Black tar heroin is an illegal drug from the poppy plant’s resin. It is typically darker in color than other heroin types and has a sticky, tar-like consistency. Because of its appearance and texture, black tar heroin is sometimes called “black tar,” “black rock,” or “tar heroin.”

The drug is typically sold as a black, sticky substance that can be smoked or injected. It also has a distinct smell similar to vinegar, licorice, or shoe polish. The smell can change depending on the what was used to make the drug.

Black tar heroin is highly addictive and can cause serious health problems, including overdose and death. If you come into contact with black tar heroin, it is important to seek medical help immediately.

How Can I Tell if Heroin is Being Smoked?

The odor of black tar heroin smoking is typically unpleasant and has been described as smelling like strong sweet vinegar. When heroin is smoked, the fumes produced are breathed in and exhaled soon after.

One thing that can give away the smell of heroin being smoked is how it’s smoked. For example, if someone uses tin foil to smoke heroin, the smell is reminiscent of metallic objects being heated in a fire. Others describe it as similar to the smell of burning plastic. The burning tin foil smell is unmistakable regardless of how you describe it.
