The Entheogen Combination Matrix
The Entheogen Combination Matrix was created by Dr Liam Engel and the Entheogenesis Australis team in collaboration with Psychedelic Research in Science & Medicine (PRISM) and IzWoz art. The combo matrix was also inspired by Tripsit’s Guide to Drug Combinations chart.
The Entheogen Combination Matrix plots commonly consumed psychoactive substances alongside images, scientific and common names of their environmental sources on a graph. The intersection of each axis is coded with the estimated risk of consuming that particular entheogen combination
The Entheogen Combination Matrix is now updated with a flip side! On the reverse of the combo matrix poster, we have now listed short descriptions for each entheogen listed on the matrix axis, as well as information on their psychopharmacology. For the field, We recommend you print out double-sided on an A3 page and laminate it for safe keeping and sharing with your peers.

We hope the Entheogen Combination Matrix will maximise benefits and reduce harms of entheogen combinations, while also advancing understanding of the names and appearances of natural sources of psychoactive substances. We believe that such environmental awareness is key to conservation and sustainability.
