Summary
Developed as an incapacitating chemical weapon; a single dose of approximately 0.2-0.3 mg intramuscularly can incapacitate for up to 10 days. Physostigmine is the preferred medical countermeasure but requires repeated administration. Volunteer studies and civilian exposures reported lingering mood and cognitive disturbances for months.

| Intramuscular | 1-2 hrs | 24-72 hrs | 96-240 hrs |
Effect Profile
Scores (1–10) curated from multiple sources:
- Effect keyword matching from PsychonautWiki catalog
- Weighted by importance: core (×3), major (×2), minor (×1)
Low visuals, body load, and headspace
Tolerance
Tolerance Decay
No systematic data on tolerance. Given the prolonged single‑exposure intoxication and absence of repeated recreational use, practical tolerance build is unlikely to be characterized. Conservatively assume at least several weeks before baseline cognition and cholinergic tone normalize after severe intoxication.
