⚡What it does
- No recreational effect — veterinary dewormer added to bulk cocaine
⚠Key risks
- THE SIGNATURE: levamisole-contaminated cocaine causes agranulocytosis (immune collapse) and skin necrosis — black rotting earlobes, cheeks, limbs documented across the US/EU
- Found in up to 70–80% of seized cocaine in peak years (it passes 'taste/numb' tests and adds stimulant heft)
- Purpura and ear-rot cases cluster — drug-checking services flag it
- Treatment: stop exposure; the immune damage usually reverses in weeks
