Levamisole in the cocaine

Levamisole is an anthelminthic and immunomodulator discovered at Janssen Pharmaceutica in 1966.

Levamisole has been used in humans to treat parasitic worm infections, and has been studied in combination with other forms of chemotherapy for colon cancer, melanoma, and head and neck cancer.

The drug was withdrawn from the U.S. and Canadian markets in 2000 and 2003 respectively, due to the risk of serious side effects, including a significant weakening of the immune system called agramulocytosis.

Currently, levamisole remains in veterinary use as a dewormer for livestock.

According to the Department of Justice, some 70 percent of cocaine (most of it distributed in and around New York and L.A.) is cut with levamisole.

Unlike most cuts — usually inert or relatively harmless substances like the B vitamin inositol, which are added by lower-level dealers looking to stretch supplies — levamisole appears to be added to cocaine from the outset, in the countries of origin. The substance has been found in various concentrations in cocaine analyzed in countries around the world, from Switzerland to Australia.

Levamisole is cheap, widely available and seems to have the right look, taste and melting point to go unnoticed by cocaine users, which may alone account for its popularity.
