Where Does Black Tar Heroin Come From?

Black tar heroin comes from morphine, a naturally occurring substance that is extracted from the seed pods of the opium poppy plant.

Opium poppy plants are grown across the world, in South America, Central America, Southeast Asia, and Southwest Asia.

Most of the black tar heroin in the United States is trafficked in from Mexico and Columbia.

Creating Black Tar Heroin: Step-By-Step

Black tar heroin is partially synthetic, or man-made. Creating it involves a refining process, which occurs through several steps.

Harvesting Opium

Black tar heroin comes, in part, from morphine. Morphine is refined from opium, a milky fluid that can be extracted from the seeds of the opium poppy plant.

Refining Black Tar Heroin From Morphine

Black tar heroin is the crudest form of heroin. It is cheaper and easier to make than powder forms, because it involves a less extensive refining process.

The process of refining black tar heroin from morphine can vary. Various manufacturing methods can be used to refine morphine, and this can differ between manufacturers.

Once morphine is harvested from raw opium, it may be drawn off and heated with ammonia, further boiled and filtered to create a morphine base.

Producing black tar heroin involves a series of steps that can require the addition of other chemicals such as acetic anhydride, chloroform, and sodium carbonate.
