Butyrylcholinesterase is believed to play a role in the body's ability to metabolize the drug cocaine. In 2008 an experimental new drug was discovered for the potential treatment of cocaine abuse and overdose based on the BChE structure. It was shown to remove cocaine from the body 2000 times as fast as the natural form of BChE. Studies in rats have shown that the drug prevented convulsions and death when administered cocaine overdoses.
