Ketamine is recognized internationally as an essential injectable anaesthetic and is listed on the World Health Organization’s Model List of Essential Medicines for use in health systems; this status underpins its routine authorization and clinical use in many countries for anaesthesia and emergency medicine. [1]WHO Model List of Essential Medicines.
Under Yemen’s Law on Control and Illicit Trafficking and Abuse of Narcotics and Psychotropic Substances, controlled drugs may be imported, registered and used for medical purposes when authorized by law and in compliance with registration/notification requirements; this legal framework provides the pathway by which anesthetic agents such as ketamine would be lawfully used within hospitals and licensed facilities in Yemen, subject to ministry/regulatory controls. There is no public, centralized Yemeni medicines registry published online that documents a national reimbursement schedule for ketamine for psychiatric (off‑label) indications; in practice in low‑resource and conflict‑affected settings (including Yemen), ketamine’s primary and documented use is for procedural anesthesia and emergency care rather than reimbursed psychiatric administration.

Practical implications: (1) Ketamine is lawfully used in clinical/operative contexts when properly procured and authorized by health authorities; (2) there is no published evidence of a national reimbursement program for ketamine when used off‑label for psychiatric indications in Yemen; (3) any use outside authorized medical settings (recreational possession, unlicensed clinics) would be contrary to Yemeni narcotics law.
