Black Tar Heroin
Black tar heroin is a free base form of heroin that is sticky like tar or hard like coal. Its dark color is the result of crude processing methods that leave behind impurities. Despite its name, black tar heroin can also be dark orange or dark brown in appearance.
Black tar heroin is a specific type of heroin that is typically less refined and not as pure as normal heroin and therefore cheaper. It is illegal in the United States and sold on the street as chiva, Mexican tar, Mexican mud, black pearl, and more. True to its name, black tar heroin appears sticky and dark in color, unlike other types of heroin that tend to come in the form of a lighter powder. Black tar heroin is typically produced in Mexico before being distributed into the United States.1 Most users will dissolve black tar heroin before injecting it.
