Xanax/crack. Cardiac arrest, seizures, loss of effectiveness of xanax, (alprazolam) and more respiratory distress, to mention a few.
Health risk is BAD. Smoking crack Cocaine is really bad for your health. It irritates the lungs and in some cases, can damage them permanently. It raises heart rate, constricts blood vessels, and can cause heart attack & stroke. Can cause sudden overwhelming kidney failure. Can cause seizures & bizarre behavior. Xanax (alprazolam) will not calm any of this down -- will just add to the pharmacological stew. Stop. Now.
