What is nyaope? The drug, its effects, and treating nyaope addiction

Nyaope is a heroin-based street drug smoked in a joint with cannabis or tobacco, sold cheaply in South African townships and used most heavily in Gauteng. The same drug goes by whoonga in KwaZulu-Natal, and by unga, iwunga, and sugars elsewhere.

Much of what circulates about nyaope is inaccurate, particularly regarding what goes into it. That inaccuracy has consequences, because families trying to understand what a relative is using often find rumour rather than information.

This article sets out what laboratory analysis of seized nyaope actually finds, what the drug does to the body, why stopping is so difficult, and what treatment involves in South Africa. The article also covers the health risks specific to the way people use nyaope, including the blood-sharing practice known as ‘Bluetooth’.

What is nyaope, and what does the name mean?

Nyaope is a street preparation built on low-grade heroin, ground into a brown or dark powder and mixed with other substances before being sold in small bags. Users typically sprinkle the powder into a cannabis joint or a cigarette and smoke it, though injecting has become more common in recent years.

The drug emerged in the Tshwane townships of Mamelodi, Soshanguve, and Atteridgeville between 2000 and 2006, and spread from there. Names vary by region rather than by content. Gauteng’s nyaope is KwaZulu-Natal’s whoonga, and goes by unga, iwunga, wonga, sugars, or pinch in other communities. Asking what nyaope is in English has no satisfying answer, because the word describes a local street mixture rather than a pharmaceutical substance with a formal name.

One point clears up most of the confusion around all these names. Whatever the preparation is called, heroin is the active ingredient doing the work, which makes nyaope dependence a form of opioid addiction. Our article on what opioids are and how they affect the body covers that wider class of drugs. 

Whoonga in KwaZulu-Natal

Whoonga is the name most commonly used in KwaZulu-Natal, particularly around Durban, and it caused years of confusion because early reporting treated the mixture as a separate drug with its own recipe. National health data now treats the two as one substance. SACENDU, the monitoring network run by the South African Medical Research Council, defines nyaope and whoonga together as street names for low-grade heroin, usually mixed with other substances, sprinkled on cannabis or tobacco, and smoked in a rolled cigarette.

Regional differences show up in how people use the drug rather than in what it contains. Smoking accounts for almost all heroin and opiate treatment admissions in KwaZulu-Natal, where only 2% of patients reported injecting, against 51% in the Western Cape. Men make up the overwhelming majority of admissions in both provinces.

What is nyaope made of?

Nyaope has no recipe. Composition varies between dealers, areas, and batches, which is central to why the drug is dangerous. What the evidence consistently shows is that heroin, or the compounds it breaks down into, provides the active effect.

The most detailed analysis published so far appears in the journal Toxics in 2026, where researchers profiled eight nyaope samples seized from six sites across the City of Tshwane. Testing found a mixture dominated by poppy-derived compounds:

• Heroin and 6-monoacetylmorphine, the compound it breaks down into
• Morphine and codeine
• Oxycodone
• Other opium alkaloids, among them noscapine and papaverine

The same analysis found several substances that have nothing to do with the poppy. Caffeine and paracetamol appeared in all eight samples, both of which dealers commonly use to bulk out street drugs. Individual samples also contained diazepam, methaqualone, chloroquine, and trimethoprim, which means a person buying nyaope has no way of knowing what they’re taking alongside the heroin.

Does nyaope contain antiretrovirals?

The claim that nyaope contains HIV antiretroviral medication is the most widely repeated thing said about the drug, and it remains unconfirmed. A 2025 study of nyaope users in Tshwane states the position plainly: Heroin is believed to be the primary ingredient, while the addition of antiretroviral medication has not been confirmed. The 2026 chemical profiling of Tshwane samples reported no antiretroviral compounds among its findings either.

The rumour does have a basis. Efavirenz, an antiretroviral once widely used in South Africa, has psychoactive effects, and its diversion for recreational use has been documented separately. Efavirenz misuse and nyaope get conflated in reporting, which is how a drug built on heroin came to be described as an HIV medication cocktail.

