Since I focus on The Germans and their lifestyle I build a few hypothesis. Some are based on their believe that drugs or medication called substances would make them stronger and that most of their violant parts are either highly functional drugged Down or Autists.
There is a human type that is rather short and has also rather short fingers. They are dominant in Central and South America, but also live in Europe. My hypothesis is that that kind of Homo Sapiens is especially vulnerable for creating Down Syndrom when taking drugs.
...And that these guys here for well know that, but most likely noone told their kind of human in South and Central America. Like where already basic literature is missing you could not be bothered mentioning some side effects. The same way you murdered first time E users.

I also assume that there is no scientifc resarch published focusing on human prerequisits to create a drug addiction based on e.g. gene pools or nutritian or social restrictions, for the very same reasons the CIA does not publish their aquired Auschwitz research material on e.g. torture, but is cocky about sending humans to Egypt or Iraq for questioning, before Guantanmo was build using sleep restriction and waterbaording.
