Pharmacology · Harm reduction
Auf Deutsch lesenEvidence-oriented information on psychoactive substances, interactions and harm reduction.
For understanding and harm reduction. Not individual medical advice.
Network motif from recorded targets · no risk assessment
01 / Combinations
Individual profiles do not explain every combination. Choose two substances or classes and open the existing checker with sources, provenance and uncertainty.
Many notes are class-based. The absence of a warning does not mean a combination is safe.
Interaction checker
The assessment opens in the full checker. This entry point does not display a risk verdict.
02 / Connections
From a substance to its targets and mechanisms. Explore recorded relationships in the knowledge graph and follow them to the relevant profiles.
Open knowledge graph
A map of the information available. Not a complete scientific knowledge base.
Explore the Effect Atlas03 / Go deeper
Editorial context on research, pharmacology and harm reduction — from Synapedia’s English knowledge library.
04 / Substance knowledge
Effects, risks and mechanisms in a shared structure. Profiles vary in depth; missing information remains part of the picture.
All substances
Two profiles side by side: identify differences, compare information and see which questions remain open.
Compare substances05 / How we work
Synapedia connects structured data with editorial context. Sources, provenance and limitations are part of that work.
Read our methodologyStructural quality is not evidence strength. Confidence varies by content and by claim.
Sources and review status are shown where recorded. Automation does not replace expert review.
Information should make risks easier to understand. Specific health concerns need professional support.
06 / People
Who takes responsibility, how the platform is built and what comes next.