The distinction has practical value for families. Nyaope dependence behaves exactly like heroin addiction and responds to the same treatment. Treating it as a mysterious local cocktail delays the step that helps.

What about rat poison, pool cleaner, and detergent?

Media reports regularly list rat poison, pool cleaner, bicarbonate of soda, milk powder, and detergent among nyaope’s ingredients. Most of these claims trace back to interviews and reporting rather than laboratory testing, and analyses have not established them as standard components.

The reasonable conclusion is neither reassuring nor sensational. Bulking agents are certainly present, sometimes including substances no one should inhale, and the mixture changes from one batch to the next. A person using nyaope is taking heroin of unknown strength alongside additives nobody has identified, which is a sound reason to treat every purchase as unpredictable.

What does nyaope look like?

Nyaope is usually a brown or dark powder, often compared to soil or cement, which makes it easy to conceal and hard for police to identify on sight. Sellers package it in small plastic bags or folded paper.

Because people mix the powder into a joint before use, the paraphernalia families notice is ordinary: Rolling papers, cigarettes stripped of tobacco, and burnt residue. Where injecting has started, syringes, bottle caps, and cotton wool appear instead. Colour and texture tell you nothing reliable about strength, since neither reflects how much heroin a particular batch contains.

How much does nyaope cost, and where is it sold?

Price is a large part of why nyaope spread so quickly. Users interviewed in the 2025 Tshwane study described bags selling for R25, dropping to R18 or R15 in their area, and as little as R10 in Hillbrow. At those prices a daily habit is within reach of school pupils.

The same research describes transactions taking place openly, with participants saying they could walk straight up to a dealer without hiding. Participants reported nyaope being available in schools and prisons, and one described buying from a police officer in uniform while in custody. Availability on that scale explains why the drug is difficult to escape in the communities where it has taken hold.

The effects of nyaope

Nyaope has the effects of any other opioid, because that’s what it is. Smoked, it takes hold within minutes, bringing a wave of warmth, calm, and drowsiness, and dulling physical and emotional pain. Users describe sliding into a heavy, nodding sleepiness that lasts a few hours.

Short-term effects include:

• Drowsiness and slowed, slurred speech
• Constricted pupils
• Nausea and vomiting, particularly early on
• Constipation
• Slowed breathing, which is what makes overdose lethal
• Reduced appetite and disturbed sleep

Longer-term use brings weight loss, dental problems, persistent constipation, and chest infections from smoking. People who inject also develop damaged veins, abscesses, and skin ulcers. A 2023 systematic review of nyaope research links use to depression and, in one MRI study comparing users with non-users, to a measurable loss of tissue in frontal areas of the brain.

Overdose is the most immediate danger. Signs include very slow or stopped breathing, blue or grey lips, and a person who can’t be woken. Call 10177 or 112 straight away, and place the person on their side while you wait. Fentanyl in the local heroin supply makes the risk harder to predict, as our article on opioids in South Africa explains.

The social damage arrives alongside the physical. The Tshwane research describes school dropout driven by cramps and cravings that made concentration impossible, theft to fund daily use, imprisonment, and rejection by neighbours who assume anyone using nyaope will steal from them. In a related study of families, one mother described her relative’s behaviour on nyaope as aggressive, saying “he was a different person”, to the point that the family became afraid of him.

Why nyaope is so hard to stop using

Researchers in the Tshwane study note that many people become dependent soon after first trying nyaope, and the pharmacology explains why. Heroin produces tolerance quickly. The amount that once produced a high stops working, and the dose climbs. Physical dependence follows, and at that point the daily bag is no longer about feeling good.

Withdrawal is what keeps people using. Opioid withdrawal begins within 8 to 12 hours of the last dose, bringing stomach cramps, vomiting, and severe agitation. Our article on opioids sets out the full withdrawal timeline. One participant in the Tshwane study described withdrawal so bad he thought he was dying. Another left school in grade 10 because concentrating through the cramps was impossible.

