A crackball (Not to be confused with a speedball) is when you combine
Crack or Cocaine with Heroin. Usually combined to make
Crack or Cocaine smoother or stay awake during Heroin.
Crack is cardiotoxic (bad for the heart), causes brain damage, and Heroin can stop your breathing. If you survive a Crackball, the high is intense. Sometimes done by snorting Cocaine HCl and injecting Heroin or smoking freebase
Crack and smoking Heroin. It can also be done by dissolving Crack and Heroin in DMSO and putting it on your skin (your skin will absorb it and you will get high).
