Ketamine Nasal Spray (Gray-Market & Compounded)
Street names: K nasal spray, Ketamine spray, Compounded ketamine, Special K spray, At-home Spravato
⚡What it does
- Dissociation, euphoria, calm — onset 5–15 min via nasal route
- Marketed for 'depression treatment at home' by telehealth clinics and grey sellers
⚠Key risks
- THE DOSAGE LIE: grey-market sprays rarely state mg/mL accurately — a 'spray' can be anything from a threshold dose to a k-hole; bottles from the same seller vary
- Bladder damage (ketamine cystitis) risk identical to powder — daily spray use makes it easy to use daily
- Dependence creeps fastest with convenient formats; the spray removes every friction point
- Telehealth 'ketamine at home' prescribing has drawn FDA scrutiny and state crackdowns (2024–2025) after adverse events
- Never drive — impairment from a nasal dose lasts 1–3 hours
- Spravato exists ONLY as a clinic-locked REMS program for one reason: monitoring. Any 'at-home Spravato' is a red flag
✚Overdose signs
- Heavy dissociative sedation, unresponsive but eyes open
- Vomiting while impaired
- Slow breathing (rare alone; dangerous with depressants)
