Crack and Powder Cocaine Still Contain Levamisole – and It Still Causes Illness

Some people still get very ill because of cocaine contaminated with levamisole. (It’s a toxic substance for de-worming animals, added by cocaine producers.) Most people doing cocaine do not react, however, people who do can have severe infections or sickness.

  • Most crack/cocaine contains levamisole. You can’t tell if it’s there by looking at it, smelling or tasting.
  • It doesn’t matter how you used the cocaine, or what type it is.

If You Have Any of These Symptoms, Go to the Hospital Emergency Room Immediately
