Deschloroketamine
Deschloroketamine is a dissociative research chemical of the arylcyclohexylamine class. Structurally analogous to ketamine but lacking the chlorine substitution on its phenyl ring, it produces dissociative, anesthetic, and hallucinogenic effects. It is reported to be more potent than ketamine with a longer duration of action.1 The substance is primarily available through online research chemical vendors as a designer drug.

Pharmacology
Pharmacodynamics
In experimental receptor assays, deschloroketamine antagonized recombinant human NMDA receptors with activity comparable to ketamine; the S-enantiomer was more potent than the R-enantiomer. Rat experiments also found ketamine-like locomotor stimulation, place preference, and disruption of prepulse inhibition. These animal findings describe hazard-relevant experimental effects and must not be converted into human dose or effect predictions.citation needed
Pharmacokinetics
Human pharmacokinetics remain uncharacterized. After subcutaneous administration in Wistar rats, deschloroketamine reached maximum brain levels at 30 minutes and remained high at 2 hours. Rat studies identified nordeschloroketamine, trans-dihydrodeschloroketamine, and cis- and trans-dihydronordeschloroketamine. Recombinant CYP2B6 can N-demethylate deschloroketamine in vitro, but this does not establish the dominant enzyme or clearance pathway in humans.2
Dangerous
Highest riskThese combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.
Caution
Use cautionThese combinations are not usually physically harmful, but may produce undesirable effects, such as physical discomfort or overstimulation. Extreme use may cause physical health issues. Synergistic effects may be unpredictable. Care should be taken when choosing to use this combination.
Tolerance
Tolerance timelines are rules of thumb, not exact schedules, and vary widely between individuals and use patterns.

Harm Potential
Addiction & Dependence
Psychological
ModerateWith repeated use, deschloroketamine may present a moderate addiction risk, carries meaningful abuse potential, and may lead to psychological dependence. Reports also describe compulsive redosing during use.
Physical
LowWhen addiction develops, cravings and withdrawal effects may occur upon sudden cessation of use, though the severity and nature of physical withdrawal symptoms are not well-characterized.
Toxicity
Chronic frequent use may cause bladder and urinary tract problems similar to those seen with ketamine, including urinary frequency, urgency, pelvic and bladder pain, hematuria, and incontinence; these effects appear to occur to a lesser extent than with ketamine and can be avoided by limiting use to occasional rather than daily or weekly consumption.
Antibacterial properties have been speculated but only minimally investigated. If real, prolonged frequent use could potentially disrupt gut microbiome or affect immune function, though this has not been confirmed as a concern at reasonable low-frequency use levels.
Psychosis Risk
Dissociatives including DCK carry a risk of adverse psychological reactions such as mania, hypomania, delusions, and confusion. Mania is listed as a potential acute cognitive effect. Risk may be elevated when combined with stimulants.
History & Culture
Discovery and Synthesis
Deschloroketamine was first described in a 1966 patent filed by Calvin Stevens at Parke-Davis in Michigan. Stevens, who is also credited with the synthesis of ketamine and phencyclidine, outlined the preparation methods for this structurally related compound.citation needed Despite this early

Legality
International
Deschloroketamine is not listed in the schedules of the 1961, 1971 or 1988 United Nations drug conventions. The UNODC substance record identifies deschloroketamine as a phencyclidine-type new psychoactive substance but does not assign an international scheduling entry; national controls may nevertheless apply.
