What contrary experience of the USA in the 1800s?

As I've pointed out to you: "the rate of opiate addiction in America increased throughout the nineteenth century, from not more than 0.72 addicts per thousand persons before 1842 to a maximum of 4.59 per thousand in the 1890s; thereafter the rate began a sustained decline."

As I've pointed out to you: "the rate of opiate addiction in America increased throughout the nineteenth century, from not more than 0.72 addicts per thousand persons before 1842 to a maximum of 4.59 per thousand in the 1890s; thereafter the rate began a sustained decline."

And as I probably pointed out to you, anyone who claims to have such records is a liar. Nobody was keeping records of addicts in 1842. The East India trading company *WAS* keeping track of their opium imports to China, and that's why *those* records are valid.

You don't have any real data from that time period.
