and use, either in the past or in the modern day?
