The difference in the dam instance was that pure heroin was being sold as cocaine, not adulterated heroin being sold as just heroin. The guy in Holland almost certainly knew what he was selling and for some reason sold it to tourists as cocaine. What would possess someone to do such a thing idk, maybe a very desperate need for cash but who knows.
If heroin addicts were just given heroin people wouldn’t die, they also wouldn’t be broke, stealing, and ostracised from the community to the degree they are. No changes to any laws required, we even give a few hundred users in this country pharmaceutical grade heroin. I remember reading an article about a doctor in Liverpool who ran a clinic and in the early 80’s he could prescribe them heroin. In around 4 years he never had one patient die and he had somewhere in the region of 400 patients. He left around the time the government put an end to this and when he returned to the area about 10 years later, about 1/3rd of his original patients were now dead. I may have the numbers wrong but I’ll try find the article.
