What does heroin look like?
Heroin comes in multiple forms from all corners of the world. Where the drug comes from can affect how it appears as well as the purity of the drug and what it has been cut with. Below are the most common forms of heroin and what they look like.
Black tar heroin
As the name suggests, black tar heroin is often black or dark brown and has a sticky tar-like texture. The appearance and feel of this form of heroin results from the way it is processed, often low quantities of pure heroin heavily diluted with other substances.
As it is less pure it can be easily melted down and injected and is often mixed with many other dangerous substances (such as the synthetic opioid fentanyl). It is also one of the cheapest forms of heroin, making it more likely to be addiction-forming.
The purest form of heroin, diamorphine hydrochloride, is far more expensive than other forms of heroin and is often white/off-white. Pure heroin is often diluted with other chemicals in order to increase quantities which can cause it to appear slightly pink, beige, or brown. White heroin is rarely smoked due to its high burn point and is more regularly snorted or injected.
The more pure heroin is cut with other substances the less potent it becomes and the more the color changes. Brown powdered heroin is one of the most common variations and is formed early in the purification process. Brown heroin doesn’t dissolve well and is therefore often smoked.
Heroin is produced all over Asia and often ends up being smuggled into the west. Heroin from Southwest Asia tends to be similar to brown powdered heroin whereas Southwest Asian heroin tends to be purer and closer to the substances white powder form.
What does heroin smell like?
When heroin is in its pure form it is often completely odorless. The smell of heroin comes from when it is processed and cut with other chemicals. Like with its color, the smell of heroin changes depending on what other substances have been added to it.
The most commonly described smell of heroin is a bitter, vinegar-like scent. The vinegar smell comes from the synthesis process and the more refined the heroin is the less bitter it will smell. This is why black tar heroin tends to be far more pungent as the chemicals and bacteria have not been fully removed.
The purity of heroin also affects how long it stays in your system. Click here to learn more about how long heroin stays in your system.
What does heroin taste like?
Much like the smell of heroin, its taste varies greatly depending on the substances it is cut with. Purer heroin is often cut with subtle tasting substances in small amounts such as flour, baking soda, or powdered milk and will often have little to no taste. Brown heroin is often cut with stronger, more hazardous chemicals such as laundry detergent and will as such have a bitter or acidic taste.
Other warning signs that someone is using heroin
Like most forms of substance use disorder, someone who is struggling with heroin addiction will often display certain indicators, These can include:
- Drowsiness, excessive yawning, or nodding off
- Weight loss or neglecting appearance/hygiene
- Itching or scratching
- Needle marks on the arms, legs, or feet from injecting heroin
- Finding drugs, syringes, or other drug paraphernalia
- Lying or being overly secretive

Helping someone suffering from a heroin use disorder
Expressing care and concern for a person can be helpful, but it’s important to recognize that often, a heroin addict will not stop using until they have recognized there is a need to change. Often, this happens when they ‘hit rock bottom’ or experience a ‘wake-up call’ after a negative or scary experience with heroin.
The best way to identify the right treatment is to set up an appointment with a local addiction treatment center or a licensed addiction specialist who can provide recommendations for treatment.
Seeking treatment greatly increases the likelihood of remaining clean and sober, helping people overcome their addictions and get their lives back on track.
