Library of Psychedelic Research
If you want to dive deeper after reading the info page, below are some good places to start. They are about the status quo in psychedelic research and about safe use and the potential positive effects.
Fortunately, there are more and more sources describing the positive effects psychedelics can have and how to best ensure those come about (and how to prevent negative experiences and after-effects). Below you can find a selection of both news articles and scientific books and papers. Where possible you can read the source immediately, otherwise, the link leads to a place where the source can be purchased.
Disclaimer: this list by no means attempts to be complete.
You can trust that we have read all these sources and have the information contained in them at our fingertips during sessions. Yet we also want to disperse the information, because we believe that it contains important knowledge that should be as widely available as possible. We guess this is another way of saying: You don’t need us to have a good trip – but if you feel drawn, we’re available.
We’d love for you to let us know through the contact form if you stumble upon a good resource we haven’t mentioned here!

As you can see from the headings below, we have no specific content for other types of psychoactive substances like different types of Ayahuasca, San Pedro, Iboga, DMT, 2-CB or MDA. There is also information available about those; these general sources might be a good place to start.
LSD (d-lysergic acid diethylamide)
Before and After
Test kits available at
We advise taking 5HTP/L-tryptophan for 1 week and eating foods high in anti-oxidants to prevent or at least dampen the infamous ‘Tuesday dip’.
- Drugsenuitgaan.nl (in Dutch)
- you can buy 5HTP at drugstores or vitamin stores like holland&barrett. Use of this supplement is advised against from 2 weeks before an operation and in case of pregnancy. But if you’re pregnant, you’re hopefully not thinking about using anything anyway ;-).
