“The American Academy of Otolaryngology-Head and Neck Surgery considers cocaine to be a valuable anesthetic and vasoconstricting agent when used as part of the treatment of a patient by a physician. No other single drug combines the anesthetic and vasoconstricting properties of cocaine.”

The most recent application to the DEA for the license for importing coca leaves was done by John J. Martin, Assistant Administrator.

According to New York Times (1988), “Besides producing the coca flavoring agent for Coca-Cola, Stepan extracts cocaine from the coca leaves, which it sells to Mallinckrodt Inc., a St. Louis pharmaceutical manufacturer that is the only company in the United States licensed to purify the product for medicinal use.”

Also, in 1988, Stephan purchased coca from Peruvian Government corporation, Empresa Nacional de la Coca and shipped to the Maywood plant through ports in New York and New Jersey.
