Cocaine sold in the street is often mixed with any number of “cuts” to dilute and make more of it, usually for financial reasons. Some of the most common cocaine cuts include: local anesthetics such as benzocaine, lidocaine and procaine; synergistic stimulants such as caffeine, ephedrine, amphetamine, methamphetamine, and many more inert ingredients or mundane cuts such as cornstarch, sugars, creatine, inositol, baking soda, acetaminophen, aspirin, glucose and lactose. Certain non-stimulant pharmaceuticals are also used as cut to increase the potency of cocaine. Unfortunately, a new development secondary to the opioid epidemic is cutting cocaine with highly dangerous synthetic opioid cuts such as fentanyl and carfentanyl. Synthetic opioid cuts are the most dangerous of all as they carry the possibility of a lethal overdose in an opioid naïve cocaine user.
