2-FDCK exhibits slower hepatic metabolism than ketamine with an in vitro microsomal half-life of approximately 69 minutes, resulting in longer-lasting subjective effects. Users report a more analytical, less warm dissociation compared to ketamine, with clearer headspace but pronounced motor incoordination. Oral bioavailability appears higher than ketamine, with many users finding oral dosing equally effective to insufflation. The substance produces less nasal irritation than ketamine but saline rinses remain advisable. Reaching a full dissociative state requires higher doses compared to ketamine.
