2-Methyl-AP-237, often shortened to 2-MAP, is a synthetic acyl-piperazine opioid. International control and early-warning documents describe it as a mu-opioid receptor agonist with opioid-like toxicity, while human pharmacology remains poorly characterised. Forensic reports and fatal intoxications show that real-world exposure occurs, but they do not establish a safe dose or therapeutic window. The main harm-reduction message is respiratory depression: sedation, loss of consciousness and death are especially plausible when potency is uncertain or when combined with benzodiazepines, alcohol, GHB/GBL, gabapentinoids or other opioids.

Scientific interpretation
Why is this substance flagged?
This substance is flagged because structural-chemical features indicate opioid-like μ-receptor activity. Combination with other CNS depressants can be life-threatening even at low amounts. No validated human data exist — the risk profile is entirely class-based.
No validated human data exist for this substance. The risk profile is extrapolated from class characteristics. Structural-chemical features may hint at possible mechanisms but do not substitute for substance-specific preclinical or clinical data.
Class-based — no substance-specific primary literature
Where does this assessment come from?
Known — structure-based
Derived from chemical class (morphinan opioid) and in-vitro data on structurally related compounds.
Suspected — class-based
Extrapolated from known opioid profile: μ-receptor agonism, respiratory depression, tolerance development.
Unknown — no human data
Pharmacokinetics, safe dose range, interaction profile and long-term effects in humans are not established.
Deep-dive intelligence
Community reports and forum discussions exist for this substance. Synapedia treats these as monitoring signals, not verified human data. Reports may be confounded by tolerance, polydrug use and unverified product identities.
Community reports are uncontrolled. It often remains unclear:
Synapedia documents community signals but does not derive dose ranges or equivalences from them.
