It was the Civil War that primed the nation for rampant drug addiction. So much Opium and Cocaine was used as pain killers for war injuries that it caused a demand for product. Product eventually moved into the civilian sector.
Had we not stopped it, we would have logistical growth of addiction, just as China did.
nice job stopping drug use in society. I have the same comment about stopping drugs by making them illegal 150 years ago as I do now.
