O-PCP Stats & Data

Nomenclature and chemistry: IsomerDesign/PIHKAL-info lists this compound under 2′-Oxo‑PCP with synonyms 2‑Keto‑PCP and the IUPAC name 2‑Phenyl‑2‑(piperidin‑1‑yl)cyclohexan‑1‑one; this is the same entity often sold as O‑PCP. Early public discussion threads (May–June 2025) on Bluelight and Reddit confirm recent market appearance and repeated advice to confirm identity by GC–MS/FT‑IR due to confusion with O‑PCPr or O‑PCE. Mislabelled dissociatives are a documented drug‑checking problem; don’t assume label accuracy. Effects appear dissociative with a shorter plateau than PCP and variable sedation; users warn of a ‘clear‑headed’ window at low doses that fosters redosing. Motor incoordination and analgesia increase accident risk; have a sober sitter, avoid heights/water, and do not drive until fully baseline the next day. Combining with alcohol/benzodiazepines or opioids substantially increases vomiting/aspiration and respiratory depression risk; if someone is unresponsive, place them in the recovery position and call emergency services. Tramadol should be avoided due to seizure and serotonin‑toxicity risk; other serotonergic mixes (MAOI/SSRI/SNRI) are of uncertain safety — best avoided until real data exist. Dissociatives can precipitate panic, derealisation, mania, and psychosis in susceptible individuals; screen your set/setting, keep doses low, and avoid if you have a psychosis or seizure history. For dosing precision, volumetric dosing (e.g., 10 mg/mL in PG or ethanol/water) reduces milligram‑scale error; start with 1–2 mg allergy tests separated by at least 24 h. For IM use, only inject fully dissolved, filtered, sterile solutions; non‑sterile injection risks abscesses and systemic infection. Frequent or high‑dose dissociative use is linked to tolerance and dependence; bladder toxicity is well‑documented for ketamine, but is uncharacterised for O‑PCP — still, watch for urinary symptoms and reduce frequency. Drug checking at a professional service (FT‑IR/GC–MS) is strongly recommended whenever possible; reagent kits alone cannot distinguish close analogues.
