It may be sniffed into the nose (snorted), smoked, or injected IV. Occasionally, it is combined with heroin and injected ("speedball"). Cocaine purchased on the street may contain adulterant drugs such as lidocaine or benzocaine (Anesthetics, Local) or stimulants such as caffeine, methamphetamine (Amphetamines), ephedrine (Pseudoephedrine, Phenylephrine, and other Decongestants), and phencyclidine. Most illicit cocaine in the United States is adulterated with levamisole, an antiparasitic drug that can cause agranulocytosis and leukocytoclastic vasculitis.
