Ketamine is a powerful medication originally developed as an anesthetic, but it is now used for a variety of purposes, both medical and recreational. Its effects depend heavily on the dose, method of administration, and context in which it's used.
What Is Ketamine?
Medical Uses:
General anesthesia (especially in emergency or battlefield settings)
Off-label use for treatment-resistant depression, anxiety, PTSD, and chronic pain
Sometimes used in veterinary medicine
Recreational Use:
Sometimes taken for its dissociative, euphoric, or hallucinogenic effects
High doses can lead to a state known as a "K-hole"an intense dissociative experience

Common in hospitals and ketamine clinics
Used for anesthesia or depression treatment
Rapid onset; effects within minutes
2. Intramuscular (IM) Injection

3. Intranasal (Nasal Spray)
Approved version: Spravato (esketamine) for depression