A person in that position faces a choice between hours of acute illness and a R15 bag that ends it within minutes. Willpower is rarely the deciding factor, which is why medically managed withdrawal changes the odds so substantially. Our medical detox programme treats those symptoms with medication under clinical supervision rather than leaving a patient to endure them.

Bluetooth: Blood-sharing and its risks

As injecting has spread among nyaope users, a practice known as ‘Bluetooth’ has emerged. A person who has injected draws blood from their own vein and passes it to another user, who injects it in the hope of sharing the effect. The practice tends to appear where people can’t afford their own bag and withdrawal is already setting in.

Researchers describe Bluetooth as a direct route for transmitting blood-borne viruses, including HIV, hepatitis B, and hepatitis C, on top of the risks that needle sharing already carries. South Africa’s HIV prevalence makes the exposure particularly serious.

Families who discover that a relative has been injecting, or sharing blood, should treat testing as urgent rather than shameful. HIV and hepatitis testing is free at public clinics, and both conditions are treatable. A nyaope user who is also living with HIV needs both conditions managed together, which is one reason a treatment facility with medical staff on site is preferable to an unsupervised detox.

What the treatment data shows about nyaope

Searching for nyaope statistics turns up very little, and there’s a straightforward reason for that. South Africa’s national drug monitoring system doesn’t count nyaope separately. SACENDU, which collects treatment admission data from centres across the country, states in its reporting that it has folded nyaope and whoonga into the heroin-related category to improve the accuracy of national surveillance.

Two things follow from that decision. Treat any figure presented as a nyaope-specific national statistic with caution, because the monitoring system doesn’t produce one. More usefully, the heroin and opiate numbers already include nyaope admissions, which makes them the best available guide.

The most recent SACENDU research brief, covering January to June 2025, reports that heroin and opiates accounted for 7% of all treatment admissions nationally, down from 10% in the previous period. Smoking remains the main route of use at 69%, with injection at 28%. Admissions among people aged 18 and younger stay infrequent, and the national mean age of patients in treatment sits in the early thirties.

One caveat applies to all of these figures. SACENDU counts patients who reach a treatment centre rather than everyone using drugs, which understates the true scale in communities where specialist care is hard to access. That gap is widest in exactly the areas where nyaope use is concentrated.

Is nyaope legal in South Africa?

Nyaope is illegal. Heroin, its active ingredient, is prohibited, and in 2014 the Department of Justice specifically listed nyaope as an undesirable dependence-producing substance under the Drugs and Drug Trafficking Act, closing an argument that had previously complicated prosecutions. Possession and dealing are both criminal offences.

The Tshwane research suggests enforcement falls unevenly. Participants described being arrested and prosecuted for theft rather than for nyaope itself, while buying the drug openly. Whatever the enforcement picture, a criminal record follows many users, which becomes another obstacle to employment later in recovery.

Treatment for nyaope addiction

Nyaope addiction is treatable, and clinicians approach it as opioid dependence, because that’s the pharmacology involved. Treatment usually runs in two stages. Medically managed withdrawal handles the physical dependence over roughly a week, and a longer period of therapy then addresses what the drug was doing for the person and rebuilds a life that functions without it.

Detox on its own has a high relapse rate. Physical withdrawal resolves in days, while cravings, sleep problems, and low mood persist for months, and returning to the same street, the same friends, and the same dealer usually undoes the progress. A residential programme creates distance from all three during the period when relapse is most likely.

Tolerance also falls fast during abstinence, which creates a specific danger. Someone who relapses after a few clean weeks and uses their old amount can overdose on a dose their body previously handled. Anyone leaving treatment, or coming out of prison, needs that spelled out.

Where to get help if you can’t afford private treatment

Private inpatient drug rehabilitation is out of reach for many families affected by nyaope, and the drug is concentrated in communities where that’s most true. State and subsidised options exist. Our guide to free and subsidised rehabilitation centres in South Africa lists government facilities and funded non-profit services by province, with contact details, and includes SANCA branches across Gauteng, where nyaope use is heaviest.

