I'll look when I'm not at work. The numbers aren't easy because opiates were used in many different ways. Surely you will not deny that the majority of the population TOOK cocaine and or heroin. They sold them like candy of the shelves. Said to cure toothaches, impotence, depression, headaches, appetite suppressants, ect, ect. They were the miracle drugs. House wives, and working men were getting to the point of NEEDING their cocaine or heroine powder.
1903 was when heroin or opiate addiction was at it's worst in America. FAR worse than it is today.
