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.
Lysergic acid diethylamide (LSD) is a semi-synthetic serotonergic psychedelic with high affinity for 5-HT2A, 5-HT1A, and several dopaminergic receptors. It produces profound alterations in perception, cognition, and mood at microgram doses.
Psilocybin is a naturally occurring tryptamine psychedelic prodrug found in many fungal species, converted in the body to psilocin—a potent 5-HT2A agonist. Clinical trials support its therapeutic potential in depression, end-of-life anxiety, and addiction.
The Synapedia Comparison Tool presents two psychoactive substances side by side — comparing pharmacological class, mechanisms of action, receptor profiles, and risk ratings. Similarities and differences become immediately visible.
