Black Tar Heroin: What Is It, Effects, & Dangers

Table of Contents


Black tar heroin, characterized by its dark, sticky appearance resembling that of roofing tar, is a type of heroin commonly manufactured in Mexico and mainly found in the western United States. The use of black tar heroin, much like powdered heroin, can result in severe physical and psychological health issues, including the development of opioid use disorders (heroin addiction).

 What Is Black Tar Heroin?

Black tar heroin looks different to the more commonly recognized powdered form of the drug. It’s a dark, often hard substance that can also be viscous, much like the tar used in roofing. This form of heroin is typically adulterated with substances of lower quality like charred cornstarch or lactose during its production. This results in a product that is generally less pure and less expensive than traditional powdered heroin.

People usually consume black tar heroin by smoking or injecting it. Injecting black tar involves dissolving and diluting the drug, which can then be administered intravenously, intramuscularly, or subcutaneously. Alternatively, it can be vaporized on foil using a flame and then inhaled with a straw, or it can be mixed with water and heat to create a solution for nasal spray.

Originating primarily from Mexico, where rudimentary processing techniques are used to make the drug, production is not exclusive to Mexico. Black tar heroin is also manufactured in parts of South America, as well Southeast Asia, and Southwest Asia. The drug sometimes goes by the name of heroin acetate, deriving from one of the processes in its production known as acetylation.

The use of black tar heroin carries significant health risks, including the potential for soft tissue infections and vascular sclerosis – the hardening of the arteries. Those who use black tar heroin long-term may also face mental health issues, withdrawal symptoms, and risk addiction. While incurable, black tar heroin addiction is highly treatable.

 Black Tar Heroin Effects

The impact of heroin remains consistent regardless of its form. The notion that black tar heroin is inherently less pure than other types of heroin is not entirely accurate. Contrary to the common perception of white heroin being more refined, it is frequently adulterated with other substances to reduce costs. The purity of black tar heroin is often around 30% due to its less sophisticated production method, although this can fluctuate significantly. That said, the core effects of heroin use remain unchanged and include:

  • Euphoria
  • Decreased anxiety
  • Relief from tension
  • Sleepiness
  • Indifference

From the onset, individuals using black tar heroin will encounter these effects, which are unfortunately the same appealing characteristics that contribute to the drug’s addictive nature. The risk of overdose is present from the first use of black tar heroin, with prolonged use increasing the likelihood of developing additional health complications.

Long-term consequences of heroin addiction include:

  • Sleep disturbances
  • Vein collapse (due to repeated injections)
  • Tissue damage at the drug’s entry site
  • Heart lining and valve infections
  • Development of abscesses
  • Gastrointestinal issues
  • Liver and kidney deterioration
  • Respiratory conditions
  • Psychological disorders
  • Impotence in men
  • Disrupted menstrual cycles in women

 Difference Between Heroin and Black Tar Heroin

While heroin is widely recognized for its addictive potential and adverse health effects, it’s important to distinguish between its various forms, especially the differences between powdered heroin (often referred to simply as heroin) and black tar heroin. 

  • Appearance and texture: The most apparent difference lies in their physical form. Powdered heroin can range in color from white to brown, depending on its purity and the substances it’s cut with. Black tar heroin, by contrast, is dark brown or black, with a sticky, tar-like consistency due to its crude processing.
  • Production and purity: Powdered heroin’s color and texture result from its refinement process and the additives mixed with it. White heroin is often perceived as the purest form, and it’s typically found in the eastern United States and Europe. Black tar heroin, predominantly produced in Mexico, undergoes a less sophisticated processing method, resulting in its characteristic color and texture. 
  • Methods of use: Both forms of heroin can be injected, which is the most dangerous method of use due to the risk of overdose and infectious diseases. However, the sticky, gooey nature of black tar heroin means it’s also commonly smoked or dissolved and snorted, providing some versatility in consumption methods compared to powdered heroin.
  • Health risks: While all heroin use carries significant health risks, the specific form of the drug can influence the type and severity of these risks. Black tar heroin’s impurities and the substances it’s cut with can increase the likelihood of developing venous sclerosis, abscesses, and other infections at injection sites. Powdered heroin, especially when cut with substances like fentanyl, presents a high risk of overdose due to its potent and often unpredictable potency.
  • Geographic availability: Black tar heroin is more commonly available in the western United States, due to its production in Mexico and ease of transport across the border. Powdered heroin, meanwhile, is more prevalent in the eastern U.S. and European markets, where it is often smuggled from Southeast and Southwest Asia.

 Treatment for Heroin Addiction

Addressing heroin addiction requires a comprehensive approach that combines medical and psychological interventions to support recovery and reduce the likelihood of relapse. Effective treatment for heroin addiction typically involves several core components tailored to individual needs:

The first step in treating heroin addiction often involves a medically supervised detox process to safely manage withdrawal symptoms. Medications like methadone, buprenorphine, or clonidine may be used to ease the discomfort of withdrawal and cravings.

MAT is a highly effective approach that uses medications, in combination with counseling and behavioral therapies, to treat substance use disorders. For heroin addiction, FDA-approved medications such as buprenorphine and methadone can help stabilize the brain’s chemistry, block the euphoric effects of opioids, and mitigate withdrawal symptoms and cravings.

Behavioral therapies are central to heroin addiction treatment, helping individuals to modify their attitudes and behaviors related to drug use. CBT (cognitive behavioral therapy) and contingency management are among the most effective therapies, focusing on skill-building, coping strategies, and incentives for sobriety.

Participation in support groups like NA (Narcotics Anonymous) or other community support systems can provide invaluable emotional support and a sense of belonging. Peer support can help maintain recovery goals and reduce feelings of isolation.

Many people with heroin addictions also suffer from co-occurring mental health disorders, such as depression or anxiety. Dual diagnosis programs offer integrated treatment for both the addiction and the mental health condition, addressing both issues concurrently for a more effective recovery.

Sustainable recovery from heroin addiction involves ongoing support and planning. Aftercare can include outpatient counseling, regular check-ins with a treatment provider, sober living arrangements, and continued participation in support groups.

Treatment for heroin addiction is most effective when it is personalized, addressing the unique needs and circumstances of the individual. A comprehensive treatment plan, combining medical intervention, counseling, and support, can pave the way for a successful recovery and a life free from heroin dependence.

It is called black tar heroin due to its tar-like consistency and dark color, which results from the crude processing methods used to illicitly manufacture heroin, leaving behind impurities and giving it a black, sticky appearance.
