Yes, it certainly did. Thanks for reminding those who forgot about that or didn't know .
I was focusing in on the patent medicine side, because I brought up the PURE FOOD & DRUG ACTS. But, yes, doctors and the general public, who bought heroin, morphine, and opiates over the counter, addicted many poor souls, who thought that they were " curing " something or other.They weren't " cured " ; however, they certainly did become addicts, or killed themselves or others.
The "morphine" solders that came mostly out of the south constituted approx 20% of the southern civil war vets. They even carried their "kits" in a bag, the name of which escapes me but, it was a very serious problem.
I have to correct one point. It was the Union soldiers that were mostly affected. The South could not afford the use of morphine except for amputations.
