This page is educational. It is not medical, legal or professional advice, and I am not a physician or an attorney. I gathered this information from published harm reduction organizations, medical and legal sources, and my own training and experience, and I may have made mistakes. You are responsible for confirming anything here before you act on it, with a qualified medical provider and, for questions of law, an attorney. Laws and knowledge about psychedelics change quickly, and some of what is written here may have changed since the date above. Nothing here encourages anyone to break the law. It exists to reduce harm for people who will make their own choices. I do my best to keep up with current law and research, but I cannot promise that anything here is current or complete.
It is advisable to meet with a psychedelic-informed physician for an assessment before using any psychedelic or related substance.
Where this information came from: Each document on this page names its own sources. As with any fact you meet on social media, do your own due diligence to check it for accuracy. Updates coming: These documents are being updated to catch up with the latest research, and the revised versions will be posted soon.
Harm reduction begins with the world as it is. Adults use psychedelics in clinics, in ceremony, among friends and alone, and the people who come through best are the ones who were best informed. These pages hold what I have gathered, so that anyone can prepare with open eyes and decide for themselves.
