Mainly produced in Mexico and smuggled across the southern border, black tar heroin has quickly risen to become the most predominant type of heroin available in the U.S. market.
Like other types of heroin, black tar has a high potential for physical and psychological dependency. In high doses, or mixed with other drugs, it can also be deadly.
Mexican Black Tar Heroin
The majority of black tar heroin is produced in Mexico and brought into the United States across the southern border.
Traditionally only available in the southern and western states, this form of heroin has become readily available in markets across the nation.
Since 2015, most of the heroin sold in the U.S. has come from Mexico.
Side Effects Of Black Tar Heroin
The side effects of using black tar are similar to the side effects of using other types of heroin and opioids.
Some side effects include:
- feeling of euphoria
- itching
- constipation
- warm, flushed skin
- constricted pupils
- slurred speech
- dry mouth
- weight loss
- mood swings and irritability
People using black tar heroin in 2026 face another major risk: fentanyl contamination. Illicitly manufactured fentanyl is increasingly mixed into the heroin supply, sometimes replacing it entirely.
Fentanyl is dramatically more potent than heroin, and a dose that looks identical to a previous batch may be lethal. Fentanyl test strips can detect contamination before use and are available at many pharmacies and harm reduction organizations.
Health Issues Related To Black Tar Heroin Use
Heroin use can lead to many different health issues, especially with long-term use.
Some health issues that can arise due to the use of black tar include:
- collapsed veins
- mental health issues
- sexual dysfunction
- higher risk for Hepatitis B and C
- kidney disease
- liver disease
- skin infections
- wound botulism
Anyone using black tar heroin or living with someone who does should keep naloxone on hand. Naloxone reverses opioid overdose and is available over the counter at most pharmacies without a prescription.
If you suspect someone is overdosing, call 911 immediately and administer naloxone if available. Because much of the current heroin supply contains fentanyl, you may need to use multiple doses of naloxone.
Most states have Good Samaritan laws that provide limited legal immunity to people who call for help during an overdose.

Recovering From Heroin Addiction Is Possible
According to SAMHSA’s 2023 National Survey on Drug Use and Health, approximately 1.1 million people aged 12 or older reported using heroin in the past year, and around 1 million met the criteria for heroin use disorder.
Overdose deaths involving heroin have shifted significantly in recent years as illicitly manufactured fentanyl has increasingly displaced heroin in the illicit supply.
With the nation in the grips of an opioid crisis, there are a growing number of treatment options available to help those struggling with heroin addiction.
Achieving recovery from heroin addiction is possible.
Black Tar Heroin FAQs
Find answers to the most frequently asked questions about black tar heroin.
Where Does Black Tar Heroin Come From?
Black tar heroin comes from the opium poppy plant. This plant is grown all over the world, including parts of Southeast Asia, Southwest Asia, and Latin America.
Most of the black tar heroin in the United States comes from Mexico and Colombia.
What Is In Black Tar Heroin?
Black tar heroin is processed and filtered using a variety of chemicals, but its primary ingredient is morphine. Morphine is a naturally occurring opiate that is processed from opium.
In addition to morphine, black tar heroin may contain a number of cutting agents, including anesthetics, fillers, and other illicit drugs.
How Is Black Tar Heroin Made?
Black tar heroin is processed from morphine, which comes from the opium poppy plant. From here, a series of steps must be taken to refine morphine into diacetylmorphine (heroin).
The manufacturing process for creating black tar varies according to place of origin and techniques used by the manufacturer.
Can You Shoot (Inject) Black Tar Heroin (IV Use)?
Injection is the most common route of administration for using black tar. In black tar form, heroin can be injected into a vein or muscle by diluting and heating it.
Injecting black tar heroin is particularly dangerous due to its impure nature.
Those who inject are at risk for a variety of health complications including:
- venous sclerosis
- hardening of the veins
- vein collapse
- other bacterial infections
People who inject black tar heroin can reduce health risks by using sterile needles and supplies every time, so make sure to never share needles, cookers, or cotton.
Syringe service programs (SSPs) provide free sterile injection equipment without judgment and can connect people with naloxone, wound care, and treatment when they are ready.
Find local SSPs through the North American Syringe Exchange Network.
Can You Snort Black Tar Heroin?
Although injection is the most common method of use, black tar heroin can be administered in other ways. Insufflation, or snorting, of the substance is possible.
This can be done by heating the drug and mixing it with water. From here, it can be snorted up the nose using a glass tube or medicine dropper.
Can You Smoke Black Tar Heroin?
Black tar can be heated and inhaled. Rather than actually smoking black tar heroin, the addicted individual vaporizes the drug by indirectly heating a piece of foil that contains the substance.
The vapor produced from this is then inhaled using a straw or tube. This is commonly referred to as “chasing the dragon.” This can be detected by the strong, vinegary smell of black tar heroin.
What Is The Treatment For Heroin Addiction?
Overcoming heroin addiction is a multi-step process that begins with detox. Detoxing from heroin involves stopping your use of heroin, which can lead to heroin withdrawal.
People who are addicted to heroin may need further treatment to help them stay off heroin and fully heal from the physical, psychological, and emotional effects of drug addiction.
Treatment for heroin addiction may involve:
- medication
- individual counseling
- behavioral therapy
- group therapy
- relapse prevention
- aftercare support
Treatment for heroin addiction can come in the form of inpatient rehab or outpatient rehab. This is offered by select rehab centers that specialize in treating heroin addiction.
