Synapedia is an independent knowledge project about psychoactive substances and harm reduction. If the platform helps you learn something new, you can support its development.
Every bit helps keep the project alive.
Explore the full body of knowledge on psychoactive substances as an interactive network. The Synapedia Knowledge Graph visualises the relationships between substances, receptors, mechanisms of action, interactions and scientific articles – making complex pharmacological connections immediately visible.
Use the graph to explore interactions between substances, or visit the Interaction Checker for detailed risk analyses. Compare substances with the Comparison Tool.
Zoom & navigate: Scroll to zoom and drag the background to pan. On mobile, use two fingers to zoom.
Select a node: Click a node to highlight its connections and display details in the sidebar. The recommendation engine automatically surfaces similar substances and relevant comparisons.
Search & filter: Use the search bar to jump directly to a substance or receptor. Filter by node type or substance class.
Safety mode: Enable safety mode to show only critical substance interactions – edges are highlighted by risk level.
Share: Share a specific view via the share button in the detail panel. The link preserves the current focus and mode.
The knowledge graph is based on scientific sources and structured data from the Synapedia database. It is for educational purposes only and does not contain consumption recommendations. All information on risks and interactions does not constitute medical advice.
