This was not one shakedown among many. This was the only game in town; it dwarfed the illegal alcohol and prostitution industries. This was not simply charging a handful of wholesalers and a couple of opium dens. Officials taxed every level of the drug business from the growers, to the buyers, to the chemists and the traffickers. They taxed in cash and they taxed in drugs. And they created an entire state-level police force in order to do so. A lot of the money went into private accounts, but at least some was spent on public works.
