Summary
3-MeO-PCMo (4-[1-(3-methoxyphenyl)cyclohexyl]morpholine) is a new morpholine analogue of 3-MeO-PCP. It is a dissociative NMDA receptor antagonist, sigma receptor agonist and anesthetic drug of the arylcyclohexylamine chemical class with a potency of less than 1/10th of that of 3-MeO-PCP. This compound induces a state referred to as "dissociative anesthesia" when ingested and is therefore used as a recreational drug.

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Pattern inferred from dissociative-class use; high uncertainty due to sparse PCMo-specific data. Many user reports suggest meaningful cross-tolerance within arylcyclohexylamines; long spacing between sessions (2–6 weeks) helps restore sensitivity.
