I recently moved to Europe and am getting involved with the community of researchers and activists over here. Does anybody know whether any country in Europe has a history of psychedelic psychotherapy similar to the US, in which thousands of mental health professionals have used psychedelics in their practice over the past 5 decades? I am particularly interested in places like the Netherlands where some psychedelics are legal or very decriminalized. The like-minded Dutchies who I've talked to so far do not seem to know much about this so that got me wondering whether it existed at all on this side of the pond?
