As a counterpoint, most or all of that is also true of the majority of entheogens with deep cultural roots, like Ayahuasca. Amanita Muscaria is another abundant mushroom that is even toxic if prepared incorrectly, and yet has a long history of use in shamanistic cultures(though not in viking culture, as is widely misbelieved). I'm not going to speculate much about the extent of psilocybe semilanceata usage in Germanic/Sami cultural history, other than to say that it would likely have become taboo due to Christianity, and therefore went unrecorded.
