Norshroom, then and now
From 2001 to 2020 this address was NorShroom, a Norwegian community built around Psilocybe semilanceata, the liberty cap that grows wild in Norwegian pastures. Old links to its liberty cap page still lead to our guide to the species.
Today Norshroom is an English-language news and reference desk for readers in the United States, where psilocybin law is changing faster than anywhere else. We're not connected to the original NorShroom team. Who runs Norshroom.
