Levamisole (Cocaine Cut)

Street names: Levamisole, The flesh-rot cut, Cocaine adulterant

Levamisole (Cocaine Cut) — White crystalline powder — indistinguishable from cocaine in a bag (that's the point)

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

Overdose signs

  • (Not an overdose drug) — warning signs: black/purple skin patches, sores that won't heal, persistent infections, fever
