Rust
Also known as mexican rust or mexican mud or mexican tar; very impure form of injectable heroin. The drug is often an unorganized mix of opiate plant-based substances. The drugs derived typically go uncleaned due to the harm water can do to the active ingredient diacetylmorphine (the agent that gets the user high). The substance is extremely thick by injectable substance standards, and often causes veins to explode during injection. Rust was first spotted in Ecuador, but is believed to have been first produced in Mexico, due to the combination of substances in the drug being native only to the Mexican swamps. Ciudad Juárez, Mexico is the leading exporter of rust, at about 65% of the entire market. Second is São Paulo , Brazil, with around 17% of the market. Rust is sold exclusively in injectable form, and is sold by the gram. Where as high-quality heroin sells for about $200/gram, rust sells for about $55/gram.
