In my now 5 years long period of drug use, I have tested and abused a LARGE variety of substances, ranging from psychedelics to opiates and all sorts of stimulants and niche drugs. But there is a class that stuck to me as the most profound in nature; dissociatives.

Summary
2'-Oxo-PCM (also known as deschloroketamine, O-PCM, DXE, and DCK) is a lesser-known novel dissociative substance of the arylcyclohexylamine class that produces dissociative, anesthetic and hallucinogenic effects when administered.
Perspectives
“This stuff is great. New favorite drug mayhaps, it is a beautiful colorful adventure space like MXE, where I can to a degree create a world of my own design. This is what Iβve been pursuing through psychonautics all this time, this is what Iβve pursued my entire life. I feel like with more trials and more focused meditation I can totally control this to an omnipotent degree.”

Effects
Aggregated from 12 single-substance Erowid experience reports; 19 Erowid reports where another drug was taken too are left out
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.
Too few reports for bars: these effects come from 12 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Also reported in combinations. In the 19 Deschloroketamine reports where another drug was taken too, 0 mention hospital, emergency services or an overdose, 0 a seizure and 3 psychosis (too few reports for percentages). In the 12 single-substance reports: 2, 0 and 1. These are not in the figures above: they cannot be put down to Deschloroketamine alone, and a mention is not always something that happened to the writer.

Deschloroketamine... Kind of disappointed. Not the real deal, sadly. After being unable to procure real ketamine for almost a decade, I decided to give this a shot.
Substance: Deschloroketamine (2Β-Oxo-PCM, DCK) Dose: 15mg, 30mg (Separate Occasions) R.O.A: Oral Person: 21/M, Height: 5Β9, Weight: 8 stone (112 lbs) Setting: My Bedroom/student house, London, Night time.
I took live notes during this one. They are incoherent. You can read them here: [url deleted / text pasted at end of report] I tried to incorporate them into the report as best I could but a good chunk of them I just don't remember and a lot of it just isn't even words.
PREVIOUS EXPERIENCE WITH DRUGS: Weed, alcohol, cocaine, amphetamines, methamphetamine, MDMA, Etizolam, Xanax, Modafinil. INTRO: For a long time I wanted to try and explore psychedelic drugs like LSD, something that would give me the ΒeyesΒ to see reality in a completely different manner, though I always felt scared of...
Context Deschlorketamine (nasal spray), Weed (inhaled) Date - 6.10.2021 Male, 19, 75kg Weed user on weekly basis Previous experiences - 1P-LSD, 1cP-LSD, 2C-C, 2-FDCK, 3-MMC, N-Ethyl-hexedrone, N-Ethyl-pentedrone, Psylocibin mushrooms, Deschlorketamine Had a few experiences with dissociatives, but only light doses, neve...
[Erowid Note: The dose described in this report is very high, potentially beyond Erowid's 'heavy' range, and could pose serious health risks or result in unwanted, extreme effects.
I have found Deschloroketamine to be one of the most versatile substances that I have worked with to date. And it works in a way that many other things do not, simply put, it works very well. As we are all aware, every person will undoubtedly have a different experience with this molecule.

Age: 26 Weight: 130 lbs Dosage: 600 mg intranasal Setting: My house Preface: So of course I was super excited when I first saw this compound on the market. This was the first brominated arylcyclohexylamine to hit the market, and its activity would help us answer some questions about the role of different halogens on th...
510 MG OF DESCHLOROKETAMINE, A MILLIGRAM SCALE, A RECTAL SYRINGE... OK here is the report: It began with a miracle of modern service! I had ordered 500mg O-PCM with a vendor and had opted for a mail service.

Sleep was weird. It felt like I didnβt sleep at all. I had vividly realistic dreams, not lucid dreams however, it was like living out movies, being directed by fate and puppet strings and the hand of god, to perform the most mundane tasks in what bordered onβ¦
I don't have much trouble falling asleep, and when I wake up (around 9 hours later, having slept longer than I normally do), I feel quite refreshed and happy. All-around, I'm really happy with my experience with this substance, and can now understand whyβ¦