Public treatment usually involves a waiting list and an assessment through a social worker or a local clinic. Starting that process before a crisis, rather than during one, generally produces a faster result.

Treatment at Houghton House

Houghton House treats opioid addiction, including nyaope and heroin dependence, starting with medically supervised detox and continuing into a 30-day primary programme of individual therapy, group work, and family involvement. Houghton House is a licensed psychiatric hospital, and our on-site medical staff monitor patients throughout withdrawal. Our dual diagnosis programme treats addiction and a co-occurring mental health condition at the same time.

Substance use disorders are Prescribed Minimum Benefits. This means every registered medical scheme must cover addiction treatment. Our page on medical aid cover for rehab explains how claiming works.

Advice for families

Families living with a relative’s nyaope use carry a particular strain, because theft from the household is common and trust erodes quickly. A few things help.

• Separate the person from the behaviour when you talk, and describe what you have seen rather than what you assume
• Secure money and valuables without announcing it as punishment, since removing the opportunity reduces conflict
• Expect withdrawal to drive desperate behaviour, and understand that a relative in that state isn’t reasoning normally
• Get your own support, through a counsellor or a group such as Nar-Anon, which runs meetings for relatives of people who use drugs, rather than managing it alone
• Keep the offer of treatment open and specific, including which facility and how it would be paid for

Our addiction support groups page lists family meetings around the country.

Frequently asked questions about nyaope

Is nyaope the same as whoonga?

Yes. Whoonga is the name used mainly in KwaZulu-Natal for the same heroin-based street mixture that Gauteng calls nyaope. Unga, iwunga, wonga, sugars, and pinch refer to the same thing in different communities. Composition varies between batches and areas, though the active ingredient is heroin in all of them.

What is nyaope made of?

Nyaope is mostly heroin. In a 2026 study, researchers tested eight samples collected around Tshwane and found a mixture dominated by heroin and other compounds from the opium poppy. Caffeine and paracetamol showed up in all eight, which dealers commonly add to bulk out the powder, and some samples also contained sedatives and other medicines. Laboratory testing hasn’t backed up the rumours that nyaope contains antiretrovirals, rat poison, or pool cleaner.

How many people in South Africa use nyaope?

No reliable national figure exists for nyaope specifically, because SACENDU folds nyaope and whoonga into its heroin and opiate category. Heroin and opiates made up 7% of treatment admissions nationally in the first half of 2025. Separate research estimated that between 215,000 and 425,000 people were using heroin daily in 2020, which is the closest available indication of scale.

How long does nyaope withdrawal last?

Acute withdrawal starts within 8 to 12 hours of the last dose, peaks between the first and third day, and eases over roughly a week. Sleep problems, low mood, and cravings usually continue for months afterwards. Most relapses happen during that stage, which is why ongoing support counts for so much.

Can nyaope addiction be cured?

Clinicians treat addiction as a condition to manage rather than cure, in the same way as diabetes or hypertension. People recover from nyaope dependence and stay in recovery for decades, working, raising families, and rebuilding relationships. Getting there generally takes medically managed withdrawal, a period of intensive treatment, and support that continues well after the programme ends.

How do I get someone into rehab if they don’t want to go?

You can’t force an adult into rehab except through a court-ordered process under the Prevention of and Treatment for Substance Abuse Act, which is rarely the best starting point. What works more often is a planned family conversation with clinical guidance behind it, timed for a moment when the person is not in acute withdrawal, with a place already arranged. Our team can help you prepare for that conversation.

Getting help for nyaope addiction

Nyaope dependence is heroin addiction under a local name, which means it responds to the same treatment as any other opioid problem. The barriers people run into are usually practical, including cost, waiting lists, and distance, rather than any question of whether recovery is possible.

If you or someone in your family is using nyaope, speak to our admissions team on 011 787 9142. A first conversation is free and carries no obligation, and if private treatment isn’t affordable, our team can point you towards the state and subsidised options listed on our resources page.
