2-FDCK (2-Fluorodeschloroketamine) in crystal form is a dissociative anesthetic that acts as a structural analog of ketamine. In the recreational market, it is often sold as large, “sea salt-like” white or transparent crystals, which are frequently perceived (sometimes incorrectly) as being higher purity than the powder form.

Chemical Nature & Effects
2-FDCK replaces the chlorine atom in ketamine with a fluorine atom. This small change alters how the body processes the substance.
-
Potency & Duration: 2-FDCK is generally considered to be slightly less potent than ketamine by weight (often requiring 10–20% higher doses), but it has a longer duration. A typical experience lasts 2 to 4 hours, whereas ketamine usually fades after 60 minutes.
-
Oral Bioavailability: Unlike traditional ketamine, which is largely destroyed by the stomach, 2-FDCK is highly effective when swallowed. This makes the “oral” route a popular alternative to snorting, though it extends the duration of effects even further.
-
The “Hole”: It is possible to reach a “K-hole” (total dissociation) with 2-FDCK, but users often report it feels “colder” or more “clinical” than the traditional ketamine experience.
