The Different Types of Heroin & What They Look Like

There are several different types of heroin. Each type is extremely addictive and dangerous despite the differences in purity. These include:4

Black Tar Heroin

Black tar heroin is a dark brown or black sticky substance that looks like a hard ball. It is the least pure form of heroin and often contains other substances like talcum powder or rat poison (strychnine).

Its consistency makes it difficult to inject but can be diluted in water and heated for injection. Otherwise, it can be smoked using aluminum foil or ingested in another way.

Brown Heroin

Brown heroin is sometimes called brown powder. It’s a powder that’s similar to pure white heroin but tends to have a grittier texture because it isn’t as pure. It’s usually smoked but can be injected or snorted.

Asian Heroin

Asian heroin comes in various colors, depending on where it comes from. These include:2

  • White
  • Beige
  • Yellow
  • Pink
  • Orange

It comes in powder form and resembles ground-up candy or chalk.

Gunpowder Heroin

Gunpowder heroin is a stickier and more potent form of black tar heroin. It has a crumbled texture similar to dried coffee grounds. It’s commonly found on the West Coast of the United States. 

Purple/Blue Heroin 

Purple or blue heroin, or Purp, is one of the deadliest forms of the drug. It is mixed with fentanyl and carfentanil, a tranquilizer used to anesthetize elephants. A dose of purple heroin, as small as 20 micrograms (the size of a grain of sand), is enough to kill a user.

White Heroin 

White heroin is the purest form of heroin; the whiter the color, the purer it is. It often appears as a fine white powder. It’s important to know that, like most heroin, its purity does not make it safe.

Pills and Tablets

Heroin can also come in tablet or pill form. These light blue pills are often called “Mexican Oxy” or “heroin pills.”

Heroin pills are deadlier than regular heroin because they contain a significant amount of fentanyl. It’s also often mistaken for its prescription counterparts, like oxycodone or hydrocodone.

These pills are sold as a version of oxycodone, despite being three to six times as dangerous as their prescription counterparts. Using these pills can lead to significant health problems.

What Does Heroin Smell & Taste Like?

Pure heroin has very little odor because its smell usually comes from the substances cut into it. It often smells like vinegar due to the process that makes it more acidic. It may also smell like vitamins or medicine.

On the other hand, heroin has a bitter taste but it depends on how it’s cut. Cutting heroin with something acidic gives it an acidic flavor while cutting it with sugar makes it sweet. Meanwhile, black tar heroin has a chemical taste.

How Does Heroin Work?

Heroin binds to the brain receptors and activates the mu-opioid receptors (MORs). This causes a temporary release of dopamine, which is a neurotransmitter responsible for feelings of pleasure and satisfaction.1

This dopamine rush makes you feel good and increases the risk of repeated use. However, not all substances interact with the brain in the same way.1

The way you use heroin can affect the intensity of its effects. For example, injecting heroin is typically more immediate and intense than smoking heroin.1

How Addictive is Heroin?

The dopamine rush you experience from heroin can quickly cause an addiction. This is because when an external trigger causes the release of neurotransmitters repeatedly, the brain learns to depend on that trigger.1,4

Over time, the brain will need more heroin to achieve the same effects, leading to substance use disorders. Factors that affect how you develop an addiction to heroin include:1,4

  • How you use heroin
  • How often you use it
  • How quickly it reaches the brain
  • The potency of heroin

For many people, heroin addiction begins with dependence on prescription painkillers prescribed to treat a medical issue or to alleviate pain after a medical procedure. However, once an addiction develops, you may turn to heroin when you can no longer access prescription painkillers.1

Who is at Risk of Heroin Addiction

Anyone who uses heroin is at risk of developing an addiction. However, some factors that increase the risk of developing an addiction include:4

  • Family or personal history of addiction to any substance
  • Heavy use of tobacco
  • History of anxiety or depression
  • Exposure to high-risk environments
  • History of risk-taking behavior
  • Use of prescription painkillers
